Узнаем IP по e-mail

Мне часто приходят письма от спамеров, "доброжелателей" и прочих юзеров, которые думают что они анонимны... Развеем же их надежды. Вот, к примеру, пришло мне письмо от одного спамера, рассылающего мне бюллетень "$#*зит", который мне не нужен. Берем его письмо, жмем (в Аутлуке) Файл, потом Свойства, закладка Подробности. Вот что мы видим (помеченные "#" строки - мой комментарий):

Такой логин, скорее всего, говорит о том, что провайдер выделяет IP адреса динамически (то есть он в Инет заходит с обычного дайл-апа). Да, это усложняет нашу задачу:

Узнай как можно больше подробностей

Начнем наше разбирательство по этому случаю: первый е-мэйл, указанный в Return-path'е - подставной (100%). Зачем спамеру давать свой реальный ящик? А mail.bb-online.dk - подставной сервер посылки почты. Этим я занялся первым делом. Зашел на www.bb-online.dk и узнал, что это немецкий провайдер, предоставляющий размещение виртуальных серверов, и главное, что у него открыт 25 порт для всех - то есть через него можно слать почту без проблем. Вот этой фишкой и воспользовался спамер, точнее не он сам, а тот, кто продал ему e-mail адреса жертв (мой тоже, правда я ума приложить не могу, откуда он там взялся - скорее всего, перепродажа адресов). Очень интересным показался мне адрес sucsess@fwp.net, поэтому я зашел на www.fpw.net, который оказался сайтом Yelow Pages (то есть сайтом с кучей ссылок, или рубрикатором, по-русски). Мне там предложили оставить свой e-mail, на что я ответил вежливым отказом. Все ясно, fpw - это и есть тот сервер, который продал мой e-mail и послал мне спам. Вся эта информация, конечно, нужна, но хотелось узнать, кто же настоящий заказчик.

Это можно сделать так:

Посмотреть на последний заголовок Received From - tengu.host2u.net. Оказался лажой - я это тоже проверил через Интернет Маньяка и просто написав этот адрес в броузере.

Проверить IP. А вот IP в квадратных скобках - интересный... Я сделал Host LookUp (это делается любой прогой, типа CyberKit) и увидел www.eric.com. Ну а дальше все ясно. Бегом на сайт, смотрим about, читаем Contacts и все. Вот там-то я и узнал о боссе спамера.

FAQ: How to find people's E-mail addresses

Index
Introduction

A question which appears frequently on the Usenet is, "I know someone's name, and I think they might have an electronic mail address somewhere. How can I find it?"

There are many different techniques for doing this. Several of them are discussed below. Your best bet is to try the pertinent methods in this posting in the order in which they are listed (well, sort of; at the very least, please try all the pertinent methods which do not involve posting queries to soc.net-people before resorting to that).

I've listed "Direct contact" near the end of this list because, for some reason, people seem to be reluctant to call people on the telephone or write them a paper-mail letter asking what their E-mail address is, as long as there is even a remote chance that it might be found without asking. This attitude is somewhat counterproductive, since in most cases, it is much easier to get someone's E-mail address by asking them than it is by following the other methods outlined below. Furthermore, even if you do manage to find an E-mail address using one of the on-line methods described below, it is not guaranteed that the person at the other end of the line checks that address regularly or even that it is the correct address.

Therefore, if you do have a telephone number that isn't too expensive to call, or if you have a paper-mail address and aren't in too much of a hurry, you can probably save yourself a lot of trouble by skipping all of the on-line methods listed below and going directly to "Direct contact."

Avoid public distribution of individuals' addresses

It is considered rude to widely distribute (e.g., in a Usenet posting) a person's E-mail address without his/her prior consent, even if the address is publicly available using one of the techniques described below or some other technique.

It might seem that having one's E-mail address listed in a publicly accessible database is equivalent to distributing it, but this is not the case in practice, for three primary reasons:

In summary, if you want to advertise someone's E-mail address, get his/her permission before you do it. Besides, if you're going to advertise an address, it's a good idea to make sure it works first, and writing to it for permission is a good way to do that.

Web Searches

E-mail and phone directories

Entry Changed: Tue Jan 23 2001

Several organizations let you search for addresses by filling in and submitting a form from your Web browser. In many cases these services populated their databases by scanning for addresses in USENET news postings. My list below is fairly short; there is a longer list at Electro-Byte Technologies.

Altavista

Entry Created: Fri Jul 5 1996

Digital's Altavista search engine indexes Web pages and Usenet postings. If you suspect the person you are looking for has created a web page or posted to Usenet, you may be able to find them this way. National white pages

Directory Protocols PH and WebPH

Entry Changed: Thu Apr 1 1999

PH, is a system for managing "phone books." WebPH is a World-Wide Web interface PH. If a site you are interested has installed it, you can look up people from that site by filling in a query form. Unfortunately, there is no convention for how to guess where to find the WebPH or PH server given the site name. LDAP

Entry Created: Thu Apr 1 1999

LDAP, is a "Lightweight Directory Access Protocol". PH is used more heavily at colleges and universities; LDAP seems to be used more by commercial organizations.

Other Techniques

College and School Email Addresses

The College Email FAQ describes the account and E-mail address policies for graduate and undergraduate students at many universities and colleges. If you are looking for a university/college student, check those postings for the university or college in question and follow their instructions for finding out more.

This FAQ is also posted regularly to soc.college as a collection of postings whose subjects start with "College Email Addresses." If the postings have expired at your site or has not been posted recently, you can get a copy of them using the instructions below.

If the university has a PH (phonebook) server, it may be listed in the Colleges and Universities PH server directory.

ClassMates lets secondary school alumni freely register their e-mail addresses; the database covers US, Canada, and American Overseas high schools (2 million entries as of August, 1999). Searches require a fee.Alumni.NET has a smaller database (750,000 as of August 1999) but does not charge for searches.

Curious Cat Educated Connections indexes colleges, high schools, and grade schools in the USA, Canada, and Australia. You can register so that school friends can find you. Usenet-addresses server

If you think that your target may be on the Usenet and may have posted a message to the Usenet at some point in the past, you might be able to find his/her address in the Usenet address database on the machine rtfm.mit.edu.

To query the database, send an E-mail message with "send usenet-addresses/name" in the body of the message. The "name" should be one or more space-separated words for which you want to search; since the search is fuzzy (i.e., all of the words you specify do not have to match), you should list all of the words you think might appear in the address, including (for example) first and last name, possible username, and possible components of the host name (e.g. "mit" for a person who you think is at MIT). The case and order of the words you list are ignored.

Note that multiple requests can appear (on separate lines) in mail to the mail server, but each request will be answered in a separate message.

In many cases, you will get a list of quite a few matching addresses, and you will have to go through it looking for ones that may be the one you're looking for. However, the mail server will return a maximum of only 40 matches.

Note that the usenet-addresses database is accessible via WAIS (in fact, the script that does mail server searches is actually just a front-end to a WAIS database) on two different hosts: rtfm.mit.edu and cedar.cic.net. In both cases, the database is called "usenet-addresses" and is on port 210. Note that the version on rtfm is slightly more up-to-date with respect to the master address list than the version on cedar. If you don't know what WAIS is, then don't worry about this paragraph; if you're curious, see the "comp.infosystems.wais" newsgroup.

For more details about how to use the database, send the command "send usenet-addresses/help". Inter-Network Mail Guide

If you know which network/service your target has an account on (e.g. CompuServe, Fidonet), then the "Inter-Network Mail Guide" posting in comp.mail.misc *may* be able to provide you with some help, although it probably will not be particularly helpful unless you have some sort of address to start with (a small number of networks use full names as addresses, and the posting mentions when this is the case, but it doesn't apply in very many cases).

See the instructions below for getting a copy of this posting if it isn't available in comp.mail.misc at your site. whois/nicname

Entry Changed: Sat Dec 6 1997

Whois is the internet user name directory service. It's available on some UNIX systems as a command called "whois" or "nicname". Do

whois help

or

nicname -h

to get a help message. The whois and nicname programs will check the database maintained at rs.internic.net (or nic.ddn.mil for U.S. military sites) for the given names. For example,

nicname <name>

or

whois <name>

or

whois -h <host> <names>

where <host> is some site with a whois server. This is only useful for people listed in the database. Many regional networks and some universities maintain their own NICs.

You can also get some of this information by telneting to rs.internic.net and running whois and host there, or to nic.ddn.mil if you are looking for U.S. military personnel. Alternatively, you can issue a single command to the whois.internic.net server by typing "telnet whois.internic.net whois" in order to connect to it and then typing the command and hitting return; the "help" command will return several screens full of text, so if you need help, you should use a utility such as "tee" or "script" to capture the help message and save it for future reference.

If you do not have Internet access, you can send mail to query the "whois" database; send a message with "help" in the body to find out more information.

Some sites run local "whois" databases to provide information about people inside their organizations. The only way to find out if your site runs such a database is to ask someone locally about it (see "Get more help locally" below), and the only way to find out about such databases at other sites (assuming, of course, that those databases are not mentioned in any of the other sources listed in this document) is to contact responsible individuals at those sites and ask (see "Finding a host name and asking someone there for help" below). Other whois databases

Quite a few other sites also run "whois" databases that can be connected to over the Internet using the whois protocol (using either the "whois" program or "telnet hostname whois" as described in the previous section). Some of those sites are listed here, and others are listed in a separate list, described in more detail below.

The Ohio State University runs a "whois" database (on the machine "osu.edu") that has all of the faculty, staff, and students listed. It responds to "whois" queries in the normal fashion, or you can just send mail to firstname.lastname@osu.edu and it will try to deliver e-mail if the person has registered an e-mail address. You can also telnet to osu.edu and look-up a person. If you are unsure of the spelling this is a good way, as it does a soundex type search so exact matches are not necessary. No password is necessary.

RIPE (a cooperative group of several European Internet providers) runs a "whois" database, with RIPE information, on "whois.ripe.net"; it is a European counterpart to "whois.internic.net".

Matt H. Power of MIT <mhpower@athena.mit.edu> has compiled and maintains an extensive list of sites that run "whois" servers. The file can be retrieved via anonymous ftp from /pub/whois/whois-servers.list on sipb.mit.edu.

In addition to E-mail addresses for individuals, "whois" servers often also contain contact information about domains. For example, asking whois.internic.net's server for information about "mit.edu" would tell you to look up "mit-dom" in order to get information about MIT's domain, and doing that would give you contact information about the people responsible for administrating that domain, including the handles of those individuals, which you can then look up to get still more information about them. Other directory services

There are several other directory services you may be able to use to search for your target.

The person you are searching for may be using Pobox.com, which provides permanent email forwarding addresses You submit to a searchable database your real name and some biographical information; you receive short, memorable email aliases at pobox.com that forward to your current real mailbox. Whatever your real address is, you can be found at and mailed through pobox.com. Pobox.com is growing very quickly and has amassed a substantial database.

The IBM Corporate Internet Gateway provides a directory of users (which I believe contains only IBM employees, although I'm not certain) that is available to anyone who can send E-mail to it. If your target works for IBM (or you suspect s/he does), then this might be useful to you.

To use it, send mail with the command "whois lastname, firstname" in the subject or body of the message. If you are unsure of the spelling of the last name, use an asterisk (*) to indicate that the last name should be treated as a prefix, rather than a complete name. The first name is always treated as a prefix. For example, "whois Smith*, R" would return all people with a last name starting with "Smith" and a first name starting with "R", while "whois Smith, R" would return only those people with exactly the last name "Smith" and a first name starting with "R".

Users of the directory are limited to 25 name searches per day. Each name that results is counted as a separate name search. For example, a single "whois Smith, R" that found Rodger Smith, Robert Smith, and Reginald Smith would count as three name searches. Multiple requests may be made in a single note provided that the number of names found does not exceed the daily limit of 25.

RPI runs a white pages server for people interested in the field of communications.

BITNIC (the BITNET Network Information Center) runs a name server of more general interest.

There is an X.500 white pages service run by UNINETT. Furthermore, there is software for UNIX available for use as a convenient interface to the service. It is available for anonymous ftp in ~ftp/directory/directory.tar.Z on the machine nac.no. Finally, if the administrator of your site registers your organization with UNINETT (instructions about doing so are available with the software just mentioned), people from your site can then register in the database so that other people can look them up in it.

AT&T Bell Labs runs a mailer on the host "att.com" that can get mail to about 400 employees in the Research Area of Bell Labs using their names as addresses. You can send mail to "lastname@att.com" or to "initials.lastname@att.com", where "initials" consists of one or more initials separated by dots. If the name is ambiguous, you will get a bounce message indicating several possible matches, and the appropriate address to use for each.

Tim Pozar has set up a WAIS server that contains the FidoNet email addresses of Sysops of FidoNet BBSs. You can access it by connecting to the "nodelist" WAIS database on port 210 of kumr.lns.com; use the name(s) for which you wish to search as your search keywords. See above for more information about WAIS.

Information about hosts in the "ca" Internet domain (i.e., hosts in Canada) Is accessible via anonymous ftp to ftp. You can get site domain names and host names, as well as the names and addresses of contact people for individual sites. For more information, retrieve the file /ca-domain/Introduction via anonymous ftp, or send a mail message to the mail server with "send ca-domain Introduction" in it. Finding a host name and asking someone there for help

If you know the organization, company, or whatever at which your target's account is likely to be located, then you might be able to get your hands on the host name of a machine at that location. Once you've done that, you can usually write to someone responsible for E-mail support at the site and ask for help finding the address you are seeking. See the section on 'finding host names' below.

Once you've got a host name and the person to contact, you need to figure out how to get the mail there, if it's on a network you don't know how to reach. See the "Inter-Network Mail Guide" posting referenced above if you need help with that.

If you do go this route, make sure you provide as much information as you can about the person whose address you are seeking; remember that the more detailed (and polite!) you are, the more likely it is that the person you are contacting will be able to help you. Remember, too, that the person you are contacting is probably very busy, and responding to requests like yours is probably not one of his/her highest priorities, so be patient. Using 'finger'

Entry Changed: Mon Sep 2 1996

Finger is a user information lookup program. If you've found a potential host name for your target using one of the other methods described here, and if you have direct access to the Internet, then you may be able to use the "finger" program/protocol to look up your target at a remote site. To finger someone at another site, you generally type "finger name@host". Andrew Starr maintains the Finger FAQ. Some sites provide Web-based interfaces to finger, such as Middlebury College. Knowbot Information Service

The "Knowbot Information Service" (KIS) is another white pages service. For more information about Knowbot, use the "man" command after connecting via telnet or in the body of your E-mail message. In addition, info.cnri.reston.va.us' KIS server can be reached using the Internet "whois" protocol described above. Searching LISTSERV mailing lists

Entry Changed: Tue Jul 4 1995

Many sites around the network are running the VM/CMS LISTSERV package for managing mailing lists. If you have some reason to believe that a particular user may be a member of a mailing list on a LISTSERV site, you can ask that LISTSERV to send you a membership list and search it for your target.

To do this, send mail to listserv@host (if "host" is a BITNET host, try using listserv@host.bitnet; if that doesn't work, you'll have to ask someone at your site how to send mail to BITNET hosts). In the body of your message, include the command "review list-name", where "list-name" is the name of the mailing list you wish to search.

Alternatively, sending mail to the server with the line

WHOIS <name>

may catch the person. For example, listserv@buacca.bu.edu. This is an unlikely option. It also does not work with all listserv implementations.

If you don't know what LISTSERV is and dont' know of any LISTSERV sites or mailing lists, then this technique probably isn't worth bothering with. Direct contact

If you have a paper mail address or telephone number for your target, call them or write to them and ask for an E-mail address.

In that case, you might encounter the somewhat common situation where your target knows s/he has an E-mail address, but s/he doesn't know what it is. If this happens to you, then give him/her your E-mail address and ask him/her to send you mail (and if s/he can't figure out how, tell him/her to get someone at his/her site to help). The odds are that when you get his/her message, it'll contain a valid return address in it. Get more help locally

Often, the postmaster at your site (or whomever is responsible at your site for answering mail- related questions) has a large amount of knowledge that will help him/her to help you find the answer to your question. If you have been unable to find the answer for yourself, check with people locally and see if one of them can help you out. postmaster

Entry Changed: Thu Jul 1 1993

Most sites have an individual responsible for network and mail operations at the site, usually with the userid of 'postmaster'. These people are usually very busy, so before bothering one of them, try telephoning the person you are trying to reach. Long distance is expensive for you, but less expensive, globally, than the postmaster's time. The one reasonable exception is if you're sending mail and getting messages in response that suggest some sort of mail system problem; you might report the problem to postmaster at your own site, who may in turn contact postmaster at the destination site.

Many postmasters will refuse to answer questions about user identification, for reasons of privacy, though they may be willing to forward your address so your intended recipient can write to you. The last resort -- soc.net-people

If all the methods above have failed, you can consider posting a message to soc.net-people asking for help locating your target. Before doing so, however, you should read the "Tips on using soc.net-people" posting in that newsgroup. If it has expired, you can get a copy using the instructions below (note that the name in the instructions below may change when a new version with a new date is posted, so you may need to ask for an index of the soc.net-people archive to find out the name of the most recent version).

Note that this is listed as THE last resort, to be tried even later than using a telephone number or paper mail address. Any posting to the Usenet uses the resources of the sites on the Usenet and of the networks that carry it; certainly, the total cost of transporting a Usenet message is more than the cost of a stamp or a short phone call. Since the benefit gained is to you and not to the Usenet as a whole, you should avoid posting if you possibly can.

Finding Host Names Whois

The NIC "whois" database mentioned above contains site and organization information as well as information about individuals. Organization entries in the NIC database will usually list an administrative, technical and/or zone contact person, with his/her address, to whom you can write. You can also write to "postmaster" at almost any Internet host to get in touch with someone responsible for E-mail. U. Texas Network Directory

The University of Texas publishes a network directory. Although it hasn't been updated in a few years, it still provides a useful list of many site names. It is available for anonymous ftp from several different locations, including /net.directory/1988.netbook on emx.utexas.edu. It is BIG, so you might not have room to store it locally, unless you ask someone in charge to set up some space for it. You should NOT transfer it to /tmp every time you need it, or something like that; that's a horrible waste of network bandwidth. Contact people are usually listed in the site entries in the net directory, but you might want to try "postmaster" first. This directory is superseded by the book "The user's directory of computer networks," whose bibliography information is provided in the 'References' section below. Of course, you have to pay for the book, and you can't grep dead trees, but it's probably more up-to-date than the University of Texas directory. UUCP maps

Entry Changed: Tue Jul 4 1995

The UUCP maps are posted in the comp.mail.maps newsgroup. See the posting "UUCP map for README" in that directory for more information. You can grep in the news spool or use your news reader's search facilities to search for a particular string (e.g. an organization name) in the comp.mail.maps postings. Each UUCP map entry lists the contact person for the entry. You can also search the UUCP maps by connecting to the "uumap" WAIS database on port 210 of wais.cic.net. For more information about WAIS, see above. Netinfo

You can also search UUCP maps using the University of California at Berkeley's Netinfo service (which also supports other services, such as looking up IP addresses for hosts on the Internet). You connect to it at port 117 of netinfo.berkeley.edu, e.g. on some systems, "telnet netinfo.berkeley.edu 117". The "ufind", "ufile", "uhost" and "upath" commands are used to look up information in the UUCP maps. For more information about Netinfo, connect to it and type "?". Merit Network NetMail database

Allows one to find the appropriate bitnet, internet or uucp address for a site given part of the address.

telnet hermes.merit.edu

At the "Which Host?" prompt, type netmailsites then enter any part of the address you want. nslook/nslookup and hostq programs

Some sites have programs which will give you information about a host given its name or IP address. Some such programs include nslook, nslookup, and hostq. /etc/hosts

Entry Changed: Mon Feb 15 1993

Mail routing on UNIX machines on the internet use to use a large file called /etc/hosts to validate host names. We used to advise you to examine this file to guess host names when all else fails - but that really isn't useful anymore. Use one of the above methods instead.

Creating the Internet version of an America Online address requires that you know the conversion rule. You ignore the case, remove the spaces, and add "@aol.com" to the end of the address. Thus, an America Online address "Jane Doe" becomes "janedoe@aol.com" (without the quotes, of course). Internet mail incoming to America Online is trucated at 27 kilobytes. Internet to Compuserve

Entry Changed: Sat Dec 7 1996

If someone's Compuserve ID is 77777,7777 you can send Internet mail to 77777.7777@compuserve.com (change the comma to a dot, and append the site name). Their Web directory lets you search for people by name, location, or occupation. Internet to DELPHI

Entry Changed: Sat Dec 7 1996

Delphi users can receive Internet EMail at <username>@delphi.com. Usernames are user- defined and vary from handles to real names. Their Web directory lets you search for member Web pages containing your search terms, or browse their username directory. Internet to GEnie

Entry Changed: Sat Dec 7 1996

Creating the Internet version of a GEnie address requires that you add "@genie.com" to the end of the address. Thus, a GEnie address "J.DOE3" becomes "J.DOE3@genie.com" (without the quotes, of course). There is no added cost to GEnie users (beyond normal connect-time charges) to send or receive Internet mail. GEnie addresses are case-insensitive, but you should preserve periods. Internet to Prodigy

Entry Changed: Sat Dec 7 1996

where "abcd12a" is the recipient's Prodigy user ID. We have not found an Internet-accessible directory. Internet to T-Online (Germany)

Entry Created: Wed Nov 22 1995

Since Summer 1995, T-Online (former BTX) users have access to the Internet. Use the T-Online Id of the recipient and add -000x where x is the appropriate user number, mostly 1. The T-Online Id is mostly equal to the telephone-number of the person, inculding the city prefix. To send a mail to a T-Online user in Frankfurt (city prefix: 069), with the telefon number 123456, send Internet mail to 069123456-0001@T-Online.de.

 Pассмотрим, как происходит отправка письма, а именно, что шлет твой мейлер серверу. Итак, подключившись к серверу на 25 (smtp) порт, мейлер посылает "HELLO my.domainname.com", где my.domain.name - твое доменное имя. Далее начинается отсылка письма "MAIL FROM: hax0r@domain.ru" - этой командой мейлер сообщает серверу, что автором письма является hax0r@domain.ru. Потом указывается получатель - "RCPT TO: lamer@lamehost.gov.ru". Теперь отсылается тело письма: мейлер шлет команду - "DATA", а потом само письмо. Завершается посылка письма символом ".". Вот и все. А теперь о менее приятном. Многие сервера просто не дадут тебе отправить почту таким образом, они потребуют авторизации. А найти Open Relay сервера не так легко. Самый простой выход - поставить свой собственный сервер и слать почту через него. И тогда указывай любой мыльник, хоть god@olimpus.org :).

Установление личности по адресу

  • Finger

  • Поиск в WWW

  • Поиск в Usenet

  • Поиск в E-mail Directories

  • И еще один способ ...

    Да, действительно, а зачем устанавливать личность по известному адресу электронной почты? А зачем ставят автоматический определитель номера на телефон? А зачем существет база данных, в которой по телефону можно определить имя и адрес человека? Много причин, начиная от чистого развлечения (кто не хочет поиграть в Пинкертона?) до желания выяснить, кто это с адресом someone@oxford.edu поздравляет вас каждый год с днем рожденья и признается в любви. Кстати, история не вымышленная, знакомая автора получала такие сообщения и выяснила, что посылает их ее школьная любовь, молодой человек, с которым она не виделся лет 7, и который стеснялся открыть свое имя. Продолжение было….ну, в общем, оно было. Кроме того, описывая методики такого поиска информации, автор хотел бы показать читателю, как уязвима (или неуязвима) его privacy в сети.

    Заметим сразу, что способы выяснения личности по известному адресу e-mail весьма разнообразны, причем ни один из них не гарантирует успеха. Обратная задача решается довольно тривиально: множество e-mail directories Four11, WhoWhere, позволяют найти по имени человека его адрес (если, конечно, он сам того захотел).Мы же рассмотрим задачу нетривиальную.

    Finger

    Воспользовавшись программой WS Ping32 или лучше CyberKit вы получите возможность как бы направить ваш указательный палец на любой адрес электронной почты и спросить "А это кто?". Иногда вам могут ответить. Итак, мы задаем адрес (выдуманный автором) someone@oxford.edu, получаем:

    Login name:someone In real life: John McCartney

    Directory:/usr/someone Shell: /usr/bin/csch

    Last login Fri Aug18, 1995 on ttyv3 from dialup.oxford.edu

    No mail

    No plan

    OK, someone@oxfrord.edu принадлежит John McCartney. Дело сделано, хотя очень часто вы не получите никакого результата, либо строку следующего содержания:

    Forwarding service denied

    или:

    Seems like you won't get what you are looking for;)

    Тоже самое можно сделать, не перекачивая указанные программы (хотя они и очень полезны и пригодятся не раз).

    Следует заметить, что выполнение Finger с использованием имени хоста (в данном случае oxford.edu) может не принести никакого результата, в то время как использование видоизмененного (альтернативного) имени хоста результат даст. Как узнать альтернативное имя хоста? Воспользуйтесь CyberKit , функция NS LookUp. Введите имя www.oxford.edu и посмотрите на полученный результат. Он может содержать альтернативные имена хоста, называемые aliases, ну скажем panda.oxford.edu. Попробуйте someone@panda.oxford.edu, может сработать.

    Иногда информация в ответ на finger-запрос может быть выдана только пользователю из того же домена, к которому принадлежит адрес, который вы хотите идентифицировать. Решение простое: найдите пользователя из искомого домена в Internet Relаy Chat и попросите его сделать finger запрос. Программа-клиент для IRC содержит функцию finger, так что никакой специальный софт человеку, к которому вы обратились, не потребуется.

    Поиск в WWW

    Очень просто: наберите адрес в AltaVista и нажмите Find! Можно прямо здесь:

      

    Есть вероятность, что вы либо найдете домашнюю страницу искомого пользователя, либо упоминание о нем на других страницах. Там вполне может быть имя обладателя адреса, а может и фото, если повезет.

    Поиск в Usenet

    Если человек с искомым адресом отправлял в какую-нибудь группу Usenet сообщение, то его можно разыскать по адресу. Для этого можно воспользоваться AltaVista, которая позволяет производить поиск во всех недавно отправленных в Usenet сообщениях. Заполните поле поиска искомым адресом прямо здесь (перед адресом необходимо написать from:). После нажатия кнопки Find откроется новое окно с результатами поиска:

      

    Более предпочтительным вариантом является поиск в системе DejaNews, т.к. если искомый адрес не найден среди недавних сообщений, система предлагает поискать его среди старых. Поиск также можно произвести прямо с этой страницы (from: писать не нужно, просто адрес):

      

    Поиск в E-mail Directories

    Службы, позволяющие разыскать электронный адрес человека по его имени, широко представлены в Интернете. Меж тем эти же службы иногда можно использовать для выполнения обратной задачи. Если пользователей, чьи адреса принадлежат к искомому домену, немного, то система в ответ на запрос выведет список всех таких людей, но, как правило, не более сотни и без указания части адреса, стоящей перед знаком @. Чтобы выяснить адрес целиком, придется следовать по ссылке для каждого имени, что займет много времени, если адресов много. Если же людей с таким доменом больше ста, то поиск таким способом теряет смысл. Другими словами человека из @aol.com или @netcom.com так не найдешь.

    Cуществуют также несколько служб, позволяющих искать человека по его электронному адресу, без всяких ухищрений.

    И еще один способ ...

    Cуществует еще один метод узнавания личности человека по адресу e-mail. Сначала вы узнаете mx сервер, который использует данный адрес. Для этого в nslookup нужно устновить q=mx и набрать ту часть адреса, которая находится после собачки (@). После этого программа вам выдаст некую информацию, в которой будут содержаться имена mx серверов - следует выбрать один из тех, у которого наименьшая цифра preferens. Далее нужно соединиться с помощью telnet с найденым сервером SMTP. Программа соединится с сервером, как будто она передает e-mail. Дальше вы можете использовать команду expn искомый адрес. Иногда сервер ответит на эту команду подробно - тогда вам повезло, иногда ответит we not allow this command - в таком случае остается последняя попытка - helo имя сервера (на который вы зашли). Иногда после приветствия подобные команды начинают исполняться - чаще нет (значит сервер засекречен настолько, что через него вам не удастся узнать ничего о вашем абоненте). Можно попробовать проверить остальные mx подобным методом.
