Finding E-Mail Addresses on the Internet

Finding E-Mail Addresses on the Internet:

The following are some of the ways to find out someone's computer userid on the Internet:

I- At Columbia University (within Cunix), a search can done by using "lookup" command. With the lookup command "the address, the phone number, and the department" of a user can be found.

At the cunix $ prompt type:

lookup person's name/userid

Ex: lookup john smith or lookup js4

II- Another way of finding someone's userid is using "finger" command. To use this command, however, you need to know the node, and the "finger" command has to be supported by the site you are searching. Here is how it works:
At the $ prompt type:

finger lastname/firstname/or/fullname@machinename.domain

Ex: finger John Smith@pitt.edu

III- Searching can also be done through gopher. "gopher://gopher.cc.columbia.edu:71/11/phones" can be used to retrieve information for "Students, Staff, and Faculty" within Columbia University and all over the world.

IV- Go in to a mail program (e. g. pine):

1) Send a mail to: mail-server@rtfm.mit.edu

2) In the subject: do not write anything

3) In the message body, type: send usenet-addresses/name
Example:

1) mail to: mail-server@rtfm.mit.edu

2) subject:

3) the message body: send usenet-addresses/John Smith

After this message is sent, you will receive a list of addresses which contains the word John and/or Smith. There are two other addresses which can be used in the same way:

1- mail-server@pit-manager.mit.edu

2- mail-server@Bloom-picayune.mit.edu

V. People's e-mail addresses can also be found in the following way:

At the $ prompt type telnet bruno.cs.colorado.edu

Then when asked for a login, type "netfind" (without quotes)

VI- The Internet Information Center offers several ways to find someone's e-mail address.

To use this servis, at the $ prompt type telnet to ds.internic.net.

Ex: $ telnet ds.internic.net
