Using the finger service w/telnet on a remote server
The finger command is implemented on Unix systems. It will tell you
information about a specific user that has an account on the system.
The information given by the finger command is the data placed in a
file ".plan" by the user and also the status of their email and when
and where they last logged in.
Log into the remote server on port 79 with telnet.
To find information about a specific user of the system:
Type the name of the user you would like to find information about and
hit [Enter]. The system will automatically disconnect you when the data
transfer is complete.
Example:
user
To find information about a user on a different system:
Type the name of the user you would like to find information about
followed by the @ symbol and then the name of the system in which the
user is a member. This is the direct equivalent of an email address.
Note that many systems will not forward your request.
Example:
user@foreign.system.com [Enter]
To retrieve a list of all users currently logged on to a system:
Hit [Enter].
Example:
[Enter]
Note:
To record the results of your query, in Windows, select to record a log file
before hitting the [Enter] key. After you are disconnected, select OK and
stop the log file.
