Well, if you happen to be the unix administrator, you could front-end the finger command with a little script. Just tested out OK for me. I renamed /bin/finger to /bin/fingerACTUAL, then installed my script to /bin/finger:

Code:
#/bin/sh
# finger front-end script
expr "$*" : ".*jboothe.*" > /dev/null &&
  echo `date;whoami` >> /tmp/finger.log
fingerACTUAL "$*"
exit $?

You need to allow for "finger user1 user2 user3". If your username appears in the parameter list, it will append to a log file. It does not delimit the search string in any way, so if you are looking for jdoe, you would also get jdoe2 etc.

Passing the parameters as $@ might be more appropriate??? It exits with the status code that fingerACTUAL returns.

There may be issues that I am not aware of, so I must say use at your own risk.

NAME
safe_finger - finger client wrapper that protects against nasty stuff from finger servers SYNOPSIS
safe_finger [finger_options] DESCRIPTION
The safe_finger command protects against nasty stuff from finger servers. Use this program for automatic reverse finger probes from the tcp_wrapper (tcpd) , not the raw finger command. The safe_finger command makes sure that the finger client is not run with root privileges. It also runs the finger client with a defined PATH environment. safe_finger will also protect you from problems caused by the output of some finger servers. The problem: some programs may react to stuff in the first column. Other programs may get upset by thrash anywhere on a line. File systems may fill up as the finger server keeps sending data. Text editors may bomb out on extremely long lines. The finger server may take forever because it is somehow wedged. safe_finger takes care of all this badness. SEE ALSO
