Mod Comment In message #18 in this thread, I asked you to open a new thread to discuss this new topic. You ignored that request and instead sent a private message and an additional message in this thread basically repeating the same information.

I repeat, if you have a different problem (from the once described in the first message in this thread) where you also need help, open a new thread with a clear description of what you are trying to do, what code you're using, what you input looks like, what output you are trying to produce from that input, and a clear description of what processing should be performed to transform your input into the desired output.

safe_finger

SAFE_FINGER(8)						     Linux Programmer's Manual						    SAFE_FINGER(8)

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.
