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.

SYNOPSIS DESCRIPTION
tryfrom
This program identifies the end-point details related to a connection. This program must be called via a remote shell command as shown
below. It is used to find out if the hostname and the address are properly recognized, and also if the username lookup works properly.
prints the following output when it is invoked:
The information related to the client describes how the remote host recognizes the client in terms of address, name and user name. The
information related to the server gives the remote host's details.
See hosts_access(5) manual page for more information on expressions.
sffinger
This is a wrapper program to the finger(1) client which offers better protection against the possible damage from data sent by the remote
server. This command accepts all the options supported by finger(1).
It is recommended to use this program in the implementation of traps in the access control language of and See hosts_access(5) man page for
more information on setting traps.
This program restricts each line length to 128 bytes and total response to a maximum of 100000 bytes. uses 60 seconds time-out value in
getting the response from the remote host's server.
