Use this +program for automatic reverse finger probes from the +.B tcp_wrapper +.B (tcpd) +, not the raw finger command. The +.B 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. +.B 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. +.B safe_finger +takes care of all this badness. +.SH SEE ALSO +.BR hosts_access (5), +.BR hosts_options (5), +.BR tcpd (8) +.SH AUTHOR +Wietse Venema, Eindhoven University of Technology, The Netherlands. + |
