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. + diff --git a/try-from.8 b/try-from.8 new file mode 100644 index 0000000..9c62f66 --- /dev/null +++ b/try-from.8 @@ -0,0 +1,28 @@ +.TH TRY-FROM 8 "21th June 1997" Linux "Linux Programmer's Manual" +.SH NAME +try-from \- test program for the tcp_wrapper +.SH SYNOPSIS +.B try-from +.SH DESCRIPTION +The +.B try\-from +command can be called via a remote shell command to find out +if the hostname and address are properly recognized +by the +.B tcp_wrapper +library, if username lookup works, and (SysV only) if the TLI +on top of IP heuristics work.
