Full Discussion: Trying to run a script over ssh, having issues with tty assignment
Top Forums Shell Programming and Scripting Trying to run a script over ssh, having issues with tty assignment Post 302271768 by JASI on Saturday 27th of December 2008 11:20:11 PM
Old 12-28-2008
I believe that whats happening is that the script is attempting to run capif on the box that I'm running the script on instead of running capif on the remote box that I'm ssh'ing into.

As I said, if I put those commands in a script and run them on the remote box after having ssh'd into the box then it works just fine.

While playing around with it I found that using ssh -t -t gets rid of the
/whilemenu: line 24: capif: command not found
Pseudo-terminal will not be allocated because stdin is not a terminal.
mesg: ttyname

error and replaces it with an error:
tcgetattr: Inappropriate ioctl for device

Again, if I create the script on the remote box and either ssh to the box manually and run it or ssh via the scrip and call the 2nd script on the remote box it works as intended.

So whatever the problem is it's something to do with interactivity of ssh from what I can tell.

ttt

ttt(1)									net								    ttt(1)

NAME

       ttt - Tele Traffic Tapper - a standalone program for local, real-time, graphical traffic-monitoring.

SYNTAX

       ttt [-interface device] [-interval ms] [-dumpfile file [-speed N]] [-yscale (K|M|n)]

DESCRIPTION

       ttt is the standalone traffic monitor program in the ttt program suite. It displays trafic-data of a local interface.

       To run ttt, you must be "root" on most systems since only root is allowed to access the network filter device.

       The  ttt program suite is yet another descendant of tcpdump but it is capable of real-time, graphical, local and remote traffic-monitoring.
       It won't replace tcpdump, rather, it helps you find out what to look into with tcpdump.

OPTIONS

       -interface device
	      specifies the interface for packet capture. If not specified, the default interface is chosen.

       -interval ms
	      Sets the interval in Milliseconds. If omitted, a interval of 1000 msec. is used as default.

       -dumpfile file [-speed N]
	      use a dumpfile (produced by "tcpdump -w") as input. The speed option specifies the acceleration factor of the replay speed.

       -yscale ('K'|'M'|n)
	      change the scale of y-axis. 'K' and 'M' represent 1000 and 1000000 respectively.

EXAMPLES

       To run this program the standard way type:

	      ttt

       To listen only on interface eth0:

	      ttt -interface eth0
