Trying to run a script over ssh, having issues with tty assignment
Hey folks! I'm trying to run a tcpdump command that monitors for possible malicious traffic. I want to be able to run this on any of several remote boxes that I monitor which all have different capture interfaces. I've gotten the script to the point where it logs into the box and attempts to run the commands but the capif command is giving me problems.


If I'm ssh'ing into the sensor myself the same series of commands works fine. I could create a scriptfile on each of the sensors and have this script run that but there's a lot of them.

fiu-run

fiu-run(1)						      General Commands Manual							fiu-run(1)

NAME

       fiu-run - a script to launch programs using libfiu

SYNOPSIS

       fiu-run [options] program [program arguments]

DESCRIPTION

       fiu-run	is  a  script to make it easier to launch programs using libfiu(3). It can enable failure points and start libfiu's remote control
       capabilities before starting to execute the program, avoiding the need to write a special launcher to inject failures.

       It is specially useful when used to inject failures in the POSIX/libc functions, because it does not require any program modifications.

       After launching programs with fiu-run, fiu-ctrl(1) can be used to enable and disable their failure points at runtme.

       For additional documentation, go to the project's website at http://blitiri.com.ar/p/libfiu.

OPTIONS

       -c command
	      Run the given libfiu remote control command before executing the program (see below for reference).

       -x     Use the POSIX libfiu preload library, allows simulate failures in the POSIX and C standard library functions.

       -f ctrlpath
	      Enable remote control over named pipes with the given path as base name, the process id will be appended (defaults to  "$TMPDIR/fiu-
	      ctrl", or "/tmp/fiu-ctrl" if "$TMPDIR" is not set). Set to "" to disable remote control over named pipes.

       -l path
	      Path where to find the libfiu preload libraries. Defaults to the path where they were installed, so it is usually correct.

       Remote control commands are of the form "command param1=value1,param2=value2".  Valid commands are:

       'enable name=NAME'
	      Enables the NAME failure point unconditionally.

       'enable_random name=NAME,probability=P'
	      Enables the NAME failure point with a probability of P.

       All of the enable* commands can also optionally take failnum and failinfo parameters, analogous to the ones taken by the C functions.

EXAMPLES

       The  following  will  run the fortune(1) program simulating faults in read() with 5% probability (note that the -x parameter is required in
       this case to enable failure points in the POSIX and libc functions):

	      fiu-run -x -c "enable_random name=posix/io/rw/read,probability=0.05" fortune

       By running it multiple times you will see that sometimes it works, but most of the time you get different errors, resulting from the  simu-
       lated failures.

SEE ALSO

       libfiu(3), fiu-ctrl(1).

       If  you	want  to  report bugs, or have any questions or comments, just let me know at albertito@blitiri.com.ar. For more information about
