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.

ssh-argv0

SSH-ARGV0(1)                                                BSD General Commands Manual                                               SSH-ARGV0(1)

NAME

     ssh-argv0 -- replaces the old ssh command-name as hostname handling

SYNOPSIS

     hostname | user@hostname [-l login_name] [command]

     hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
     [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]

DESCRIPTION

     ssh-argv0 replaces the old ssh command-name as hostname handling.  If you link to this script with a hostname then executing the link is
     equivalent to having executed ssh with that hostname as an argument.  All other arguments are passed to ssh and will be processed normally.

OPTIONS

     See ssh(1).

FILES

     See ssh(1).
