expect: ssh & screen parameters
|
|
| nickforpresident@gmail.com 2007-05-21, 7:10 pm |
| I'm using a little expect script to log into a router via SSH, and run
a command (via cron). This router detects the SSH client's screen
size, and only sends screenfulls of data at a time, followed by:
--More-- (q) quit (u) pageup (/) search (n) repeat
at the bottom of each screen. How can I run expect and make it use ssh
in VT100 or similar mode?
Any ideas or pointers in the right direction are greatly appreciated.

Not too sure about your problem. But I guess you probably have
problems
seeing the expected text as you need to hit "u" to see it. If that's
the case, you can always add a line to detect it in your expect loop.
E.G.
expect {
"login name: " {
...
}
"assword: " {
...
}
"--More-- (q) quit (u) pageup" {
send u\r
continue
}
}

If I run the command logged into the shell, I never see the the --
More-- option. This started happening when I added the expect script
to run from cron. Also, when running from cron it only gives me 1 line
of output before that --More-- thing happens. I guess the router is
detecting the screen size of the connecting machine and outputting
accordingly. Any suggestions on how to "fool" the remote router?
Thanks

For cisco routers, a:
terminal length 0
should disable the --More-- prompt alltogether. In that case you don't
need to handle the 'More' case anymore.

Unfortunately, for more reasons than this, this isn't a cisco box.
When cron executes the expect script, the remote device only thinks I
have one line to work with. But when I run it manually from the shell
(bash), it gives me all the space I need... Is there an environment
variable maybe that's controlling this? I'm trying to script expect to
login to the router, run a couple commands, and output the results to
a file. Thanks for your suggestions so far.

This is a solvable problem.
Decompose it. Perhaps you have already; are you saying that
the Expect script does everything you want, with a long screen,
OUTside cron, but when you cron-ify the script, you see the
only-a-line-at-a-time symptom? *That* is easy to solve ...
