[rancid] RANCID/clogin context-change FWSM/ASA

Wed Nov 18 06:51:55 UTC 2015

I found a working solution:

/usr/lib/rancid/bin/clogin -c 'terminal pager 0;changeto context admin\rchangeto context system;sh running-config\rexit'

The prompt seems not to be the problem, the problem appears at the "changeto"!
I saw, that it worked with the actual logged-in-user: "admin# changeto context admin" No timeout!
So i tried it with the actual one and DIRECTLY with a "return" (\r) behind it an change tu the system context - this works, without ";"!
The same problem later in the commands, so i type also a \r at before the "exit". Fine!

Now i can work with the script.
Thanks and greetings.
:-)

I did look at this a while ago and there was also a change required in clogin so that the expect script also looked for a wider variety prompt.
