Expect/Tcl help?

earnstaf · #1 (**permalink**) 07-25-2007

Does anyone know of an expect/tcl forum that is as helpful as this one is for shell scripting?

Or if anyone has any expect knowledge, can you please provide some guidance on how to write to a local error log based on output from a ssh session?
I have something like this:

Code:

foreach host $hostlist {
spawn ssh -oPort=22 -oStrictHostKeyChecking=no -oCheckHostIP=no $USER@$host-sdp
expect {
  "Connection closed by remote host" { puts "$host is down.  Please try again later."; continue }
  "password:" { send "$PASSPH\r" }

If they first condition is matched and it sends the message about the host being down, I'd like to output the error to an errorlog.

How do I a.) initialize the log file and b.) write to it in the case of an error?

Thanks for any help. Again, I realize this isn't the forum for expect/tcl, but it has been very helpful to me in the past in learning shell scripting, so hopefully someone can provide some insight or at least point me in the right direction.
