tcl/expect stdout redirected to file stops (possibly due to a "@" in exp_send)

I have a shell script to run an tcl/expect script where I want to redirect the stdout and stderr to external files:

Code:

./expect_script.tcl >> stdout.log 2>> stderr.log

The tcl/expect script starts to run and starts to redirect stdout to the log correctly until I get to the following line in my tcl/expect script - were the stdout stops being redirected to the log file:

Code:

exp_send -s "no snmp-server community C00r-H3@l view cutdown RO 10\r"

The expect script runs completely without error (except for the logging issue) - so I really don't know what could be the problem as to why it just stops redirecting the output.

Well, if you suspect '@' it might be a good idea to remove it and see what happens.

Have you tried

Code:

set exp_internal 1

. At least it shows what goes back and forth over the connection, sometime that is quite unexpected (no pun intended) and undiscovered because your matching rules prevent this to be printed. But there is a lot of output there and it might be worth looking at it.

BTW, I have a bit of the opposite problem, do you know a solution for this? http://www.linuxquestions.org/questi...stdout-737549/
