Thanks Will,

Thanks.

Ok,
I was able to test this simplified script and it works just fine when I
run it, the output is below. The problem arises when I try to execute
the full script which is:
$ cat expect_full.test
#!/usr/local/bin/expect -f
set timeout -1
spawn -noecho ssh -X -vvv -p 22 -l test -o StrictHostKeyChecking=no \
-o UserKnownHostsFile=/dev/null -o GSSAPIAuthentication=no 192.168.0.10

I get brought back to what looks to be a password prompt but then when i
try to type a password it actually prints whatever I type right on the
screen. Hitting enter does nothing and the session just sits there
indefinitely.
Just a bit more information, I am connecting from an OpenBSD 4.8 system
to a RedHat 5.5 system.
The output when executing the full script is also below.

expect and spawn
Hi All,
I am trying to use openbsd as my workstation here at work but one of the
tools we use, creates an expect script and it's not working at all. The
developer of the tool uses linux primarily so he's not sure except to
tell me that the expect in openbsd doesn't know spawn which I looked and
the expect man page is loaded with stuff about spawn.
The script I try to run is this:
# cat 227254.test
#!/usr/local/bin/expect -f
set timeout -1
spawn -noecho ssh -X -vvv -p 22 -o StrictHostKeyChecking=no -o \
UserKnownHostsFile=/dev/null -o GSSAPIAuthentication=no \
r...@192.168.0.10
interact {
\034 exit
}
Executing this from the command line returns the following:
# sh -x 227254.test
+ set timeout -1
+ spawn -noecho ssh -X -vvv -p 22 -o StrictHostKeyChecking=no -o
UserKnownHostsFile=/dev/null -o GSSAPIAuthentication=no
r...@192.168.0.10
227254.test[3]: spawn: not found
+ interact {
227254.test[4]: interact: not found
+ 034 exit
227254.test[5]: 034: not found
227254.test[6]: syntax error: `}' unexpected
Is the format of his expect script all wrong or??
Thanks,
Aaron Martinez

This might be a silly question but have you installed expect from the
ports? Also expect depends on tl and tcl which will be installed which
are installed along with expect.

Hi Paul,
I do have expect installed but not via ports, I just used the packages.
Thanks.

Re: expect and spawn
Thus said Aaron Martinez on Tue, 09 Nov 2010 09:48:15 CST:
# sh -x 227254.test
Why are you telling sh to interpret an expect script? Why not try:
$ expect 227254.text
227254.test[3]: spawn: not found
+ interact {
227254.test[4]: interact: not found
+ 034 exit
227254.test[5]: 034: not found
227254.test[6]: syntax error: `}' unexpected
These errors are all produced by sh. sh is trying to execute the
commands in 227254.test and is it any wonder that it doesn't recognize
the words spawn, interact, 034, and says there is a syntax error?
Is the format of his expect script all wrong or??
No, you are using the wrong interpreter.
