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
match_max 100000
expect "assword"
sleep .1
send -- "tester\r"
expect {
-re "]|test|\$"
}
sleep .1
send -- "export LANG=en_US.UTF-8\r"
expect -re "]|test|\$"
sleep .1
send -- "su -\r"
expect "assword"
sleep .1
send -- "root_tester\r"
expect -re "#|assword|root|ROOT|%"
sleep .1
send -- "export LANG=en_US.UTF-8\r"
expect -re "]|root|#"
sleep .1
trap { stty rows [stty rows] columns [stty columns] \
< $spawn_out(slave,name)} WINCH
interact {
\034 exit
}
----------------------------------------------
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.
Output from simple script:

Just a note, in my /home/apmartinez/.ssh/config file I have the line:
XAuthLocation /usr/X11R6/bin/xauth
Any ideas as to why the full script isn't working?
Thanks in advance.
