All

I want to telnet bunch of mx servers from expect script just to check the mailserver program used from their banner (if exist) from the expect script like this :

Quote:

#!/usr/bin/expect -d

mxcount=`wc -l mxfile`
count=1
mxs=$( awk 'NR == '$count'' mxfile )
var=$(expect -c"
set timeout 5
spawn telnet $mxs 25 ---> the problems lies here and the rest
set timeout 10
expect "220*"
set timeout 10
send "helo just-test.org\n"
set timeout 10
expect "250*"
send "quit\n"
exit
")
while [ "$count" -le $mxcount ]
do
echo "$var"
let "count += 1"
done

mxfile contain the mailservers hostname I want to check separated by line.
And the script not work. I'm newbie pretended to be expert :-)

Please help.

Thanks.

you're using bash like conventions in an expect script, which i'd assume have not been mimicked by tcl here. what i do is make an expect script to do ONE job, and wrap it in bash, sometimes just a one liner...

for i in $(echo mysmtplist); do ./myexpect.exp $i; done

and let that sort the looping out for you.

Thanks for the pointer

I modified the script , read the expect man page , and this the new code

Code:

#!/usr/bin/expect --

set hostname "[lindex $argv 0]"
set timeout 5
spawn telnet $hostname 25
set timeout 10
expect "220*"
set timeout 10
send "helo just-test.org\n"
set timeout 10
expect "250*"
send "quit\n"
exit

Works as Expected !!!

TIA
