Hi all,

I am trying to use a very simple expect script to automate entering one or two details into a console connection of a solaris machine so that I can do a boot net - install.

If I run the console connection script manually myself, it connects fine and when I hit enter, I am on the machine and can log in etc.

Problem is, when I spawn this exact same command from within expect, the connection seems to work but when I hit enter, nothing

Code:

spawn /console/conn.sh machinename
sleep 15
expect "Connected to"
send ""
expect "telnet>"
send "send break\r\r"
expect "ok"

What might be different about spawn, than running script from the command line.

You don't need double \r\r statement, one carriage return is OK, also, set the timeout to indefinite with : set timeout -1
Your machine may be experiencing slow responses, so rule that out. You can also try autoexpect too that comes with the expect installation.

Sysgate is right on. A couple things I'd do would be too add a debug option to the script...

Code:

if {[lsearch -exact $argv "-debug"] >= 0} {exp_internal 1 ; log_user 1}

..and instead of sending whitespace, send a newline.
