For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
How to redirect send result back to Linux box

Posted by Kan (Kan), 16 November 2005
I've prepared the following script on a Linux machine. The purpose is:
1. Automatically login to a Nortel BLN router.
2. Ping to 2 remote PC to confirm the WAN connectivity where the 2 PC are located.
3. Ping result to be pipe back to a file in the Linux box.


The problem I face is that when i try to redirect the ping to result.log, the log file is not redirected to my source LINUX mch. How to workaround this?


#!/usr/bin/expect
set hostname blnRouteIP
set username RouterLoginName
set password RouterLoginPassword
spawn telnet $hostname
sleep 10
expect "Login: "
send "$usernamer"
expect "Password:"
send "$passwordr"
send "r"
send "ping remotePC1 >result.log\r"
send "ping remotePC2 >>result.log\r"

I would use an expect command to capture the ping results and then open the file and write to it (from expect_out(buffer))

Graham,

Thanks. I got it as what you've suggested.

set ret [open result.txt w]
puts $ret $expect_out(buffer)
