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.
expect_out(buffer) not giving output to local m/c

Posted by dibya.jyoti (dibya.jyoti), 7 September 2007
I am using expect_out(buffer) to redirect the output of the last command to local m/c. But I am not getting the output locally. I just did "apt-get install expect " . 3 days back on the same machine I used it and it worked. today I did again reinstalled , but it is not working now.
Here is the code which I am having ::

# Set the DISPLAY environment variable (as a test)
set env(DISPLAY) chilli:0
set timeout 30
spawn ssh -p 222 ipcs@
# Not absolutely necessary, but good to keep the spawn_id for later
set telnet $spawn_id
# Case insensitive, just in case..
expect -nocase "Password:"
send  "SIPera_123\r"
# My telnetd insisted on an uppercase P. This works bothways
# Match the prompt (contains a $)
#expect -re {\$}
expect -nocase "TMobile"
send "sudo su\r"
expect -nocase "TMobile"
# Get the environment variables
send "cat /proc/meminfo\r"
expect -nocase "TMobile"
## To send output to a local Machine
set abc1 $expect_out(buffer)
puts "The value of meminfo is $abc1 \n I think this "

Please help me out. I am not able move further without doing this.

If it worked three days ago but not now, the obvious question is "what has changed"?   If you cxan't work it our easily, run the ssh session manually and compare what it does to the script.
