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.
telnet through expect functions

Posted by harsh (harsh), 11 March 2005

I am using expect functions(exp_spawnv and exp_expectv) in C++ code. i was using rlogin method to connect to remote host which was working i am changing "rlogin" to "telnet" which is creating some problem. The initial banner of remote host is not coming into exp_buffer so we are not ablle to search for word "login" which is creating problems.
Can anybody help on this.

No experience of using them in C++ ... but plenty with direct calls. Have you tried running your telnet session from the expect program (without the C++) as a test?   If so, did it function correctly?

As a wild guess, have you checked VERY carefully what your remote host is sending and what you're expecting.  Something as subtle as a capital letter rather than a lower case one can be the cause of the whole thing freezing then timing out.
