Can I do it using python?? about xterm and telnet

[cmdrrickhunter@yaho.com]

I used this _EXACT_ solution(copied below) at work a month ago, to
start 20ish programs, each with different settings.  In this case I HAD
to use telnet for some of them, because they were on an embedded
machine, 4 of them used SSH(across the internet), and the rest were
local programs.  It worked flawlessly each time (every restart of the
network... which was quite often in this case).  There may be more
integrated solutions which solve the problem, but expect is rediculousy
easy to use, and is very deterministic as long as the commands work.
If the commands fail to work (such as someone deletes your program),
debugging is rather difficult, but at least you have a full dump of
everything sent by the server (because pexpect prints it all to the
screen).  Also, once the connection is open, you can call
conn.interact() and it will make the terminal interactive, just like
any other shell.
