Connection testing with Perl
If you've never used the Perl Sockets module for basic connection testing, you might be surprised at how easily you can craft a very useful script. I find my version of a Perl "listen" script to be as useful as a cable tester!

Either way you look at it Microsoft Data Center management did not follow standards or best practices in this failure. In which case it makes me wonder more about the outsourcing of corporate data much less personal data.

nc
Nice script, but i find myself using netcat for this kind of thing:remote machine: 'nc -lp 9999'
local machine: 'telent remote 9999'
you should see a connection establish and then you will be able to type into the session and whatever you type will appear on the remote netcat session. you could also pipe a file into nc and it will be echoed in your telnet session:
'nc -lp 999 < /etc/motd'
This works on any machine with netcat installed (which I think should be default)
I hope this will be useful to you at some point sandra.
Especially useful on Solaris and the like
Yes, nc or netcat is a powerful utility which can do the same and much more and will be my first choice on Linux systems. However, nc is not available by default on Solaris and if you have constraints which prevent you from installing nc (for example, some crazy company policy), then this script is very handy. Thanks Sandra.
