Measuring time of a telnet connect

[Fabian Lanze]

Hi!

I want to realize the following: I want to measure the time it takes to
build up a telnet connection to a known host (ip/port). I tried to use
subprocess.Popen to build the telnet connection and then to catch the
"Trying to connect..." and "Connection established" output. But this
didn't work - both had always the same timestamp (time.time()) - i think
that's due to some buffers.

Has anyone an idea how to solve this?

Tanks in advance..
