James,
I've not used pexpect, but I've done this on a Cisco switch. I found
using
time.sleep and read_until of the telnet class to be helpful.
10 tn = telnetlib.Telnet('<IP>')
11 #tn.set_debuglevel(9)
12 tn.read_until('Username: \xff', 5)
13 time.sleep(10)
14 tn.write('<name>\n')
15 tn.read_until('\r\nPassword: ', 5)
16 #time.sleep(2)
17 tn.write('<password>\n')
18 tn.read_until('#', 5)
19 tn.write('term len 0 \n')
20 tn.read_until('#', 5)
21 tn.write('show version | i restarted\n')
22 RouterStartupTimestamp = tn.read_until('#', 2)
23 tn.read_until('#', 2)
24 tn.write('show call history voice last 100\n')
HTH,
Steve

Folks,
Does anyone here have experience with pexpect? I'm trying to write a
pexpect script which will log into a network device, gather
statistics, and then dump the raw output into a file (or a string so
that I can manipulate it).
I'm not having much luck. Because the connection is telnet I was able
to use wireshark (a sniffer) to see the traffic between my computer
(which is running the pexpect script) and the network device.
Everything seems to go find until I "expect" the network device's
prompt and it just hangs. Eventually pexpect throws an exception and
times out.
I'd be happy to share some code when I get to the computer I've been
testing on. :) In the time being, has anyone seen a problem like this
before?
Thanks!
