telnetlib problems

[vercingetorix52 at yahoo.com]

Thanks for the reply. I've replaced the call to read_very_eager() with
read_until() and enabled debugging messages.  My script now looks like
this...

#############################
import telnetlib

tn = telnetlib.Telnet('192.168.100.11')

tn.set_debuglevel(9)

tn.read_until('login: ', 5)

tn.write('user\n')

tn.read_until('Password: ', 5)

tn.write('password\n')

tn.read_until('bash-2.05$ ', 5)

tn.write('ls\n')

print tn.read_until('bash-2.05$ ', 5)
#############################

Each call to read_until() returns a valid string except for the second
one, i.e.,
tn.read_until('Password: ', 5) returns a null string.

Here's the program output with debugging enabled...

Login incorrect



login:
#############################
It looks like it's sending the password before receiving the password
prompt.

Any ideas?
