Connect to solaris from cygwin through pexpec, getting error "read_nonblocking()."

[sanju.d1231]

Hi,

I have written a small code to connect to solaris machine from cygwin...but this code is giving some error. please see the code below..i am expect some solution of this error.. Thanks in advance

import os, pexpect, time

FirstTime_Ssh='Are you sure you want to continue connecting (yes/no)?'

def ConnectUnix():
connect=pexpect.spawn('ssh sanju@hostname')
#time.sleep(20)
i=connect.expect([FirstTime_Ssh,'.*password:',pexpect.EOF],timeout=100)
print i
if i==0:
print "yes"
connect.sendline('yes')
i=connect.expect([FirstTime_Ssh,'.*password:',pexpect.EOF],timeout=100)
elif i==1:
print "give the password"
time.sleep(20)
connect.sendline('sanju')
time.sleep(20)
print connect.expect(pexpect.EOF,timeout=120)
elif i==2:
print "got the key or connection timeout"
pass
print connect.before

ConnectUnix()

This is the error section:

Then put some code tags around your actual code.
Python scope rules rely on indentation, and your post without any is broken beyond help.

All I can tell is that your expect strings never get found. So you would be better to figure out how to do this on the command line, and then replicate those actions using pexpect (since pexpect basically spoofs you performing the same commands (sendline) and waiting for certain responses (expect))

As you can see from the pexpect failure, the last 100 characters of output from your command were the following:

buffer (last 100 chars): Generic January 2005
Sun Microsystems Inc. SunOS 5.10 Generic January 2005

Thanks a lot Jim for your comments.

jim My expect string gets found, because of you see the i, its value is 1 which means expect string is able to found the .*password string..

problem starts when i send the password from the sendline..
after sendline its not sending any response.

I don;t know why it is happening because ideally it should return some thing.. :(

When you send your password do you hit 'Enter' ? Add \n after your password to see if that helps.
