pxssh timeout issue

[Prabakaran141]

At some situation I'm facing this error, I have added the error details below. Can somebody help me in fixing this issue?

1 2 3 4 5 6 7 8

...         s = pxssh.pxssh(timeout=5, maxread=2000000)         switch_ip = raw_input('Enter the switch ip: ')         username = raw_input('username: ')         password = getpass.getpass('password: ')         s.PROMPT = "\[.][\#]"         s.force_password = True ...

I have tired changing maxread value and timeout value, but the error still persist, I'm not sure whats happening here.

[Larz60+]

you need to capture the timeout:

1 2 3 4 5 6 7 8 9 10

try:             s = pxssh.pxssh(timeout=5, maxread=2000000)             switch_ip = raw_input('Enter the switch ip: ')             username = raw_input('username: ')             password = getpass.getpass('password: ')             s.PROMPT = "\[.][\#]"             s.force_password = True         except pxssh.ExceptionPxssh as e:             print("pxssh failed on login.")             print(e)

Not tested, but should be ok

Hi Larz60+,

Already I have the try...except block

The error I added is a captured one

[Larz60+]

Ok, so why are you holding out? in order to give advise, need the full picture
Show enough code to determine what is wrong

[Prabakaran141]

I have added the entire code.
This code is for removing some configurations in Switch, Please go through this and the error which I attached already and Give some view on it.
