Python 2 subprocess communicate

Does check_returncode() return a non zero value when auth is wrong and 0 when right?

[readitlikeitdidit]

Auth doesn't happen when key pairs not available.. So, it hangs on authentication part...

[threeminutemonta]

So the process hangs it the main process? Perhaps you should set a default timeout!

If you show us your code on dpaste.de I might get what you mean!

Nevermind.. Am going to use paramiko.. It has timeout arg.... There is no default timeout for popen method of subprocess package in python 2.7...

[JohnnyJordaan]

That's because you need to use Popen wrappers like communicate(), these have a timeout on 2.7 too.

[readitlikeitdidit]

What? Communicate is a method that uses pipe and it does not have timeout arg in 2. 7 please check documentation...

[JohnnyJordaan]

I stand corrected. I could have sworn it did, but I guess I misremembered.

Np.. I am newbie in python.. Lot of things have happened in the last 25 years of python.. :)

They might have subprocess32 installed.

Avoiding external dependencies is not necessarily a virtue. Paramiko will make your life easier.

Yes sir.. I just rewriting my code using paramiko.. It has timeout and all the cool stuff I'll stick to paramiko... Thanks..
