Re: [Fab-user] SSHException with Ubuntu 9.04

[Jeff Forcier]

Hi Ted,

Offhand that doesn't look like a config issue, especially if it's
intermittent. Are you saying that sometimes that exact command below
will work, or does it always bail out? What other commands have you
successfully run with run() or sudo(), and what other commands have
died -- or is it truly random?

What version of Fabric are you using, a git clone or 0.9b1 or what? :)

What version of Paramiko do you have installed? IIRC some older
versions of Paramiko can cause problems, you'll want 1.7.4 or newer.
(In fact, 1.7.5 came out recently, and looks like it may fix those
Python 2.6 warnings, hooray!)

Finally, it looks like you're using Python 2.6 on...OS X 10.3 Panther?
Is that accurate or is your egg path leading me astray? Don't know of
any specific issues on 10.3, just want to make sure I know what your
platform is for the record.

Sorry for the interrogation but that's tech support for you :)

Best,
Jeff
