Thanks for confirming this, both of you. I also note that Pat McNerthney just (as in <10 minutes ago) actually investigated this and put a nice, detailed comment on Robey's Paramiko Github page outlining what's going on:
http://github.com/robey/paramiko/commit/f573017a1d56c0ef9fdb08598bf4a43f40c01952 It's unfortunate that 1.7.4 is no longer available on PyPI either; if Robey isn't able to push out a 1.7.6 or 1.7.5.1 soon I can't think of much else to do for new users other than to direct them to the Paramiko site to download a .tgz of 1.7.4. In the meantime, hopefully it's obvious to anyone reading this that they should hold off on upgrading to Paramiko 1.7.5 until this is resolved :) -Jeff On Fri, Aug 14, 2009 at 7:24 PM, Ted Carroll<ted.a.carr...@gmail.com> wrote: > I had a chance to confirm this. paramiko 1.7.5 is broken and paramiko 1.7.4 > works. > > Thanks, > > Ted C. > On Aug 14, 2009, at 9:06 AM, Wes Winham wrote: > >> We had this same issue and we narrowed it down to paramiko 1.7.5 >> We were getting exceptions like: >> >>> Traceback (most recent call last): >>> >>> File "/home/christian/.virtualenvs/pstat_dev/src/fabric/fabric/main.py", >>> line 454, in main >>> >>> commands[name](*args, **kwargs) >>> >>> File >>> "/home/christian/work_devel/policystat/pstat/pstat_deploy/configure.py", >>> line 201, in deploy >>> >>> _push_source() >>> >>> File >>> "/home/christian/work_devel/policystat/pstat/pstat_deploy/utils.py", line >>> 117, in _push_source >>> >>> run('ln -s /var/www/%(pstat_url)s_%(timestamp)s /var/www/%(pstat_url)s' >>> % env) >>> >>> File >>> "/home/christian/.virtualenvs/pstat_dev/src/fabric/fabric/network.py", line >>> 371, in host_prompting_wrapper >>> >>> return func(*args, **kwargs) >>> >>> File >>> "/home/christian/.virtualenvs/pstat_dev/src/fabric/fabric/operations.py", >>> line 413, in run >>> >>> channel.exec_command(real_command) >>> >>> File >>> "/home/christian/.virtualenvs/pstat_dev/lib/python2.5/site-packages/paramiko/channel.py", >>> line 212, in exec_command >>> >>> self._wait_for_event() >>> >>> File >>> "/home/christian/.virtualenvs/pstat_dev/lib/python2.5/site-packages/paramiko/channel.py", >>> line 1077, in _wait_for_event >>> >>> raise e >>> >>> paramiko.SSHException: Channel closed. >> >> >> They would occur absolutely randomly (usually between the 5th and 25th >> run() or sudo() call for some reason), but I always got that exception >> before the script finished (a successful run has about 60 sudo/run >> calls).
