I will try the tcpdump, I've been able
to do stupid stuff with the fence_sanbox2 python script (repeat
sequences of issue/expect; increase the python delaybeforesend
value) to get it to work most of the time, but I don't believe the
script code is wrong, there's something else going on, perhaps the
switch is in a funny state. Now, how would I detect *that*!
Thanks,

You might want to grab a tcpdump of the connection.
Perhaps you'll be able to see a bit more of the conversation.

I can manually telnet into the FC switch and execute the
appropriate
commands to enable/disable ports. But the fence_sanbox2 script
will not.
The fence_sanbox2 code has not changed, however python has
been upgraded
from 2.6.6-29 to 2.6.6-36.
Has anyone else seen this? Know of a fix? Am I doing/not doing
something
stupid? I seem to recall running this command before during
setup and it
worked just fine then.
Thanks for any help!
