Hello everyone,

I'm getting 'unknown cipher':


Are you using the latest version of paramiko (1.7.6)?

No. Silly me. I have upgraded to 1.7.6 and it works. Thanks, James!

Performance-wise:

time cssh.py -y /tmp/meddir -i goodlin -p p -q ; sleep 5; time cssh4.py -y /tmp/meddir -i goodlin -p p -q

real    0m43.995s
user    0m20.062s
sys     0m21.497s


real    0m39.163s
user    0m10.684s
sys     0m21.902s


So the CPU usage is apparently halved, although the sending time has been reduced only slightly.

By doubling the number of allowed sending threads I was able to get higher reduction in sending time:

real    0m32.553s
user    0m10.224s
sys     0m20.732s

top still shows 90%+ CPU usage though.


Regards,
mk
