Pssh, Timeout killed by signal 9

Question

I use PSSHto run commands on other machines to implement parallel computeusing IPyParallel, but I ran into a problem, my command

pssh -P -h ip.txt -i ipengine --file=~/parallel/test/ipcontroller-engine.json

And after a while it returned:

[1] 11:54:41 [FAILURE] 192.168.0.112 Timed out, Killed by signal 9

I think something is wrong with PSSH, but I do not know how to solve it.

Answer 1

After googling, I found that the command psshwill only last 60 seconds if you do not enter an option -t. So, to solve this problem, I type the command

pssh -P -h ip.txt -t 100000000 -i ipengine --file=~/parallel/test/ipcontroller-engine.json

And the team will be killed in 100000000 seconds

Answer 2

-t timeout
--timeout timeout
Make connections time out after the given number of seconds. With a value of 0, pssh will not timeout any connections.
