pssh, Time out, killed by signal 9

Question

I am using PSSH to run command on other machines to implementing parallel compute using IPyParallel, but I encountered a problem, my command is

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 there is something wrong with PSSH, but I don't know how to solve it.

Answer 1

After googling, I found pssh command will only lasted 60 seconds if you not input -t option. So, to solve this, I type the command

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

And the command will be killed after 100000000 seconds

Thanks @Nicolas Thery and @Setzer22, instead of setting an arbitrarily large value, you can set -t 0 to disable the timeout functionality.

Answer 2

Set pssh to have a timeout of 0 to disable the default 60 second timeout. -t 0

pssh -P -t 0 -h host_file <COMMAND>

The top answer suggests a really long timeout, when you can just disable it.

Answer 3

-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.
