Discussion related to cado-nfs

Hello,

I am trying to run a factorization with CADO-NFS on several machines, but it is not able to start the client on the second machine. Running CADO-NFS only on localhost works, my SSH config seems to be good and from what I know I followed the README instructions fine.

The command I have run:

./factor.sh 1264140330139699975151910140167392338710257567267977216954497 -h localhost,192.168.0.113

And the error it outputs when it tries to connect to the other machine (CADO-NFS would still start to factor after with only localhost):

Warning:Command: Process with PID 17969 finished with return code 1
Warning:Client Launcher: Starting client on host 192.168.0.113 failed.

Any idea what could be causing this? Thanks!
