Re: GNU Parallel Bug Reports Unable to transfer multiple files when password-less SSH is not setup

[Zhi Shen]

Ole, Andreas,

We have password-less SSH setup for specific servers only.  For the ones that does not support password-less SSH, we will enter the password(s).

We are able to enter the passwords when sending a single file.

local$ ./parallel --nonall -k --bf file1 -S remote "ls -trlh"

When sending more than one file, entering the passwords does not work.

local$ ./parallel --nonall -k --bf file1 --bf file2 -S remote "ls -trlh"

We have a work-around for this, which we tar up the files before running parallel and then cleaning them afterwards.

Thanks,

zhi

Alternatively, set ControlMaster (and ControlPath) and ssh to the remote
machine(s) in a separate terminal manually before running parallel. You
don't have to enter the passwords again, then.

I have this in my ~/.ssh/config
Host *
ControlMaster auto
ControlPath ~/.ssh/address@hidden:%p

Cheers,

Andreas.
