Re: [Condor-users] Problem with sshd.sh, ssh-keygen and Parallel Universe

["Burnash, James" <jburnash@xxxxxxxxxx>]

The thing is ... what user is condor running as ... and does that user have permissions to navigate down to the tmp directory.

For example, what are the permissions on /home/condor/local/execute/dir_3412?

Also, sometimes errors like this pop up because filesystems are full - probably something you've already checked, but if not it can cause weird problems ...

Hi James,

thanks but also changing permission to the dir 'tmp' in this way:

drwxrwxrwx 2 nobody nobody   4096 Sep 16 17:07 tmp

it does not work ....
