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

[Pierpaolo Minelli <pierpaolo.minelli@xxxxxxxxxxxxxx>]

Hi James,
the whole directory path given to the ssh-keygen program exist and  
these are permissions in the directory:

-rwxr-xr-x 1 nobody nobody 499183 Sep 16 15:54 a.out
-rwx------ 1 nobody nobody     50 Sep 16 15:57 chirp.config
-rwxr-xr-x 1 nobody nobody   1745 Sep 16 15:54 condor_exec.exe
-rw-r--r-- 1 nobody nobody     12 Sep 16 15:54 mpd.hosts
-rw-r--r-- 1 nobody nobody    697 Sep 16 15:57 mpi.err.0.0
-rw-r--r-- 1 nobody nobody     36 Sep 16 15:57 mpi.out.0.0
drwxr-xr-x 2 nobody nobody   4096 Sep 16 15:57 tmp

Directory tmp seems to have right permissions.
