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

Hi James,
I don't know what is happened but now ssh-keygen problem is solved! I have only restart condor on node after i have seen that node remain claimed also when job is finished. Now i have error from mpi script modified by me to run intel mpirun. I go to debug it .... 
Thanks

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 ....

Hi Pierpaolo,

Is condor_master daemon running as user condor, or as user nobody?
If it is as nobody, these would seem ok, but if it's as user condor,
those permission will prevent processes owned by that user from
writing into that directory structure.

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.

Hi Piarpaolo,

I can get an error return code of 1 if the whole directory path
given to the ssh-keygen program doesn't exist, or is not writable
(permissions):

e.g.

ssh-keygen -q -f /tmp/junk/hostkey -t rsa -N ''

returns 1,

but

ssh-keygen -q -f /tmp/hostkey -t rsa -N ''

returns 0

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

Hi,
i have a problem using mpi wrapper script on my cluster (CentOS 5.3). 
Sorry for my english.
This is my cmd file:

universe = parallel
executable = mp2script
arguments = a.out
machine_count = 2
log = mpi.log.$(Process)
output = mpi.out.$(NODE).$(Process)
error = mpi.err.$(NODE).$(Process)
notification = error
should_transfer_files = yes
when_to_transfer_output = on_exit
transfer_input_files = a.out, mpd.hosts
queue

When I submit this cmd, I obtain this error file (after inserting
'set
-x' in mp2script):

++ trap sshd_cleanup 15
+++ condor_config_val CONDOR_SSHD
++ SSHD=/usr/sbin/sshd

++ /usr/bin/ssh-keygen -q -f /home/condor/local/execute/dir_3412/ tmp/ 
hostkey -t rsa -N ''
++ '[' 1 -ne 0 ']'
++ echo ssh keygenerator /usr/bin/ssh-keygen returned error 0 exiting 
++ exit -1

ssh-keygen seems not to works properly but i don't know why....

Someone can help me to solve this problem?

Best regards
Piarpaolo
