Re: [Condor-users] unable to chmod condor_exec.exe to ensure execute bit is set

[Joaquin Monedero <jadeade@xxxxxxxxx>]

Hi again

After some time expended here, I got a file list from one of the working directories created for executing jobs, this is what I found:

./dir_12029:

total 6392

-rwxr-xr-x 1 www-data www-data 6449123 2011-04-27 21:18 condor_exec.exe

-rw-r--r-- 1 www-data www-data       0 2011-04-27 21:21 _condor_stderr

-rw-r--r-- 1 www-data www-data       0 2011-04-27 21:21 _condor_stdout

-rw-r--r-- 1 www-data www-data       0 2011-04-27 21:18 input.txt

-rw-r--r-- 1 www-data www-data   74938 2011-04-27 21:18 Prueba0.png

-rw-r--r-- 1 www-data www-data   12531 2011-04-27 21:18 PruebaKmedias0.png

The output is similar to the previous mail, as it complains about chmodding the condor_exec.exec, but it has executing rights. 

Could someone hint me about what's going wrong here?

Thanks again in advance

Hi all

I recently installed Condor 7.2.4 in a ubuntu-server machine and I am able to submit jobs to the queue with success using "condor" user

My problem arises when I try to launch the jobs from the www-data user thru a php portal I am developing, getting this result in the starter log:

When I submit the job localy, it works like a charm, but when I try to launch it from the web server, it stays held.

I checked the rights in the /var/lib/condor directory: 

all files inside it are owned by condor:condor and www-data is a condor member so creating a new directory should become owned by www-data

I tried to create a directory manually and chmod +x a file inside that directory, logged with www-data user and it went ok

I know that this is related to user privilegies, as I am able to execute a job using the condor user, but I think I am missing something. 

Could someone show me the light?

Thanks in advance
