[Condor-users] Condor,Fedora core installation problem

[prashanth palakollu <palakoll@xxxxxxxxx>]

Hi,

I am a linux newbie and trying to install condor for my academic project.

I have been stuck with this problem for quite a while now and after trying to find out the cause for it,I have given up.

I installed condor 6.6.10 on fedora core 4 which is running on vmware workstation 5.0 on my laptop.

I have two copies(central manager and working nodes) of fedora core 4 running on windows(host) operating system and I installed condor on both.

I can ping and ssh both the central manager and working node from each other and they seem to be communicating well.

 

These are the steps I followed for installing condor  on master node(192.168.60.128) ----

 cd /usr/local/condor 6.6.10

./condor_configure --install --type=manager  --owner=condor

 

Then I set the condor_config environment variable to /usr/local/condor 6.6.10/etc/condor_config

I made the following changes to  condor_config.local file

START ,PREEMPT,SUSPEND,VACATE variables are set to true

NETWORK_INTERFACE = 192.168.60.128

 

Also i made changes to condor_config file

MEMORY = 512

RESERVED_MEMORY =40

RESERVED_SWAP=5

 

Then i start the master daemon and do ps aux | egrep condor_.I can see the required daemons running.

I check the log files for error and everything is fine,there are no errors

./condor_status shows  me the central manager as available.

 

Now while installing condor on the worker node on the other fedora core 4  guest os ( 192.168.60.129 ),I follow the same steps ,

except while configuring the worker node,i use the command

 

./condor_configure --install --type=submit,execute --central-manger=192.168.60.128  --owner=condor

 

and remaining are the same steps.The startd,schedd and master daemons start properly.

But when I do ./condor_status.I get the following error message

 

 

CEDAR:6001:Failed to connect to <192.168.60.128:9618>
Error: Couldn't contact the condor_collector on 192.168.60.128

Extra Info: the condor_collector is a process that runs on the central
manager of your Condor pool and collects the status of all the machines
and jobs in the Condor pool. The condor_collector might not be running, it
might be refusing to communicate with you, there might be a network problem,
or there may be some other problem. Check with your system administrator to
fix this problem.
If you are the system administrator, check that the condor_collector is
running on 192.168.60.128, check the HOSTALLOW configuration in your
condor_config, and check the MasterLog and CollectorLog files in your
log directory for possible clues as to why the condor_collector is not
responding. Also see the Troubleshooting section of the manual.
 

 

Here are the log files on the working node are shown below
