cluster.getGroomServer not returning what expected

Hello there,

I have a cluster of 2 machines and successfully run a Hama application  
on it. The problem is, though, that the number of groomservers  
returned from cluster.getGroomServers() is 1, so the number of tasks  
launched is not the maximum. I ssh to the other machine and all the  
daemons are running.

I also cant open the BSP Administration site because I access the  
computers remotely.

Is there something that I should check?

Thanks

I found the problem! Iptables was messing around and just had to turn it 
off. Thanks for answering!

Any log detail (in $HAMA_HOME/logs)? Maybe others can help check if
something doesn't function correctly.
