Hi Ken,
Is there anything you did to ubuntu to get it working ?
Like changing the iptables config etc?

I have added the entries in the /etc/services file. I still have no luck.
Regards,
Jeevan

I have my SGE 6.9/6.10 running on Ubuntu 6.10 so I'm going to assume
that 6.06 is the same.

Did you make sure to add port 536 and 537 to your /etc/services?  I
usually do this by appending to the /etc/services:

sudo echo sge_qmaster 536/tcp >> /etc/services ; sudo echo sge_execd >>
/etc/services
