What's wrong with your cluster?

[infinitevalence]

its something with the DHCP, my nodes are downloading their OS fine off the TFTP server but they are not able to connect after being assigned an adress fomr the DHCP server.

Have you entered a default gateway?

[infinitevalence]

NA

[kenc51]

try this command

route add -net default gw 192.168.2.1 dev eth0

change the IP to what ever is your gateway/router.....

Yeah its not that... its something in the DHCP config info on the DHCP server. Sadly my roommate admins that server so i have to get his ass to fix it

[kenc51]

The end of that .config file..

# Use your gateway IP, if required
option routers 192.168.1.1;
# Use your DNS IP, if required
option domain-name-servers 192.168.1.1;
option domain-name "mydomain.com";
# Use your slave hostname
option host-name "slave21";

Instead of using your gateway(192.168.1.1) to resolve DNS, enter your ISP's primary DNS server IP.
It's worth a try!
After that I wouldn't have a clue......

yeah its something with the way its attaching to the NFS server for RW, and DHCP i think.... not anything to do with the external gateway, i dont even need internet connections on these as they all load and download from the master NFS server.
