I have been testing my front ends for about a month now and had finally got to a point where I can deploy them. In testing the FE and BE were on the same network but in production they are on separate subnets.
When I boot the FE they get to talking to the back end and stops with the unable to talk to backend error.
The FE's are on a 192.168.1.0 network. The Backend is on a 192.168.20.0 network. DHCP and Routing with Linux/Windows hosts works fine between the 2 networks. When I telnet into the FE and run route I only get 1 line - see below -
Code: Select all
Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
It appears that the DHCP IP config is being rewritten and losing the default gateway.
I am running PXE Boot with the ram-minimyth-0.21.0-62 image.
I have had a poke around the udhcpc script as was pointed out in a previous post but not being a scripting guru I can't figure out which part of the script is killing the IP config.
Any help greatly appreciated.
