Lose Connectivity

I have a triple-boot machine with the following OS's:
1) RHEL 5.4
2) Vista SP2
3) RHEL 5.3

I am set up with static IP addresses all within the same domain and netmask using /etc/host, /etc/host.equiv and /root/.rhosts.

When I switch from Linux 5.4 to Linux 5.3, I can no longer ping the server until I ssh into it, then they see each other.

Any suggestions why?

Hi there,

As I can understand you have a machine configured with triple boot. When you restart you machine and login to RHEL 5.3 clients are no longer able to ping it until you ssh into it.

You are using static IP across all OS (triple boot OS).


1. Is your RHEL 5.3 machine is able to ping the host from where you are trying to ping it.
2. If yes, then appears to be client side problem. It means that client still remember that static IP on RHEL 5.4 went down.
3. Did you try ipconfig /flushdns on client machines and then gave ping a try?
4. Did you try tracepath/tracert when you client machine is unable to ping RHEL 5.3 machine?
