This is related to a post that I posted on:
Basically, I have two machines, one of them is a Solaris 8 / E450 and the other is Solaris 7 / x86, on the same DMZ. They work perfectly as independant machines, but when I tried to communicated from one to the other, nothing worked.
I asked my network admin to open the wall between them (because that is what he told me - there was a wall), and after he did, I still got the same problem.
After worrying for two months just trying to find a solution, I finally realized that the ARP cache is empty, therefore ping is not working, and anything else afterwards.
So when I run arp -a I get nothing....
There seems to be a problem in this DMZ that neither the network admin nor I can solve...
Anyway to get around it?
