Hi everyone,

I have the exact same problem with two of my servers running on SCO 5.0.5.

The first one is part of a tiny network (about 6 or 7 'clients') so I don't think the number of TCP connections is the reason. Thanks to your previous posts, we are about to install a packet sniffer on the network.

The problem is that I'm not really a network expert (and my native language is french) so I'm a bit lost in all the information the sniffer will give to me. What am I supposed to search for ? Gratuitous ARP Requests ? I've read that those requests are sent to check for double IP, is it true ?

Thanks in advance

edit : I'm trying to install tcpdump on my server. When I try to launch it, I have en error message : "no cards available to use in /dev/mdi". And when I try to give him the interface I want, it says "Can't open device - Device busy". Do I need to install a second card on the server ?
