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 ?

we try to disable some devices after checking sniffer. but still we got same problem. after we put the server2 behind firewall. it solve our proglem. if you dont have firewall, may be you can adsl router to put in another segment since NATting is there. i didn't try this. remove devices one by one in your small netwrok & try also.

thanks
