You should check your arp tables manually (use the arp command). (Proper MAC addresses are more important w/ switches than hubs.) Do the status lights on the switch showing speed and duplex match the settings on the machines?
Also look at the error statistics on the router. (use ifconfig and nestat -s.) I had a mean problem like this before. I gave up and ended up throwing $250 of new network gear and $150 of new computer at the problem & it went away. *shrug* -Paul -- Nothing is more admirable than the fortitude with which millionaires tolerate the disadvantages of their wealth. -- Nero Wolfe _______________________________________________ Siglinux mailing list [EMAIL PROTECTED] http://www.utacm.org/mailman/listinfo/siglinux
