I just installed rh6.0 and I have problems configuring the 2 3c509 ethernet cards. Just for now, I'm using the ip-addresses 10.100.66.57 and 10.100.66.58 with submask 255.255.252.0.
pinging to both addresses works. (to 127.0.0.1 also). But pinging to a computer on the local network works not.
With ifconfig, i can only see eth0 and lo, not eth1. When I disable one of the cards, using netconf, pinging from the other computer works, but when I ping from the linuxbox to the other computer, ping receives the packets twice!! pinging to the two addresses 57 and 58 works fine. (no double receives).
When disabling eth0 with netconf, ifconfig shows eth1 and lo, as expected.
Any Idea's? Please comments only, I will decide hwo's comment is worth the points.
