Hello. My PC have a two ethernet interfaces. Both are connected to one network (/24) by two ports of Catalyst. The eth0 have IP-address 1.1.1.1 and eth1 - 1.1.1.2 I need to see ALL packets from and to 1.1.1.1 address in eth0, also ALL packets from|to 1.1.1.2 in eth1. Now, many packets from|to 1.1.1.2 I can see by "tcpdump -i eth0" (not in eth1). Do you know special setting in network configuration of SuSE_9.3 to separate a traffic by interfaces? Thank you. Oss.

i don't need calculate a traffic, i want to separate packets by ipaddress to own interfaces Oss

You can configure the routing tables to do that.

I'm not sure your suggestion really works. Because regular IP network devices, like routers, don't allow config to have two IP addresses in the same subnet, like his case, to be set on two physically different interfaces. Because the device can't determine which interface to send packets destined to another subnet, or even in the same subnet. If it allows, I can't imagine how the routing table looks like. Toshi

This is a switch configuration issue. The switch is not echoing the packets to all ports instead of to the specific port with the mac address assigned to the port. I have not used Cisco switches in many years so I can't tell you the exact thing to fix. If this was Foundry I could tell ya. Brad Dameron SeaTab Software www.seatab.com
