Hey all, i am fighting with a strange behavior here - i have two systems connected via a direct crosslink wire. After booting, the connection is up and both systems can reach the other one. After a small time window the interface is down. $ dmesg |grep eth4 igb 0000:41:00.2: added PHC on eth4 igb 0000:41:00.2: eth4: (PCIe:5.0Gb/s:Width x4) igb 0000:41:00.2: eth4: PBA No: G13158-000 8021q: adding VLAN 0 to HW filter on device eth4 igb: eth4 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX igb: eth4 NIC Link is Down igb: eth4 NIC Link is Up 10...

Hi, in my lan I have two firewall, fw1 is the first and manage inte-vlan routing. Fw2 manage internet and dmz. fw1 and fw2 have an interface (eth4 for both fw2 and fw1) on the same subnet that permit to the host behind fw1 to reach internet, my problem is on fw2: eth4 is the NIC that connect fw2 and fw1, I would''t like masquerading hosts behind fw1, so to eth4 of fw2 arrive all traffic from the vlan managed by fw1, what is the bes...

Hi, I am trying to put together a hashing filter based on example provided in LARTC how-to document. I want to link two hashing filters together where first one will use 3rd octet of an IP address as hashkey and second one will use 4th octet as hash key. How do I tell mask the address so that u32 filter uses 3rd octet as hashkey? Venkatesh K _______________________________________________

...'network-bridge'' in the Xen files. The networking appears to be fine. My first DomU is the firewall (also Ubuntu 6.06). It sees the two NICs no problem, but does not see them as ''eth0'' and ''eth1''; they are ''eth3'' and ''eth4''. Networking works (the DomU can access the Internet, etc.) I am not sure why the DomU would be seeing these as ''eth3'' and ''eth4''. The "dmesg" output does not reveal any other interfaces being "allocated" Thoughts? Thanks, in ad...
