Can someone verify that using fw as a filter in iproute2-2.6.11-050330 is broken. Doesn''t seem to work in any case and I saw an earlier post that would lead me to believe this is the case. If so does anyone have a temporary fix? Thanks, Troy

...o all, hoping someone can help me out here. I cannot get dummy interfaces on a new Cent8 build to persist across reboots.

...to vblade on _one_ host and i have tried that mentioned "clever juggling of network devices" on my system, but i didn`t succedd. some coraid employee recommended trying linux-bridging - so i created two dummy interfaces (module dummy.ko), created a bridge "aoe-bridge" and added dummy0 and dummy1 to that bridge. then i "connected" AoE-driver to dummy0 and vblade server process to dummy1 and would have expected that this should work. unfortunately, it failed to work and from what it seems it wasn`t a problem with AoE or vblade but with the bridge, because i couldn`t se...

Hello all, I have a linux machine with a SIP server (Asterisk) and 2 WAN interfaces (NATed) configured to do load balancing. I experienced problems with the SIP/RTP protocols and load balancing, because when initiating a call to an external SIP Host, a new RTP flow starts from the server to the Host, that sometimes uses another default route (due to the nexthop configuration). As i have two

Whilst ip= command is documented to support dns0:dns1 options as arguments 7 and 8, the -d parser in ipconfig does not.
