Greetings List''ers :-) Have been playing around with QoS, and have a problem, and some questions... Oh yeah, Debian Woody, 2.4.19, 512/128(pppoe). Problem : kernel oops''s (sadly, unlogged - though I have a display on the router, so could transpose the oops if need be...). Using either version of WonderShaper (CBQ), I get a kernel oops - it seems to take a little longer with the older version, but mebbe that''s co-inkydink... I manually entered the script from the lartc howto, and that seemed to be okay (tested for about five mins so far, then tried WS1.0, which oops''ed in less than 3...). I haven''t gotten as far as any link testing yet, but things ''feel'' different when the shapers are up... I''m using the Debian PPPoE package at present, but have built support into the new (QoS-enabled) kernel, and will no doubt switch to that (does anyone have any comments about the value of such a move?). Question : I have a Billion aDSL modem/router/etc. It has a web interface and all manner of other features. This stuff (particualrly the interface) are normally sucked through the ethernet (or usb, but we don''t touch that...) connection to the host. However, I put the modem into bridged mode so I could use PPPoE/shaping/netfilter, etc on the Linux router, which entails *not* assigning an address to the NIC. Of course, this stops me from being able to access the modem''s web interface. I guess it''s hardly that important, given the setup, but it would still be nice to be able to at least get to it in case it''s ever necessary (for a quick test-bench reconfig and back, perhaps...). Everything still seems to work when the interface *does* have an IP, though - is it okay to have an address on this NIC? Could that be what''s choking tc (probably not, as it still oops''es the kernel with no address on it...). The router in question has three legs - one going to the ''secure'' local network, one going to the DSL ''modem'', and one (two transparently bridged NICS) going to the DMZ, in case any of that matters. -- Cheers, Mattt icq : 117539757 Network and Tech Dood, www : above.nq4u.net aboveNetworks. mattt@above.nq4u.net jabber: mattt@jabber.expressnet.net.au What''s got four legs and an arm?

Small update - I just transposed the Wondershaper from the howto (that I thought was okay before) into a script - it lasted about 1min :-/ Unfortunately, I forgot to take down the oops message before rebooting the box...

Alrighty... I seem to have gotten to the bottom of the oops dilemnas... I was attaching the qdiscs to ppp0 - I''ve now (for the last 15-odd minutes) got them attached to eth3 (the interface the DSL device is attached to) and all seems well (although there''s not enough traffic right now to see how it''s working...). So that just leaves my other question... To re-iterate, I have a Billion modem - these little guys are rather feature-rich, and said features are configured via a web interface. I''ve disabled all the routing, etc in the device, and set it to bridge mode, so I can use PPPoE on the Linux router to which it''s attached (for shaping and fw''ing). Owing to this, I am bringing up the interface without an IP. This means I now, for instance, can''t easily connect to it from a workstation and, say, upload a new firmware... There are other ways to go about it anyways (like attaching an IP to eth3 on the router before I need to do such stuff to the Billion), but it would be a lot handier to be able to connect anytime (there are also some good line, etc, diags in the interface) without having to play around. So, my question - it all seems to work (the DSL connection, routing, etc) when the interface *has* an IP, so it it important to *not* have one? Will this react badly with QoS, etc (having said it worked, there was no shaping running at the time)?
