Re: Ethernet bonding with netgraph

Hello, Could someone please explain to me how to setup a channel-bond between two ethernet cards? http://people.freebsd.org/~paul/FEC/ From there, you can fetch the needed source. You have to copy it into your source tree, compile and install. After you have the ng_fec module in /modules, see

Re: For those who had problems with MPD server and win clients

2002-10-24 Thread Nikolai Saoukh
Applying patches to mpd does not fix bugs in MS software ;-) In MS software (Win XP Pro SP1 at least) there is the option 'negotiate multi-link for single link connections'. Unfortunately it can't handle it, when succesfully negotiated. One can verify it at (page to frame 82)

Re: tcp_input's header prediction and a collapsing send window

2002-10-24 Thread mark tinguely
After taking a close look at tcp_input, I think I see a senario where this could happen. Say header prediction handles ~2 GB of data without problems, then a retransmission happens. snd_wnd starts collapsing as it should. The header prediction code is correctly skipped as the snd_wnd no

2002-10-24 Thread Don Bowman
From: Kevin Stevens [mailto:Kevin_Stevens;pursued-with.net] Any suggestions for how one would start debugging this to find out where its stuck, and how? At a guess, you need to tune the state-table retention time down. If by that you mean the MSL? I've set the MSL to 5000 in this case.

Method to share kernel mbufs with a user process?

2002-10-24 Thread Dave Dolson
Until the multi-threaded kernel becomes stable... (I'm using 4.6) Is there a quick dirty way of sharing mbufs with a user process? The objective is to get the advantages of multi-processors yet avoid the syscall overhead for each packet. E.g., a netgraph node could queue mbufs in memory shared

Re: Bridging when one interface has no carrier

2002-10-24 Thread Lars Eggert
Hi, I debugged this a bit further and figured out what the problem is. The ISC dhcpd uses a bpf to listen on an interface. When a broadcast packet (e.g. DHCP request) comes in on one interface, the bridging code will correctly forward it out all the other interfaces in the cluster, and also

RE: Machine becomes non-responsive, only ^T shows it as alive under l oad: IPFW, TCP proxying

2002-10-24 Thread Don Bowman
From: Don Bowman I have an application listening on an ipfw 'fwd' rule. I'm sending ~3K new sessions per second to it. It has to turn around and issue some of these out as a proxy, in response to which some of them the destination host won't exist. For reference, the solution is
