Experimental queueing

2003-06-20 Thread Trevor Talbot
I'm playing with pf/altq code for a project of mine, and some of it may be of interest to people here. The diffs are for -current only. http://homepage.mac.com/quension/pf/qexp0.diff The first diff gives pf DiffServ and ECN awareness (IP level; TCP level ECN is already present). The

synproxy client-side firewall?

2003-06-20 Thread HKSPKS
If you have a default deny firewall policy, but allow incoming synproxy'd http connections, are the packets that are generated and sent out by pf (to verify the existence of the initial syn's source IP) treated as part of the current stream on the client side of the connection? In other

Linux virtual server competition

Hi list, I'm sure anyone here knows about the linux virtual server (layer 4 load-balancer). I searched the web for an equivalent for *bsd, but found none. The only thing which looks like something like a load-balancer is the FreeBSD loadd, which requires packets to copied from kernel-space

Load Balancing and pf rdr

2003-06-20 Thread Jonathan S. Keim
Hello all, I was reading the archives from October 2002 on load-balancing with pf[1], and it seems that adding the ability to redirect to hosts from a dynamic table would make building userland health monitoring substantially easier. For example, if we have the following pf.conf: # pf.conf

PF, Queueing, Bridging, and ARP frames

2003-06-20 Thread Jeremy Evans
I'm having some problems with queueing using pf on a bridge (3.3 i386 GENERIC). I'm using priority queuing with 10 queues, the default queue being the lowest priority one. It appears as though arp request frames going through the bridge are being put into the default queue, and that it is not

I think you would not have to blow up the pf code itself too much. Simply put, take a look at the packet in ip_input.c. Look, if it should be destinated to some of your real server. Calculate the next real server to give to packet to based on some infos (connections, load, etc). Create a
