This is verging on seriously off-topic, but I don't know where else to ask.
I am beginning to work with various queue disciplines. Per the Advanced Routing HOWTO, I've downloaded the htb qdisc and patched the kernel. I have all that working. I need to set up three levels of service: 1) interactive ssh (9.6kbs) 2) VOIP 96kbs 3) everything else I have 128kbs to work with, so I want to set it up where 1 and 2 have guaranteed bandwith when they need it, otherwise others can borrow from it. I've read in the Advanced Routing HOWTO that "SSH sets TOS to 'Minimize Delay', unless it is doing scp, in which case it sets 'Maximize Throughput'." Does anyone know if this is true? If so, I may have missed it in patch-o-matic, but is there a way I can fwmark based on TOS? I want to fwmark packets based on ports/ip for the qdisc; this should be straightforward. My next question is more complicated: The whole thing runs via vpn, so I have to mark the vpn packets to minimize delay, otherwise I lose VOIP. But that gives "bulk" transfers like email high priority if they're in the same VPN. Should I set up two vpn channels then? Or one channel for each service? Does anyone have any experience with qdisc they'd like to share? Thanks, --Yan -- Future fighter pilots: Me: Akari, WHAT are you DOING?
