[LARTC] multipath routing
Hi, I am tring to us ip route to load balance between two interfaces. ip route add equalize 10.200.1.0/24 nexthop via 10.200.0.2 dev neta nexthop via 10.200.0.2 dev neta2 Where neta and neta2 are gre tunnels. Testing show that packets travel in a single sided manner. Do I need to use the multipath (IP_ROUTE_MULTIPATH_CACHED) module? thx jason___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

What about incomming packets? how can you be sure that interractive traffic gets to you from the internet first when you download something? Priorize control packets, too. (ACK, SYN and SYN ACK).

[LARTC] Explenation of WRR parameters
Guys Oppologies for the cross post. I've been scouring the docs coming with the wrr patches and for the life of me I can't figure out why there are 8 parameters for each class. weight1, min1, decr1, incr1, weight2, min2, decr2, incr2 According to the docs these parameters are handled the same way, but looking at the example scripts there are different values for these. I had a look at the formulas, and have gotten my own set of reasonable values, based on the calculations, but do I place the same values in param1 & param2?

Is the location of the fileserver on the side of the TS server or on the side of the clients? The files are in the file server, with stands right next to the TS (connected by gigabit Ethernet). My problem is to make connections from my office to TS with maximum priority. There's some other traffic in the 1Mbit link. TS port should have maxixum priority and flow. ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
[LARTC] No Nat problem
Hello... I have the following problem: The usual way for a linux router to manage connections between 2 or more internet providers and an internal network is to SNAT the internal network into the (usually 1) external ip address that the provider has given us. My problem is that i dont wish to do SNAT (anymore) because my provider has given my a unique internet ip address for each pc so that my the internet address and local are identical. My SNAT configuration worked perfectly. I had two routing tables 1)Main 231.245.21.0/27 dev eth2 scope link 192.168.1.0/24 dev eth0 scope link 192.168.2.0/24 dev eth1 scope link default via 192.168.1.1 dev eth0 2)Policy 231.245.21.0/27 dev eth2 scope link 192.168.1.0/24 dev eth0 scope link 192.168.2.0/24 dev eth1 scope link default via 231.245.21.1 dev eth2 Where 192.168.2.0 is my internal network, 231.245.21.0 the network of Provider 1 and 192.168.1.0 the network of Provider 2.It all worked (almost) flawlessly. Certain Ports were going out from eth2 while all the other from eth0. One would say that with the internet ips i would have to make the following change: (Asuming that pc's at lan have 231.245.21.4-62 from now on) 1)Main 231.245.21.0/27 dev eth2 scope link 231.245.21.0/27 dev eth0 scope link 192.168.1.0/24 dev eth1 scope link default via 192.168.1.1 dev eth2 and 2)Policy 231.245.21.0/27 dev eth2 scope link 231.245.21.0/27 dev eth0 scope link 192.168.1.0/24 dev eth1 scope link default via 231.245.21.1 dev eth2 But alas, when i tried to do that it was not accepted: "RTNETLINK : File exists" <--- exit output I tried to do it with the route command and it was accepted only for main table but look what was happening. If i had the first declaration of the subnet in eth2 I could only communicate with the gateway 1 (231.245.21.1) while if it was eth0 in the first declaration I couldn' t communicate with the gw but only with lan. Then I tried another way. Instead of declaring the same network I declared a static route only with the gateway in eth2. Thus : 1)Main 231.245.21.1 dev eth2 scope link 231.245.21.0/27 dev eth0 scope link 192.168.1.0/24 dev eth1 scope link default via 192.168.1.1 dev eth1 2)Policy 231.245.21.1 dev eth2 scope link 231.245.21.0/27 dev eth0 scope link 192.168.1.0/24 dev eth1 scope link default via 231.245.21.1 dev eth2 And in that way i managed into the point that i could communicate from my linux router with both sides. I mean Provider 1 and internal network. I could also communicate from my local lan with provider 2. But the real problem is that i cannot communicate with Provider 1 from my local lan. Is this the right way to accomplish that and i am missing something or is it the tottally wrong way to do it. Someone plz help. Thank you in advance ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

[LARTC] Help regarding TBF and CBQ
Hello Please give advice in selecting suitable QoS Solution for our device. It contains one WAN port and a LAN port(4 port switch). The WAN will be connected to an ADSL modem(so we don`t know the bandwidth in advance for the WAN and depends on the ADSL connection taken). We need to give highest priority to the Voice and control the WAN bandwidth to 2Mbps. I tried with the TBF by giving 500kbps for voice and 1.5Mbps for other traffic(I`m assuming that a user takes atmost 2Mbps line). But the maximum throughput i`m getting for the data is 1.15 only. Even if create only one TBF class with full 2 Mbps rate). I need to simulate different WAN bandwidth speeds like 64kbps, 128kbps, 256kbps..etc, How to do simulate this?. What is the maximum bandwidth that a TBF can control?What is the suitable solution for providing a QoS to our device?Does CBQ helps in my case?Thanks in Advance.Regards,Suresh Babu. ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
[LARTC] Bug in ip -6?
Hi, this appeared on Red Hat bugzilla and I'm not sure if customer presumption is correct `ip -6 route add 10::a120/124 via 10::a111` returns RTNETLINK answers : invalid argument His expected result is that route table to subnet 10::a120/124 should be added I know RFC3587 described prefix 001b is the unicast global address range assigned by IANA, and all other unicast address rage is 'unassigned'. But 'unassigned' does not mean illegal. It's only administrative purpose. Implementation should not get such restriction. Is he correct? Should this be fixed? -- Radek Vokál <[EMAIL PROTECTED]> signature.asc Description: This is a digitally signed message part ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
