Here is a puzzle. I have a network with several servers. It''s a mess. It''s a /24 and pieces and servers are all over the place inside this /24 block, on both sides of the firewall. For example, the router at 1.2.3.1 is outside the firewall and many of the servers at 1.2.3.nnn/24 are behind the firewall. (Obviously, 1.2.3.nnn is a fudged network.) eth0 points outward to

Hi everybody. Do you know about any way to read the TCP cwnd value (congestion window) on Linux? I have read that on Linux it is not possible to enable a socket option (to read to cwnd using the program trpt). Any way to read the cwnd would be good for me. thanks Antonio

Hi all. I would need to use a single physical interface on a Linux box to manage two different IP addresses (belonging to two separate logical subnets) with two different MAC address. (I need to emulate te presence of two separate physical interfaceses for a PC on the same LAN, at layer 2 and layer 3). Is it possible to use the linux ethernet bridging code and two tap interfaces for this

Hi! By iptables I set marking (-j MARK) just before -j IMQ. There are only three marks. Exectly all of them are ditected to 1:20 Why I see 3 pkts in default 1:30?

Woops - my fat fingers hit the send key before I could put in a subject a minute ago. Hello - I am using kernel 2.4.27 and running into behavior I don''t know how to explain. I have 2 relevant interfaces. eth0 is external, eth1 is internal. My internal LAN is 10.10.10.0/24. My External range is 1.2.3.0/27 (dummied up). I have an H.323 videoconference device inside my internal

Hello list, I''m having problems with HTB on a machine. I noticed that after a while the machine seems off-line after i start the htb script. After some debugging i realised the problem stays in the arp packets send by the machine, which are delayed or dropped. Because of that i had to remove the default class. Is there a way to match arp packets ? because i want to add them to the class

hello, i have a 5500 iPaq with familiar 0.8.2 on it and i don''t know how to install a traffic shaper tool on it. I installed iproute2 package i found on familiar site and for that i have the tc and ip commands, but when trying to add a qdisc, as a dummy example, i get the next answer: > tc qdisc add dev wlan0 root cbq bandwidth 100Mbit avpkt 100 RTNETLINK answers: Invalid argument

Hi Couple months ago I started to have a strange problem with HTB. My setup is Fedora Core 2 + Pentium 2 233 + 128 MB of ram and its serving as a router. For some time since going to kernel 2.6 my HTB QoS Stalls for couple seconds, every couple minutes. If the connection load is bigger the stalling is more frequent and takes longer. I isolated the problem to be with HTB (CBQ works fine). The

Hi all, I need to provide shell hosting for about 40 users, and few days ago I found the wondershaper script, so Im trying to know if this script could help me to improve interactive ssh/telnet connections. Wondershaper could help me or its only efective on OUTGOINGS requests? Ok, any comment and feedback will be welcome. Sorry for my bad english and THANKS in advance.

In 2.4 kernels, there was a [bp]fifo that could be implemented with ''tc add'', but in 2.6 kernels, I find no way to create either of these fifos. I am able to increase txqueuelen. What I desire is a larger number of backlogged packetes before drops occur. How can the output buffer size be increased for HTB? -- gypsy

Hi, Can any one please guide how do I handle the SIP phone-context URI parameter.

Stephen, This REALLY needs to be fixed in the code; tc should reject as a syntax error any "add filter" command that does not include a "prio" parameter. It also needs to be documented. === From LARTC mailing list === > Dear list, > After much code crunching and beating my head against the wall > (literally), I discovered the faulty code. Thanks mostly to

Hi I have been playing with tc. I''m using htb and sfq. I tried to setup shaping of every ip address within a /20. I found that there must be an upper limit of about 2096 on the number of rules (classes, qdiscs or filters). I was testing a /20 which gives 4096 classes, qdiscs and filters. I''m using hashkey to optimize processing of frames. When executing the script below - it

Can''t get proxy arp with arp -s <IPaddr> <MACaddr> pub to work with a 2.4 kernel. I see some evidence in the archive that this was broken in the 2.0.x timeframe and never fixed. Anyone know for sure if it''s broken or working ? (I''m attempting to route a few addresses into a routed network, from the ethernet side of a DSL router that has a /29 public

Hello alltogether, I''m new to the list, so please excuse any violations of listiquette... I didn''t have to much to do with linux based firewalling and routing for quite a time and found that proxy-arp changed in between... As I struggled with it I found that the Advanced routing... howto wasn''t to helpfull. Especially the documentation seems to be rather vice versa to

Hello all, I need a very simple routing protocol for VPN redundancy. We have several sites and each site has a Linux router and two IPCops each with an ADSL connection to the internet using different ISP''s. I have configured VPN''s between all of the sites for each IPcop on ispA and the same for the IPCops on ispB. This way, if one of the ISP fails, I change the route on the
