I have been trying to optimise my ADSL connections for VOIP. Funny things were happening - for example increasing the ping packet size by 50% had no effect, but then adding one byte had a major effect. It took me a while to figure out that I was seeing the effects of the fixed ATM cell size. This is probably obvious to some of you. For the rest: ADSL uses ATM as its transport. An ATM

Hi I''m using wondershaper like script. But noticed imperfect scheduling. By googling, I found some patches that takes the aal5 atm overhead in the scheduling algorithms. http://www.adsl-optimizer.dk/ADSL-optimizer/ Before trying it, has anyone tried these patches? they apply on 2.4.29 kernel and 2.6.9 TC. I use centos4 with a 2.6 kernel, so I can''t try these easily. Thanks

Greetings routing folks, I want to use the netmask 255.255.255.255 to insulate (not quite isolate) machines on a shared subnet from each other. This works just fine on win XP, but Linux iproute will not acccept the gateway address in one step -- neither on the command line nor via DHCP: Here''s the interface, set up with a netmask of /32: # ip addr ... 2: eth0:

Dear List. I try to build multipath connection w/ load balance to internet with two different gateway; My system is RH-8.0 with iproute-2.4.7-7.90.1.rpm and Kernel-2.4.26 (patching with Julian A. patch),and follow guide from http://www.linuxvirtualserver.org/~julian/nano.txt, The problem is; when i try to connect to Internet form gateway machine it;s success , but only one interface is

Hi, I live in a rural community where adsl and cable is not widely available. I correctly have an option of using adsl or cable at my location. Ten miles away my friends apartment building has no option of cable or adsl. I set-up a wireless link between my friends apartment building and my house. It works great for him and me and the adsl company doesn''t care because they

Hi, I have implemented QOS classifiers using TC with HTB. The classification is working. I would like to know whether there is some tool which will help me in monitoring the bandwidth share of the various classes. Thanks, Vinod C

Hi I have just moved my firewall from a 2.6 debian machine to a 2.4.30 openwrt (linksys wrt54gs) box. I orginially had this working with 2 isp, 1 cable 1 adsl and dyndns. Now when i have moved to 2.4.30 I am having problems. Everything else is working fine except when I DNAT packets from the firewall to an internal address, ie my web browser is inside so I DNAT from the external IP to the

Hello lartc! I have strange problem setting load balancing over 4 interfaces. Something won''t accept more than 3 interfaces, While setting: ip route add default scope global \ nexthop via 0.0.0.0 dev pvc0 weight 1 \ nexthop via 0.0.0.0 dev pvc1 weight 1 \ nexthop via 0.0.0.0 dev pvc2 weight 1 It''s ok: ip r l default nexthop dev pvc0

Dear List, I am wanting to perform some traffic shaping as the subject of this email suggests. What I am wanting to do is this; I would like to have traffic shaping performed on the following protocols: HTTP, RDP, GRE, PPTP, SIP and IAX. Obviously I would like to have highest priority set for voice packets so much so that the general http traffic does not impede on the voice packets. I

I have read the thread at http://mailman.ds9a.nl/pipermail/lartc/2006q1/018287.html and still don''t know how to fix this problem. It appears alot of work has gone into it but the HOWTO is so out of date it doesn''t even begin to addresses this method. So here are my questions 1. what is the current state of these patches? are they in a specific version? do i have to patch myself?

how to use iproute/iptables to balance by packet OUTBOUND traffic between 2 PPP (pptp cable modem and pppoe adsl modem) links to the same ISP . also by using the fact that the ISP dosen''t filter source IP address - meaning i can use either PPP''s link assigned IP address as the source IP in the ip header.., it works for both devices.., what i want to achive is : when uploading a

I am working on my Diploma Thesis on Computer Science Engineering. The main idea behind of my work is to make it possible to have a Linux box combining multiple ISP/network connections together providing a single connection with an aggregated bandwith. I have been surfing the Internet and I haven''t found anything like that running on Linux. I would like to implement it using iproute 2

Hello List, We are having a NAS here with 4 TB (sic!) disc space and a samba server as a file server (or better: as one of the file servers). Now the vendor tells us: with samba you can't share more than 2 TB of that. This is not enough. Is that a restriction of Samba, Linux or of the vendor's system? I never encountered this restriction... Please help! -- Mit freundlichen Gr??en

Hello List, I am (unsuccessfully) trying to automatically get a valid kerberos ticket for my linux box. I have - in a test environment: - a windows 2000 server with Active directory and DNS properly set up. - a suse linux 9.0 router with samba3.0.2.rc.1 and heimdal 0.6.-67. - I am able to join the domain and get a valid ticket through kinit, if I enter the Administrator's password or the

Hey folks, I stumbled across the Mastershaper project ( http://www.mastershaper.org/ ) but I have a little problem: I wanted to shape the traffic coming from the router itself aswell as coming from the LAN behind the router, for that task I need IMQ, but with IMQ iptables-(layer7)-matching is not possible. Now I''ve talked with the programmer and he said the following: >The problem is

Hi, Thanks for the reply. Thats where the problem starts. If I set ppp0 as the default gw the internet doesnt work anymore. This is how im doing it... route del default route add default gw 217.32.81.74 dev ppp0 if I put it back to ppp1... route del default route add default gw 217.32.68.73 dev ppp1 It works fine again. Whats up with that? Cheers, Chris ----- Original Message

Hi all... How do i set U32 to filter a port range, instead of a single port? In normal use: source port 80 we use: "... match ip sport 80 0xffff ..." - I know that is something about the 0xffff parameter.... I need to filter ports 1 ~ 1024 to a higher priority class... i tried with IPTABLES MARK and TC FW, but it''s not working.... (...) # iptables -t mangle -A PREROUTING -p

Hi all, i am using iptables (1.2.8) + iproute on Slackware 8.0 (i386) working fine, marking packet based in destination port and network and selecting the appropriate route with this marks (i have two links, a 256Kb frame relay and a 512Kb ADSL). Now i change the machine for a Sun Enterprise 250 (Sparc64 with Debian 3.0r1) and iptables works fine (the packets are marked) but iproute

Hi, I have the following situation: 1 gateway box with 2 WAN interfaces (eth1 and eth2). 1 LAN interface eth0 default gateway is eth2 I want to route all traffic with destination protocol tcp 22 (ssh) NOT over the default gateway eth2 but force them to find it''s route over eth1. All other traffic must go the normal way over eth2. Is this possible with tc or an other tool? --
