Hi all, As I read into the forum, NATting (SNAT) is expensive, using iptables to translate IP sucks the performance of the system. I just want to know if IProute2 can handle NATting and if it handels NATting can it performed faster than iptables? thanks, Wennie

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.

Hello, we are using HTB for dividing 15 Mb/s upload rate to 1022 classes (rate 14 kb/s, ceil 15 Mb/s), but sometimes ksoftirqd_CPU0 uses the most of the CPU-time (over 90% CPU load is casual in such situation). This situation occurs several times a week and takes minutes or one hour and during that time it has enormous packet loss. Reboot of the machine usually solves this problem. Because

Ok, the story is this, I''m running an Unreal Tournament 2004 server. It''s running on a system that has two external NICs that are connected to different ISPs. I would like players to be able to connect to the server from either link. My default gateway goes through NIC1. For traffic through NIC2 to work I simply added an extra routing table and rule. The extra routing table has

Is any way to detect changed MAC adresses? Someone taught change MACs peoples in my network and I have problems. E.g. Two computers working on one MAC, and one IP (static ARP and DHCP). WinXP is screaming some message... that two computers or more have the same IP. How can I find out who''s changed MAC?

Hello Everybody, I have configured a Linux box that does traffic shaping. Its working wonderfully fine, just as expected...Now i want to measure the bandwidth consumed by each of my hosts....But I dont want SNMP to run on all the hosts[as required by MRTG] I used iptraf on my linux box, but it only measures the bandwidth on interface basis only.... I tried installing traffic-vis, its not working

Hello, I''m looking how (if) can I solve the following problem using HTB and iproute2: I need to assing the same bandwidth limit to every client, but the problem is that clients will be random - i.e. I know niether number of clients no IP or MAC addresses. If anybody knows FreeBSD''s ipfw2 - I''m looking for something like "ipfw pipe 150 config mask dst-ip 0xffffffff

what is the limit on the arp cache entires ?! Does someone have very big LANs with linux-routers ? How big ? (i mean flat L2 network, not segmented) I want to know how much can my net can scale ? thanx _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

...e 128kbit ceil 128kbit tc filter add dev eth0 parent 1: protocol ip prio 1 u32 \match ip dst $ipaddress classid 1:$index but it does not work good. then I tried to find better solution in maillist. there are some solutions there. but not appropriate to us as they required patching kernel like esfq,routehat,wrr. is there any suggestion.

Hello there, Can someone please explain why do one neeed IMQ ? I can already shape incoming traffic on my nat router by creating qdiscs on LAN-side interface. I have done some tests, whith simple bandwidth limmiting, and it works. I''ve read just about all the stuff on www.linuximq.net ... but couldn''t make myself an ideea on why would someone need IMQ for ingress policing ...

I''m looking for a program that will replace the automatic ARP table population by the Linux kernel. The daemon should fix the MAC <-> IP entry from the IP of the first packet with that MAC received.

Hi, A majority of our work inolves ftp to my clients'' side over our slow connection. Now we need to allocate a greater b/w for this protocol. Is there anyway I can do it using lartc easily?

Hi, How can I set equal bandwidth of 512kbit downlink and 256kbit uplink for every single IP address of 254 IP addresses I have in my LAN? Regards, ro0ot

Hello, I have a problem with the latency of the packets passing a Linux router, and I thought perhaps you could put some light on it. It''s quite simple. I have one ADSL connection, and a LAN. The gateway is the Linux machine or a Windows XP machine. When the wXP is routing, for a host inside the LAN, the latency of, for example, the Counter Strike game to a given server is around 20 to 30

Guys All the recent discussions recently, and the knowledge of a 2.6 port, of WRR has made me very keen on trying it. I had a look at the docs and examples know but my mind is not in a very receptive state. Take this simple example. Incoming internet connection of 1mbps. Shared between up to 25 users simultaneously. I know that WRR can fairly distribute the traffic amongst the currently

Hi, I''ve a local LAN consisting of about 150 machines. I''m using a Linux machine as the gateway machine which inturn connects to two different ISPs. My question is can a Linux based machine match the performance of a hardware based routers provided by Cisco,... OR is my decision to go for a Linux based solution is a wrong one?. Is there so much difference between these

please, help, i have build vpn server (suse 9 + poptop), i have managed to implement tc htb in ip-up script, but every client has own ppp interface (ppp0, ppp1, ppp2...), and my idea is to share available bandwidth, not to limit connection, how to build root tc rule, when I have more then one interface?... please any one width experiance regards _______________________________________________
