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 dont know if this problem is related to shorewall, but as here we have a lot of firewall experts ... :) We are using a Leaf box (1GHz 256MB RAM) for a network with normal traffic of about 6Mbps but peaks of up to 40Mbps. The chipset of the ethernets is a Realtek. We are experiencing some high latency high CPU usage issues (the CPU is at 90%) and we discovered the process

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.

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 All, Wondering what sort of real world mileage people are getting out of different internet connecions - i.e. different DSL connection speeds, cable modems, etc... Is it reasonable to hope to carry 10 - 15 concurrent calls on a 768K DSL? I'm not talking about theoretical BW or looking for any difinitive absolute guarantee... With DSL and Cable - there is no guarantee, so I'm

Guys Reading through my lartc mail, and thinking on how to tackle my next shaping solution, gave me an idea. I''d like to propose this idea for scrutiny and if it sounds viable I''ll definitely need to start developing in due time. For me in my day to day work with developing network application specifically geared for middle-tier ISP''s, and reading on other peoples

(Sent to linux-raid, linux-kernel and ext3-users since I'm not sure what type of issue this is) I've got a test system here running Redhat 7.1 + stock 2.4.9 with these patches: http://www.fys.uio.no/~trondmy/src/2.4.9/linux-2.4.9-NFS_ALL.dif http://www.zip.com.au/~akpm/ext3-2.4-0.9.6-249.gz http://domsch.com/linux/aacraid/linux-2.4.9-aacraid-20010816.patch All three patches applied

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

Hi, This morning I had some failed calls. On the console (and in the log) I saw the error "Unable to allocate channel structure". Before I restarted the process, I checked it's memory usage in ps and glanced at my free memory in top. Asterisk was using a normal ammount of memory, about 40M. I don't think this was a system limit. This was running Asterisk v1.0.2. Below is

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/

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 all, First of all I repost this email in shorewall list as there are a lot of firewall experts here that might know what the hell i going on. We have also posted this on the linux bridge list (we needed acceptance first) and leaf list. Very thankful for your understanding. We are experiencing a very strange problem and would need some help. We have a Leaf / Shorewall based box (actually

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? Any suggestions on this please? With warm regards, -Payal _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc

Hi, We are trying to validate Asterisk as a media gateway PRI <-> SIP with two T400P (8 T1s) per box. The first experience with BOX1 (Compaq, 2.53 GHz, 1 Gb RAM) and just one T400P was encouraging - on the load test with 3 T1s worth of calls we had on average 75% idle CPU. Not so with BOX2 (Dell, single 2.6 GHz Xeon, 1 Gb RAM, 2 T400P) and BOX3 (Dell, dual 2.6 GHz Xeon, 2 Gb RAM, 2 T400P,

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
