Hello. I have the problem that I have two gateways on the same subnet, 80.237.244.1 and 80.237.244.33. Both gateways are 100 MBit cards, so I have 2 times 100 MBit to the Internet. The NIC in the server is a gigabit-card, so this card is easy able to use both gateways for outgoing traffic. Now I just want to use both gateways for my outgoing traffic but no matter what I do, it doesnt work. I

...here a better way than just running 'upsdrvctl start' hoping to find a driver that works? There is no source with the Linux driver supplied and neither is there any license agreement. Is it legal to reverse engineer? If anyone wants to look, the Linux software can be had from here: ftp://yesican.chsoft.biz/pub/SmartLinkUPS Even if you're not sure of the answer, perhaps you'll venture a guess or two for me to check out? -- gypsy

Hi all, After posting some emails here and googling in the net. I have now a little clarity where and how to start bandwidth Management. Hope I can still be guided though. My understanding is I will be needing these modules and linux utilities. I hope someone can confirm. 1. I need to use iptables/ebtables for packet marking. 2. I can use tc for packet shaping. 3. I can use bwm_ng for

...r with an external IP configures the external interface to listen on that IP. I have had TERRIBLE luck trying to use iptables to DNAT so if DNAT needs to be done, any advice that includes tested and working examples would be sincerely appreciated. There are 3 computers connected to the switch: 1) yesican.chsoft.biz 206.72.89.154 This also listens on eth1:0 to 206.72.89.158 as ns.chsoft.biz 2) news.chsoft.biz 206.72.89.155 3) phil.chsoft.biz 206.72.89.156 yesican (AKA ns) and news are both Slackware Linux boxes and each has a working HTB script. news'' (non-business hours) script i...

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

Hello everybody I’m french and ‘im a network administrator. It the firs time I write on this mailing list ..

Hi List, New subscriber/lartc user here. Have read the entire lar&tc howto, alexy''s ip_cref, etc. and must say, this makes iptables seem downright *easy*. I''m trying to build a three-legged linux router (WAN/LAN/DMZ) and have had it more or less working with iptables but would like to learn layer2 routing with iproute2. I have an adsl/29 network and would like my

Yes, this is a dumb question. I haven''t the time nor the resources to dig into the guts of this right now, so perhaps someone will take a few minutes to help, please. I just implemented a classic "nano" multipath setup. The script is at http://yesican.chsoft.biz/lartc/rc.nano1 What I need to know is if I need SNAT in the firewall when a packet comes in on the "wrong" interface. If I do, please provide an example "iptables -t nat" command and a description or diagram of what it accomplishes. ISP2 has a network address of 66...

I hope this list is still active. I''m an experienced Linux Sysadmin, but I haven''t done much in the way of routing. Due to a decision made by my higherups, I need to jam a computer between my ISP and my LAN to do bandwidth throttling. My current setup: 1 Crappy Cable Modem (7Mb/768Kb connection) with a static IP. 4 servers (all have static, routable IPs) - One of which is

I visited yesican.chsoft.biz and the author proposes a way to match packets by less than some size . Here is the thing: match u16 0x0000 0xffb0 at 2 With this match he says that packet with less than 80 bytes will match the rule. Well, 0xffb0 translates to 1111 1111 1011 0000 (which is -80 BTW). So, if I am cor...

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.

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

Hi Is there a way of marking packets by mac address instead of ip or ports using a "tc filter u32 match"? I read somewhere that I could use the offset -8 and -14 to grab the mac addresses but if I use anything lower than -8, for example -9, I get an error. I''m modifying the wondershaper script to cap the download speed by mac address. Any sugestions?

Hi, A friend of mine has 2 lines of 512kbps terminated in two Linux boxes. He now want to remove those 2 boxes and have some device which will loadbalance the two ISPs and also have a failover arrangement. But he has agreed to give me a chance to do it on Linux for my own satisfication. Is this easy to do with lartc? How do I go about it exactly? I have very less time to do it since his
