I have need to use HTB on multiple (5) IPs. The present setup has the DSL connection going to a switch and then each computer 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

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

Hey all, I've tried some very base configs with the powercom 2200, but I can't seem to get it to work. Has anyone dealt with these UPSes before, or know if they use the standard powercom drivers? I'd be more than happy to allow access to my test system so someone more knowledgeable can take a look (and am also willing to pay something for the solution of said problem.) -Dan

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 correct any packet with bits 4 and/or 5 set (together with any of the 4

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

Hi, I want to install customized centos on multiple systems. Can PXE boot do that ? Apart from this is there any other way of doing image copy of centos OS and installing it on several client machines through network. I used clonezilla, but after image cloning, i will again have to use the clonezilla LIVE CD on client machine to do a image restore. I want to make a clone of centos OS and

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 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.

I hope this list is still active. I''m an experienced Linux Sysadmin, but I haven''t done much in the way of routing.

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

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 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
