FW: [LARTC] Static ip addresses/aliases previously (my mistake) htb: class 10007 isn't work conserving ?!
No I am using the EN5861, just that we have two ADSL lines and only one EN5861 and rather than buying another I'd like to use linux to do the same job as the en5861, if you know what I mean. You can, but since you have two ADSL lines, you'll need two ADSL devices of some kind, whether it's a pair of 5861s, or a 5861 and an ADSL port adapter (external modem, PCI card, whatever) that Linux supports. The simplest solution will be to have the same setup for both lines. Either use two 5861s, or get two ADSL adapters that Linux can talk to. So far I've set up ppp0:0 which I've assigned one of the static ip addresses supplied to us by our ISP but when I try and route through it i.e. ip route add default dev ppp0:0 table T1 then it returns the error no such device, which it's quite right there isn't. If I route through it using the ip address of ppp0:0 i.e ip route add default via x.x.x.193 table T1 then it does work but anything that goes through it ends up using the IP address of ppp0. So both lines were supplied by the same ISP? They sure are. Due to our location we can't have an ADSL line faster than 512kbs so we've got two and I'm trying to load balance them.. But that's another story. So how can I set up the linux box to use these static IP addresses in the same way I can with the EN5861? If you want to remove the 5861 from the picture entirely, you'll need to replace it with some sort of ADSL adapter. You can't just plug a DSL line into an ethernet card. I hope I'd made myself clear, it's hard trying to explain something when your not to sure exactly what your talking about. Anyway any help with be gladly received. It would help if you could draw a diagram of your network so we could get a better idea of what yo're trying to do. Ok I'm not the best at ASCII diagrams but here goes anyway...

I've done that because I couldn't work out any other way to use the static IP address that out ISP have given us. For each connection we've got 5 IP addresses plus one for for the router. Eth1 eth2 work fine ie both have the correct static IP address given to us by our ISP but it seems impraticle putting in another 3 cards to make use of the other IP addresses we have, there must be another way.

eth1 eth2 are both connected to the EN5861 router. I've done that because I couldn't work out any other way to use the static IP address that out ISP have given us. Aha, this is a config question. You can just add as many ip addresses to each physical card as you like. I forget the exact syntax, but check man pages for ifconfig and look for aliases. Right getting the hang of this now, managed to set up aliases for eth0 named eth0:0 and eth0:1 with the correct Ip addresses but how can I route with them? When I do something like ip route add default dev eth0:0 it complains that it cant find eth0:0 as its not a real adapter. I've been searching on google to no avail and have come to a bit of a full stop.

Ok, so the Speedtouch is some sort of DSL bridge, right? Meaning when you establish PPP (PPPoE?) to your ISP, you really have another ethernet card (eth3?) connected to the Speedtouch? First, as someone else pointed out, the eth1/eth2 connections to the EN5861 are redundant. You can set up interface aliases on eth1 so it has both IP addresses. % ip addr add 217.x.196.217/29 brd 217.x.196.223 dev eth1 % ip addr add 217.x.196.218/29 brd 217.x.196.223 dev eth1 label eth1:0 PPP is set up similarly. (PPPoE might configure ppp0 for you.) % ip addr add 217.x.230.198/29 brd 217.x.230.199 dev ppp0 % ip addr add 217.x.230.193/29 brd 217.x.230.199 dev ppp0 label ppp0:0 You can continue to add as many aliases to either interface as you like. Your problem then becomes load-balancing outbound traffic, because you have two potential default routes. One is the PPPoE connection via the Speedtouch (the remote IP is probably the DSL concentrator at your ISP). The other is the EN5861 on 217.x.196.222/29 (which in turn is probably talking to the same DSL concentrator as the Speedtouch). The simplest approach (aside from defaulting everything out one interface, which you probably don't want) is to policy route based on source IP. If the source IP of a packet as it leaves the Linux router is 217.x.196.x/29, the packet should get routed via eth1 to the EN5861. If the source is 217.x.230.x/29, it should be routed via ppp0 to the Speedpath. There are examples of this in the LARTC HOWTO. How you want to set up your NAT for eth0 to take advantage of one connection or the other is up to you. -James ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/ ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
RE: [LARTC] htb: class 10007 isn't work conserving ?!
Hi all, Our ISP has given us 5 static IP address plus one router IP address and I was wondering if I could get rid of their stupid EN5861 router and set up the linux machine to handle all the static addresses and routing. I figured I'd have to set up alises for other IP addresses eg ifconfig eth0:0 xx.xx.xx.193 but once I've done that I've found out I cant use ip route to configure it eg ip route add default dev eth0:0 table server. Whats the best way to go about this? Cheers. By the way I'm running redhat 9 with two adsl connections, on is a speedtouch USB modem and the other is the EN5861 router. ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
[LARTC] ISP Static IP assinging
Hi, Not sure if this is the right mailing list for this but its kinda on topic. Apparently our ISP has assinged 8 static IP addresses to us, A network IP address, a route ip address and 5 user ip addresses. Now they supplied us with a router with 5 ports on, each one of the ports would assign a different static ip address but this broke sometime again and since then we've installed a linux machine which load balances 2 adsl lines. The trouble is the ip address assigned to it when it connects isn't anything like the static IP addresses they've provided. Is there something I have to change in order to make use of these addreses? I'm at a total loss with this and I hope I've made myself clear. Regards, Chris. ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
FW: [LARTC] ISP Static IP assinging
Hi, Thanks for the reply. Not sure if this is the right mailing list for this but its kinda on topic. It is ADVANCED routing; you have a simple configuration issue, so I hope you posted more than just here. we've installed a linux machine which load balances 2 adsl lines. The You left out a critical bit of info: WHAT DISTRO? F.E. Slackware does this in /etc/rc.d/rc.inet1 or /etc/rc/d/rc.inet1.conf Its red hat 9 It sure as hell is not doing load balancing if it isn't getting assigned correct IPs. I'm using a program called netsplitter from www.hostname.org seems rather crude but does the job. trouble is the ip address assigned to it when it connects isn't anything like the static IP addresses they've provided. Again, critical info missing: WHAT IP DO YOU GET? The IPs I get seems to be dynamically assigned from the ISP, not different every time but do vary from week to week. Each Network Interface Card (NIC or eth# where # is 0 to n) can respond to any number of IPs. This was called aliasing (a hit for your google search) but because these are real IPs, the term alias is wrong. You (probably) need only 1 of the 5 IPs for each of the 2 DSLs; each DSL should be on a different eth#. Probably should of mentioned that I'm using 2 speedtouch usb modems which as you could probably guess once connected are ppp0 and ppp1. Is there something I have to change in order to make use of these addreses? YOU assign the IPs, not Linux or the DSL device (modem or router or whatever terminology). You need to read about DHCP and NAT because it is likely that the IP assigned via DHCP begins with one of the following 10.0 169.254 172.16 192.168 which are NATted, example, internal IPs. Sorry, but I don't have time this morning to say more. Don't be sorry you responded and that was enough. Anyway I'm going to do a bit of googling on aliasing and see what I can dig up. Cheers.
