Hi, can anyone help me with this problem i''ve got! I have a problem with routing on my Mandrake 7.2 Linux Box i was wondering if you could help me with. I live in Australia and as broadband access isn''t very available at the moment, i have 2 modems to dialup to my isp (dynamic ips assigned) to increase my bandwidth at an affordable level. What currently happens is i have a

i''ve read your http://lartc.org/howto/lartc.rpdb.multiple-links.html article as well as Advanced IP Routing (esp. chapter 10.4) and still unable to make this thing work. am i that helpless? :) is there anyone to guide me through the multiple ISP setup? into details. i got 2 dsl connections from different ISPs (A and B), both connections use PPPoE, both got assigned with dynamic IPs

Hello! I have trouble with multipath routing. Those options are enabled in kernel: [*] IP: policy routing [*] IP: equal cost multipath [*] IP: equal cost multipath with caching support (EXPERIMENTAL) <*> MULTIPATH: round robin algorithm But issuing: ip r a 1.2.3.0/23 scope global equalize nexthop via 80.245.176.11 \ dev eth0 weight 1 nexthop via 80.245.176.13 dev eth0

Greetings from a newbie! (Well, to this list anyway) I''m having a problem and I hope someone here might be able to help... I am strongly expecting an answer along the lines of "upgrade to v2.4.x", but I would REALLY preffer to avoid that for now... The setup: "Home brewed" v2.2.24 (will patch to v2.2.25 later today) with the DS8 patch applied. Currently

I have a private lan that is connected to the world via 3 dsl lines. I put up a linux box that handles all the dsl lines, lan gateway and all is working well...until...one of the dsl lines goes down. My routing table is: x.x.x.x dev ppp0 proto kernel scope link src x.x.x.x x.x.x.x dev ppp1 proto kernel scope link src x.x.x.x x.x.x.x dev ppp2 proto kernel scope link src x.x.x.x

Hi All, I''ve configured a mutlipath as detailed in the HOWTO. For the most part it''s great, but when the cheap DSL line drops it''s connection, as it regularly does, the outbound routing doesn''t automatically use the remaining path for internal outbound traffic. Ip route show lists no default route once the default path dies, and if the ppp connection is

Hi There, I am also trying to do the same for my network. I have two links from different ISPs and I want to configure a failover and load balancing Linux router. I am facing same problem here, that how to detect link failure and let Linux box switch the gateway. I know it works when the first gateway is physically down and not reachable. But what to do if my link is up but there is problem

Hi, I am tring to us ip route to load balance between two interfaces. ip route add equalize 10.200.1.0/24 nexthop via 10.200.0.2 dev neta nexthop via 10.200.0.2 dev neta2 Where neta and neta2 are gre tunnels. Testing show that packets travel in a single sided manner. Do I need to use the multipath (IP_ROUTE_MULTIPATH_CACHED) module? thx jason

Hi, is it anyhow possible to tell the other end of the ppp link how he should queue the packages? I have a ppp link to my isp and would like to control the order of packages send to me. I would like to give uucp a lower priority than http. Is this possible? Has ppp any special features to control such things?

Hi, I need a help on Linux routing, if you have some sparse time. I''m based in Madagascar and my English is not good; so please forgive me. *What I want to come-up with: *My main goal is to download using two modems at the same time, and combining their bandwidth, but I have failed miserably. The reason is this: our country is still using poor slow internets, and I have seen on the

I am one of the few people left in the US with a ISDN connection to the internet. (Internet cable has been promised "Real Soon Now" for a couple years). Worse, my home network runs on a decrepit Cisco 2500 series router, and is double-natted via a firewall, which is why I currently use iax to call anywhere. I have been making ever-increasing use of my asterisk PBX, and I'm ready

Hi, There''s some very silly mistake i''ve done in my configuration. I did by reading material on web. I''m enclosing my configuration script below.

Kindly please guide me what i can do to make it work..dynamically.. Also there is a

I am attempting to get multipath working with device-mapper (CentOS 4.2 and 4.3). It works on EVERY install of mine from RH (also v4.2, 4.3), but the same multipath.conf imported to all my installs of CentOS do not work. Note that I have tested a working 4.2 configuration file from RH on CentOS 4.2 and a working 4.3 configuration (it changed slightly) on CentOS 4.3. Neither worked. Our production

Hi There, We currently using iproute2 for load balancing. However we need more upload speed as we load balance over 3 dsl lines. I''ve been looking for a way to combine the upload speed to more faster. Found a site called www.upstreaminter.net where these guys bond the adsl channels to improve uploads, Since downloading is problem as its need to know the ip address of the downloader they

OK, I''m stumped. I''ve read through most of the LARTC HOWTO and have yet to find a basis for what I need to accomplish. I have a Linux box that controls access to and from the Internet at my workplace. We have a number of remote employees that connect via PPTP and IPSEC to the office''s internal network. Some of these remote employees are currently using SIP phones.

Hi, I am currently using a 2.4 kernel with multipath routing patch v5 to send outgoing packets in a 1:1 ratio over two lines, however the lines do not actually have equal upstream bandwidth, one has 800kbit and the other 600kbit, so ideally I would like to send packets in a 4:3 ratio, is there anything in 2.6 or a patch for 2.4 that could be used to do that? I tried this ugly hack but it

We've been wrestling with this for ... rather longer than I'd care to admit. Host / initiator systems are a number of real and virtualized CentOS 5.5 boxes. Storage arrays / targets are Dell MD3220i storage arrays. CentOS is not a Dell-supported configuration, and we've had little helpful advice from Dell. There's been some amount of FUD in that Dell don't seem to know what

Hi. I''ve trying to balance outgoing traffic by using multipath routes, but I can''t get it to work. Only one of the routes are used. I''m adding the route like this: ip route add table 101 default \ nexthop via X.X.X.X nexthop via Y.Y.Y.Y It shows up the routing table like this: default nexthop via X.X.X.X dev vlan110 weight 1
