Hello people: I''m new in the forum. I''ve implemented the script for load balancing of "Linux Advanced Routing & Traffic Control HowTo" and I''ve a question: When I run the next command : "ip route" I get the folowing information: -------------- 192.168.0.32/27 dev eth0 proto kernel scope link src 192.168.0.33 192.168.0.96/27 dev eth2 proto kernel scope link src 192.168.0.97 192.168.0.64/27 dev eth1 proto kernel scope link src 192.168.0.65 192.168.0.128/27 dev eth3 proto kernel scope link src 192.168.0.129 127.0.0.0/8 dev lo scope link default nexthop via 192.168.0.126 dev eth2 weight 1 dead onlink nexthop via 192.168.0.61 dev eth0 weight 1 ----------------------------- Is normal the part of "dead onlink" ? Is it balancing the load between both internet providers? Sorry for my English. I''m from Argentine. Thanks in advance. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
Hello people: I''ve implemented the script for load balancing of "Linux Advanced Routing & Traffic Control HowTo" on this structure: ------------------linux gateway (subnet 1) ! linux router ------------------intranet (subnet 2) ! ------------------linux gateway2 (subnet 3) ! ------------------intranet (subnet 4) and I''ve a question: When I run the next command : "ip route" I get the folowing information: -------------- 192.168.0.32/27 dev eth0 proto kernel scope link src 192.168.0.33 192.168.0.96/27 dev eth2 proto kernel scope link src 192.168.0.97 192.168.0.64/27 dev eth1 proto kernel scope link src 192.168.0.65 192.168.0.128/27 dev eth3 proto kernel scope link src 192.168.0.129 127.0.0.0/8 dev lo scope link default nexthop via 192.168.0.126 dev eth2 weight 1 dead onlink nexthop via 192.168.0.61 dev eth0 weight 1 ----------------------------- Is normal the part of "dead onlink" ? This message is always there but the 192.168.0.126 gateway is online. Do I need the Julian''s dead gateway detection patch?. Thanks in advance.

I don''t know what "onlink" means, but "dead" means just what you fear it means; eth2 has been set dead by the kernel. It could be a routing issue or it could be your firewall, or possibly the NIC is telling the kernel something bad? You really need to run # ip route list table eth2 # ip route list table eth0 # ip route list table main to see what is going on. And assure that when only eth2 is up that you can surf (perhaps unplug the WAN wire on eth0?).> This message is always there but the 192.168.0.126 gateway is online.Are you 100% sure it is online? I have NEVER seen "dead" unless it was true. I _have_ been able to send/receive on a different (wrong) interface while one interface was dead. (I have 3 ISPs)> Do I need the Julian''s dead gateway detection patch?.Well, whether you "need" it or not, I strongly recommend you apply it. You might also want to use # ip route add default equalize scope global nexthop via BLAH BLAH... rather than # ip route add default scope global nexthop via BLAH BLAH... If you run a kernel version 2.4.22 you will need to tweak Julian''s patch (I could only find a patch for 2.4.20); if you want my tweaked version (2.4.22) you can FTP it from andthatsjazz.net/pub/linux/. And I use KeepState (see nano.txt), though I have NO CLUE why it is A Good Thing <grin>. I do not ping from inside though. I run a dgd ping from outside; when the ping fails I scp a flag file to the multilink setup that triggers a flush there.> Thanks in advance. > > Marcelo.gypsy _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
Julian and Gypsy: Tank you very much for your advices. I''vent tested it yet, but I''ll try. Best regartds. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
