Hello, I have configured a load balancing router using Julian''s patches and as described in "nano.txt" for two ISP links as shown below. ISP 1 ISP 2 . . | | | | | | | WAN

Hi all! After that good thread "DGD patch not detecting dead gateway" I was able to set up a Load Balancing with ping based DGD (without Julian Anastasov patch). But now I''m facing a new problem and tried some options, with only partial solutions. I made a script based on http://www.mail-archive.com/lartc@mailman.ds9a.nl/msg16257.html (Thank you Manish Kathuria),

hi all, I have a firewall with 2 gateways. Router A (main, adsl), router I (backup, isdn). In case of failure of adsl I switch to isdn. How can I know when it is time to go back? Which is a standard way to test the adsl line? TIA sandro -- Sandro Dentella *:-) e-mail: sandro@e-den.it http://www.tksql.org TkSQL Home page - My GPL work

I have a doubt. If you use such a script monitoring the link status with ping and then reconfiguring, why do you need the DGD patch? You need to do some reconfiguration (change multipath to a single default route) anyway if you use the script, right? Also, the DGD patch uses src to lookup the routing table entry, but if you have a dynamic IP for the WAN interface (PPPoE, DHCP etc), this approach

Sorry for the long descritpion of the problem, I''d like to know If I misunderstand something or if I meet an intrinsic limit of my setup. 217.58.51.162 HDSL eth1 - SRV_XP: 192.168.254.10 eth0: 192.168.254.1 -----+------------------+------- 81.121.243.250 ADSL eth3 - I want to allow incoming pptp request (port 1723) to be forwarded to srv_xp

Hi all, i''m puzzled by a ploblem and I don''t know how to debug it... I have a firewall with 2 gateways, adsl and isdn. Main gateway is via adsl, backup via isdn. I setup 2 table ''adsl'' and ''isdn''. You can find a description below. I made a script to test both tables. That mainly 1. adds an iptables -t mangle -A

I already setup several 2 gateways boxes, with rules too decide which lan should use which gateway. Now I''m stuck with a simpler problem. At home I was just making some experimental setup: * 1 adsl (ppp0) * 1 more tables in rt_tables (200 ping) called "bluff" * table ''bluff *has not* a default route root@fw-eden root # ip ro li table bluff

Hi, Is it possible to use more than one default route? I believe yes. Any comments on them. If I use more than one, where will the trafficc be diverted from?

Hello all! I applied http://www.ssi.bg/~ja/routes-2.6.8-10.diff patch to kernel 2.6.8.1 and it works fine, or almost fine. It does the load balancing well, but when one link is dropped it continues to try it. At the end of http://www.ssi.bg/~ja/nano.txt it is said to ping gateway 1 and gateway 2, for the kernel to know if that route is working, but since my linux is connected to the links

Assuming if I have rules matching the same packet, the one chosen is the lower preference value or the high ? For example # ip rule list .... 100 from 192.168.1.0/24 lookup main 200 from all fwmark 5 lookup first ..... Packet is matching both rules, the one with priority/preference 100 or 200 is selected ? _______________________________________________ LARTC mailing list /

Hi, I have 2 interfaces - one for adsl and other for LAN on my Linux gateway machine. The IP addresses are 10.10.10.3 & 192.168.10.101 respectively. Now my routing tables show this particular entry. What exactly is this? 169.254.0.0/16 dev eth0 scope link Or by traditional route -n, 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 What exactly is this 169.254.0.0/16

Hi, My branch office as got a 256Kbps b/w from their service provider at a very very high rate per Mb. They don''t require 256Kbps at all but the ISP does not offer anything low. Can we restrict the bandwith to say 64Kbps nothing fancy? How do I go about it? With warm regards, -Payal

Hi, I have 2 ftp servers with 3 identical users. I want server B to be updated of server A. Whatever changes mmade by users on server A should be made on server B say every 5 hours.

Hi, An offtopic quesiton, but I could not think of asking any other list where it might be answered. I have a client uploading a few designs (25-30 Mbs) daily at a remote ftp server. We download them in morning. Since we have a slow connection we daily waste a couple of hours downloading it. Is there any way I can download them at night. The only thing is that I am not sure of the time they

Hello all, I need a very simple routing protocol for VPN redundancy. We have several sites and each site has a Linux router and two IPCops each with an ADSL connection to the internet using different ISP''s. I have configured VPN''s between all of the sites for each IPcop on ispA and the same for the IPCops on ispB. This way, if one of the ISP fails, I change the route on the

Hi, I am taking my machine loaded with Mandrake 10.0 and Suse 9.1 to my friend''s place. She has 2 different ISP providing pppoe connections in her office. She has allowed me try load balancing on my machine on Sunday. I just wanted to know does lartc stand good with pppoe? I have heard conflicting opinions on the same. I do not want to patch my kernel at all for it. Is it possible
