It is not ADSL or Wifi, so probably I'd need to live with 3 routers - one for my Tata Indicom, the Wifi Router and the Dlink one.

Nagarjuna recently we replaced our cisco routers in our LAN with vyatta which is Nagarjuna based on a fork of GNU zebra.

Our load Nagarjuna balancing is working fine with vyatta. we are the server Nagarjuna image provided at their site: http://www.vyatta.org/ I can see from your gnowledge.org's IPv4 address, that it is part of a /16 allocation to TIFR. So you're probably using your vyatta box as border router, receiving route updates from the peers. So I think, a simple script to monitor the connectivity should include the following: 1. Do a ping to an IP address after every n seconds, from each of the interfaces, '-I' option of ping, and if exitcode from any ping is non-zero, it means the link is not working and should not be included in routes. 2. After you get the list of interfaces, you can create a multipath route based on them. HTH P.S.

Hey guys, thanks for all the Linux suggestions, but I need a ready-made black box for a friend in B'lore.

I've seen a couple of SMC barracuda ADSL routers that will handle dual links and do some failover stuff. I'd guess you already had modems for those links ? Cant remember from memory what the model number was, but google should dig up something. Also, i dont think the device does any load-balance. But it does do failover from one link to the other and back again when quality is back at some fixed limit. We used to use these 5 - 6 years back with ADSL - ISDN failover in typical office setups. But since the WAN interfaces exposed are all ethernet, I'd imagine you can plugin a cable modem instead of an isdn one with no real issue. Watch out for the ones that directly talk isdn-nt, you dont want those! Not sure if this helps, but its *something*. You could always get some micro-ITX kit or gumstix type machine, linux'ify it and post it over :D - KB -- Karanbir Singh : http://www.karan.org/ : [EMAIL PROTECTED] ___ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Next Event: http://freed.in - February 22-24, 2008 Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/

Re: [ilugd] [OT] Load balancing router
If an old PC is available then do try considering Endian Firewall Community Edition. I have been using it for quite sometime in my office. Works great as well as unattended and most features are supported out of the box. a few cyber cafes in my areas have started using it as well and they are pretty much satisfied with it and its web interface makes it easy for the dumb as well. And yes it does support load balancing as well. Regarding HW based thing I guess u may try a hand at Linksys WiFi Router upgrade their firmware with a linux firmware like DD-WRT and have fun, but I guess for load balancing you may require two such routers. http://www.dd-wrt.com/dd-wrtv3/ http://www.wi-fiplanet.com/tutorials/article.php/3562391 http://www.wrtrouters.com/guides/upgradetolinux/ You may read about a few other such distros at http://ezinearticles.com/?WRT54g-Linux-Firmware-Distributionsid=118837 Regards Dhiraj Gaur On Mon, May 26, 2008 at 6:27 AM, Raj Mathur [EMAIL PROTECTED] wrote: On Monday 26 May 2008, Karanbir Singh wrote: [snip] I've seen a couple of SMC barracuda ADSL routers that will handle dual links and do some failover stuff.
