managing two interfaces
Hi, I have a computer connected with two interfaces to same network. Each one backups another. When eth0 is down, eth1 have to work. When eth1 is down, eth0 have to work. The most sutable solution I've found is to monitor RUNNING status of interfaces and change the routing table from my program.

RE: managing two interfaces
The linux bonding driver should allow for it - the active-backup mode should work as you describe (with the exception that the two links appear to be active at the same time, if it makes any difference). It is also more versatile than that, allowing for more sophisticated redundancy modes. Take a look at http://www.kernel.org/pub/linux/kernel/people/marcelo/linux-2.4/Document ation/networking/bonding.txt and see if it matches your needs.

Re: managing two interfaces
You just described teaming of your network interfaces. # On Wednesday 16 January 2008, Constantine Shulyupin wrote: Hi, I have a computer connected with two interfaces to same network.

Re: managing two interfaces
This is indeed teaming. In your case, teaming does not even require teaming on the other side of the cable pair since you do not actively intend to run the paired cables active/active.

Re: managing two interfaces
Thank you for everybody. Bonding is indeed the best solution for interface backup. For my case I looking something more simpler. For my project the best solution is to set IP of disconnected IF to 0.0.0.0 and restore on connection. On Jan 16, 2008 9:31 PM, Marc Volovic [EMAIL PROTECTED] wrote: This is indeed teaming.
