sort of a load balancing question
Hi, This is not a really load balancing question, but similar sort of thing. We are an isp here and we would like to set up two webservers that are completely tranparent(rsync daily). We will only be using one webserver to server all the pages, but if it goes down, we would like the second webserver to take over without any downtime. Is there any programs out there that does this? Thanks.

Re: sort of a load balancing question
Hi, Yes. But I would like to know a way to let the backup server automatically take over when the primary web server is down. Thanks. Shao.

Hi, ridgey [EMAIL PROTECTED] wrote: you could put the primary name record on the primary webserver and have the www pointing to itself, then put the secondary name record on the secondary sever and have its www pointing to itself, so when the primary goes down, the secondary will kick in, it may take a little while to filter through but would be good for like over night or on a weekend. i dont know if this is a by the book way but its works for us. This is an interesting idea. But there are some problems with this approach. 1. need to reduct TTL to minimise the take over time 2. secondary named server is supposed to maintain exactly the same information as the primary name server 3. it will not work if only webserver died, but not the dns server.
