However, this didn't affect the other server, as it is running multiple IP addresses on that LAN. Here is the application: A customer of mine has colocated two servers with us. He is a reseller for Megapop. These boxes run primary/secondary DNS, and radius. Since Megapop doesn't support secondary radius servers, I had to develop a failover solution. Here is the configuration: IP address queried for radius: 208.244.234.131 IP of reseller2 (primary DNS, backup radius): 208.244.234.132 IP of reseller3 (secondary DNS, primary radius): 208.244.234.133 As of now, reseller3's main address is 208.244.234.133, and I have .131 ifconfig'ed up on it as well. I have written a perl script that will manage the IP so that whenever the primary radius server is up, it will have .131. Whenever the primary is down, the secondary has .131. This is when I noticed that reseller2 (.132) refused to use the alias'ed ip properly. I know the script works, I tested it fully on some differnet machines. However, I can't implement the script until I figure out how to restore proper ifconfig functionality. Thanks in advance for any help, Andy ---------------------------------------------------- Andy Dills 301-682-9972 Network Administrator Fax 301-620-9634 Xecunet, LLC www.xecu.net ---------------------------------------------------- Dialup * Webhosting * E-Commerce * High-Speed Access To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
