<snip> > Any thoughts on either solution? You want to check into what the linux High Availability and Virtual Server folks are doing: http://www.linux-ha.org/ http://www.linux-vs.org/ For basic fail-over, a simple setup using heartbeat/keepalived is probably enough. If you really want to share state information between systems through cut-over, things can get quite a bit more complex, typically involving things like shared storage (ie: SAN) and cluster file systems (ie: GFS), and I'm not sure it's possible to share kernel state information (ie: NAT/Masquerading tables) between systems. Depending on how far down the clustering path you wish to travel, the minimalistic LEAF distribution may not be best suited for your needs, although you can setup basic fail-over with bering "out-of-the-box": http://www.leaf-project.org/doc/bucu-keepalived.html - -- Charles Steinkuehler [EMAIL PROTECTED] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGJ6f+LywbqEHdNFwRAnQUAJ9uWFJyeXJQZNkAaR2Yr/YOktaqwQCguM2t mFqpw4aNH0KScOeBkl1w9jY= =UlI8 -----END PGP SIGNATURE----- ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
