Real good loadbalancer is Linux Virtual Server (LVS, www.linuxvirtualserver.org). Try localhost option to distribute load to local node AND use Linux-HA (heartbeat) for high availabliliy. Hint: ldirectord as a resource in Linux-HA version 2. Also use pingd to check availability of the nodes inside heartbeat. Sounds difficult to set up, but when you get used to it it is quite simple, works good and ist VERY scalable. -- Dr. Michael Schwartzkopff MultiNET Services GmbH Addresse: Bretonischer Ring 7; 85630 Grasbrunn; Germany Tel: +49 - 89 - 45 69 11 0 Fax: +49 - 89 - 45 69 11 21 mob: +49 - 174 - 343 28 75 mail: [EMAIL PROTECTED] web: www.multinet.de Sitz der Gesellschaft: 85630 Grasbrunn Registergericht: Amtsgericht München HRB 114375 Geschäftsführer: Günter Jurgeneit, Hubert Martens --- PGP Fingerprint: F919 3919 FF12 ED5A 2801 DEA6 AA77 57A4 EDD8 979B Skype: misch42
