Heres the goal: Have all LDAP queries (login purposes) go to serverA, serverA will then take that LDAP query and forward it to either serverB, serverC, or serverD based on availability and resource usage of each server. DNS round robin is out of the question. We want true failover, high availibilty. Does anyone have any suggestions? Is LVM a good solution? SLES 8 (2.4.x kernel) Thanks, Ryan

You meant LVS, not LVM right? If so, LVS has a good reputation, but I don't know if it handles LDAP or not. If you want to consider making serverA a 2-node HA cluster, you could post your question on Linux-HA. SLES supports the Linux-HA infrastructure and SUSE provides one of the main Linux-HA developers. http://www.linux-ha.org/ And I see they even have a link to a 2 year old HA LDAP article: http://linuxjournal.com/article/5505 You can subscribe at http://www.linux-ha.org/contact/ Greg -- Greg Freemyer
Dear list, just re-installed Suse of my wife's pc. Strange thing is, that the network seems to be dead. The device eth0 is created, but rx-counters remain zero, tcpdump shows no traffic, except when ping-ing on the same machine ifcfg eth0 shows no indication of any problem. First assumption could be that the board (3C509b, ISA-bus) is broken, however, if i reboot the machine under M$, the device works happily. I know, if you use the latest, state-of-the-art boards, the is a chance that it's not supported yet, but this old board is quite a different chapter. With older versions (Suse, RedHat) is use to have no problems whatsoever... Suggestions (besides replacing the board) ? Hans.

There is a package called netdiag that contains utiliities to get the contents of the hardware registers on the NIC. That may help Paul -- Paul Hewlett (Linux #359543) Email:`echo az.oc.evitcaten@ttelweh | rev` Tel: +27 21 852 8812 Cel: +27 72 719 2725 Fax: +27 86 672 0563 --
