You can configure your clients to use both, and, as an additional benefit, use VRRP or CARP to provide faster recover in case of failure. - LDAP Client Hm, do you mean server? In that case OpenLDAP provides replication and works quite fine if your LDAP is read-only. If it is read-write, then modifications will temporarily be disallowed when the master fails. - NTPD You should have no problem. - WebMin Sorry, I don't know this software. - Mail (Postfix) - POP3 - POP3s This is getting harder: you can have to different server for outgoing mail (using VRRP or CARP). If these are the MX for a domain, you can list them both in the DNS. Then you have two choices: _ one forwards mail to the other, from which the clients download via POP3; in case of failure you still receive all messages, but your user won't see them until the master is fixed; _ both are POP3 server from which clients download; when one fails, the other keeps working fine, but the messages which are stored on the former won't be downloadable until it's fixed. I'm not aware of any application-level solution to this, so I guess further development would probably require a read-write filesystem failover solution, which I never tried. Others have suggested heathbeat, but it's something I have yet to study. - Mailing List (Sympa) I guess it might be part of the above. Wouldn't it? bye av. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
