Never used remote logging for multilog so I can't tell you about that, but it looks pretty straight forward. NFS settings can be tweaked to improve its performance/bandwidth usage. I've only seen it chew up a ton of bandwidth when things aren't setup properly, or when a drive couldn't be mounted properly.
As for your mysql two-way replication. Ordinarily I'd say this was a bad and evil idea, in the case of the vpopmail database it should be fine. Since they key their records with text fields and not numerical ones the risk of a duplicate key breaking replication is almost non existent. Both servers would have to add the same [EMAIL PROTECTED] at the same time, and what are the chances of that... The other option though, is that vpopmail does support a master/slave setup where any writable queries go to server X while readable ones are done locally for performance. This is a better scenario than two way replication since you don't run the risk of replication breakage. -----Original Message----- From: Michael Bellears [mailto:[EMAIL PROTECTED] Sent: Friday, April 02, 2004 9:21 PM To: [EMAIL PROTECTED] Subject: [vchkpw] Server Farm.. I am in the process of migrating our qmail/vpopmail/webmail box to a server farm (Using ServerIron for Load Balancing) I have decided to log everything to a central log server (To simplify support and generation of stats), and came across the following: The following describes how to log to remote host using multilog and tcpclient: http://smarden.org/socklog/network.html Has anyone used the above - Or has comments suggestions on an alternative? I was also thinking of having mysql servers(2 to begin with) in a Mutual Master-Slave relationship (Sitting behind a loadbalancer), and have all qmail/vpopmail/webmail boxes connect to the one (Loadbalanced) IP for auth....Although I have never used Mutual Master-Slave relationship with MySQL, and do not know how effective it is? (If anyone has an alternate solution, please let me know!) We are building the NAS ourselves, and I have had a few reports that NFS was "a total bandwidth whore" - Therefore was considering running Samba only? Would also appreciate anyones experiences(Difficulty in setting up, scalability etc) with using either LDAP, Kerberos or (maybe?) Radius for auth - As I've heard NIS has security issues? Thanks in advance. Regards, MB
