comment 403 forbidden when www. before url
Do you have a ServerName or ServerAlias on a block that specifies one name (site.com) but not the other (www.site.com)?

comment Can two disk images be compared?
@Steven: You can set it to compare file contents. But what I was really saying is that there's no need to compare hashes when you want to compare files; comparing the hashes takes longer, in fact, because md5sum can't bail out when it finds the first difference, whereas diff can.

comment Can two disk images be compared?
@Steven: Hashes are vulnerable to hash collision. You could just diff img1.img img2.img if you want to be sure the images are identical. One disadvantage is that this won't report how the images are different...

comment How to redirect website users to a new IP?
@Sid Ahuja: I don't think JWalker's solution works. If you're just getting a new IP, simply add both IPs to the server until the TTL expires. If you're actually moving to a new host, replace the old page with a redirect as I said and do all maintenance on the new server. You don't have to maintain a parallel website, just keep the old server sending redirects until your TTL expires.

comment MySQL problem with many concurrent connections
Or maybe it's that MySQL (sensibly) rate-limits your connections to protect itself? See mysqlha.blogspot.com/2007/08/rate-limiting-for-innodb.html

comment MySQL problem with many concurrent connections
@cuti123: so why don't you set up the persistent connections before starting the application for real? The problem may be that your DB server is limiting the maximum rate of opening new connections.

comment Migration from Active directory to OpenLDAP
Actually, Kerberos handles the authentication in that trio. Samba provides filesharing, policy, and an SMB interface to the backend functions. You can use LDAP/Kerberos directly without going through Samba. PADL does have some migration scripts which might be helpful.
