[CentOS] Machine becoming irresponsive

2012-01-23 Thread Dotan Cohen
There is a CentOS 5.2 machine that is sometimes found to be offline. It runs a few websites but nothing very high traffic. I happened to notice a few days ago that before it went down, one of the sites written in PHP was throwing errors that it could not connect to the MySQL backend. Two hours late

Thanks, all. I suppose that you all are right, considering that 5.2 is no longer supported. I was under the impression that this is an older but up-to-date install. This server sits in a datacenter hundreds or thousands of kilometers from anyone related to it, so I will back it all up via rsync. Do

[CentOS] Dovecot under CentOS-6

2012-01-23 Thread Timothy Murphy
I've been running dovecot on a CentOS-5.7 server. Now I'm moving over to another server running CentOS-6.2. I thought I was running dovecot on the new server, but in fact there was an error during the setup, with the result that incoming mail finished up in /var/spool/mail/ rather than in ~/Maildir

This thread has been beat to death, so perhaps my $0.02 isn't so meaningful, but I wrote a set of rsync scripts in php that I've used for years to manage terabytes of backups going back years of time. It's called TINBackupBuddy and you can get it at http://www.effortlessis.com/thisisnotbackupbud
