comment famd/gamin timeout issue with courier-imap
Okay. Our experimentation shows that we can reduce the number of errors by disabling IMAP_ENHANCEDIDLE, possibly disabling TLS_CACHEFILE & TLS_CACHESIZE (This is suggested in the config file). This issue also seems to be resource related, so we're looking at more general resource tweaks.

comment famd/gamin timeout issue with courier-imap
Tonin, did you ever figure out the answer to this? We're running into a similar error. CentOS 6, VMware ESXi, Courier IMAP. No obvious load issues.

comment What is the difference between syslog, rsyslog and syslog-ng?
I would argue that both syslog-ng and rsyslog are 'next gen', or at least the newer replacement for the older syslog. Both are comparable in terms of features, but the syntax for both is very different. syslog-ng has it's own unique syntax, while rsyslog's syntax is more like the older syslog syntax.

comment Apache refused to include TLS1.2
Don't replace /usr/bin/openssl with something else. It will break your system, as many things depend on it. Instead, install OpenSSL to another location like /usr/local and point Apache at that.

comment Apache refused to include TLS1.2
/usr/bin/openssl is the commandline utility for using openssl. The Ssl module for Apache is different. Look at the LoadModule pines on your httpd.conf file. You probably do not need to recompile Apache.

You need to make sure you are loading the new module which is in a different location from your old module. What do you have for your load module statement?

Note that this may result in some database corruption, but generally MySQL should be able to recover just fine.

comment Apache on CentOS 6 Unresponsive
Check your access and error log and look for the 404 error, and then see if the page mentioned in the logfile matches what you set in the configuration file. You will need to restart or reload Apache.

Steven, to check for issues with Swap, use a utility like top. Many basic sysadmin books will show you how to do this.

This does explain why the problem happens, but some reasoning would be helpful.

comment How can I validate a ZFS snapshot image residing on a backup system?
Glad I could help. ZFS is a great filesystem, but finding good examples outside of the Solaris docs can be hard.

comment Seconds_behind_master value keeps on increasing in MySQL replication slave
MySQL 5.0 reached it's end-of-life some time ago, and the latest MySQL 5.0 release is 5.0.96 (you have MySQL 5.0.77). Many replication bugs have been fixed since MySQL 5.0.77, and replication performance has improved quite a bit since even MySQL 5.1. There area many reasons for MySQL replication delays in older versions of MySQL.

comment freebsd cannot start mysql for the first time
The permissions 1777 are way too permissive and should only be used temporarily, and should generally be avoided. Leaving those in place for a long time is a security problem.

Running dd ... && sync has the advantage that it works on multiple operating systems, beyond just GNU/Linux.

comment Can OpenSSL be used to debug an SSL connection to a MySQL server?
Hm, I suppose the behavior I'm talking about is how STARTTLS works, according to en.wikipedia.org/wiki/STARTTLS .

Remember -- at some point, you modified your DNS records to use Google. Undo that step.

comment Linux CLI command for ~“what is this machine”?
GNU/Linux doesn't provide a single, unified "standard command" to describe a server. facter is one of the most commonly used alternatives, however.

comment Why is Linux kdump not writing to /var/crash?
No I do not have a watchdog rebooting the machine. Turns out that the LSI controller + Samsung SSDs are periodically freezing for reasons that we don't totally understand.
