comment Why are cronjobs running at the wrong time?
@WildVelociraptor Yeah syslog will also use the old timezone data until restarted (so it's going to timestamp things wrong even though they're running at the right time). Anything else that's long-running and started before the timezone data changed will exhibit similar behavior, which is why a reboot is generally indicated.

comment How can I see Time-To-Live (TTL) for a DNS record?
@Jasen Yes, that's definitely possible (It indicates something important as well: The DNS admin will be buying drinks at the next company outing for screwing up the migration!)

comment Sendmail sends unsolicited emails
That would be my guess as well. Find and fix the offending web application and your spam problems will disappear.

comment Postgres on OS X can't find postgis extension control file
That's pretty much the solution: Install the extension for the version of Postgres you're using. :)

Formatting, snip out some UK slang, and toss some upvotes on :)

comment Why perl backticks don't see anything past the first space?
system() and backticks operate differently: The former gives you the numeric return code of the command, the latter gives you the output of the command). Presumably if the OP is using backticks (or qx//) they're doing so because they're more interested in the output thank the return code.

comment How to use two ssh daemons on one server using nginx or haproxy
@BenjaminHammerNørgaard the usual solution in this situation (if you're short on IP addresses and can't give each host/daemon its own dedicated IP) is to run sshd on alternate ports - 22001, 22002, 22003, etc. - it won't let you select by hostname, but it lets you have multiple connections to different hosts (or daemons) while only using one IP. (Your mileage may vary depending on how permissive intermediate firewalls are).

comment Incredibly slow snapshot removal
I've seen the slow snapshot behavior before with little I/O on storage but never traced it down to a cause. I always just assumed the hypervisor was chewing on the deltas in-memory. ( The machines in question were using direct-attached storage or I might have looked at SAN issues too, but I've always chalked it up to either big deltas or unoptimized code in VMWare's snapshot subsystem).

revised Is a central location for authorized_keys a good idea?
There's a new, better way to handle this that doesn't tie sshd up with LDAP.

comment Anubis as GPG proxy
Bleh :-/ If I had to spitball guesses I'd say maybe it can't find (or read, or decrypt?) the private key it should be signing with - that's just where I'd start looking but it's totally a wild guess.

comment HAproxy mysql failover
Can you also include your haproxy stats output (or hatop output if you prefer that) so we can see what haproxy thinks is going on? Also there's at least one apparent error in your configuration (you're using option httpchk to check the admin page for your MySQL server - you probably want to use option mysqlchk on the MySQL port to check the actual MySQL server)

comment Anubis as GPG proxy
Given that output it's pretty tough to guess what's going on: All I can tell you is it's dead, and it was a cat ("GPGME encountered some kind of 'general error'", which is a bloody worthless error message - thanks GPG!) – Is there any other output either on the console or in a log file somewhere?
