When I'm not bicycling, I'm a Linux SysAdmin. I'm on the board of my local bicycle advocacy group.

Bikes are my primary transportation. A 2009 Surly Long Haul Trucker, set up as a commuter and a 2012 Trek Ion CX. I also take the bus, but do not own a car.

@UdoG: Have you tried adding allow-query "none"; to the zone "." config?

comment bind: blackhole for invalid recursive queries?
Wouldn't it be better to identify the hex strings for all domains that the server should be responding to, do the above to allow those, and drop all other udp/53 trafic?

comment What do I need to mount devices with threaded round holes in a server rack with square holes?
Our cage-nut puller looks sorta like oversized nail clippers, like the bottom picture here: dalvenjah.foxfire.net/2010/01/the-real-cage-nut-tool

comment How to restrict mailman list subscriptions to certain domains?
Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. Simply put ^(?!.*example\.edu) or ^(?!.*(example\.edu|example\.com)) in the ban list?

comment How to restrict mailman list subscriptions to certain domains?
@Zoredache: yes. Might do that for some, but when "internal" is a population of thousands, list advertisement is useful I'm also assuming the spammers have the list names saved now.

comment How to use a custom status command for a service in puppet?
@ShaneMadden: Puppet doesn't necessarily need full paths to commands, though assuming it needs them doesn't hurt anything. In addition to a some sort of default path (PATH in environment daemon was started in?) exec accepts a path param and you can set a default path with Exec { path => '/usr/bin:/bin' } or Exec { path => ['/usr/bin'],['/bin']}. There's a similar 'path' on Service, but it appears to be primarily used with certain providers for finding init scripts, rather than as a normal shell-style command search path.

"Ideal" and "Best" are too subjective

comment Puppet Ubuntu remove packages no longer required
Wouldn't it be clearer how to extend this to more packages if the package had notify => Exec['autoremove'] instead of the subscribe in the exec?

comment How to install mcrypt on RHEL5
@Jamie: The question was about RHEL5, not RHEL6. Just now I updated the example URL and made it clearer that somebody should really check that EPEL FAQ to get the right URL.

@WilliamMorris: The numbers for ip→name lookups are backwards so that hierarchy works out right.

You seem to be asking multiple different questions here. The Q&A format used here is intended for one question per question.

comment How to verify if a dedicated server is really dedicated?
@Tech4Wilco: No, it just means you don't have dmidecode install. Do you have apt or yum or something like that, that you can install dmidecode with?

comment Server RAID died. How would you recover data from its drives?
@StuThompson: HP has made a point through the years of keeping the on-disk RAID format the same. Basically with HP if the drives can be hooked up to another of their RAID controllers it will work. With most other vendors this is not true.

comment Is openldap fit for large production deployments?
@user64204: I was mostly thinking production outages. Only other problem that I can think of in the last year is firewalls sometimes silently dropping replication connections so that it takes a while for replication to finally catch up. I'm on vacation until Monday and can't get to the BDB options stuff right now.

comment Is openldap fit for large production deployments?
@user84104: We index every attribute that we know is ever queried on, paying attention to the index types. But that's more of a performance thing and your question is more about reliability...
