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.

comment Linux mail command not working like it used to
What's the new and old version of the OS? You probably simply aren't running the same 'mail' command. Check man mail for the options.

comment Puppet generating variables inside script
There are other ways to make something like this work if you had a puppet server, but I believe you can do it it in 2 puppet runs if you're careful with conditionals.

@KronoS: Yes, I'm aware that the communities and sites are very different. Compared to Bicycles.SE: SF is a significantly larger site. SF has a larger pool of active close-voters. SF is significantly more tolerant of rude behavior. SF is better about closing not-constructive questions quickly. SF is much less likely to hold the hands of new users.

@Ladadadada: I believe I can handle the load. On bicycles.se, I average 1 or 2 flags a day. I believe a tenfold increase would be quite manageable.

@Iain: I thought an election for 2 spots needed more than 3 candidates, and I do believe I would do a good job. I really don't expect to win, given that there's a couple candidates with much higher rep (and other metrics) now.

This needs more background. Why don't you use the MySQL packages that come with CentOS?

Yes, this is software that I'm just unzipping into a directory, with no real build process.

comment ssh public key authentication
Is your public key in .ssh/authorized_keys on the server? Is your private key in one of the standard files in .ssh on your client?

comment clone ip and mac addr on wlan
@george The switch keeps track of which MAC is on which port, so when you put the same MAC on a second port it loses track of that MAC on the first port. MAC addresses are supposed to be unique, so cloning a MAC breaks things.

comment I deleted /etc/httpd/conf.d/zz010_psa_httpd.conf. What do I do?
With a DEB packaging system, you can use dpkg --search zz010_psa_httpd.conf to find what package a file belongs to.

You probably need to add $dev in there, too...

Welcome to Server Fault! While 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.

comment Why is MySQL writing hundreds of 125 byte binary log files?
That belongs in the question, both because it's hard to read all on one line in a comment and because it's essential to the question.

What's in the configuration?

Also: there's so many ways that it's possible that there's no good way to be sure it hasn't happened.

comment bind: blackhole for invalid recursive queries?
@UdoG: The server failure packet is only 31 to 32, while the referral to the root servers was probably several hundred bytes. If your server's reply is the same size as the query, or only a tiny bit larger, your server is useless in a DNS DDoS attack, since the attackers will consume as much bandwidth as they get you to send to their target. I tested against a number of likely well-configured authoritative name servers (such as google's), and they replied with "recursion requested but not available".

comment bind: blackhole for invalid recursive queries?
@TheLQ: The question refers to this being a DDoS attack. The common DNS-based DDoS attack is to send DNS queries with the IP forged of the target. Since the DNS reply packet is larger than the query, it provides a multiplier. If your server doesn't respond with a significantly larger packet, you've eliminated the reason they're using your server in the attack.
