comment Syntax error when setting up master-master replication in MySQL
Cool. Um, why can't I run the command "start master" on the master 2/slave 1?

comment Syntax error when setting up master-master replication in MySQL
There are many howtos on the internet for setting up Master-Master replication. Here's one I'm following: erlycoder.com/43/…

comment Syntax error when setting up master-master replication in MySQL
Yup, start slave works! Also, the slave is working perfectly as a slave. I see "Slave_IO_Running=yes" and "Slave_SQL_Running=yes" in the status query. Now I'm trying to make the first master into a slave too, so that they can both be masters and both be slaves. The point is high availability and the ability for any of our servers to connect to either server and write to the databases.

comment Convert existing servers to a failover cluster
Also, it seems that Docker is more of an application packager? We don't do much beyond hosting some websites, e-mail, and VoIP so I'm a bit unclear how this would help.

comment Convert existing servers to a failover cluster
Did you mean Docker on Gluster? Gluster, being a distributed network filesystem, would probably work better as the underlying filesystem to Docker, which I would imagine, wouldn't even notice if Gluster is there or not. I've already got that part set up, I don't think I need to do it all over again. :)

comment Ubuntu Server hanging on adding swap
Note: The easy way of doing this with modern versions of GRUB is by editing /etc/default/grub and add "nomodeset" (separated by a space) to the end of the GRUB_CMDLINE_LINUX_DEFAULT variable.

comment What options exist for changing usernames transparently in Webmail?
Option number three is one that I had never considered before, thank you. Modifying software to suit our needs could technically be an option too, but the need for frequent security updates makes that kind of thing a huge pain in the butt. Adding users with the same mailbox is a far more graceful solution.

comment What options exist for changing usernames transparently in Webmail?
No, it's not a dupe. I saw that question before I asked this one. It's actually the reverse situation. Logging in with just the username part of the e-mail address is not a problem - if the user@ourdomain.com address exists. If it's user@hosteddomain.com, then they need to use the full e-mail address. Customers should be able to log in with either Username = user or Username = user@ourdomain.com.

No, this is backwards. Customers who use our domain do not include the @ourdomain.com part, they just log in with "myuser". Customers with virtual domain hosting include their full e-mail address.

comment PHP is not executing scripts after Debian upgrade
Maybe I'll try this out on Saturday, when customers aren't likely to complain nearly as much when we test to failure. :)

I've even tried uninstalling all the PHP packages, then starting with the simplest possible setup. No dice.

I actually noticed this beforehand. Sorry, didn't do anything.

comment PHP is not executing scripts after Debian upgrade
Nah, this didn't work. It's worth noting that Debian will automatically restart Apache when you install libapache2-mod-php5, and when I ran 'a2enmod php5' it said "Module php5 already enabled"

@TeroKilkanen: Added that to my question. I just get PHP code.

comment What should I watch out for in building low-budget storage servers?
@Evan: That's assuming that you don't make it actually easier for the attacker. The knowledge required to break into my backup server, which is also locked inside a physically secure basement at the datacenter, is higher than the knowledge required to smash the window in my car and steal my tapes while I transport them from the server room to the bank. That is, if I even bother with the step where I lock them in a safe-deposit box, and not opt instead to put them in my desk at work.

Pff. The way you keep online backups is with SSH being the only service running on the backup box, and allow only public key authentication. Then restrict inbound traffic to your one trusted IP address (ie, office), and if you're extra paranoid, only keep your SSH keys on a USB keychain unless you're in the process of logging on.

comment Interpreting and using the Asterisk “timing test” command
Well if you're looking for a DAHDI timing stress test, it's pretty clear the console command 'timing test' doesn't do anything worthwhile. There's a few places on the web that will help you troubleshoot bad 'dahdi_test' results, like here: cadvision.com/blanchas/Asterisk/DahdiPerformanceTesting.html

comment limitation of sent messages in exim
What are you trying to do? Are you trying to limit the amount of spam that gets sent through? There are other, better ways of doing that. Are you trying to limit the number of messages sent by your legitimate users?

comment What are the recognized ways to increase the size of the RAID array online/offline?
I think this is an important question. Yes, it may be too broad, but the answers so far are indeed helpful for anyone who hasn't done this before.
