comment running a remote command with ssh seems to hang all other network activity
@AD7six I started off looking for why I was having connection issues and so that's how the issue presented itself. I'm using asynchronous code that would hang at the SQL statements but the side effect was nothing was attending to the network connections due to that hanging.

@AD7six - please make that an answer! I'm using InnoDB so I didn't think that was an issue, but apparently I needed to add --single-transaction to mysqldump to stop it from locking everything up.

comment What's the best way of handling permissions for apache2's user www-data in /var/www?
Instead of "2775" you may want to use "g+ws" so you just add "write" and "sticky" to the group permission and leave the rest. Likewise, replace "0664" with "g+w". Otherwise, if you have files that should be executable, you'll lose that setting on them. Or if you have files that shouldn't be "other" readable they'll become readable, etc...

comment SPF failure with gmail
okay, I think this seems to be the case... I'm sending emails in gmail with my domain name as the "from". The email is sent through gmail servers and it adds a "Sender:" with my gmail address on it. Am I understanding that correctly?

comment Tell NetworkManager to ignore or not probe rfcomm0
I think the person was also hoping I had found an answer myself. I had seen that other page already when I tried finding an answer with Google. However, I can't keep disabling the Network/Modem Manager and rebooting just to do a quick command over the rfcomm serial. The best solution I've got so far is to "type really fast" in between the probing AT commands. :P Which is just enough for me to get by for the moment.

comment Is there a security downside to having iptables ignore the loopback interface?
should I also add <code>-A OUTPUT -i lo -j NOTRACK</code>?

comment Trying to make iptables stateless is causing unforeseen filtering
Okay, maybe my problem is my misunderstanding of how DNS works. Aren't DNS lookups done by sending a request that would be handled by an OUTPUT rule?

comment Trying to make iptables stateless is causing unforeseen filtering
@DavidSchwartz - The DNS is working fine until I change either of the rules mentioned in the question. I don't understand why removing a rule related to TCP input state would suddenly kill DNS. Or telling iptables to stop tracking OUTPUT and PREROUTING would kill DNS.

@Zoredache - dude! I'm trying to remove the state dependent rules, but removing them is causing troubles... hence the point of my question!
