comment Options for non-virtualized network interface isolation?
I am baffled by what you're trying to accomplish. Local traffic cannot be DMZ->LAN or LAN->DMZ, it's just local. (The traffic originates on this machine and is destined for this machine, right?) This machine is not routing remote traffic and there's no conceivable security reason to stop the machine from communicating with itself.

comment mysql socket issues
The errors that you are experiencing are explained in the logs you pasted. Look for "ERROR". The server is not running.

comment How to telnet a computer name?
From what OS to what OS? And what software is running on the computer you're trying to access? (Bonjour? NMB?)

answered Rsync from CIFS mounted Windows shares is slow. Why is this? Are there alternatives for file copy with checksum support?

comment Google SMTP Connection Timeout
@Cerin Exactly. And when you send mail through Thunderbird, you use a server that has specifically agreed to accept mail from you and you access it as a client.

comment Google SMTP Connection Timeout
@Cerin Mail just doesn't work that way. Unless you have special arrangements with Google, you get the normal arrangements, where part of the sender's responsibility is to accept bounces. If you want an arrangement where you can send mail without having a real mail server, someone else has to do your share of the work -- you need to hand the emails to a real mail server that has agreed to accept them from you. Google has not. And you aren't doing your share.

Yep, he has confirmed he's not using ADB. So the architecture of ADB isn't relevant.

I really doubt he's using ADB. It's much more likely he's using tethering.

What program do you use on the phone? Is it the OS's native tethering?

How exactly are you "connected to the internet via Android"? What software are you using? What mode is it in?

comment Google SMTP Connection Timeout
My point is that it's not reasonable to expect it to work. The question is just as much why it was working before as why it's not working now. You're not handing mail to your own mail server, you're not receiving mail as the final destination, and you're not relaying mail from one server to another. Those are the only configurations that should be expected to work.

comment max files per directory in ext4
Just be cautious that if an attacker has the computational resources, he can deliberately create malicious data that will land in the same directory. An attacker with decent resources and today's technology could produce hashes that have the same first 9 hex digits (and thus collide in the first three directory levels) at a rate of about one every ten minutes. And, of course, full MD5 hashes can be generated today.

comment Site works on one port but not another
Troubleshoot. Does netstat show Apache listening on port 80? What IP is it bound to? Can you telnet to port 80 from the local machine? From a remote machine?

comment Is there additional risks to firewalling between VLANs on a single Dot1Q trunk, as opposed to discrete ethernet links?
The key point is that the device on each end of every physical link that carries packets from different security zones must be correctly configured.

comment Can someone explain to me what “wget -O - -q icanhazip.com” mean?
No, stdout is the normal output pathway which, when you launch a program from the shell, is connected to your terminal/console.

comment set PROMISC mode for switch in Linux
I can't figure out what it would mean for a bridge to be in promiscuous mode. Promiscuous mode is about how you handle packets not sent to your hardware address and a bridge doesn't have a hardware address.
