What's to say? Check my personal website for a touch more detail, if you want to. I sysadmin free software professionally through my own little company. A long time ago, I and a co-author wrote "Building Linux and OpenBSD Firewalls" (Wiley, 2000). That's it.

comment Can devices steal MAC allocated IP addresses?
This is not a very good explanation of how ARP works. When XXX:999 connects, it will do more than just listen for packets to 192.168.1.20 - it will respond to ARP requests for that address, actively causing confusion, loss, and desynchronisation of TCP connections.

comment Why is my ssh output hanging until I kit a key
Don't take this the wrong way, but home questions are explicitly off-topic for SF, as our help page makes very clear.

What does your network admin say about the problem?

comment When is a mainframe better than distributed servers, and when is it worse?
For me, it would be much less bad question if you'd related it a specific workload; eg "we have the following functions to perform, which we currently think will need to be on X distributed servers, but are also considering just one mainframe instead. What factors should affect our decision?".

comment Wireshark : Why is a TTL value of the DNS response not 128?
The response packet will presumably have come through several hops, each of which decrements the TTL.

comment Setting up home DNS with Ubuntu Server
OK, have you now tried adding a wildcard record * IN A 192.168.1.5 (my sincere apologies for getting the fields in the wrong order above)?

comment Setting up home DNS with Ubuntu Server
Fair enough - I do agree with tombull89 about it being a well-written question. Have you tried putting the single line IN A webapp 192.168.1.5 (with a leading TAB) in /etc/bind/zones/db.example.local? I understand you want wildcard DNS, reverse-resolution, and so on, but try getting a single forward host to work first, to simplify the problem.

comment Setting up home DNS with Ubuntu Server
Zeophlite, please don't take thie the wrong way, but you've been a member for a while. Have you, all that time, managed to miss the line in bold in serverfault.com/help/on-topic that says that SF is not for "Anything in a home or development environment"?

comment What is the best way to get optimal processing power?
Trevor, the help documents are pretty clear that anything in a home environment is off-topic for SF (serverfault.com/help/on-topic). I beg you to read them before asking any further questions, and not to take it personally if this gets closed.
