Nothing interesting about me. This is not the user you are looking for. Move along. Move along.

@Sirex: Oh well, yes that is true. But the network will be 10x faster.

comment What happens when a consumer switch receives a VLAN-tagged Ethernet frame?
Eh. Linux end-point devices handle tagged frames just fine. I have seen them do it.

comment Copy large files to multiple machines on a LAN
@user606723: Doesn't everything modern? Maybe some consumer junk does not, but I haven't run into anything with broken multicast in a while. Too much uses it these days. I think Windows Active Directory even uses multicast.

comment What is ECC ram and why is it better?
@JeffAtwood: And, like everyone I am sure, I've occasionally had to reinstall an application (Office. Visual Studio.) because it has apparently gone insane. App bug or ECC error causing a corrupt disk file? Who knows if you don't have ECC?

comment What is ECC ram and why is it better?
@JeffAtwood: Nothing usually, but I have had the occasional blue-screen for no apparent reason. On systems I have which do have ECC I will see a couple of single bit errors each month.

If it is multicast packets then why is the wifi sending them? It should only be sending a multicast packet to a network if there is someone listening for it on that network.

comment Linux IPv6 Transparent Proxy (but Linux doesn't support NAT on IPv6!?)
@coredump: Because transparent "Just Works" while automatic proxy only sometimes works and the users think the internet is broken.

comment Will everyone having Globally Accessible IP's in IPv6 be kind of a security nightmare?
@JohnGardeniers: Your concern is why IPv6 added temporary private addresses. Windows uses them by default. What it does is outgoing connections use a randomized temporary address. Incoming connections can connect to the permanent system address if you have publicized it.

comment How do you make it obvious you are on a production system?
#1 is an interesting idea but impractical because scripts running as daemon users might need to use rm, chmod, etc.

@symcbean: that is not what Sionide said. He could have meant after you SSH into your user account.

comment Make a program un-uninstallable by Local Admin
Agreed that the problem is users having admin. On the other hand, I would not want to work anywhere that won't let me have admin on my workstation.

-1 because your answer isn't very useful. 3.0 may be too new this month. But when people read this three months from now that will no longer be true.

comment Is it valid to have part of an IPv4 address set to zero?
@Ritesh: If the interface rejects an entry with a 0 then you cannot use some of the IPs on the network.

comment Ordinary users are able to read /etc/passwd, is this a security hole?
@joechip: If you had to use a service for ID to user-name translation...well, it would be trivial to just ask it to translate all UIDs from 0 to INTMAX.

comment How do I protect my company from my IT guy?
Definitely. Also, someone needs to verify/audit the documentation to know it is currently accurate and works.
