comment How to get GPS time in linux from an external server?
You'll need to write some code then to look at a leap second table, see how many leap seconds have already occurred, and apply the offset to UTC time. A server that did what you wanted wouldn't actually work because the information would be obsolete by the time it got to you.

comment How to get GPS time in linux from an external server?
Do you really want internal GPS time -- the one used internally in GPS receivers with no leap seconds since the GPS system was launched? If you really do want internal GPS time, you'll either have to get it from the internals of a GPS or you'll have to compute it. I don't know of any modern device that exposes GPS time, including GPS receivers. They all correct to UTC, as far as I know. But in any event, you can convert between GPS, UTC, and TAI easily. (The last time I had a device that actually exposed GPS time, I was testing it for Y2K compliance!)

The first two links I got when I punched "NTP" into Google answered your question. Here or Here.

Maybe punch "NTP" into your favorite search engine?

comment Understanding virtual memory usage > swap + physical on Linux
This is totally confused. Overcommit is not what lets you allocate more virtual memory than physical memory plus swap space. You could do that even without overcommit. (For example, on a machine with 2GB of RAM, no swap, and no overcommit, you can still memory map a 4GB file read only, using 4GB of virtual memory.)

comment How to share bandwidth fairly and dynamically
I think your notion of fairness is naive. People care not just about bandwidth but about latency as well.

Is this a virtual machine or is this running on bare metal?

comment Cascade 2 routers with dhcp
It's all one LAN. The DHCP server will serve the LAN. You're using the routers as bridges, they don't care whether the traffic they're bridging is DHCP or not.

comment Cascade 2 routers with dhcp
"Since this in in a house, I cold have several guests over so it wont be very user-friendly if they have to give their devices a satic ip, especially since they may not even know what an ip is. Thats why its important to try and keep DHCP on all routers." That makes absolutely no sense. It's one LAN.

comment Cascade 2 routers with dhcp
"The second issue is I'd like both routers, which also provide wireless, to have a shared SSID so that moving from one part of the house to the other doesnt mean having to switch SSID's or devices flipping back and fourth on different SSID's." Why is that an "issue"? If you want them to have the same SSID, just set the same SSID on them both. What's the issue exactly?

"I still need DHCP on both routers." Why? You don't explain what your issue is.

comment Distributing Internet equally among several users
"So I want to distribute the internet bandwidth among the clients equally which guarantees a minimum of 160Kb upto 1Mbit." That assumes that what needs to be shared is bandwidth. But people care an awful lot about latency too. A "perfectly fair" distribution of bandwidth might be perfectly fair to the people using torrenting downloaders, but a person trying to play games will be awfully unhappy.

comment how to check how much memory take process
@maihabunash For one thing, you show clearly that you know that there are two kinds of memory. But then you ask about "how much memory a process holds", which suggests you don't understand that there isn't just one resource that can be described as "memory".

comment Point www and naked domain to other server
Yes. It can also become a CNAME record to the name of the machine that will house the main web server.

comment Point www and naked domain to other server
@Engerlost Yeah. Probably what you want to do is move the www subdomain. Then run a web server on the machine the domain points to just to redirect people who access the named domain to the www subdomain.

comment Point www and naked domain to other server
@Engerlost Okay, so then you asked completely the wrong question. You don't want to move a subdomain, you want to move a web site.

comment How does the DNS protocol switch from UDP to TCP?
An obvious example would be if a previous request for the same record was too long to fit in a UDP datagram.
