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 Receiver limits TCP window size to 64,512
Sounds like window tuning is restricted.

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.

comment Which standard defines CAT6?
@JurGroen I wouldn't assume that 10GE will work unless the cable is certified category 6. There are tight tolerances for insertion loss, twisting, and so on.

comment Can TCP be used like UDP by simply not sending ACK?
This wouldn't emulate any of the functionality of UDP as far as I can tell. It wouldn't be connectionless. It wouldn't eliminate all the TCP stuff UDP doesn't want like slow start, exponential backoff, and so on. It wouldn't give you a datagram service.

comment Limit CPU / Mem usage for certain processes?
Yes, exactly. The people who wrote your OS understand these common use cases and the scheduler can easily tell the difference between interactive processes that wait for things to happen and then need to respond to them quickly and background processes that need a lot of resources but in exchange must yield to latency-sensitive things. (And how would having the server under load for twice as long help? Wasting 50% of the CPU most of the time doesn't help anybody!)

comment PING icmp open socket: Operation not permitted in vserver
Is /bin/ping set-uid on the other machines? Is TCP/IP correctly set up on this VM? Do other things work like DNS, traceroute, HTTP?

Why do you think keeping your server 50% loaded for twice as long is better?

comment Limit CPU / Mem usage for certain processes?
There's an old consultant's joke that if you have a really difficult client, you give them what they ask for rather than what they need. This is such strong medicine, it's usually only needed once. Sure, that's what he asked for. But do you really think this is a sane thing to do?

comment Limit CPU / Mem usage for certain processes?
Really, you probably just shouldn't do anything. The OS already knows how to distinguish interactive (processes that respond to outside events) and non-interactive processes (processes that chug along until they've finished their work) and give priority to interactive processes.

man nice (and, possibly man ionice) is what you want.

comment Windows 7 sending all packets to one nic
"If packet is destined for subnet 10.60.194.0/28, then it should be sent to a NIC that is on that subnet, regardless of the metric." Well, that's not true. If, for example, there is a more specific route for every part of that subnet, then it won't be sent to a NIC that is not that subnet. But you are right that metrics aren't you have a unique longest-matching route.

comment Windows 7 sending all packets to one nic
The list of matching routes is compiled. The route that has the longest match (the route that matched the most amount of bits with the destination IP address) is chosen. The longest matching route is the most specific route to the destination IP address. If multiple entries with the longest match are found ... the router uses the lowest metric to select the best route. If multiple entries exist that are the longest match and the lowest metric, the router is free to choose which routing table entry to use.

comment Windows 7 sending all packets to one nic
Yes, that's the tiebreaker. But there's no tie here, one route is more specific. Preferring a less-specific route would be a very odd thing to do, and preferring a default route over a non-default route would be even odder.

comment Windows 7 sending all packets to one nic
Does Windows really prefer a less-specific route just because it has a lower metric? That strikes me as a really odd thing to do. (And several sources I checked say otherwise.)

comment See what's filling up the server memory?
You probably really don't, because that much more likely to create confusion than be of value. This particular problem is a great example of that. Understanding memory usage is a very complex subject that a very large number of people get wrong and diving into it without need it no more likely to produce good results than trying to dabble in brain surgery.

comment the name of the security certificate is invalid or does not match the name of the site
Use one of the many SSL checking sites to make sure you sent all appropriate intermediary certificates. You're not seeing the error I'd expect with this problem, but I always suggest checking it first.

comment See what's filling up the server memory?
Your problem description is really vague. Why were you looking at the browser source code? Also a description like "went out of memory" is too vague to be useful. Virtual memory? Physical memory? Free RAM? Or what? Someone who understands your setup needs to troubleshoot.

comment DNAME Functionality Using CNAME
@AndrewB Cosmetics is about what you point to something, not about what you point something to. He wants to redirect the name they gave him to something else, which is a "what it goes to" thing, not a "what goes to it" thing. At least, that's how I read the question.

comment DNAME Functionality Using CNAME
Your question doesn't make sense. They gave you something that links to the teamspeak server. Why would you want to make it link to something else? And if so, what?
