comment 32 core (each physical core) 2.2 GhZ or 12 core (6 physical cores) 3.0GHZ?
@Matt Truth. Yet "tend to" is understated. I think even the low-end Intel i3 parts out-perform AMD parts on a MHz-for-MHz basis. Sad :( AMD's main selling point right now is the GPU, but that will change soon. But I digress...

@TejaswiRana updated. Matt of course you're right, and I alluded to such.

comment How to set up a software VPN when moving a server to the cloud
@womble These were EC2 server instances, which work much like Linode and everyone else doing Virtual Servers. If you read up on last weeks issue in particular, you'd see exactly what I'm talking about: informationweek.com/news/cloud-computing/infrastructure/… from the article: "...Okta built its Amazon-based service across more than one availability zone, and it didn't experience any downtime..." With AWS you have the capability of setting up EC2 servers in different zones. Many hosts don't offer this.

comment How to set up a software VPN when moving a server to the cloud
@womble Troll, you're missing the point. The idea (again, my opinion) is that the "cloud" is a place one should be able to place a server, data, etc. and have it be more available and more accessible than a traditional single-point-of-failure model. Who or what does it how is not the point at all.

comment How to set up a software VPN when moving a server to the cloud
@NealL VPC (virtual server instance) and OpenVPN are completely different concepts. You could easily install OpenVPN on a VPC. The question is whether the hosting provider will support it because of the special networking support required. Most do, but you should contact them first to confirm, just in case.

comment How to set up a software VPN when moving a server to the cloud
@womble My comments are an attempt to address the perception of the "cloud" vs traditional web hosting especially where reliability and uptime are concerned. AWS does have "cloud" services with their DynamoDB, RDS, EMR, S3, EBS etc. where your data or processing isn't fixed to any specific instance. Rather, it's spread across multiple servers in the "cloud".

comment How to set up a software VPN when moving a server to the cloud
@golja VPN is absolutely needed in a cloud environment, especially if the goal is to keep internal server resources off of the public internet, while still being able to access them as if they were on a local LAN.

comment How to set up a software VPN when moving a server to the cloud
@womble AWS could be considered a "cloud" in that it is a large set of servers (about 500,000 if some guesses are correct), upon which one could set up multiple instances of their own which meet my "description." I'm sure you could do the same thing with Linode or any other hosting company that exposes means of explicitly positioning virtual instances in different geographical datacenters or regions.

What error are you seeing? Does public_html have any content?

comment How to backup VirtualBox virtual server?
I thumbed down because I have determined that this is not a viable option as VirtualBox gets upgraded. For example I used this approach initially way back on version 2.x. Today with 4.1.x I was unable to boot instances I attempted to restore due to incompatibility in the config / xml files. Manual changes don't help. We haven't tested extensively yet, but exporting the VM as an Appliance is more / better likely to carry over the hardware configuration as well.

comment Centos running Hudson freezes, what logs to check to find out why?
Interesting and worth looking into. However, I'm curious if there is anything I can look at right now that might show me what is causing the crashing? (i.e. logging that's already taking place). Even if it is vague, it will give me a good place to start.

Looks very promising. We will try in the next day or so and check back to this thread to update.

Just regular 502 errors - nothing helpful otherwise. I think we're putting the "REquestHeader edit..." entry in the wrong place I just can't figure out where it belongs.

comment How to check if a port is open for remote system(ubuntu)
@user53864, that is correct. More specifically, it will list all OPEN ports and also describe what services are using them. If you are looking for a specific port, try simply "nmap example.com 22" as natxo asenjo said, which will scan port 22 (SSH) to see if it is open.

Exactly what I was thinking too. This is an answer for question 3. Ideal if you ask me :)

comment Batch file to uninstall all Sun Java versions?
Security would be the primary concern. Outdated versions of JVM have been very popularly exploited in recent attacks. Even Windows 7 machines were impacted.

comment Windows web server and SQL Server on same dedicated server
The best example of how latency can affect broader performance is by looking at an SSD vs mechanical hard drive performance-over-time comparison: techreport.com/articles.x/18712/8 If you look at the generic file copy performance (techreport.com/articles.x/18712/5), mechanical drives are on par with SSD's, but because SSD's virtually eliminate latency, they will blow mechanicals away in multi-write/access scenarios.

comment Windows web server and SQL Server on same dedicated server
The amount of data is not the problem, it is the time the .NET app spends waiting for a request / response. Network performance, especially in virtualized environements, is highly unpredictable and latencies can be very high. I'm speaking from direct experience with both small apps / databases as well as high-volume apps / large databases. If you can eliminate the variable, why not do so? Furthermore, if the database is small enough, it would be ideal to run the entire DB in memory rather than requiring any disc access at all. If it's a large DB, caching queries in RAM is preferred.
