comment Puppet-dashboard with two CAs
Lots of "supposed to" and "how could it" in your comments and question and very light on details like configs and stacktraces/network captures. Try using some network analysis, debugging, and process tracing tools to determine what's actually going on and show us you simply aren't mistaken about your config and environment behavior.

comment Why is my nginx load balancer misdirect phpMyAdmin after login?
Try developing against something that you'd use in production. You'll find that the products you write will have fewer integration and deployment problems.

comment Is an Ethernet point to point connection without a switch real time capable?
True. Most of the Devs visiting here kinda go glassy-eyed at this point.

comment Is an Ethernet point to point connection without a switch real time capable?
I assure you, collisions occur in twisted pair media as well. Your answer is worded quite poorly and may give inexperienced the impression that the elimination of collisions is inherent in the media, not simply due to the connection being built.

Coax has nothing to do with the collision. The important part is the buffering in the switch.

comment How to free linux memory safely to improve server performance
Nope, John. This is the best answer so far. I think you need to re-read the question and think about the output from 'free' that was posted.

comment How can I assign an IP by MAC address in dhcpd
That also truncates this fixed IP declaration, so this doesn't actually answer the OP's question.

comment What is using all of my memory on Ubuntu 12.04?
Top isn't going to tell you anything about why a particular process is using memory. And what are you doing with PHP that it's running as Root?

What I said in the first comment. Go read it.

comment scp to remote server permission denied
That's what I said. Adding group permissions is not correct.

comment scp to remote server permission denied
That's just masking the actual problem, not fixing it. The real problem is getting the correct owner settings on the other account.

comment Not running a cron job when the prev run was not finished
Better yet is to wrap the first letter of the grep search term in square braces, such as 'ps ax | grep [f]oobar'. The process list will duplicate the braces, but will filter out on the grep as not matching the regex.

comment Replacing Hard Drives
This is not entirely true. if a large number of your disks are from the same lot, you run a much higher risk of simultaneous failure when you add the stress of a rebuild. As noted in another answer, increasing sizes ofRAID5 run increasing probabilities of a URE during rebuild which takes your array below the raid5 validity threshold.

at least it produced upvotes for the questions that aren't pure idiocy.

comment Find out ESXi host from VM?
@KyleBrandt Your question as posted is short on details that would indicate what research has been done, what methods you've already tried that didn't work, or any troubleshooting steps. Frankly, if this were coming from a low-rep account, I think it would already have a close vote or two.

comment Comcast Business Gatway cg3000dcr kills VPN connections after about 3mb of transfer
Just buy a proper WAN router and put your Comcast box in bridged mode to use it as a L1 media converter. Seriously, the old "crappy" FVS3xx Netgear stuff worked better than most of the trash from the ISPs does now. And my Pro-sumer Buffalo router with DD-WRT even support advanced concepts like VLAN tagging. You do know about the backdoors that ISPs put in their routers, right?

comment Iptables config breaks Java + Elastic Search communication
Set up a jump target for logging to determine the characteristics of the connection being dropped. Otherwise you're just guessing and poking at it blindly. serverfault.com/a/446809/73435

comment trying to connect to non-standard port over esxi guest network
I know you said "firewalls are down", but that's not exactly a precise statement. How about the output of from the RH box: sudo iptables -L -nv

comment Beginner server local installation
@TomTom Indeed. Even though the cost of getting a small business plan for Office365 or GoogleApps is negligible when compared to operating the rest of a business.

comment How do I access port 10,000 on AWS?
@Chloe Fresh install is irrelevant to whether it works or not. It's broken. You've broken it in some fashion, or you picked a bad AMI out of the list at AWS. Now you need to fix it.
