I’ve spent the last two days listening to podcast after podcast describing the technical details of the computer programming flaw that allows attackers slurp unprotected memory from websites, Tor nodes, and IMAP email servers. Thousands of websites have patched their web servers but millions more email and web servers are going to be slow to patch their services.
Go install Lastpass. Use it’s Security Report feature. Create new passwords for sites that have fixed themselves against the Heartbleed bug.

Here’s a rough idea for some CR100 mug art.
This says it all.
I am refurbishing my ZFS on Linux backup box. It is an Asus/A2 motherboard chipset and runs slow but happily on two 3 four port sata controllers in a addition to all its server onboard sata ports. One of those sata crontrollers is on the PCI slot which will never run as fast. I can measure the difference watching the drives in iostat.
I picked up a likely pair of 8-port SAS controllers off ebay thinking I could get some PCIe-x8 action going. Unfortunately, I had to learn my lessons about LSI Megaraid, the MegaSAS 2008 controller… What a farce! These cards only want to run in HW raid mode and they entirely block bootup by obscuring the onboard SATA controller. (Who wants them?)
But clearly, I need some advice on a good JBOD HBA, or a raid card that won’t kill the budget. Is the SuperMicro AOP controller going to be a better choice? http://tinyurl.com/ohcy5t4 ? Or will Dell PERC H310 controllers http://tinyurl.com/pncuuem do the job?
I don’t want to reformat the drives of course, I would just like them to run consistently faster.
I use all of these tricks when setting up my own ssh servers.

However when it comes to work with SFTP o GIT it might become annoying. Everytime you sFTP upload or git push you have to wait 30 seconds again.
This kind of problems are often related to DNS issues but this is not always the case. Following are the most common solutions:
1. Disable reverse IP resolution on SSH server
It turns out there is a setting in OpenSSH that controls whether SSHd should not only resolve remote host names but also check whether the resolved host names map back to remote…

This is a great pile of advice on creating virtual network interfaces.
Always good to have a nice reminder on how to configure a DNS service!
