This is only really necessary in the case you don't want DHCP. If you are dealing with an encrypted LUKS server on the internet, you will often want to have a static IP so you know which IP to connect to (or if you have a semi-static IP assigned by DHCP).

This is a VIA made VL805 USB 3.0 Chipset with 4-ports and MOLEX powered. First of all this unit was cheap at about only 9 USD with fast shipping. My biggest concern was if this was a quality unit and would it really give you full USB 3.0 speeds (some people reported with similar cards that for some weird r........

Why won't my Linux Mint boot after I manually installed a new kernel? eg. apt-get install linux-image-newerone Do this dpkg -l|grep linux-image|grep extra ii linux-image-extra-3.16.0-38-generic 3.16.0-38.52~14.04.1&nb........

*Update so this doesn't work it must be something to do with the path of nfs or something else but the installer fails with "Installer crashed" at the end whereas with the CD/USB it works. This assumes you've already installed and configured a separate PXE/DHCP server somewhere else and your /tftpboot directory is setup. This is for Linux Mint 18.1 but generally applies to most versions although you may have tro change things like "casper"........

sed gets to be a pain and a real mess and is hard to read and understand when you have to escape things like / etc. Idid not realize until recently that you don't need to use / as a separator, you can use virtually any non letter or number character. Eg we have used # as the separator to avoid having to escape the forward slashes and in this way the command is plain, easy to understand, edit and saves time/hassle without the need for escaping. sed -i s#http........

Example: basename /var/log/messages messages As shown above the "basename" utility gives you the end filename separately. dirname /var/log/messages /var/log As shown above the "dirname" utlity gives you just the utility even if you pass it a specific file. The above two utilities are very helpful in Bash scripting when working with files and directories co........

This is a great way to use your ftp server space, for example on your web hosting account (althoughI believe many hosts don't allow storage like this), but if you have a VPS/Dedicated Server etc.., this would be perfect. Imagine how easy it is to work with an ftp account that you can just mount as a normal partition or directory in Linux, it would be great for backups etc..

Asterisk Agent Login ProblemUsing the AgentCallbackLogin function I couldn't login I knew I had my agents setup properly in agents.conf so why couldn't I login? The reason is because agents.conf was missing the [b:994d7a34af][agents][/b:994d7a34af] context! I just added [agents] above the existing agent declarations and then I was able to login as expected. It took a lot of figuring out and reading though!........
