This is just another way to do it: an adware/spyware free /etc/hosts for your laptop or home network.

Lately I was asked to develop and integrate a realtime server disk usage graph to the dashboard of our monitoring application (OpenNMS). The bar graph color should also change when disk usage exceeds a defined  percentage threshold.

… or “confine untrusted users to their home directory (and give them no shell access as well)”

So you’ve setup your company secured internal Debian APT repository server by allowing apt operations only via SSH with prior public key exchange. Great.

I have several virtual linux guests running on VirtualBox: a bunch of test machines to which I connect exclusively via ssh from my host terminal.

If you have to assign strong passwords and you are in a lack of creativity, you may try to accomplish the task in many ways (for example by doing some rude redirect of /dev/urandom)

On last post I showed how to setup a long list timestamped bash history. In the last two months I had the opportunity to work on a set of FreeBSD (version 8) servers that come with CSH as default shell.

One of the first thing I do after installing Linux on a server is setting up the bash history to show the timestamp along with the command issued.

Today I’d like to put into my notes the config I use in order to customize the bash shell prompt. This is with no doubt an extra, probably you’ll never need this.. until the day you realize that working on several remote systems at the same time can be confusing, and confusion leads to mistakes.
