tmux – terminal multiplexer

tmux is a terminal multiplexer: it enables a number of terminals to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.

When tmux is started it creates a new session with a single window and displays it on screen. A status line at the bottom of the screen shows information on the current session and is used to enter interactive commands.

How to install Icinga (Nagios Fork) in Ubuntu 12.10 server

Icinga is an enterprise grade open source monitoring system which keeps watch over networks and any conceivable network resource, notifies the user of errors and recoveries and generates performance data for reporting. Scalable and extensible, Icinga can monitor complex, large environments across dispersed locations.

Icinga is a fork of Nagios and is backward compatible. So, Nagios configurations, plugins and addons can all be used with Icinga. Though Icinga retains all the existing features of its predecessor, it builds on them to add many long awaited patches and features requested by the user community.

task-spooler – Personal job scheduler

task spooler is a Unix batch system where the tasks spooled run one after the other. The amount of jobs to run at once can be set at any time. Each user in each system has his own job queue. The tasks are run in the correct context (that of enqueue) from any shell/process, and its output/results can be easily watched. It is very useful when you know that your commands depend on a lot of RAM, a lot of disk use, give a lot of output, or for whatever reason it's better not to run them all at the same time, while you want to keep your resources busy for maximum benfit. Its interface allows using it easily in scripts.

Please report this bug against the 'update-manager' package and include the following error message:

'E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_precise-security_main_i18n_Translation-en, E:The package lists or status file could not be parsed or opened.'

Ubuntu feels like it is falling apart!

Since the introduction of Unity I've had nothing but trouble. Unity is awful but replacing it with Gnome is not easy or a sure bet; apport keeps crashing but only occasionally causes a lockup; GRUB is a mess; Samba doesn't work most of the time. What the heck is going on?

I've been using Ubuntu since ~ V.4.x and have always loved it, but now it doesn't seem to want to live up to its own high standards. Something is very wrong and I'd appreciate it if someone would explain what is going on.

I'm using 12.04 on this laptop but Gnome is a mess. I've switched to LinuxMint for my new desktop because Ubuntu is too unstable. How a derivative distro can be more stable than its parent is a mystery to me, but it is. Of course Mint isn't very good with wireless so I can't switch my laptop.

OK. Enough ranting. Just please tell me what is going on?

sslh – ssl/ssh multiplexer

sslh accepts connections on specified ports, and forwards them further based on tests performed on the first data packet sent by the remote client.Probes for HTTP, SSL, SSH, OpenVPN, tinc, XMPP are implemented, and any other protocol that can be tested using a regular expression, can be recognised. A typical use case is to allow serving several services on port 443 (e.g. to connect to ssh from inside a corporate firewall, which almost never block port 443) while still serving HTTPS on that port.
