Configure Local and Remote System Logging : Ubuntu

Filed under
HowTos

A linux machine has a logging system which keeps track of what everything is doing. Anytime you authorize with sudo it gets logged. Anytime you (or someone else) connects via ssh it gets logged. Apache logs connections, mail servers log emails sent and refused. Pretty much everything keeps a log of what it is doing so you can later troubleshoot it or simply have a record of it.For those that are security minded it may not be a bad idea to keep duplicate of your logs by sending them not only to the local machine but to a remote machine as well. This way, even if an attacker is able to get into the first machine his steps are logged remotely before he is able to clear them on the local machine. This, of course, has a number of other valuable uses. In any event, here are a few quick steps to set it up.

/etc/syslog.conf

This file is the main “what gets logged and where” file for your system. If you take a look at it you’ll see that it takes different types of logs and writes them to the appropriate files. Mail here. Cron there. etc. We can easily tell the system to send the logs elsewhere with the following:

Android Leftovers

  • OnePlus Will Reveal Details Of Its ‘Oxygen’ Android ROM On February 12
    OnePlus introduced its own version of Android for its One smartphone earlier this month in response to its standoff with Cyanogen, and now the company has revealed that it will unveil its own ROM which can be installed on third-party Android devices on February 12. Correction: OnePlus tells us that, in fact, it won’t launch the ROM on the 12th. This is a tease-of-a-tease, and instead we can expect to see “more information about the ROM” not an actual download for third-party Android devices.
  • Android is suddenly surrounded by enemies
    Cyanogen is one of these forks. It has just raised $70 million from a number of investors including Microsoft to continue producing its own version of Android that it can position as a direct competitor to Google's.

    You might want to think twice before sending that sensitive text message over your supposedly secure Blackphone. A security flaw discovered by an Australian communication security expert could have allowed attackers to decrypt a Blackphone user’s messages, gather location information, and run additional code of the attacker’s choosing.
  • World’s most ‘NSA-proof’ phone vulnerable to simple SMS hack
    A smartphone marketed as the most anti-surveillance, NSA-proof personal device – the BlackPhone – has been found vulnerable to a simple SMS attack that allows the hacker to steal contacts, decrypt messages, and even take full control of the device.

Ubuntu vs. Fedora Linux On Lenovo's X1 Carbon With Core i7 Broadwell

The latest distribution I tried on the X1 Carbon (and the OS I'll ultimately use for running the X1 Carbon in a production capacity as my main system) is Fedora 21. Fedora 21 booted up on the X1 Carbon wonderfully without any issues aside from the trackpoint button clicks being wonky (though the button clicks in the corner of the trackpad works fine). Fedora 21 with Wayland also ran fine on this system with Intel HD Graphics 5500. Overall, it was a pleasant experience without any major problems. Read more
