OSSEC (Open Source SECurity)

OSSEC  (Open Source SECurity) is an host based intrusion detection system. Its primary function is to monitor Linux systems (files, configurations, rootkits, process monitoring) and alert to any changes. OSSEC is derived from TrendMicro, and the software can be found on enterprise systems monitoring critical hosts such as web servers, database backends etc.

Over flowing root

Document-1-page001Just the shortest article for the site:
Just as windows gives it’s users hours of fun running defrag, linux can fill it’s root partition with older versions of programmes if left unattended, mine got to 8.5gb (I use Chakra, which is Arch based so the commands used are Arch) and entirely filled the partition.(/var/cache being the culpit) Unlike windows however this is not really a problem till it gets to excess as it means you can reinstate any up graded programme if ‘progress’ is not to your liking. The answer is simple, if everything is running to your liking then the command ‘pacman -Scc’ (without the ‘ ‘) will wipe the lot. this is not recommended.
‘pacman -Sc’ will wipe all the older copies, but best of all the programme ‘paccache’ will give you total control over it all.
I am sure those of you far more learned than me will know the commands for Debain and other O/Ses.

Now I think this is fairly interesting but what makes it fun is with Linux you can open the root folder, go to /var/cache, open a terminal issue the commands and see your computer change before your eyes and followed by a general upgrade ‘pacman -Syu’ repopulating  the file.

Survey results of what members want from our Meetings

surveyresultsIt’s taken a while but I’ve collated the results of our survey relating to topics that our members would like to see at our meetings.

​You will see that there is quite an interest in Beginners topics, choice of Distro, interest in Virtualisation, Desktop and Raspberry Pi, and Programming. Topics such as Gaming on Linux, Business applications, such as CRM/ERP and Graphics faired less well. There were a few extra topics requested which you can also see listed, such as a Troubleshooting session (sounds a good one), outreach and spreadsheets for finance.

As discussed at the last LUG Meeting we plan the first meeting based around these topics in June 24th, 4th Wednesday of the month as usual, probably to allow time to get organised. What seemed like a good plan at the meeting is to have a Beginners session that also includes Distro choice, ie why I should choose Ubuntu over Debian, Fedora or Arch for example.

In the end we had 17 responses altogether not too bad, although people were allowed to vote for as many topics as they wanted which seemed like the fairest method to use.

I will setup a Pirate pad (or equivalent) online pad where we can share our plans for this first meeting. There wasn’t consensus where we should hire a room and and have a full session, or just keep things simple and carry on at the Courtyard but please say your ideas on this .

We will also need people who are happy to talk about topics for Beginners, and structure the event. I’m happy to help coordinate, but it’s always best to get as many volunteers to help to reduce the load for the others.

We will also of course need to plan what other events for each month we will hold based around the interest shown above.

So please reply and let everyone know your thoughts, plans and ideas and/or if you want to help

Manjaro Linux – a refreshing change … ?

Manjaro_logo_and_name_white_backgroundI’ve been using Linux for a long time, since 1998 As far as I recall and seen many changes and popular distros come and go. I started with Redhat 5.2 in a boxed setup which had a whole manual to help you install it ..

After Linux Mandrake pushed boundaries in usability , installation, and becoming the Ubuntu Linux before Ubuntu ever existed. Sadly Mandrake lost its way a little and died before being resurrected as Mandriva and recently coming back more strongly as Mageio.

Instead I moved to Ubuntu on the second ever release back as Warty Warthrog, 4.10 , after always wanting an easy to use stable distro, that had the Debian base or upgrades far better than that offered by rpm based distros at the time.  I stuck with Ubuntu a long while, and stuck with Unity, but just found it wasn’t ideal for a work distro, but great for an absolute newcomers linux.

I moved to Linux Mint, which I still use at home, and like a lot apart from two things:

  1.  The change to only updating most packages far less frequently (In prefer to add ppa’s and get newer packages for a number of applications
  2.  I found that Cinnamon although a great Desktop, I still love, is just a bit  ……………………. slow …

I’d heard about the ‘Rolling release ‘ distros such as Arch and a few other flavours but they didn’t quite fit, or in Arch’s case, very interesting , blisteringly quick, but needing quite a bit of time to get setup and dangers in instability just when you don’t want them

I instead looked for an Arch clone as I like ‘the Arch way’, but preferred a slightly different route. There are others, but I preferred a non KDE distro which ruled out a couple of options and found myself downloading and trying out Manjaro off a Linux format disc in a VM. I was impressed ! So fast even in Live mode. packages far newer than in most distros without endless ppas required.  I tried the standard Manjaro iso first with XFCE, which I hadn’t tried for a few years but found it had really come on leaps and bounds and was missing very few touches that I had with cinnaman as part of Mint. For that matter there are community build versions of Manjaro with Cinnamon so you can have your cake and it. But so far I’ve stuck with the XFCe version, which is so fast, its like adding another couple of CPU’s to your pc.

Its still early days and I hope I don’t find any breakages which has happened to others on odd occasions, but as being a non newbie I can usually fix most systems if required.

There si a new major version coming up shortly 0.90 currently in prerelease 5 , which promises a lot, but as a rolling release I have it already, with my upgraded 0.8.12 version I installed a while back.

But don’t take my word for it , give it a try yourself … nothing to lose.

Inkscape Review

calligraphy-f10-en.svgpath3335I’ve never used a CAD program, or Adobe Illustrator, always got by with Photoshop and then Gimp, but now at last I’m going to learn Inkscape for some drawings of plans for my house. Maybe then when I can handle two dimensions I’ll have another look at Blender !

Its easily downloaded from https://inkscape.org/

Help is included and works from the menus first time.

Help> Tutorials gives eight Inkscape documents which are tutorials, and which you can edit yourself (but don’t save), drag the shapes around and get a feel for how it works. Basic, Shapes, Advanced, Tracing, Calligraphy, Interpolate, Elements of Design, Tips and Tricks. I did some a few nights ago, done another two tonight. The Calligraphy one is interesting, I skimmed it, but I don’t think I’ll ever use it.

Super.

ToriOS

torios logo http://torios.net/

A minimal Ubuntu-ish installation which also works on most older machines

I have discovered that Lubuntu does not work on older machines, as it need a PAE CPU

I have been recommended to use ToriOS as a non-PAE capable spin-off from Ubuntu.

http://torios.org/ is the original website, but they’ve lost access to update it so are making a new website at http://torios.net/

It looks like this project needs more workers on it !

In an email replying to my question of why their forum doesn’t work they wrote:

we have decided to put the forums off until we release the
stable version and have people who could take care of the forum. For now, we don’t need it.

Other small linuxes are Damn Small Linux and Slitaz.

Router Story

I recently installed DD-WRT on my router.  It is an open source firmware that gets more out of the router, I specifically did it as TalkTalk, who are my ISP, now provide a few Internet streaming TV channels via the YouView service which stopped working  when I ditched the router (Huawei HG 533) they supplied in place for a fairly cheap Netgear WNR2000v2. The Netgear seems to handle DNS better and surfing the Web is now an a lot more pleasurable experience.  These Internet TV channels not working did annoy me a bit though, I found out it was due to the Firewall in the router blocking Multicast ‘signals’.  There was no way to remedy this using stock firmware but installing DD-WRT gave me a lot more options and it was very easy to enable Multicast.
