Did someone say ‘subversion’
Sunday, December 25th, 2005 |So you’re using cvs (me too), and is bitching about how anoying/difficult it is to control access, etc….
So someone told me; “oh, you have to look at subversion”, which I did, and man was I in for a surprise – not only is it cool, but it is almost as anoying as it is cool.
First forget about running the subversion server, it stinks major… Do it with apache (2.0.xx), and then it works. Make sure that you read the documentation, again, probably more than 3 times just to make sure.
Oh, do not have more than one project per repository, that will mess up your revisions, which means that you have to setup a repository for each project, but that also means that you can control access per project, which is another cool thing, and at the same time very anoying.
Oh, forget about bugzilla, and viewcvs, etc. have a look at trac which does most of what bugzilla does, and a bit more. But as usual, the installation stinks, and the documentation is something you can wish for (or am I being stupid?).
And no I’ve only gotten to the point where I’m trying to figure out how things work…..
Linksys NSLU2
Sunday, December 25th, 2005 |I’ve been having a box standing in a corner for years, which have been running my webserver (yes, this), my mail server, and my file server. It’s a hungry beast, ie. it’s a Intel P4, with lots of RAM, and more harddrives than I can think of (or wish to think of).
As I was not able to find my christmas present (Nikon D200 or Apple 15″ Powerbook (int. english keyboard was the problem)), I decided to spend a bit of money on a few other things;; like a new harddrive, and a Linksys NSLU2 which in the first place might look a bit borring, but it’s quite cool, and an external USB harddrive.
It have a few good things about it;
- runs linux
- runs linux
- runs linux
Which means that there are some very nice people out there who have figured out how to do very interesting things with it, like hack the firmware so that it is possible to install more programs on it. The coolest thing around is mt-daapd which is an opensource iTunes server running on almost any platform.
So after a bit of searching, I found home page of the deciated geeks; www.nslu2-linux.org, got the latest version UnSlug, got it installed an bingo it worked. Then I followed the readme to ‘unsling’ (boot of a USB harddrive instead of the internal flash disk). Then I used ‘ipkg update’, ‘ipkg install mt-daapd’, modified the configuration file, and bingo I had my iTunes server running.
And it still works, I haven’t broken anything (yet).
Now, earlier this month I switched ISP, which ment going from a routed connection to a bridged connection, which ment that I had to setup another PC to work as a router… The NSLU2 works with some USB Network Cards, what if……..
Another desktop blogging tool
Saturday, November 5th, 2005 |So after getting a way of blogging directly from the desktop from Linux, next step was to find a way to do it from Apple OSX. And yes there is a widget which will do blogging to wordpress.
Download RapidMetaBlog and point it to http://you.url.domain/path/xmlrpc.php type in your username and password, and it works.
How difficult can that be.
Software actually works sometimes….
Friday, November 4th, 2005 |I was playing around with my PC at work, and saw that in Gnome there is an ‘Blog Entry Poster’ applet, which can post entries to blogs…
Great now I no longer need to login to my blog to post entries.
sshd – Invalid user ….
Monday, September 5th, 2005 |I’ve written a couple of entries about my anoyance and solving the issue with "Invalid user", after I started running my script it seams that there are 40 ipaddress which actually is causing this.
If you want to get ridge of this, then either run my script block_idiots_ssh.pl, or start by blocking the following ipaddresses:
136.201.107.1
137.99.10.239
165.138.251.222
195.167.202.196
198.104.137.241
200.62.142.213
202.222.18.60
202.64.210.245
203.86.84.113
210.230.64.24
210.73.128.152
211.189.26.30
211.21.128.186
211.45.120.112
211.75.4.188
213.146.166.240
213.80.105.8
213.93.189.51
216.20.244.22
217.160.170.220
218.37.89.50
218.41.93.138
219.140.167.51
220.130.245.91
220.95.232.114
220.95.232.216
222.208.171.133
24.202.99.204
24.4.255.24
59.120.171.146
61.195.159.211
61.246.1.251
62.108.199.156
62.141.35.40
69.211.157.105
69.50.225.230
80.23.97.194
80.28.216.105
82.224.162.170
83.220.130.10
By using iptables: # iptables -A INPUT -i <interface> -s IPADDRESS -p tcp –dport 22 -j DROP
Then you should hopefully see that you number of "Invalid user" entries in /var/log/secure will go down. If not start doing something active.
Howto block scripts kiddie’s
Thursday, August 18th, 2005 |So you probably have the same issue as I do – you see ‘[sshd] … Invalid user … ‘, a couple of hundred times a day. And would like to stop that, well you could write a script which scannes the /var/log/secure every couple of seconds, or you could do as I did.
First I figured out how to read from syslog in realtime. Next came the big one, how to make the whole thing work. Well I knew that my pipe was working, and the daemon thing – well it was running, but howto make it work. After some hours the result is actually working, and I only see one entry in my secure syslog per attempt to break in, and also only one entry in iptables (timing is the issue here).
If you’re interested in the code download it block_idiots_ssh.pl
It should be self explaining, otherwise use www.google.com to find out what it does (there are some pretty good perl sites out there) – not the most pretty perl code ever produced, but hey it is working.
