Never seen a webanalytics software like Woopra before.

Tuesday, May 20th, 2008 | Permalink

First of all I have to give the guys from woopra two thumbs up.
I use webanalytics software for some years now. I worked with Indextools and like nearly everyone with Google Analytics.
As Indextools has been sold to Yahoo, Yahoo decided to change the business model of Indextools.
Indextools was not free of charge and hugh application for small sites. So Indextools is more a enterprise tracking system.

Google Analytics is free of charge. On big problem for commercial sites is that the collected data is owned by Google and the “terms and conditions” can be change quickly to use these data for their own needs.

Okay back to the main topic. A friend of mine told me about Woopra and I decided to sign up for the beta test. Woopra is free of charge right now. After the signup you’ll have to wait until the guys from Woopra decided to give you access. In my case, this took two weeks.
After you’re enabled for Woopra, you have to install a javascript in your website.
The cool thing behind Woopra is the Java application you can download from their page. Sadly you’ll need java 1.6 which kicks out nearly all the Mac OS X guys, because Java 1.6 is only availible to 64bit users, which means only Mac Pro users are supported.
After installing the java application you have a wonderful, flash look-like, interface.

The best thing, you can see your users in real time. You can see, which site they are looking at, how long they have been there, where they came from (website and city/country) and a lot more.
The killer feature here is that woopra enables you to chat to current visitors on your website.
You can choose a user, click on “talk to this user” and get a chat window to talk to them.

At the end, Woopra is nice for small sites and blogs. I guess big business sites will not get the data they need and should use things like Indextools.

Btw. I think Woopra ROCKS!

How to fix “transfer aborted. disk quota exceeded” –

Friday, January 11th, 2008 | Permalink

If you try to upload something you get “transfer aborted. disk quota exceeded”.

If you bought a webhosting package somewhere, the answer is simple: “You don’t have anymore space left”.
If this happens before the quota is exceeded and you have a root access to that machine, simple use this:

quotacheck -v -c -F vfsold -m /

and restart the quota daemon

/etc/init.d/quota restart

Howto install djbdns with autoaxfr

Saturday, January 5th, 2008 | Permalink

If you like to setup autoaxfr with djbdns, maybe this howto will help you.

First of all, I assume that you have already installed ucspi-tcp and daemontools. If not, look at D.J. Bernsteins Webseite and install it.

After that, you will have to download autoaxfr and the djbdns Package.
What I’m doing is a basic installation. If you need IPv6 support, watch out, there will be a patch somewhere for djbdns.

Now, add the necessary users:

groupadd dns
useradd -g dns -s /bin/false dnscache
useradd -g dns -s /bin/false tinydns
useradd -g dns -s /bin/false dnslog
useradd -g dns -s /bin/false axfrdns
useradd -g dns -s /bin/false autoaxfr


First of all, we install dnscache to

dnscache-conf dnscache dnslog /etc/dnscache
If you like to distribute dns service to other machines in your network, add a real ip address.
WARNING: You can only use dnscache or tinydns on ONE ip address.

If you need dnscache to resolv domain names for other machines in your network, add the network or every machine by doing this.
touch /etc/dnscache/root/ip/192.168.0

Now it’s time to activate your dnscache.
ln -s /etc/dnscache /service


You will need tinydns if you like to play dns server for domains.
First of all, configure it:
tinydns-conf tinydns dnslog /etc/tinydns
Use the external ip address, the server should be reachable at.

Now it’s time to setup autoaxfr.
autoaxfr-conf autoaxfr dnslog /etc/autoaxfr

You will now have to edit the file /etc/tinydns/root/Makefile
Replace everything with this:
data.cdb: data

data: mydata axfrdata
cat $^ > $@

axfrdata: /service/autoaxfr/root/zones/*
sort -u $^ > $@

Don’t forget to add the file mydata & axfrdata:

touch /etc/tinydns/root/axfrdata
touch /etc/tinydns/root/mydata

After every change of data, a secondary dns or whatever, you’ll have to type make in /etc/tinydns/root/
Just automate this with a cronjob.

*/10 * * * * cd /etc/tinydns/root && make > /dev/null 2>&1

Let’s start tinydns and autoaxfr.

ln -s /etc/tinydns /service
ln -s /etc/autoaxfr /service

Goto /etc/autoaxfr/root/slaves.
Add every domain you would like to distribute as secondary dns by adding the domain name as filename and the ip address of the primary dns controller as content in the file.


DONE! That’s the basic.

If you like to play primary dns server you’ll have to install axfrdns.
axfrdns-conf axfrdns dnslog /etc/axfrdns /etc/tinydns
Use the same ip address as for tinydns.

Set the servers that are allowed to be secondary dns servers.
cd /etc/axfrdns
vi /etc/axfrdns/tcp

insert to following.

You can restrict that to networks, domains and so on. For that, see the axfrdns manuel from djb.

After you have changed the file, type make.

Start axfrdns.

ln -s /etc/axfrdns /service

Comments, questions, whatever are welcome.
