Multi line pattern match with fail2ban
I run my own asterisk server where it is well protected against external attacks using iptables + fail2ban. I thought it was secure enough until I came across attacks which my current fail2ban configuration failed to detect. In investigation tells me that fail2ban cannot do multi line pattern match and because the attacker’s IP was not logged in the same line where the attack statement was mentioned, fail2ban did not work.
The only solution I could find / think of is to write my own script which will write these multiple lines into one single line. Assuming you will hit this bottleneck of fail2ban sooner or later, I have uploaded the script which I wrote to github and available for free download.
Feel free to use the script. I welcome your comments / suggestions.

Deploy to GAE not working
I was trying to deploy my new version of GAE to app engine. It took some time before I figured out why my deployed site was not showing live. What I did new while deploying the new version is that I changed the version from 1 to 2. After changing the version, though it was deployed successfully, the app engine continued to use my version 1 as the default instance.
To change the default instance to 2, do the following:
- Log into to appengine.google.com using your login credentials
- Select your app. This should launch the app dashboard.
- In the left sidebar, select Versions.
- Here it should list both the version.
- Select version 2 and set as default.
You are done. Now your newly deployed version should be visible live.
