Zerobin service is updated to version 0.19.
As a reminder for those wondering what is this:
ZeroBin is a minimalist, opensource online pastebin/discussion board where the server has zero knowledge of hosted data. Data is encrypted/decrypted in the browser using 256 bits AES.
Here are the updates from previous version (0.18)
- Corrected XSS security flaw which affected IE<10. Other browsers were not affected.
- Corrected spacing display in IE<10.

Mute Screamer uses PHPIDS to detect attacks on your WordPress site and react in a way that you choose.
If you have too many intrusions in you Mute Screamer log (v 1.0.7 at time of writing) removing them via Admin (web) interface could be time consuming.
Faster is to do that directly on the database.
Just execute this SQL command (MySQL in this example) on your WorPress database:
TRUNCATE TABLE 'PREFIX_mscr_intrusions'
NOTE: “mscr_intrusions” is default table name and PREFIX is your WordPress prefix you set on installation, please replace with correct value. if you do not have that table you can look for the name at line 53 in mute-screamer.php.
I will be glad to see clean all button in one of next versions.

Since version 2.0 of VLC a lot of changes were made in the code of this popular media player.
Something annoying was the increase of CPU usage when playing audio files. From almost 0% to 10-20%.
On powerful system this increase is almost unnoticeable, but on Intel Atom or AMD C60 you can notice the difference.
The fix is really easy.
Shutdown VLC and just erase/rename following 2 files from VLC folder (in my case C:\Program Files (x86)\VideoLAN\VLC\plugins\codec):
- libsamplerate_plugin.dll
- libspeex_resampler_plugin.dll
And this is all. CPU usage is back to normal.
I did not notice any problems for now.
Finally I can use again VLC on all my systems.

Adding few DNS records from GUI is a breeze, but when you have more than one some automation will help.
Windows provides command line tools to help you with that.
But the trick is that you have to get your hands “dirty” and type some commands in bat file.
In this case I’m using dnscmd tool (from Windows Support Tools).
If you are unsure how to install it check Install Windows Support Tools tutorial from Microsoft
Here is dns.bat:
@echo off
set dnshost=localhost
set domain=
echo “We are reading records from records.txt”
for /F “tokens=1,2,3 delims=,” %%G in (records.txt) do dnscmd %dnshost% /RecordAdd %domain% %%G %%H %%I
It reads records from records.txt formatted in following way:
<hostname>,<record type>,<IP>
First record is hostname (without domain) followed by record type (A, PTR…) and last ip addres
NOTE: there is comma separating all values
How to use it:
1. Put your records in records.txt
2. type dns.bat
3. That it is… (Probably good time to validate 🙂 )

Since version 19 Mozilla Firefox comes with build in PDF viewer.
Generally it does the work and it is really useful when no another PDF reader is installed, but in some cases is not so appropriate and you might be better with external viewer.
Problem I have is that it is Java Script based and even JS is really fast on low power machines it is not as fast as “real” plugin.
In case you need to disable build in viewer do following:
- Open Firefox Options
- Go to Applications
- Find PDF in the list and change the action from Preview in Firefox to appropriate one.
That is all…

How to restore HTTP to address bar
Filed Under Howto | Leave a Comment
Mozilla constantly improves Firefox. Some improvements are good, but some questionable or it is just personal preference.
One of the things developers changed in recent versions is the way website URL is displayed in address bar.
Now it looks like this:
as you can see http:// protocol in front of URL is hidden
But I prefer to be shown like that
Now I know that I’m visiting http site 😉
From one side it leaves only web address and it is less crowded, but if you feel uncomfortable without http just follow these steps:
- Type in Firefox address bar about:config
- Filter to browser.urlbar.trimURLs (just copy/paste in Filter field)
- Double click on result listing or choose toggle from context menu. Value should be set to false – this disables URL trimming.
- That is it – now you have http:// if front of your URL.
- If you prefer to go back to default value just repeat the procedure and be sure that value is true.
- This will re enable URL trimming.

Protect SSH logins
Filed Under Linux | Leave a Comment
SSH short for Secure SHell is cryptographic network protocol. It is widely used in UNIX/Linux(but not limited to) world to allow clients to securely connect to a server. It is replacing older and insecure protocols like rsh and telnet. In addition to security it add tunneling for other protocols.
And since it is widely used it is often exploited to get unauthorized access to the system.
Enough general information. Back to the topic.
There are few simple rules on how to protect:
- If you do not need it do not enable it
- Restrict access
- Change listening port
- Use version 2 (if possible)
- Disallow root access
- Use strong passwords
- Block access
- Use key authentication
- Use “One time passwords”
- Show Warning message
