Network connection problem in windows 7

I had been having problems with windows 7 as it was taking so much time to connect to the network(upto 15 mins…way more than what it used to be). So I finally made up my lazy mind to see whats wrong. I ran the troubleshoot test on the network connections but it didn’t solve the problem. I noticed the following

Diagnostics policy service is not running. After some googling I found out that system restore could solve the issue..nope that’s not possible any alternatives ????

Finally from a forum I found out that removing all the network adapters and then rebooting the system will solve the problem. If by mistake you remove the network drivers you will have to reinstall it. 

Luckily the above method solved my problem. The network adapters got created again after I rebooted and things were happy and all good again. Hope it helps!!!!

A great GUI for keytool-keytool-iui

I had always used the command line arguments while creating the keystores, creating self signed certificates, importing the trusted certificates till yesterday when I thought enough is enough and started googling for “best gui keytool”. Options came up and I found this beauty I should say, the work of some “smart person”. Now there is no more complaining about using keytool. Here is a video which explains how to use it.

Useful book on linux commands

Being a daily user of linux, I can always find my way out but sometimes remembering the commands with arguments is quite difficult. Ofcourse there is google but nothing helps like a command book or a cheat sheet. Came across this book which always works out for me. Searching for keywords in this book just works out for me.

I have been using wireshark lately in my project. With a lot of issues coming up on the firewall port openings wireshark is a very useful software which can avoid hours of wastage. Came across a blog which has used wireshark wisely.

Using Jarscan

Did you know there’s a tool that can help you search through JAR files to find Java classes or packages? I’ve been using it for years and I am often surprised that so few Java developers have it in their toolbox. Of course, it’s very handy for resolving those pesky NoClassDefFoundError and ClassNotFoundExceptions, but my favorite use case is to find the location of a class and JAR file on my hard-drive so I can decompile it to understand what some vendor’s proprietary code is actually doing behind the scenes. I know vendors frown on this, but whatever; I’ve got a job to do.

The tool is called jarscan and you can read more about it or download it here.

It’s just a little jar file that executes as a command-line program. On my Windows virtual machines, I put the jar file in C:\JarScanner\

If you’d like to find a Java class called “SystemProperty” somewhere in the “C:\IBM\WebSphere\PortalServer” directory. You would execute the following command:

java -jar C:\JarScanner\jarscan.jar -dir c:\IBM\WebSphere\PortalServer -class SystemProperty

That command would then search through every jar file that it can find in the PortalServer directory, including sub-directories. If it finds the specified class file, it reports the location and name of the Jar file containing the class. You can also search for packages, not just class files.

For Help, type the following command:

java -jar C:\JarScanner\jarscan.jar -help

How to change port numbers in freeradius

The port numbers for freeradius is configured in the file radiusd.conf. Leaving it as 0 will pick the ports for auth and acct from /etc/services. I guess the values would be 1645/1646. You can manually set the values to 1812 and 1813 as shown in the below screenshots and restart the freeradius server. It just works!!
