Keeping the default 22 SSH port is really a very bad practice. I have seen many people doesnt bother changing their SSH port even they configure many security features.
In this short and sweet guide Im going to tell you how to change your SSH port to another. This guide applies for Ubuntu/Debian/Centos/Redhat O/S
Attention- Messing with others things on SSH config file is really dangerous and it may lock your server from accessing via SSH. So you will need console access to reset SSH or contact server provider to do this. So forward with your own risk!

Have you ever worried about your government,workplace,school or ISP limitations for web sites? Are you behind Great firewall of china? are you worried about browsing speeds with overloaded or slow web proxy services?
HTTP proxies are the best solution for you. And with squid cache you can make a nice HTTP proxy for your personal or family use.
In my case I have tried SSH SOCKS5 method for access blocked sites but I feel it too slow because connection is encrypted but its so secure than HTTP proxy.
But I don’t need much security like SOCKS5 offer So I have decided to setup squid as a proxy server for my personal use. And felt that its delivering blazing fast speed as same as I’m browsing without proxies.
So now all my firefox traffic is going through HTTP Squid proxy running on UK 512MB XEN box that I had spare and I don’t thinking about going back to normal no proxy mode because speed is same as no proxy.
So here is my guide to setup squid as a proxy server on ubuntu or debian for you!

Skype had major downtime for last 24-48 hours for more over 90% of their users including me! Well it was started 24 hours ago for me. My skype was freezing out about every 5 minutes and then it begun to log me out. I thought hey this might be problem in my computer like my firewall is blocking skype port or something and I restarted my computer. But it didn’t fixed keeps me failure to log in displaying connecting message.
Again I thought there might be problem in my skype software then I uninstalled it and installed again to see what happens. No luck when skype was blacking out I was in chat and I emailed my partners that I got a problem in my skype and Ill talk with them later. Damn my mind never pointed me out that if there is problem with skype they will report it on their twitter feed www.twitter.com/skype **bangs head**
Today morning I found that some other users complaining about this problem and I have searched twitter about this.
Skype didn’t supplied detailed causes about what happened rather that telling their “Supernodes” down because of some software problem and some unofficial discussions going that wikileaks haters attacked skype because Julian Assange was interviewed on skype :X
So at the time of writing skype is online for most of us and for me it took exactly 24 hours to get back online!
Lets see how trend moves on!

Its really cool thing to track your online visitors live (how many visitors online at the moment and what they are browsing) for me it force me to blog more! Some web statistic programs like sitemeter can be used to do this trick but they not most accurate because its cookie based tracking!
For wordpress there is a nice plugin called WP-UserOnline http://wordpress.org/extend/plugins/wp-useronline/ to track down the visitors on your wordpress dashboard
It displays how many logged in visitors,normal visitors and how many bots are online at any given time! The advantage is it displays bots name and ip addresses of all visitors and its linked to whois.domaintools.com whois checker which is my favorite whois checker tool. So you can click on the ip to see the ip whois info!
And it provides nice control panel within your wordpress dashboard to configure things like Time Out (How long until it will remove the user from the database)
Download link is here- http://wordpress.org/extend/plugins/wp-useronline/
