comment Transfer a 30GB tar file from one remote server to another - restrained by disk space
If security is not a problem (I mean you trust the network between the two machines) nc is also an option. On the server: tar -zc source | nc -l 1313 On the client: nc SERVER_IP 1313 | tar -zx

comment Check if port is open or closed on a Linux server using SSH?
nc is (better) alternative to telnet. It supports UDP too.

comment Security of symlink to directory outside webroot set to 777?
My point was to create another group (for example webusers) and add each webuser to it. Then you can assign write permission to it and the rest of apache group members won't be able to write there.

comment Change the port number of outgoing packets originating from local process
The main point was to change the destination port only. If I don't touch the source port, the connection will work fine. You are right that there is no such tool, so after measuring the alternatives I agree that custom netfilter module is the way to go.

comment Change the port number of outgoing packets originating from local process
Yes, I agree with Eugene. I considered both diverted sockets and netfilter module. However non-programming solution is preferred. My colleagues suggest a workaround to redirect to localhost and then masquerade. I'll keep you posted on the final solution. Thanks for the comments!

comment How to speed up the Kubuntu installed on virtualbox running on Windows 7?
As far as I know - Windows XP 32bit can't address more than 4G RAM. If you do all your development on Linux why don't you install Kubuntu for your main OS and run Windows XP in virtual machine?

Well, you should also make sure that Windows has enough RAM to operate well. For start, what are you doing on the virtual machine? You can use top to examine CPU and memory usage. Linux caches memory so if your used percentage is high it may be normal. However if you have swap usage - probably you need more RAM.
