Tip of the week
StartX by default listens on port 6000, to see this you can type at a terminal:
netstat -an
This is not considered secure, or good linux practice to leave it listening for connections, since this can be exploited and leave you vulnerable. To close the connection, and make X a more secure place change to the directory where startx is at:
cd /usr/X11R6/bin/
With your editor open startx, and look for the following line:
serverargs=" "
Change the line now to reflect this:
serverargs="-nolisten tcp"
Be sure you don't forget to add the dash ---> - in front of 'nolisten tcp' Now save and close startx, log off Xwindows your desktop, and log back in, then run 'netstat -an' and you will now see that 6000 has been closed and is not there anymore
Comments
take it to the wiki
blogs will be out of sight soon.
follow the books link in the top navigation bar then wiki and edit to add a wiki word, then simply click on the wiki word to create a new page.
if you like we can think of a way to make weekly columns, where you can write weekly tips and they get published in a more organized manner, kinda like a special tips blog.
cheers, Alaa
