1) You need to un-gzip then un-tar the file.gzip -d somefile.tar.gzthen...tar xvf somefile.tar |
These two steps can be done in one step by using gnu tar, which is the standard tar command on LINUX systems. Try the following:
tar zxvf somfile.tar.gz
This saves a step, plus saves on diskspace by not creating the uncompressed tarball.
2) Learn VI (non-GUI text editor). If your system won’t boot into X (the GUI) how would you find and fix the problem? |
This is one of the most important tips that anyone can give you. VI isn''t user friendly, I like to call it expert friendly, but VI is your friend. Learn it well.
It is on EVERY UNIX/LINUX system that there is. It is one of the most powerful text editors that exists.
Note: a text editor is not a Word Processor.
If you want to learn some power-user stuff, learn awk & sed. You can use these tools in combination with other things to do about anything in UNIX. They are also very powerful.
Another tip, don''t log in as "root". Create a normal user account and log in as that user. Only use root when it is needed. You can easily become root by using "su -", but only stay logged in as root for as long as needed, then exit back to your normal account.
As soon as you can figure out how, disable all non secure telnet like programs and replace them with the equivalent secured versions like ssh. This way you don''t transmit passwords in clear text. The SecureShell commands encrypt everything, so no one will be able to see your passwords and other stuff in clear text.
Like I said about VI, LINUX isn''t user friendly, it''s expert friendly. You need to learn a lot about it to feel comfortable with it, and you need to learn a lot to be able to make it secure. But, once you have taken the time to learn it, it is very stable and very secure. My LINUX box has been up and running for over a year. How long has it been since you have had to reboot your PC? I normally end up rebooting my PC at least once or twice a week.
