Computer Topics
From Ezee.co.uk
Computer Topics, including Servers, Linux and security
I will be putting in notes here of items such as security fixes, how to use certain useful linux commands, small scriptlets I have written or use and anything else I find in day to day work.
Please note this is a work in progress. Currently I am adding topic headers as I think of them and then coming back to fill in details as I find time. Most of it regards Linux System administration and some development work. All of it is practical based stuff I do in the real world. I intend to make this into a bit of a Linux SysAdmin Wiki as I get time, I may open it up for editing by other later.
If you want to contact me please email -> 
please note I don't monitor this frequently but will respond as soon as I do.
I won't be adding beginner stuff here or items not relating to managing live servers.
