Think Yourself a System Administrator?
Do you think yourself a system administrator? Yes? Ok; try giving answers of following
- How many files are installed on a freshly installed Windows 2003 or Fedora 4 (or an OS of your choice)?
- What’s the ACL of C:\Windows or /bin (or other similar location in other OS)?
- How many files are updated/deleted/added when SP1 (or some other popular patch) is installed?
- How many services (or daemon) are running on a freshly installed Windows / Fedora 4? Name them and what do they do?
- How many TCP and UDP ports are opened on a freshly installed Windows / Fedora 4? Which processes are bound to them and what are their implications?
Thinking that what kind of ridiculous questions these are? Yes? Ok; try asking any medial doctor these questions
- How many bones exist in a human body? What each and every one of it does?
- How many organs exist in human body?
- How many glands exist in some particular place?
- How many arteries / veins exist in some particular place?
I hope they will answer quite satisfactory…I guess this is the reason why medical field is more organized and less prone to mishaps!
Today I calculated how many files exists on a freshly installed Windows 2003 and what are their default NTFS ACLs settings are. And I am kinda surprised that its pretty useful information and every sys-admin should know this. In case you are curious; there are about 600+ ACL entries in different files/folders on a freshly installed Windows 2003.
Anyways; happy system administration…
Sometimes I love it...but rest of the time I hate it <smile />
