On some occasions, the system administrator will be faced with the
|
||||
problem of recovering from a complete disaster, such as
|
||||
forgetting the root password or trashing filesystems. The best advice
|
||||
is, <em>don't panic.</em> Everyone makes stupid mistakes---that's the
|
||||
best way to learn about system administration: the hard way.
|
||||
<P>
|
||||
Linux is not an unstable version of UNIX. In fact, I have had
|
||||
fewer problems with system hangs than with commercial
|
||||
versions of UNIX on many platforms. Linux also benefits from a
|
||||
strong complement of wizards who can help you get out of a bind.
|
||||
<P>
|
||||
The first step in investigating any problem is
|
||||
to attempt to fix it yourself. Poke around, see how things work.
|
||||
Too much of the time, a system administrator will post a desperate
|
||||
plea for help before looking into the problem at all. Most of the
|
||||
time, you'll find that fixing problems yourself is actually very
|
||||
easy. It is the path to guruhood.
|
||||
<P>
|
||||
There are very few cases where reinstalling the system from
|
||||
scratch is necessary. Many new users accidentally delete some
|
||||
essential system file, and immediately reach for the installation
|
||||
disks. This is not a good idea. Before taking such drastic measures,
|
||||
investigate the problem and ask others to help fix things up. In
|
||||
almost all cases, you can recover your system from a maintenance
|
||||
diskette.
