[ale] apache recovery

[Jim Popovitch]

Hi Robert,

As far as httpd errors, none of those are problems.  I see those in my log
files all the time.  Your issue seems to be just that your root partition
filled up.  You need to delete some data so that /tmp has space (boot into
single user mode).  I would also suggest putting /var and /tmp on separate
partitions.

As for your ftp server... I would advise disabling it.  In my opinion there
isn't a good ftp server.

It is impossible to say that your box wasn't hacked, the best thing to do
would be go buy a new harddrive at MicroCenter (~$100) and install Mandrake
8.2 on it.  Then mount the old disk and copy user files over.
