Practical UNIX and Internet Security, 2ed
by Simson Garfinkel and Gene Spafford


Here are the changes that were made for the 3/99 reprint:


{298} Example on how to backup log files:

 # make a copy of the log file and zero the old one
 rm /var/adm/wtmp.old
 ln /var/adm/wtmp.old /var/adm/wtmp
 cp /dev/null /var/adm/wtmp
 mv /var/adm/wtmp.nul /var/adm/wtmp

It now reads:

 mv /var/adm/wtmp /var/adm/wtmp.old
 cp /dev/null /var/adm/wtmp
 chmod 600 /var/adm/wtmp


(954) "netnews~firewalls, 661"

has been changed to read:

      "netnews (see Usenet)"


(956) The entries "one" and "Open Source Distribution" have been
deleted.


(968) A subentry "firewealls, 661" has been added under the entry
Usenet.
