Sto diko mou mhxanhma mporeis na deis kati san:

	% sockstat -l4
	USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS      
	tty      comsat    5704    2 udp4   *:512                 *:*                  
	httpd    httpd      361   16 tcp4   *:80                  *:*                  
	root     sendmail   276    4 tcp4   *:25                  *:*                  
	root     sshd       273    3 tcp4   *:22                  *:*                  
	root     inetd      268    5 tcp4   *:113                 *:*                  
	root     ntpd       249    4 udp4   *:123                 *:*                  
	bind     named      247   20 udp4   127.0.0.1:53          *:*                  

Me mono comsat,apache,sendmail,sshd,identd,ntpd,named oi apaithseis sto
/var/log einai mikres (ta logs ginontai rotate otan jeperasoun ta 10 Mb se
megethos, kai den krataw pano apo 10 rotations).  Gia to /var/spool/mqueue
exo krathsei arketo xoro opws tha deis apo to:

	% df
	Filesystem  1K-blocks     Used    Avail Capacity  Mounted on
	/dev/ad0s1a    194548    64752   114233    36%    /

	/dev/ad0s3f   4065262  1535920  2204122    41%    /usr
	/dev/ad0s3g  34804895  4179595 27840909    13%    /home
	devfs               1        1        0   100%    /dev
	procfs              4        4        0   100%    /proc

O perissoteros xoros pantos exei paei sto /home me diafora.
