Hi, can someone explain below "top" for me, I just cant imagin how thiese:
| Quote: | # rc-status
'Runlevel: default
dhcp [ started ]
ntpd [ started ]
sshd [ started ]
local [ started ]
mysql [ started ]
vixie-cron [ started ]
syslog-ng [ started ]
shorewall [ started ]
net.eth0 [ started ]
net.eth1 [ started ]
netmount [ started ]
uptimed [ started ]
apache2 [ started ]

applications can use this much memory:

| Unused memory is wasted memory. The Linux kernel will try to use all the available memory, one way or other. If the memory isn't used by the applications it will be used for disk caching. |
