Hey guys, today when I logged in my linode machine it felt a bit slow so I ran ps aux and found some stuff running which I don't recall installing and I wanted to know if they come with the default ubuntu linode installation or maybe someone has hacked my linode.

Below is the ps aux response.

Some of the stuff I don't recognize:

/sbin/getty -8 38400 hvc0
/usr/sbin/ntpd -p /var/run/ntpd.pid -g -u 102:104
udevd --daemon
rsyslogd -c4
dhclient3 -e IF_METRIC=100 -pf /var/run/dhclient.eth0.pid -lf
upstart-udev-bridge --daemon


Thanks

ntpd basically syncs the time of your server with other time servers.
rsyslogd handles the syslog.
dhclient handles DHCP.
udevd passes kernel events to udev in the correct order.

Basically you are fine.

the getty for hvc0 is the lish console
