Configure System Services

Installing Gentoo - Configure System Services

Now that we've installed all of our system utilities, we need to schedule them to start with the system.

Optional - Change your ssh port

The default port for ssh connections is 22. Much like with FTP servers configured to use the default port (21), people program bots to find an ssh server listening on the default port and then hammer it, using a password dictionary, to try to guess the root password. Changing the port to something other than the default is a very easy way to deter 99% of such attacks.

The ssh port setting is stored in the file /etc/ssh/sshd_config. Find the line containing the directive Port, uncomment it, and replace yourport in the example below with your desired port.

# nano -w /etc/ssh/sshd_config

file: /etc/sshd/sshd_config

... 
Port yourport
...

Start networking with the system.

# rc-update add net.eth0 default

Enable numlock at startup.

# rc-update add numlock default

Start the ssh daemon, so you can connect remotely to your computer.

# rc-update add sshd default

Start the system logger, so you can view system logs for security and troubleshooting purposes.

#  rc-update add syslog-ng default

Start the cron deamon, so scheduled tasks are run when invoked.

# rc-update add vixie-cron default

Start the ntp daemon, ensuring your system time remains in sync.

# rc-update add ntpd default

Your system services are now scheduled to start when the system boots. The next step is to Configure the Kernel.
