intro

There are pages which document the running of the system, such as afterboot(8), ifconfig(8), security(8), and the configuration files located in /etc. Procedures concerning system failure are documented in crash(8).
Section 8 pages also describe network services and daemons. The rest of this page discusses some of the main daemons available on the OpenBSD system, and how to enable/disable them.
System daemons are controlled by the script rc(8), which is in turn configured by rc.conf(8). For example the HTTP daemon httpd(8) is controlled by the following line from rc.conf(8):
httpd_flags=NO
Thus it is not started by default. To enable or disable daemon processes, administrators should edit the file rc.conf.local(8) or use the rcctl(8) utility. The rc.conf.local(8) file overrides variable assignments in rc.conf(8). So to enable httpd(8), the following line might be added to /etc/rc.conf.local:
httpd_flags="-v"
As can be seen above, this method is also used to specify additional options.
Below is a list of some of the daemons available. For further information, see rc(8) and the individual pages for the utilities.
Relevant rc.conf(8) variables: amd_flags and amd_master.
domain nts.umn.edu nameserver 128.101.101.101 nameserver 134.84.84.84 search nts.umn.edu. umn.edu. lookup file bind
If using a caching name server, add the line "nameserver 127.0.0.1" first.
Relevant rc.conf(8) variables: nsd_flags and unbound_flags.
Relevant rc.conf(8) variables: ntpd_flags.
Relevant rc.conf(8) variables: bootparamd_flags, dhcpd_flags, and dhcrelay_flags.
Relevant rc.conf(8) variables: rbootd_flags.
Relevant rc.conf(8) variables: httpd_flags.
Relevant rc.conf(8) variables: mountd_flags and nfsd_flags.
Relevant rc.conf(8) variables: relayd_flags.
Relevant rc.conf(8) variables: bgpd_flags, eigrpd_flags, ospfd_flags, and ripd_flags.
Relevant rc.conf(8) variables: portmap_flags.
Relevant rc.conf(8) variables: ypbind_flags.
After starting YP client services, perform the remaining YP activation as described in passwd(5) and group(5).
In particular, to enable YP passwd support, you'll need to add the following line to /etc/master.passwd:
+:*::::::::
You do this by using vipw(8).
There are many more YP man pages available to help you. You can find more information by starting with yp(8).
