3.6.1 DKIPTAB
(IP-CommKit must be stopped before you update this table. See section 6.3 for details.)
The dkiptab is a new control file for IP-CommKit that tells the IP-CommKit software the IP
addresses assigned to the UTM and the host LAN interfaces. Even if you are upgrading a
computer from the CommKit Host Interface to IP-CommKit, you still must enter the dkiptab
before IP-CommKit will operate. While the installation scripts create a dkiptab file in the
appropriate directory, it contains only comments. Fortunately, the dkiptab is very easy to enter
with your favorite text editor. See the manual page (dkiptab(4)) for the file format and examples.
3.6.2 DKITRC AND DKITCFG
/etc/dkitrc is a shell script that starts and stops the IP-CommKit software on the host computer.
The installation scripts configure inittab(4) so that /etc/dkitrc is run automatically when the run
level of the host computer changes, i.e., at startup and shutdown. Specifically, the IP-CommKit
software starts when the host enters run level 2, and stops when the host enters either run level 0
or 1:
The operation of dkitrc is controlled by /etc/opt/dk/dkitcfg. The dkitrc and dkitcfg scripts for
IP-CommKit are different from the scripts used in some versions of CommKit Host Interface
software. If you are upgrading a computer from the CommKit Host Interface to IP-CommKit, and
you customized the configuration in dkitrc script, you will need to customize the dkitcfg script
supplied with the IP-CommKit software. The most common reason for customizing the dkitcfg
script is to change the number of channels available per interface from the default value of 64.
The dkitcfg script itself contains instructions for making modifications. It should not be necessary
to make any modifications to the dkitrc script.
3.6.3 DKSRVTAB
If you are upgrading your computer from the CommKit Host Interface to IP-CommKit, it’s likely
that the tables used by dkserver [see srvtab(4)] have already been customized. No changes to
these tables are needed to use IP-CommKit.
