Installation guide

the gated routing daemon. If the DIGITAL supplied gated is detected,
then the /etc/gated.conf file is moved to /etc/ogated.conf.
Otherwise, if a user-supplied or customized gated is detected, then both
the /etc/gated.conf and the /usr/sbin/gated files are saved with the
.PreUPD suffix.
When the system is installed, the new gated R3.5 is the default version in
/usr/sbin/gated. The old gated Version 1.9 is supplied in
/usr/sbin/ogated. Also, corresponding, older gated reference pages are
saved with an o prefix.
G.9.1.1 ULTRIX Migration Issues
There are no ULTRIX migration issues.
G.9.2 Dynamic Host Configuration Protocol
This release contains both a client and a server Dynamic Host
Configuration Protocol (DHCP) daemon. For DHCP client configuration,
use the netconfig utility. For configuration of client parameters on the
DHCP server, use the /usr/bin/X11/xjoin utility, which provides a
graphical user interface to the /etc/bootptab file.
For more information on DHCP, see joinc
(8) and joind(8).
G.9.2.1 ULTRIX Migration Issues
There are no ULTRIX migration issues.
G.9.3 Point-to-Point Protocol
This release supports Point-to-Point Protocol (PPP), including support for
BSD-style compression of entire packets. This is a negotiated option. If a
foreign peer cannot handle this, it should be gracefully rejected via the
Protocol-Reject of the Link Control Protocol (LCP).
When using PPP with modems doing compression, it may be desirable to
force no BSD-style compression. To do this, put -bsdcomp in either
/etc/ppp/options, or on the pppd command line.
PPP now has a configurable (at boot time) number of interfaces. The
default is 1. To specify a higher value, add the following line to the
/etc/sysconfigtab file and reboot the system:
ppp:nppp=x
PPP documentation is available in pppd(8), pppstats(8), and chat(8), and
in the Network Administration manual.
