- Once you have the DNS tables set up and are running in.named from
- /etc/rc.local, and have NIS running, you have three additional changes to
- make from the default Sun setup.
-
- 1) In /var/yp/Makefile, remove the comment
- from the line that reads:
- #B=-b
- and add one to the line that read:
- B=
- This tells the makedbm program to make the NIS databases in such a way to
- cooperate with DNS.
-
- 2) In /etc/rc.local, set the -d switch for ypserv, again to get the NIS
- stuff to interact with DNS.
-
- 3) Create an /etc/resolv.conf on the NIS/DNS server with the following info:
- domain your.domain
- nameserver ip-number_of_your_primary_nameserver
- nameserver ip-number_of_your_secondary_nameserver
-
- When you run /var/yp/Makefile, watch to make sure the hosts databases are
- remade. If they are not, then touch /etc/hosts and remake.
-
- You also will have to reboot (fastboot) I believe to get the ypserv switch
- to take effect, although I guess you could kill the pid of ypserv and
- restart it with the -d.
-
- Use /usr/etc/nslookup to check name resolution of your local and some remote
- hosts.
-
- I hope this helps. This is what I am doing at GMI, but we are a nearly
- homogeneous network, with a Sun server doing both DNS and NIS, and about 25
- workstations being served. We have one HP and a couple of DEC workstations,
- but I am not sure they are getting completely satisfactory DNS. The PC's,
- running Netware, with CUTCP for TCP/IP, are getting IP addresses with bootp
- from the Sun server.
