- Or get resolv+-2.1 from your nearest ftp-site. It replaces the resolver-
- routines in the SunOS shared library. It supports a /etc/host.conf file,
- much like the Ultrix /etc/svc.conf file.
-
- We are running with a DNS- and NIS-master on an Ultrix-server,
- DNS-secondary and NIS-slave on the Sun-server and DNS-client and
- NIS-client on all Sun/Ultrix workstations.
-
- You can disable DNS-usage by setting an environment variable before
- starting a program. We had to do that for mountd and sendmail.
-
- >(Sun should be sued for damages caused by this YP/DNS fuckup).
-
- Yeah.
