Administering Remote Procedure Calls (RPC)

Setting the Secure RPC domain name

All machines supporting Secure RPC must have what is known as a secure RPC domain name. By default, a machine's Secure RPC domain name is null and, because it is null, Secure RPC will not work on the machine.

A domain name can be set using the domainname(1Mnis) command. If NIS is used, it remembers the domain name across reboots. If NIS is not used, administrators need to either:

Edit the file /etc/conf/pack.d/name/space.c, and set the SRPC_DOMAIN tunable to the desired Secure RPC domain name.
Call domainname in the RPC start-up script /etc/rc2.d/S75rpc.

For example, to change a machine's domain name from null to finance using the first method:

Find the following line in /etc/conf/pack.d/name/space.c:
```
#define SRPC_DOMAIN=""
```
Change this to:
```
#define SRPC_DOMAIN="finance"
```
Rebuild the kernel and reboot your system:

/etc/conf/bin/idbuild -B
cd /
shutdown -y -g0 -i6
