The walldns-conf program

walldns-conf sets up a DNS wall service.

Interface

     walldns-conf acct logacct D ip

walldns-conf creates a service directory D that runs walldns. The name D must start with a slash and must not contain any special characters. Normally D is /etc/walldns.

You can run the service under svscan by creating a symbolic link in the svscan directory:

     ln -s D /service
The service will start within five seconds, and will be restarted upon reboot. You can use svc to control the service.

walldns-conf arranges for walldns to chroot to D/root and to run under the uid and gid of acct. The name acct must not contain any special characters.

walldns-conf arranges for walldns to listen for UDP packets on port 53 of ip, and to send outgoing packets from ip.

walldns-conf creates an automatically rotated log directory in D/log/main. The logs are owned by logacct. The corresponding multilog processes run under the uid and gid of logacct. The name logacct must not contain any special characters.
