Synopsis

                  ypbind [options]

NFS/NIS command. NIS binder process. ypbind is a daemon process typically activated at system startup time. Its function is to remember information that lets client processes on a single node communicate with some ypserv process. The information ypbind remembers is called a binding--the association of a domain name with the Internet address of the NIS server and the port on that host at which the ypserv process is listening for service requests. This information is cached in the file /var/yp/bindings/domainname.version.

Options

-c

Check configuration file for syntax errors, then exit.

-broadcast

Ignore configuration information in /etc/yp.conf and directly request configuration information from a remote system using ypset.

-broken-server

Allow connections to servers using normally illegal port numbers. Sometimes needed for compatibility with other versions of ypserv.

-f file

Read configuration information, from file instead of /etc/yp.conf.

-no-ping

Don’t ping remote servers to make sure they are alive.

--version

Print version information then exit.

-ypset

Allow remote machine to change the local server’s bindings. This option is very dangerous and should be used only for debugging the network from a remote machine.

-ypsetme

-debug
