Troubleshooting NIS



The following utilities are available for troubleshooting NIS. See their reference manual pages for complete information. 

 -----------------------------------------------------------------
 Utility         Function
 -----------------------------------------------------------------
 ypcat(NC)       displays the contents of an NIS map.
 ypmatch(NC)     prints the value for one or more specified keys
                 in an NIS map.
 yppoll(NADM)    asks any NIS server for information about a map
                 that it holds internally
 ypwhich(NADM)   tells you which NIS server an NIS client is
                 currently using for NIS, or which NIS server is
                 master of a named map
 rpcinfo(NADM)   displays RPC information from a specified RPC
                 server.  Use rpcinfo to check whether portmapper,
                 ypbind, and (for NIS servers) ypserv are running.
                 If exporting filesystems, the mountd service
                 should be registered.
 ping(ADMN)      reports roundtrip time and packet loss
                 statistics.  Use ping to ensure a network
                 connection can be made between hosts.
The Account Manager is used to administer distributed and local NIS accounts.
