RPC.LOCKD(8) BSD System Manager's Manual RPC.LOCKD(8) NAME rpc.lockd -- NFS file locking daemon SYNOPSIS rpc.lockd [-d debug_level] [-g grace period] [-p port] DESCRIPTION The rpc.lockd utility provides monitored and unmonitored file and record locking services in an NFS environment. To monitor the status of hosts requesting locks, the locking daemon typically operates in conjunction with rpc.statd(8). Options and operands available for rpc.lockd: -d The -d option causes debugging information to be written to sys- log, recording all RPC transactions to the daemon. These mes- sages are logged with level LOG_DEBUG and facility LOG_DAEMON. Specifying a debug_level of 1 results in the generation of one log line per protocol operation. Higher debug levels can be specified, causing display of operation arguments and internal operations of the daemon. -g The -g option allow to specify the grace period, in seconds. During the grace period rpc.lockd only accepts requests from hosts which are reinitialising locks which existed before the server restart. Default is 30 seconds. -p The -p option allow to force the daemon to bind to the specified port, for both AF_INET and AF_INET6 address families. Error conditions are logged to syslog, irrespective of the debug level, using log level LOG_ERR and facility LOG_DAEMON. The rpc.lockd utility must NOT be invoked by inetd(8) because the proto- col assumes that the daemon will run from system start time. Instead, it should be configured in rc.conf(5) to run at system startup. FILES /usr/include/rpcsvc/nlm_prot.x RPC protocol specification for the net- work lock manager protocol. SEE ALSO syslog(3), rc.conf(5), rpc.statd(8) STANDARDS The implementation is based on the specification in "Protocols for X/Open PC Interworking: XNFS, Issue 4", X/Open CAE Specification C218, ISBN 1 872630 66 9. HISTORY A version of rpc.lockd appeared in SunOS 4. BUGS The current implementation serialises locks requests that could be shared. BSD April 3, 2007 BSD
