rpc.statd !!!rpc.statd NAME SYNOPSIS DESCRIPTION OPTIONS TCP_WRAPPERS SUPPORT FILES SEE ALSO AUTHORS ---- !!NAME rpc.statd - NSM status monitor !!SYNOPSIS __/sbin/rpc.statd [[-F] [[-d] [[-?] [[-n name ] [[-o port ] [[-p port ] [[-V]__ !!DESCRIPTION The __rpc.statd__ server implements the NSM (Network Status Monitor) RPC protocol. This service is somewhat misnomed, since it doesn't actually provide active monitoring as one might suspect; instead, NSM implements a reboot notification service. It is used by the NFS file locking service, __rpc.lockd__, to implement lock recovery when the NFS server machine crashes and reboots. __Operation__ For each NFS client or server machine to be monitored, __rpc.statd__ creates a file in __/var/lib/nfs/sm__. When starting, it iterates through these files and notifies the peer __rpc.statd__ on those machines. !!OPTIONS __-F__ By default, __rpc.statd__ forks and puts itself in the background when started. The __-F__ argument tells it to remain in the foreground. This option is mainly for debugging purposes. __-d__ By default, __rpc.statd__ sends logging messages via syslog(3) to system log. The __-d__ argument forces it to log verbose output to __stderr__ instead. This option is mainly for debugging purposes, and may only be used in conjunction with the __-F__ parameter. __-n, --name__ ''name'' specify a name for __rpc.statd__ to use as the local hostname. By default, __rpc.statd__ will call gethostname(2) to get the local hostname. Specifying a local hostname may be useful for machines with more than one interfaces. __-o, --outgoing-port__ ''port'' specify a port for __rpc.statd__ to send outgoing status requests from. By default, __rpc.statd__ will ask portmap(8) to assign it a port number. As of this writing, there is not a standard port number that __portmap__ always or usually assigns. Specifying a port may be useful when implementing a firewall. __-p, --port__ ''port'' specify a port for __rpc.statd__ to listen on. By default, __rpc.statd__ will ask portmap(8) to assign it a port number. As of this writing, there is not a standard port number that __portmap__ always or usually assigns. Specifying a port may be useful when implementing a firewall. __-?__ Causes __rpc.statd__ to print out command-line help and exit. __-V__ Causes __rpc.statd__ to print out version information and exit. !!TCP_WRAPPERS SUPPORT This __rpc.statd__ version is protected by the __tcp_wrapper__ library. You have to give the clients access to __rpc.statd__ if they should be allowed to use it. To allow connects from clients of the .bar.com domain you could use the following line in /etc/hosts.allow: statd: .bar.com You have to use the daemon name __statd__ for the daemon name (even if the binary has a different name). For further information please have a look at the tcpd(8) and hosts_access(5) manual pages. !!FILES __/var/lib/nfs/state /var/lib/nfs/sm/* /var/lib/nfs/sm.bak/*__ !!SEE ALSO __rpc.nfsd(8), portmap(8)__ !!AUTHORS Jeff Uphoff Olaf Kirch H.J.
