NAME

ypbind - NIS binding process

SYNOPSIS

DESCRIPTION

ypbindfinds the server for a NIS domain and stores the information about itin abinding file.The binding file resides in the directory/var/yp/bindingand is conventionally nameddomainname.version.The only supported version is version 2.

Unless the option-debugis used, ypbind detaches itself from the controlling terminal and putsitself into background.ypbindusessyslog()for logging errors and warnings.

At startup or when receiving signal SIGHUP,ypbindparses the file/etc/yp.confand tries to use the entries for its initial binding. Valid entriesare

domainnisdomainserverhostname

: Use serverhostnamefor the domainnisdomain.

domainnisdomainbroadcast

: Use broadcast on the local net for domainnisdomain.

ypserverhostname

: Use serverserverfor the local domain. The IP-address ofservermust be listed in/etc/hosts.

If the file does not exist of if there are no valid entries,ypbindbroadcasts on the local net looking for a NIS server for the localdomain.

ypbindis split into two processes. The master process services RPC requestsasking for binding info. The slave process initializes the binding andchecks it periodically. Upon failure, the binding is invalidated andthe process tries again to find a valid server.

OPTIONS

-ypset: ypset(8)may be used to change the binding for a domain.
-ypsetme: ypset(8)may only be used from the local host to change thebinding for a domain.
-debug: startsypbindin debug mode.ypbindwill not put itself into background, and error messages and debugoutput are written to standard error.
-ipc: letsypbinduse IPC for the master-slave communication. It requires a kernel with IPCenabled. You must use this, if your root-Filesystem is on NFS.
-mmap: letsypbinduse mmap for the master-slave communication. This may fail with some olderkernels.
-broken_server: letsypbindaccept answers from servers running on an illegal port number. This shouldusually be avoided, but is required on Solaris 2.4 (there should be a patchfor Solaris which fixes this broken behaviour.)
-no-ping: preventsypbindfrom continually checking if the binding is alive. This option isintented for use with dialup connections to preventypbindfrom keeping the connection unnessecarily open or causing autodials.

FILES

/etc/yp.conf- configuration file.

/var/yp/binding/domainname.version- binding file containing information aboutdomain.

/var/run/ypbind.pid- contains the process id of the currently runningypbindmaster process.ypbindsets a write lock to this file to prevent multiple copies of itselffrom running.

BUGS

Binding to multiple domains is untested.ypbindwill only bind to one single server per domain.Load sharing between multiple servers for a single domain isnot supported.
