NAME

       rpc.svcgssd - server-side rpcsec_gss daemon

SYNOPSIS

       rpc.svcgssd [-n] [-v] [-r] [-i] [-f] [-p principal]

DESCRIPTION

       The rpcsec_gss protocol gives a means of using the gss-api generic security api to provide
       security for protocols using rpc (in particular, nfs).  Before exchanging any rpc requests
       using  rpcsec_gss,  the  rpc  client  must first establish a security context with the rpc
       server.  The linux kernel's implementation of rpcsec_gss depends on the  userspace  daemon
       rpc.svcgssd  to  handle context establishment on the rpc server.  The daemon uses files in
       the proc filesystem to communicate with the kernel.

OPTIONS

       -f     Runs rpc.svcgssd in the foreground and  sends  output  to  stderr  (as  opposed  to
              syslogd)

       -v     Increases the verbosity of the output (can be specified multiple times).

       -r     If  the rpcsec_gss library supports setting debug level, increases the verbosity of
              the output (can be specified multiple times).

       -i     If the nfsidmap library supports setting debug level, increases  the  verbosity  of
              the output (can be specified multiple times).

       -p     Use principal instead of the default nfs/FQDN@REALM.

       -n     Use  the  system  default  credentials  (host/FQDN@REALM)  rather  than the default
              nfs/FQDN@REALM.

CONFIGURATION FILE

       Some of the options that can be set on the command line can  also  be  controlled  through
       values  set  in  the  [svcgssd]  section  of the /etc/nfs.conf configuration file.  Values
       recognized include:

       principal
              If set to system this is equivalent to the -n option.  If set to any  other  value,
              that is used like the -p option.

       verbosity
              Value which is equivalent to the number of -v.

       rpc-verbosity
              Value which is equivalent to the number of -r.

       idmap-verbosity
              Value which is equivalent to the number of -i.
