rpc.svcgssd(8)                         System Manager's Manual                        rpc.svcgssd(8)

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 in‐
       clude:

       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.
