rpc.svcgssd - server-side rpcsec_gss daemon
rpc.svcgssd [-n] [-v] [-r] [-i] [-f] [-p principal]
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.
-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.
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.
