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 ### -v ### -r output (can be specified multiple times). ### -i output (can be specified multiple times). ### -p ### -n 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**. ## SEE ALSO ### [rpc.gssd(8)](https://www.chedong.com/phpMan.php/man/rpc.gssd/8/markdown), ## AUTHORS Dug Song <> Andy Adamson <> Marius Aamodt Eriksen <> J.
