# [NAME](#NAME)

rpc.svcgssd - server-side rpcsec\_gss daemon

# [SYNOPSIS](#SYNOPSIS)

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

# [DESCRIPTION](#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](#OPTIONS)

[**-f**](#f)

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

[**-v**](#v)

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

[**-r**](#r)

If the rpcsec\_gss library supports setting debug level, increases the verbosity of the output (can be specified multiple times).

[**-i**](#i)

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

[**-p**](#p)

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

[**-n**](#n)

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

# [CONFIGURATION FILE](#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**](#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**](#verbosity)

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

[**rpc-verbosity**](#rpc-verbosity)

Value which is equivalent to the number of **-r**.

[**idmap-verbosity**](#idmap-verbosity)

Value which is equivalent to the number of **-i**.
