rpc.gssd - rpcsec_gss daemon
SYNOPSIS
rpc.gssd [-f] [-k keytab] [-p pipefsdir] [-v] [-r] [-d ccachedir]
DESCRIPTION
The rpcsec_gss protocol gives a means of using the gss-api generic
security api to provide security for protocols using rpc (in particuā
lar, nfs). Before exchanging any rpc requests using rpcsec_gss, the
rpc client must first establish a security context. The linux kernel's
implementation of rpcsec_gss depends on the userspace daemon rpc.gssd
to establish security contexts. The rpc.gssd daemon uses files in the
rpc_pipefs filesystem to communicate with the kernel.
OPTIONS-f Runs rpc.gssd in the foreground and sends output to stderr (as
opposed to syslogd)
-k keytab
Tells rpc.gssd to use the keys for principals nfs/hostname in
keytab to obtain machine credentials. The default value is
"/etc/krb5.keytab".
-p path
Tells rpc.gssd where to look for the rpc_pipefs filesystem. The
default value is "/var/lib/nfs/rpc_pipefs".
-d directory
Tells rpc.gssd where to look for kerberos credential files. The
default value is "/tmp".
-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).
-t timeout
Timeout, in seconds, for kernel gss contexts. This option allows
you to force new kernel contexts to be negotiated after timeout
seconds, which allows changing Kerberos tickets and identities
frequently. The default is no explicit timeout, which means the
kernel context will live the lifetime of the Kerberos service
ticket used in its creation.
