NAME

       fedfs-delete-junction - send a FEDFS_DELETE_JUNCTION ADMIN protocol request

SYNOPSIS

       fedfs-delete-junction [-?d] [-n nettype] [-h hostname] [-s security] path

INTRODUCTION

       RFC  5716  introduces the Federated File System (FedFS, for short).  FedFS is an extensible standardized mechanism by which system adminis-
       trators construct a coherent namespace across multiple file servers using file system referrals.  For further details, see fedfs(7).

       FedFS-enabled file servers allow remote administrative access via an authenticated RPC protocol known as the FedFS ADMIN  protocol.   Using
       this protocol, FedFS administrators manage FedFS junctions and NSDB connection parameter information on remote FedFS-enabled file servers.

DESCRIPTION

       The  fedfs-delete-junction(8) command is part of a collection of low-level single-use programs that is intended for testing the FedFS ADMIN
       protocol or for use in scripts.	It sends a single FEDFS_DELETE_JUNCTION request to a remote FedFS ADMIN protocol service.

       The FEDFS_DELETE_JUNCTION request deletes a FedFS junction in a local file system on a remote file  server.   The  fedfs-delete-junction(8)
       command	takes  a  single  positional parameter which is the pathname on the remote server of the junction to be deleted.  This pathname is
       relative to the root of the local file system on the remote server.

       The FEDFS_DELETE_JUNCTION request does not remove the FSN record associated with the deleted junction.  Other  junctions  may  continue	to
       refer to the FSN in the deleted junction.

       When  no  junction refers to this FSN, use the nsdb-delete-fsn(8) command to delete the FSN and children FSL records.  Resolving a junction
       that contains an FSN UUID without a matching FSN record on the NSDB results in an error on the file server.

OPTIONS

       -d, --debug
	      Enables debugging messages during operation.

       -?, --help
	      Displays fedfs-delete-junction(8) version information and a usage message on stderr.

       -h, --hostname=hostname
	      Specifies the hostname of a remote FedFS ADMIN service.  If this option is not specified, the default value is localhost.

       -n, --nettype=nettype
	      Specifies the transport to use when contacting the remote FedFS ADMIN service.  Typically the nettype is one of tcp or udp.  If this
	      option is not specified, the default value is netpath.  See rpc(3t) for details.

       -s, --security=flavor
	      Specifies  the security flavor to use when contacting the remote FedFS ADMIN service.  Valid flavors are sys, unix, krb5, krb5i, and
	      krb5p.  If this option is not specified, the unix flavor is used.  See the SECURITY section of this man page for details.

EXAMPLES

       Suppose you are the FedFS administrator of the example.net FedFS domain.  To delete the existing FedFS junction	/export/junction1  on  the
       file server fs.example.net, use:

	      $ fedfs-delete-junction -h fs.example.net /export/junction1

SECURITY

       By  default,  or  if  the  sys  and unix flavors are specified with the --security=flavor option, the fedfs-create-junction(8) command uses
       AUTH_SYS security for the Remote Procedure Call.  AUTH_SYS has known weaknesses and should be avoided on untrusted networks.

       The RPC client uses the Kerberos v5 GSS mechanism if a Kerberos security flavor is specified.  When specifying a Kerberos security  flavor,
       the user must first obtain a valid Kerberos ticket using kinit(1) before running fedfs-create-junction(8).

       The AUTH_NONE security flavor is no longer supported by this implementation.
