svnserve - Server for the 'svn' repository access method
svnserve allows access to Subversion repositories using the svn network
protocol. It can both run as a standalone server process, or it can
run out of inetd. You must choose a mode of operation when you start
svnserve. The following options are recognized:
Causes svnserve to run in daemon mode. svnserve backgrounds
itself and accepts and serves TCP/IP connections on the svn port
(3690, by default).
Causes svnserve to listen on port when run in daemon mode.
Causes svnserve to listen on the interface specified by host,
which may be either a hostname or an IP address.
When used together with -d, this option causes svnserve to stay in
the foreground. This option is mainly useful for debugging.
Causes svnserve to use the stdin/stdout file descriptors, as is
appropriate for a daemon running out of inetd.
Displays a usage summary and exits.
Print svnserve's version and the repository filesystem back-end(s)
a particular svnserve supports.
-r root, --root=root
Sets the virtual root for repositories served by svnserve. The
pathname in URLs provided by the client will be interpreted rela-
tive to this root, and will not be allowed to escape this root.
Force all write operations through this svnserve instance to be
forbidden, overriding all other access policy configuration. Do
not use this option to set general repository access policy - that
is what the conf/svnserve.conf repository configuration file is
for. This option should be used only to restrict access via a
certain method of invoking svnserve - for example, to allow write
access via SSH, but not via a svnserve daemon, or to create a
restricted SSH key which is only capable of read access.
Causes svnserve to run in tunnel mode, which is just like the
inetd mode of operation (serve one connection over stdin/stdout)
except that the connection is considered to be pre-authenticated
with the username of the current uid. This flag is selected by
the client when running over a tunnel agent.
When combined with --tunnel, overrides the pre-authenticated user-
name with the supplied username. This is useful in combination
with the ssh authorized_key file's "command" directive to allow a
single system account to be used by multiple committers, each hav-
ing a distinct ssh identity.
When running in daemon mode, causes svnserve to spawn a thread
instead of a process for each connection. The svnserve process
still backgrounds itself at startup time.
When specified, svnserve reads filename once at program startup
and caches the svnserve configuration. The password and autho-
rization configurations referenced from filename will be loaded on
each connection. svnserve will not read any per-repository
conf/svnserve.conf files when this option is used. See the
svnserve.conf(5) man page for details of the file format for this
When specified, svnserve will write its process ID to filename.
Causes svnserve to accept one connection on the svn port, serve
it, and exit. This option is mainly useful for debugging.
Unless the --config-file option was specified on the command line, once
the client has selected a repository by transmitting its URL, svnserve
reads a file named conf/svnserve.conf in the repository directory to
determine repository-specific settings such as what authentication
database to use and what authorization policies to apply. See the
svnserve.conf(5) man page for details of that file format.
