SVN::Notify::Mirror::SUser)Contributed Perl DocumenSVN::Notify::Mirror::SSH(3)

NAME
       SVN::Notify::Mirror::SSH	- Mirror a repository path via SSH

SYNOPSIS
       Use svnnotify in	post-commit:

	 svnnotify --repos-path	"$1" --revision	"$2" \
	  --handler Mirror::SSH	--to "/path/to/www/htdocs" \
	  [--svn-binary	/full/path/to/svn] \
	  [[--ssh-host remote_host] [--ssh-user	remote_user] \
	  [--ssh-tunnel	10.0.0.2] \
	  [--ssh-identity /home/user/.ssh/id_rsa]]

       or better yet, use SVN::Notify::Config for a more sophisticated setup:

	 #!/usr/bin/perl -MSVN::Notify::Config=$0
	 --- #YAML:1.0
	 '':
	   PATH: "/usr/bin:/usr/local/bin"
	 'path/in/repository':
	   handler: Mirror
	   to: "/path/to/www/htdocs"
	 'some/other/path/in/repository':
	   handler: Mirror::SSH
	   to: "/path/to/remote/www/htdocs"
	   ssh-host: "remote_host"
	   ssh-user: "remote_user"
	   ssh-tunnel: "10.0.0.2"
	   ssh-identity: "/home/user/.ssh/id_rsa"

DESCRIPTION
       Keep a directory	in sync	with a portion of a Subversion repository.
       Typically used to keep a	development web	server in sync with the
       changes made to the repository.	This directory can either be on	the
       same box	as the repository itself, or it	can be remote (via SSH
       connection).

USAGE
       Depending on whether the	target is a "Local Mirror" or a	Remote Mirror,
       there are different options available.  All options are available
       either as a commandline option to svnnotify or as a hash	key in
       SVN::Notify::Config (see	their respective documentation for more
       details).

   Working Copy	on Mirror
       Because 'svn export' is not able	to be consistently updated, the	sync'd
       directory must be a full	working	copy, and if you are running Apache,
       you should add lines like the following to your Apache configuration
       file:

	 # Disallow browsing of	Subversion working copy
	 # administrative directories.
	 <DirectoryMatch "^/.*/\.svn/">
	  Order	deny,allow
	  Deny from all
	 </DirectoryMatch>

       The files in the	working	copy must be writeable (preferrably owned) by
       the user	identity executing the hook script (this is the	user identity
       that is running Apache or svnserve respectively).

Local Mirror
       Please see " SVN::Notify::Mirror	" for details.

   Remote Mirror
       Used for	directories not	located	on the same machine as the repository
       itself.	Typically, this	might be a production web server located in a
       DMZ, so special consideration must be paid to security concerns.	 In
       particular, the remote mirror server may	not be able to directly	access
       the repository box.

       NOTE: be	sure and consult "Remote Mirror	Pre-requisites"	before
       configuring your	post-commit hook.

       o   ssh-host

	   This	value is required and must be the hostname or IP address of
	   the remote host (where the mirror directories reside).

       o   ssh-user

	   This	value is optional and specifies	the remote username that owns
	   the working copy mirror.

       o   ssh-identity

	   This	value may be optional and should be the	full path to the local
	   identity file being used to authenticate with the remote host. If
	   you are setting the ssh-user	to be something	other than the local
	   user	name, you will typically also have to set the ssh-identity.

       o   ssh-tunnel

	   If the remote server	does not have direct access to the repository
	   server, it is possible to use the tunneling capabilities of SSH to
	   provide temporary access to the repository.	This works even	if
	   repository is located internally, and the remote server is located
	   outside of a	firewall or on a DMZ.

	   The value passed for	ssh-tunnel should be the IP address to which
	   the local repository	service	is bound (when using svnserve).	 This
	   will	tunnel port 3690 from the repository box to localhost:3690 on
	   the remote box.  This must also be the way that the original
	   working copy	was checked out	(see below).

	   To tunnel some other	port, for example when using Apache/mod_dav,
	   ssh-tunnel should be	the entire mapping expression, as described in
	   the OpenSSH documentation under the "-R" option (remote port
	   forwarding).	 For most sites, passing "8080:10.0.0.2:80" will work
	   (which will tunnel port 80 from the repository to port 8080 on the
	   remote client).  If you are using SSL with Apache, you can use e.g.
	   "80443:10.0.0.2:443".

	   For example,	see "Remote Mirror Pre-requisites" and after step #6,
	   perform the following additional steps (when	using svnserve):

	     # su - localuser
	     $ ssh -i .ssh/id_rsa remote_user@remote_host -R3690:10.0.0.2:3690
	     $ cd /path/to/mirror/working/copy
	     $ svn co svn://127.0.0.1/repos/path/to/files .

	   where 10.0.0.2 is the IP address hosting the	repository service.
	   For the same	configuration when using Apache/mod_dav, do this
	   instead:

	     # su - localuser
	     $ ssh -i .ssh/id_rsa remote_user@remote_host -R8080:10.0.0.2:80
	     $ cd /path/to/mirror/working/copy
	     $ svn co http://127.0.0.1:8080/repos/path/to/files	.

       o   ssh-options

	   If you have any other options that you would	like to	pass to	the
	   ssh client (for example to change the default SSH port), you	can
	   pass	extra options using this parameter.  Be	sure that you pass it
	   a string that has ssh long option/value pairs separated by a	space,
	   or short options without any	space at all.  Internally, parameter
	   is split on spaces and passed in the	@Net::SSH::options array.

   Remote Mirror Pre-requisites
       Before you can configure	a remote mirror, you need to produce an	SSH
       identity	file to	use:

       1. Log in as repository user
	   Give	the user identity being	used to	execute	the hook scripts (the
	   user	running	Apache or svnserve) a shell and	log in as that user,
	   e.g.	"su - svn";

       2. Create SSH identity files on repository machine
	   Run "ssh-keygen" and	create an identity file	(without a password).

       3. Log in as remote user
	   Perform the same steps as #1, but this time on the remote machine.
	   This	username doesn't have to be the	same as	in step	#1, but	it
	   must	be a user with full write access to the	mirror working copy.

       4. Create SSH identity files on remote machine
	   It is usually more efficient	to go ahead and	use "ssh-keygen" to
	   create the .ssh folder in the home directory	of the remote user.

       5. Copy the public key from local to remote
	   Copy	the .ssh/id_dsa.pub (or	id_rsa.pub if you created an RSA key)
	   to the remote server	and add	it to the .ssh/authorized_keys for the
	   remote user.	 See the SSH documentation for instructions on how to
	   configure

       6. Confirm configuration
	   As the repository user, confirm that	you can	sucessfully connect to
	   the remote account, e.g.:

	     # su - local_user
	     $ ssh -i .ssh/id_rsa remote_user@remote_host

	   This	is actually a good time	to either check	out the	working	copy
	   or to confirm that the remote account has rights to update the
	   working copy	mirror.	 If the	remote server does not have direct
	   network access to the repository server, you	can use	the tunnel
	   facility of SSH (see	ssh-tunnel above) to provide access (e.g.
	   through a firewall).

       Once you	have set up the	various	accounts, you are ready	to set your
       options.
