Using svn over ssh

I was delighted to find that connecting to a subversion repository on a remote server over SSH was quite easy on my Mac (windows may be another story).

All you really need to do is install subversion on the remote server, the subversion install contains something called svnserve that handles all the tunneling magic for you when you connect over SSH.

Now create a repository:

svnadmin create /home/svn/test

Now install the svn client tools on your box. Now you can checkout the repository:

svn co svn+ssh://your.remote-server.com/home/svn/test

That was much easier than I thought it was going to be!

I did run into a few permission issues but its pretty easy to fix those, you just need to make sure the user your connecting with over SSH has permission to read and write to the repository.

As I said connecting with windows may be another story, because windows doesn't come with a ssh command.

With Windows just install the free Tortoise SVN and that will give you context menus and icon overlays allowing you to perform checkouts, updates, commits and revision graphing etc. Installing Subversion without RPM, now that was the tricky bit :)
Richard, I've used SVN on windows (and Tortoise SVN), but I connected to my repository over webdav, not SSH. Are you saying that Tortoise SVN has a builtin ssh client?
Hi Pete, I think so, I didn't get time to set up WebDav so I'm just using svnserve. Just found this article which relates to the topic: http://www.logemann.org/day/archives/000099.html
HTTPS (via Apache2) is a better way to do secure remote access over SSH. As you've seen, SSH requires careful permission manipulation, but that's not the most troubling problem. svnserve operates directly on the repository files (using file:/// urls), which means if you ever have two svnserve processes running at the same time, you can get contention, which usually results in a locked repository that has to be taken offline, repaired, and reenabled. You'll run into the same issue if you combine svnserve and webdav access at the same time. Bottom line, webdav is the best bet, since it uses a multithreaded server that can handle concurrency without corrupting your database. Apache also supports authentication with client certificates, if you're concerned about security.
Barney, I think you mean SSL not SSH. I would have preferred connecting over Apache2 and webdav with HTTPS, but in this case I already have Apache 1.3 running, and can't use Apache 2 due to some other requirements, thus the SSH tunnel. Luckily I don't think I will need to worry much about contention in this case since I will mainly be the only one using it for now.
I did mean SSH, but did a horrible job wording it. "HTTPS is a better alternative than SSH" is what I should have said. I failed in my conveyance of "prefer HTTPS over SSH". You can still run Apache2 on a non-standard port. So Apache 1.3 on :80 for your web work, and then Apache2 on :81 (or whatever) for your SVN repositories. Not that it matters a whole lot if none of the SSH downsides are relevant, but for others who might come across this post looking for insight.
Thanks for your insight barney. In my case its not worth the overhead of running another server, but it might be for some.
There's a slight mistake in the syntax for the ssh connection string. You need to add in your username like so: svn co svn+ssh://username@your.remote-server.com/home/svn/test Same syntax as SSH uses. It's actually probably not a mistake because from the command line it will prompt you for the username, but if you want to use it with a tool like TortoiseSVN, you need to pass it all in at once.

Hi Brian, From the shell it will use your local username by default, in my case it was the same as the remote username so I omitted it. But thanks for pointing that out.
I have an svn repository running on a hosted server. I would like to administrator that repository using svnadmin tool. I have the information how to ssh to the server. What i am not understanding is after establishing the ssh connection how would i use svnadmin tool. For example I want to export the whole repository to my local hard so that I can import it into a local svn server. Any Help is appreciated. Vivek
Hi, Pete, svn+ssh:// works fine while opensshd listen on the default port 22, but how to make svn+ssh works while changed opensshd listen on port other than 22? svn+ssh://host:port/path dont work
This was SO MUCH FASTER than DAV. We are talking 5 minutes vs 60 minutes for large operations. Thanks!
georgexsh, add this line to the "tunnels" section of your config file in ~/.subversion/config ssh2222 = /usr/bin/ssh -p 2222 -l georgexsh Instead of using "svn+ssh" you can now use "svn+ssh2222" instead (just change "2222" and "georgexsh" to your SSH port and username, respectively).
How can i restrict the access permissions of the svn clients in the following way 1. Can create new folders in the repository 2. Update the files created by themselves 3. Can not delete a delete even if they themselves created it
We use svn+ssh but have a big problem with the server timing out. I thought I'd googled that the timeout problem was the apache server, but if we're using svn+ssn, apparently apache isn't used...

Why do I have a timeout problem, and is there some other way to access the repository that isn't subject to timeouts? With CVS, you could use ssh directly, and there was never a problem with timeouts.

In case you're not following what I mean with timeouts, if I do an svn diff or svn log or other command with lots of output, *and redirect (or pipe) the output*, then I (often) don't get it all. It's silently truncated.

As a work-around, I'm using script(1) and then doing the command without redirection. But that's terrible.
I want to know, if there is a svn co (checkout), from which user, it has been done and when?
how can i checkout from linux server to windows through svn..
please help me..

ok my working directory and the repository are both located on a remote server.

Can i still make use tortoise svn client on windows.I mean mounting my remote work directory and then making use svn.
