If you make a symbolic link to the executable, you can edit the properties box to make this window come up iconic. That way when you click on the link, you seem to just get a unison window except on the task bar, where the text window shows. Roots are native filesystem paths; the others are root-relative. I ran in to some difficulties trying to use this ssh client with Unison, and tracked down at least one of the problems.
If you launch Unison from bash, it fails at least for me. My guess is that this is caused by some incompatibility between the Ocaml Win32 library routines and Cygwin with regard to setting up argv for child processes. Martin Cleaver has written up a set of instructions here.
This appears to be a problem with the Cygwin DLL version 1.

Downgrading to DLL version 1. To downgrade using the Cygwin setup program, run Cygwin's setup. Uh oh Michael writes, later: Actually, I've been communicating with one of the people afflicted with this bug and I think my solution is out of date. It looks like the new Cygwin DLL still has the bug, but the Cygwin setup program only lets you downgrade one version--now you can choose between 1. Karl Crary has a different workaround for this problem, using socket connections and port forwarding.
The key idea is to create a script looking like this:. In order to make syncing a particular profile "clickable" from the Win98 desktop, when the profile uses ssh, you need to create a. I first tried the obvious strategy of creating a shortcut on the desktop with the actual command line "unison profile-name", but that hangs. Brian Mork increa. The result is a single-click Unison icon synchronization on the desktop that you can click and walk away.
Implementations of the FAT32 filesystem may have limitations not only on the lengths of individual file names, but also the length of full path names of the file characters, I think? When Unison is in the process of syncing, it performs its work in a new subdirectory, increasing the total path name length of your files. If your files are already pushing the limits of FAT32, your unison operation may abort. Giving your files or directories shorter names may help to avoid this problem. So syncing between NTFS and FAT32 while preserving modification times may result in the file properties of all your files being updated on every synchronization.
This may be corrected in a future update of unison by ignoring such 1-second differences. This is very similar to the instructions referenced elsewhere on this page by Martin Cleaver see: How can I get Unison to talk through a Putty link on Windows? Another layer of encryption doesn't add anything of value.

Do this even if you do not intend to use relative addressing as this environment variable must exist. TIP: shorten and change the name so that it is easier to deal with.
I use unisont. This should echo to the screen the version of Unison. You will tell Putty itself via the Session screen the host name or host ip address and the port number, along with the protocol ssh. TIP: Once you have filled in the host name, select 'Save' to save the putty session information. This will be useful later. Then, click 'Open' the connection.
At that point, it should first display a relatively long message window and give you the option of establishing the connection even though there is no registry or cache that matches the server. Putty then opens a dos window and presents you with a login prompt. Use the username and password you established in step 3, above.

If the username and password are accepted, you will be presented with a dos prompt for your server. Type 'exit' to terminate the connection. I used plinker. As has been noted in other tutorials, the " " sign is critical. Where I have typed mypassword , use your password. Where I have typed myusername , use your user name. Where I have typed mysavedputtysession , use your saved putty session name. Here is a test profile that I used successfully, which I named profiletest. Where I typed remoteipaddress you can enter either the ip address of the server e.

I used the following command line:. Remember that I renamed the Unison executable to unisont. After a lot of mucking around and experimentation I got Unison's native ssh transport working from one XP host to another, so I thought I'd mention a couple of items against which I was banging my head a while, to save others the pain. Sorry I don't have time nor a posting place for a full cookbook-style howto. I also used Putty for testing, but now I believe it's not used at all in my final setup.

One key item is that the unison executable should either:. I chose the latter so I wouldn't have to worry about remembering to upgrade Unison in two locations later on. My "unison root" was on a different drive from my SSH server's executables, and I couldn't get it to work re-installing COPSSH to the D: drive - I really noodled around with this for hours, was on the verge on experimenting with NTFS "junction links" which would require converting the filesystem of my target drive, but while I was waiting for my backup to complete before going ahead, I hit upon - well, here's my batch file:.
Note the drive letter syntax in the target URI; unisong. Now works like a charm, secure yet convenient. Wasn't able to get key-based authentication working, still have to put in my password every time, but that's NBD. Take good notes and create self-documenting batch files as you go along, and of course backup your "live" data set before you start. In fact, I reckon don't rely on this automated sync routine as your main backup process - have a completely separate one doing regular snapshots so you can roll back any mistakes, with Unison or elsewhere - I'm using Ghost 12 set to run in the background every couple of hours during the day.
These instructions are for solving a specific problem: synchronizing data data between two Windows computers using SSH to access a central repository on a Linux Debian Testing server that is listening on a nonstandard port in this example the port is These instructions are similar to the section above many thanks but have been repeated here in their entirety for clarity. These instructions assume that the SSH server is already setup and functioning correctly. It also assumes that the Unison command line binary is installed on the server.
This is important because part of the syncing process launches Unison on the server to facilitate communication. The following steps should be carried out on each of the Windows clients. Download and install PuTTY. You want the Windows installer with everything, of course. This lets you answer the question about accepting the server's key. Download and unzip Unison. You can put the. My Debian server currently runs version 2.
It is critical that the server and the client run the same version at least the same major and minor numbers. Otherwise they will simple refuse to communicate. Of course, this is only important if you want to use the gui. Run the Unison gui and create a new pair. You'll notice that when you select SSH for the remote location the port section is ghosted. But not to worry, we'll take care of that later. Edit the. A sample.
