Would be great to have SSH (portable) bundled with it.

hi

Does anyome know how to update this to use the latest verion 2.32.52?
I tried replacing the unison.exe but it comes up with an error. There has been quite a bit of development since 2.10.2 so it would be great to update.

Thanks

Does anyone know why Portable Unison triggers the "Are you sure you want to do this?" administrator warning in Vista? It's not doing anything at the system level, and so shouldn't need administrator rights to run... yet I haven't found a way to change the .exe file's security settings to run with out the annoying prompt. Is this just a result of the way that the file was compiled, and can the need for administrator rights be taken out in future updates? Thanks!

Just a tip for those wanting to use Unison with SSH. Unison profiles let you specify the port that SSH uses (default is 22).
Because many enterprises, especially Windows-shops, dont allow port 22 through their firewall, it is useful to use a different port (say, 80 which most companies have opened).

I do this to be able to sync files securely and encrypted from my laptop to my home computer. Even if Im behind a firewall somewhere, port 80 is always open to allow web access to the internet. When I sync with Unison, it calls SSH on my laptop which is configured to use port 80, contacts my home computer across the internet, and sends the files across the SSH encrypted tunnel.

The problem is this:
Although Unison 2.13 allows you to specify SSH URLs with a different port, some SSH for Windows implementations I've tried do not accept a -port parameter. So even if you specify port 80 in a Unison profile, SSH will default to port 22 and you get blocked by many firewalls.

The workaround is to configure SSH to -always- use port 80 by default. On my laptop, that means adding

Port = 80

in this file:

C:\Documents and Settings\myusername\.ssh\config

(create it if it doesnt exist).

Note that I havent tried or figured out yet how to do this with PortableUnison on a USB stick, but I foresee problems:

* SSH accepts a -F configfile parameter, which would allow you to save the config file on the USB stick, but Unison wont call SSH with that parameter

* Probably need to copy the SSH config file on the system you've inserted your USB stick

Has anybody managed to run PortableUnison from the USB stick, have it use SSH over a different port than the default port 22?

I just discovered PortableUnison and just wanted to say thanks for the effort. I've been using Unison to synchronize files between my laptop, home computer and NAS for years.

I know some people will be put off by it's less-than-stellar user interface, so let me just list some of the features which I think puts Unison above other file sync tools:

* Unison does -delta- synchronization, making it much more efficient than most other tools which simply use file date/time stamps for comparison.
Delta sync means it copies only the changed bits of files, not the entire files, when changes are detected. This means it is much more efficient especially over slow links.
So if I change -one- slide in a 80 slide presentation document, Unison will just send over the bits that represent that one slide (there are exceptions, especially with programs that write the entire file again every time you make a change)

* Unison does multi-master sync
Ie. it detects changes on both source and target sides, and can copy files over both ways.

* Unison does transitive syncs
Like stated in a previous comment here. Ie. I can sync my laptop to my stationary work computer, and have that sync to my home computer, and later sync my laptop with my home computer. It doesnt matter where changes are made, Unison handles things correctly

* Unison can use SSH
Granted, Secure SHell is used more in Linux and UNIX (ie. also Mac) environments than Windows. But SSH support means you get encrypted, authenticated file transfers

* Unison has a functional GUI
Its not -sexy- but it does do many of the things you want.

* Unison is cross platform
Ie. it runs on Windows, Linux, UNIX, Mac OS X, etc.

* Its FLOSS (free/libre open source software)

Oh wait, I probably need to do something like: http://www.cis.upenn.edu/~bcpierce/unison/download/releases/stable/unison-manual.html#ssh-win

This is what I get: Fatal error

Uncaught exception Unix.Unix_error(20, "create_process", "ssh")

does it need admin-rights on windows ?

I will wait for the author to contact me with a newer version for the portable wrapper. But I suspect you can just replace App\Unison\unison.exe with the latest version.

I had tried that "App" folder structure should be
unison\unison.exe
unison\*.dll
unison\bin\*
unison\etc\*
unison\lib\*
unison\share\*

I was able to run and use the app exactly as downloaded, without any modifications to files/folders for whatever it's worth. Great tool BTW! This is just what I need to synchronize my files with lab computers. (Compiling on flash drives = bad)

folders as present in Apps/GTK must be moved to Apps/unison, whereas all DLL's from bin must be moved to the same folder as the executable (unison) otherwise the tool won't run!
