TL;DNR ssh connection caching seems to cause git-annex to not work on NTFS volumes. Setting `annex.sshcaching` to `false` seems to solve the problem.
|
|
|
|
## What version of git-annex are you using? On what operating system? Please provide any additional information below.
|
|
|
|
* git-annex version: 3.20120629 on Debian Testing.
|
|
* `the-repo` is located on an NTFS volume on a USB HDD.
|
|
* `the-remote` is on the server `example.com`.
|
|
* `example.com` is running gitolite3 v3.2-19-gb9bbb78, git 1.7.2.5, and git-annex 3.20120629~bpo60+2

## What steps will reproduce the problem? What is the expected output? What do you see instead?
|
|
|
|
Create or clone a repo onto an NTFS volume.
|
|
Make sure `git annex` is initialized.
|
|
Run some regular git operations. These always seem to work.
|
|
Try git-annex operations.
|
|
|
|
Some operations work despite the error messages:
|
|
|
|
$ git annex sync
|
|
Control socket connect(/media/NTFSVOL/the-repo/.git/annex/ssh/git@example.com): Connection refused
|
|
Failed to connect to new control master

|

|
|

|
|
|
Some googling revealed the errors to be stale socket files.

It appears that SSH connection caching was implemented in response to this wishlist item:
|
|
[wishlist: Prevent repeated password prompts for one command](http://git-annex.branchable.com/todo/wishlist:_Prevent_repeated_password_prompts_for_one_command/)
|
|
|
|
However ssh connection caching breaks things on NTFS volumes. If I turn off connection caching, it seems to work fine
|
|
|
|
$ git config annex.sshcaching false
|
|
|
|
but it would be nifty if git-annex could detect the filesystem type and do The Right Thing.

Thanks for all the work on git-annex -- it's an awesome project!
