[gentoo-user] Layman adding git over ssh only repository

[Alexander Puchmayr <alexander.puchmayr@linznet.at>]

Hi there,

I tried to add a repository which is only reachable via git over ssh; no 
access via git port (9418 according to /etc/services) or http(s). Only ssh 
connections with public key are accepted.

I tried 
Layman -o ssh://git@myserver/path/to/repo.git -f -a myrepo, but failed with 
"invalid url".
Then I tried the same with "git://git@..." , also failed.

It seems like it does not accept the url scheme and refusing to connect at 
all. Next thing I tried is to create a repository.xml and put it to the local 
file system:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE repositories SYSTEM "/dtd/repositories.dtd">
<repositories xmlns="" version="1.0">
  <repo quality="experimental" status="unofficial">
    <name>my-repo</name>
    <description lang="en">My overlay</description>
    <owner type="person">
      <email>alexander.puchmayr#my-email.com</email>
      <name>Alexander Puchmayr></name>
    </owner>
  </repo>
    <source type="git">git://myserver/path/to/repo.git</source>
</repositories>

Layman -o repository.xml -f -a myrepo now tries to fetch it via the git port 
(9418), failing with timeout.

Replacing source type="git" with "ssh", "ssh+git", "git+ssh" also did not 
succeed. 

I'm pretty sure not being the first one trying this, but I cannot find any 
useful information how to do this. So how can I achieve this?

Thanks
    Alex
