I've just installed gitosis to my DS210j (3.1-1742) and want to add some advice to all, who wants to do it too.
After standart 'ipkg install gitosis' you need to do additional steps:
Change some lines in /etc/ssh/sshd_config:

Code: Select all

PubkeyAuthentication yes
AuthorizedKeysFile      .ssh/authorized_keys
PermitUserEnvironment yes
AllowUsers gitosis root admin


Now, copy SSH public key from client computer (let's call it my_client) to NAS (i.e. to /volume1/BackUp folder)

Code: Select all

[client] $ scp ~/.ssh/id_rsa.pub root@NAS_IP:/volume1/BackUp/my_client.pub

Now add this public key to authorized_keys on NAS, set .ssh/environment file (to prevent "gitosis-serve not found" error), init gitosis' keys and change mod to post-update.

Code: Select all

[NAS]
mkdir -p /opt/share/gitosis/.ssh
cp /volume1/BackUp/my_client.pub /opt/share/gitosis/.ssh/authorized_keys
echo "PATH=/opt/bin:/opt/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/syno/bin:/bin:/sbin:/usr/local/bin:/usr/local/sbin" > /opt/share/gitosis/.ssh/environment
sudo -H -u gitosis /opt/bin/gitosis-init < /volume1/BackUp/my_client.pub
chmod 755 /opt/share/gitosis/repositories/gitosis-admin.git/hooks/post-update


New system user (gitosis) does not have password, so you need to change it. It's not quite simple, because this user is not visible in web interface and there is no passwd command since DSM 3.0. I just edit /etc/shadow file and copy line from another user:

Code: Select all

andrey:*******************:*****:*:*****:*:::
gitosis:*******************:*****:*:*****:*:::

In other case you will get this error message during ssh connection:

Code: Select all

[client] $ ssh gitosis@NAS_IP
Connection closed by NAS_IP
[NAS] > tail -n 2 /var/log/messages
Jun 13 11:29:20 sshd[7243]: pam_winbind(sshd:account): pam_winbind_request: write to socket failed!
Jun 13 11:29:20 sshd[7243]: pam_winbind(sshd:account): internal module error (retval = 3, user = 'gitosis')


Now you must reseive such responce:

Code: Select all

[client] $ ssh gitosis@NAS_IP
ERROR:gitosis.serve.main:Need SSH_ORIGINAL_COMMAND in environment.
                                              Connection to NAS_IP closed.


And you can now manage gitosis:

Code: Select all

[client] $ git clone gitosis@NAS_IP:gitosis-admin.git

Thanks for posting this. I'm running DSM 3.1-1613 on a DiskStation 1511+. I followed your directions, but when I changed the /etc/ssh/sshd_config file to allow 'PermitUserEnvironment', DSM failed to restart the ssh service via the DSM web interface. I had to telnet in to change back the sshd_config file so that SSH would start up again on my Synology. Do you know why enabling 'PermitUserEnvironment' causes SSH not to restart on the Synology?

Thanks for your time and help!
