Instructions for setting up git server on Synology Diskstation

Configure Synology NAS as Git Server

Instructions for setting up a git server on a Synology NAS with Diskstation. Specifically, I am using a DS414 with DSM 5.0.

Set Up User and Folder

  • Create user gituser via Diskstation interface (with File Station and WebDAV privilages)
  • Add new shared folder called git (located at /volume1/git) with read/write access for gituser and admin. This folder will hold all the repos.
  • Install Git Server package via Diskstation

Laravel Quick Tip: Handling CsrfToken Expiration gracefully
Quick tip for handling CSRF Token Expiration - common issue is when you use csrf protection is that if

Handling it is simple, and is a good lesson for dealing with other types of errors in a custom manner.
In Middleware you will see a file VerifyCsrfToken.php and be tempted to handle things there. DON'T!
Instead, look at your app/Exceptions/Handler.php, at the render($request, Exception $e) function.
All of your exceptions go through here, unless you have excluded them in the $dontReport array at the
