We have recently migrated to Git from SVN. We have setup a bare repository on one machine in our LAN network and cloned on other machines. Now when anyone do the changes and commits we want that he sends the pull request to the bare repo (by telling or emailing or any other way) after that one will go through the changes and pull it on bare repository (same as it works on GitHub).

Do we need to install any interface or there is some commands in Git itself?
