You can just set up an ssh server and run a central repository there. All developers then simply agree (as a matter of policy) to push to the server when they are done making commits. This is the usage pattern at my workplace. Very CVS and SVN-like.
/var/gitroot
for example).mkdir project.git && cd project.git && git init --bare --shared=group
).git clone ssh://yourserver.com/var/gitroot/project.git && cd project
)git add README
)git commit -m "Initial import"
), git push origin master
)This should set things up for you.
