Can I use git protocol to push change to remote repo?

Can I use git protocol to push change to remote repo?

[Emily Ren]

Hello,

I can clone a remote repo with git protocol, but I can't push my
branch to origin repo with git protocol. If I use ssh protocol, I can
push sccuessfully. I'm confused, can someone give me a guide on this?
Can I use git protocol to push my branch to remote repo? If yes, how
can I do ? Thank you for your help in advance !

Error info is as below:
 $ git push git://host.xz/testgit check_push
fatal: The remote end hung up unexpectedly
error: failed to push to 'git://host.xz/testgit'

Successful info with ssh protocol:
$ git push ssh://host.xz/testgit check_push
user's password:
updating 'refs/heads/check_push'
  from 0000000000000000000000000000000000000000

Yes, git-daemon does not support pushing by default, since it doesn't do
any authentication of the pushing users. The recommended practice is to
push over ssh, which uses the exact same protocol, but is tunneled over
ssh, so the user is authenticated and the incoming data has an integrity
check (note that pulling by ssh is also the same protocol as pulling via
git://, except of course that it is also tunneled over ssh; this means
that if you are pushing and pulling, you can just set your remote to
talk to the ssh version).

If you _really_ want totally anonymous, unsecured pushing to your repo
(e.g., because you are on a restricted LAN and everybody is trusted),
you can enable the receive-pack service. See the git-daemon
documentation for details.

Peff,

Thank you for your help !  I read the git-daemon description, and
added following lines in the config file of remote repository.

 [daemon]
       receivepack = true

It failed with another error, is there anything I missed to config daemon ?
$ git push git://host.xz/testgit test_push2
updating 'refs/heads/test_push2'
  from 0000000000000000000000000000000000000000
  to   eebb60caae38a38361d002cdace043124a2fc871

unpack unpacker exited with error code
ng refs/heads/test_push2 n/a (unpacker error)
error: failed to push to 'git://host.xz/testgit'

Thanks,
Emily

Does the user running git-daemon have permissions to write to the repo?

Peff,

Yes, you are  right !  I changed the permission of the repo, and it's OK now. :)

Thank you very much for your kindly help !
