Git Tags

Hi.

I have done this (on box A):

git commit -m "Message"
git tag -a 0.9.0
git push origin master

In my local repository, when I run "git tag" it is showing me "0.9.0".

Then I did (on box B)
git clone ssh://user@host:/path/project.git
cd project
git tag

Now git tag is showing nothing.

Why is the tag only available in my local repository?

Also when I try to
git clone --branch 0.9.0 ssh://user@host:/path/project.git
it tells me: fatal:remote branch not found in upstream repository origin

Why is the tag not available in origin?

Thanks,
Stefanie
