does the git over ssh protocol tell the server the hostname?

Christoph Anton Mitterer· Feb 26, 2015, 23:14 UTC · lore

Hey.

Short question:

I saw that when plain git (i.e. git://) is used, the client tells the server the hostname specified on the client side. For http one has the same automatically via http's Host: header.

But after watching the git's over-ssh protocol, I couldn't find anything like that there? :-(

Would be quite nice to have this in order to implement vhosting like things.

Cheers, Chris.

No, it does not send the host name.

The host name in SSH that Git sees could be an alias in the user's ~/.ssh/config file that is rewritten to a different host. So virtual hosting keying off that could be confusing since the end user expects to have more control over it than they do with git:// or https:// where the host name is usually a DNS record the user does not control.
