rtems git readonly access behind corporate firewall

Hi,

I am attempting to use the RTEMS git repository but the following recommended command doesn't work.

> git clone git://git.rtems.org/rtems.git rtems

We have a corporate firewall here so it appears that I am forced to use one of the following commands instead (emphasis on http) after configuring the proper http proxy in git, but neither of these attempts are successful. There is an "rtems" but not an "rtems.git" at http://git.rtems.org/.

clone http://git.rtems.org/rtems.git rtems
clone http://git.rtems.org/rtems rtems

The first command above results in a the following message.

"warning: remote HEAD refers to nonexistent ref, unable to checkout."

The second command above results in long delays and eventually a message about the connection being reset by its peer.

I admit to being a git newbie so maybe someone will immediately recognize what I am doing wrong.

Jeff

Hi Jeff,

git clone http://git.rtems.org/rtems rtems works for me.

There were some problems earlier today in the RTEMS git repository.
You probably tried to clone when those issues were being solved by
Joel and therefore you got cloning errors.
Please try again. It should work.

Regards,
Cláudio

Also due to the repo being down the usual git clone was not working
using the git protocol so you might want to retry this as well.

FWIW cloning via http seems very slow even being on the
same local network as the rtems.org. It doesn't give much
feedback at all and "poof" it is done and there is code.

Hi Again,

I seem to continue experiencing some issues with the rtems git despite some potential fixes to the repository this am, but again I am a git newbie so I could easily be doing something dumb.

The first attempt below is almost certainly caused by the local corporate firewall, whereas the 2nd and 3rd attempt specify http to avoid that issue, but are nevertheless unsuccessful. I did also configure the local http proxy address into the local git client.

hill@ubuntu:~/nios2-rtems/rtems/rtems-git$ git clone git://git.rtems.org/rtems.git rtems
Cloning into rtems...

hill@ubuntu:~/nios2-rtems/rtems/rtems-git$ git clone http://git.rtems.org/rtems.git rtems

Thanks Joao (and everyone else for their answers),

I just now sent a request for a port 9418 firewall exception to the IT department here.

However, I read that modern git should work fine over http so I suspect that this “warning: remote HEAD refers to nonexistent ref, unable to checkout" might be a clue concerning what might be wrong (with the http based access).

Note that there can be two different ways to start the git clone.

git clone git://git.rtems.org/rtems.git rtems

git clone http://git.rtems.org/rtems.git rtems

Jeffrey,

I had the same problem in my corporate computer, I was unable to access GIT, and I tried many ways to solve the issue. In fact, it was not a proxy issue, but the corporate firewall used to block the GIT port. After some fights with the IT Team, the problem was solved.

The port is 9418. Check this out...

FWIW, I was successful with this request after the local IT department unblocked 9418.

git clone git://git.rtems.org/rtems.git rtems

Thanks to everyone for their suggestions.
