Hi Jeff,

I just built and installed the latest master (and next) and then I tried to clone (as I usualy do) one of my repositories. I run git-daemon only with the upload-pack service enabled.

On the client side this is the symptom:

client:~> git-clone git://server/srv/scm/linux-2.6.git Initialized empty Git repository in /home/user/linux-2.6/.git/ fatal: The remote end hung up unexpectedly fetch-pack from 'git://server/srv/scm/linux-2.6.git' failed.

On the server side I get this message:

xined.log:

07/11/20@10:17:04: START: git from=10.82.124.104 07/11/20@10:17:04: EXIT: git status=255 duration=0(sec)

messages:

And here is a small tcpdump snippet:

I'm not sure what other details would be relevant: tools versions, kernel version?

Did you try this and is working for you?

Cheers, Emil.
