The git daemon uses TCP to serve its data. If I use 'git clone' using the git protocol over a tunnel created with 'ssh -L', the clone works without any errors. The only thing that makes a difference is either tunneling via SSH or using the machine's onboard NIC instead (which uses if_fxp). Those two methods work fine. But using the NIC which utilizes the 'if_re' driver is not working properly. I'm not certain if it makes a difference, but the NIC is connected via a cardbus controller. It's also worth noting that this problem has never cropped up before using any other operating system, so it seems extremely unlikely to be a hardware issue. I'm not certain what data would be relevant for this issue, so please let me know what sort of debugging I should do to help narrow down the issue. And thank you in advance for your help! >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
