To Whom It May Concern,<br>
<br>
Mosh is a great idea and piece of code. I use it on a daily basis to
re-establish connections on the fly. Any way, since we are big
believers of ipv6 at LSU, we have had a complete deployment of a
dual stack network for 4 years now. We are now beginning to start
deploying ipv6 only networks. In one such network that we are
testing, mosh did not work. I believe it is because it does not work
over ipv6 yet. This email is to put a bug in your ear to hopefully
steer you in that direction. We would e happy to test the code once
it supports ipv6.<br>
<br>
Below is basic output of me trying to connection to the mosh server:<br>
<br>
Try 1: only resolves for A records<br>
<br>
UNI-2:~ uni$ mosh <a href="mailto:jhandal@uni-tower.lsu.edu">xxxxx@uni-tower.lsu.edu</a>
