I recently upgraded my Macbook to OSX Mojave (10.14.1). Ever since I upgraded whenever I want to open an SSH session to any server on the internal (VMware) network I would receive the following error message:
packet_write_wait: connection to x.y.z. port 22: broken pipe
Very annoying as it made deploying labs in our dev cloud very complicated. I googled around and there were many suggestions on how to solve this, but none worked so far. A colleague today pointed me to thread on VMTN (surprisingly) which describes how to solve the problem. it is very simple, just add “ssh -o IPQoS=throughput” to your normal ssh command. So something like the following:
ssh -o IPQoS=throughput root@192.168.1.1
Thanks Alex for the pointer, and thanks Quinn for posting the solution on VMTN! Oh, and yes you can add the following to your ~/.ssh/config so that you don’t have the use the -o flag everytime:
Host * IPQoS=throughput
