I upgraded to 12 via freebsd-update. Done this plenty of times before. Upgrade went okay, but after reboot I couldn't ssh out from the box. ssh -vvv shows that everything goes okay until the very end: debug1: Authentication succeeded (publickey). Authenticated to example.org ([1.2.3.4]:22). debug1: channel 0: new [client-session] debug1: Requesting no-more-sessions@openssh.com debug1: Entering interactive session. debug1: pledge: network debug1: client_input_global_request: rtype hostkeys-00@openssh.com want_reply 0 Fssh_packet_write_wait: Connection to 1.2.3.4 port 22: Broken pipe Tore my hair out trying to figure this out. A web search led me to this solution: Add this to ~/.ssh/config: Host * IPQoS throughput This is apparently due to a VMWare networking bug. Posting this in case anyone else had similar errors.
