Everyone: I'm making my first FreeBSD 10.0 server, and have been trying to use scp to copy files onto it from a machine running 9.1. However, for some reason, transfers only work if I specify the "-1" option on the command line. The same is true of interactive SSH sessions; I can't log into either machine from the other with SSH Protocol 2. Has anyone else noticed this incompatibility? Here's an excerpt from the "verbose" output from a failed scp session in which I attempted a file transfer from the 9.1 server to the 10.0 server: debug1: identity file /root/.ssh/id_rsa type -1 debug1: identity file /root/.ssh/id_rsa-cert type -1 debug1: identity file /root/.ssh/id_dsa type -1 debug1: identity file /root/.ssh/id_dsa-cert type -1 debug1: identity file /root/.ssh/id_ecdsa type -1 debug1: identity file /root/.ssh/id_ecdsa-cert type -1 debug1: Remote protocol version 1.99, remote software version OpenSSH_6.4_hpn13v11 FreeBSD-20131111 debug1: match: OpenSSH_6.4_hpn13v11 FreeBSD-20131111 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.8p2 FreeBSD-20110503 debug1: SSH2_MSG_KEXINIT sent ...and then the transaction freezes until it times out. Sometimes, even specifying "-1" doesn't fully clear up the problems; multi-file transfers via scp still stall. The 9.x server has been fully updated to the latest patch version using freebsd-update(8). Anyone else seeing this? --Brett Glass
