> My version of openssh running on Fedora 23 is:
> OpenSSH_7.2p2, OpenSSL 1.0.2h-fips  3 May 2016
> When connecting to an sshd server using this client, the client transmits terminal mode
42 (IUTF8 terminal, see https://tools.ietf.org/html/draft-sgtatham-secsh-iutf8-01).
> The server however does not define this mode and breaks out of the loop processing the
client terminal modes with the warning:
> Unknown pty opcode value: 42
> As per the spec (https://tools.ietf.org/html/rfc4254#page-19) only opcodes 160 to 255
should cause parsing to stop. Other opcodes, if not understood by the server (such as opcode
42) should be ignored. However, currently opcodes less than 160 cause parsing to stop as well.
