Goldstein Lyor reassigned SSHD-679:
-----------------------------------
Assignee: Goldstein Lyor
> Support (or ignore) IUTF8 terminal mode (42)
> --------------------------------------------
>
> Key: SSHD-679
> URL: https://issues.apache.org/jira/browse/SSHD-679
> Project: MINA SSHD
> Issue Type: Improvement
> Affects Versions: 0.14.0, 1.1.1, 1.2.0
> Reporter: Raman Gupta
> Assignee: Goldstein Lyor
> Labels: easyfix
>
> 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.
