Package: mosh, sslh Severity: minor mosh can't be used on hosts that hide their ssh services behind sslh.
when connecting to such a host, mosh displays > mosh: Nothing received from server on UDP port 60001. then: > mosh: Nothing received from server on UDP port 60001. (... s without > contact) the problem seems to be caused by the way the ssh connection is established in sslh: sslh forwards the connection by creating another tcp stream from itself to the ssh server, causing SSH_CONNECTION have "127.0.0.1" in both source and destination ip fields -- and mosh, when started with -s, binds to the address it finds in SSH_CONNECTION. the mosh server seems to get started with -s automatically (even though the client seems to just call "mosh-server", it shows up in the process list as `mosh-server new -s ...`). several solutions seem feasible, in increasing order of my preference: * provide a way for the client to specify he doesn't want to use the `-s` option server-side (fix on mosh side) * have a server-side configuration option to turn off the `-s` flag for the host (better, as it has to be done only once per host) (fix on mosh side) * provide a way to find out the real address (fix on ssh side) as a workaround, i have provided a way around sslh for clients to connect directly, but that's not usually what an sslh user wants to do. -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.4-trunk-amd64 (SMP w/2 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages mosh depends on: ii libc6 2.13-35 ii libgcc1 1:4.7.1-7 ii libio-pty-perl 1:1.08-1+b2 ii libprotobuf7 2.4.1-3 ii libstdc++6 4.7.1-7 ii libtinfo5 5.9-10 ii libutempter0 1.1.5-4 ii openssh-client 1:6.0p1-3 ii zlib1g 1:1.2.7.dfsg-13 mosh recommends no packages. mosh suggests no packages. -- no debconf information
