Bug ID: 52693
Summary: Allow login using mosh as an alternative to ssh to
make labs usable at Wikimania
Product: Wikimedia Labs
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: Infrastructure

Classification: Unclassified
Mobile Platform: ---
ssh is quite painful over a slow and/or lossy connection. mosh uses ssh for
authentication and then changes to it's own robust, udp based protocol. Quoting
from the man page:
mosh (mobile shell) is a remote terminal application that supports
intermittent connectivity, allows roaming, and pro‐
vides speculative local echo and line editing of user keystrokes.
Compared with ssh, mosh is more robust — its connections stay up across sleeps
and changes in the client's IP address —
and more responsive, because the protocol is tolerant of packet loss and
the client can echo most keystrokes immedi‐
ately, without waiting for a network round-trip.
mosh uses ssh to establish a connection to the remote host and authenticate
with existing means (e.g., public-key
authentication or a password). mosh executes the unprivileged mosh-server
helper program on the server, then closes the
SSH connection and starts the mosh-client, which establishes a long-lived
datagram connection over UDP.
