[Fab-user] forward x11

[Vasyl Vavrychuk]

Hi,

Is it possible to do forward x11 for SSH connections established by fabric?
I mean equivalent of passing -X to ssh utility.

This would allow to run GUI programs from "run(...)" call by fabric.

Kinds regards,
Vasyl

Hi Vasyl,

It's technically possible, in the sense that our underlying SSH library
supports it, but it's not a well-tested feature even on that end and Fabric
doesn't currently offer high-level controls over that functionality.

You may want to dig around in https://github.com/paramiko/paramiko/issues/40
to see if any of the comments or links are immediately useful. You'd be
able to get access to the relevant Paramiko level 'guts' by examining
`fabric.state.connections`, whose values are Paramiko SSHClient objects (
http://docs.paramiko.org/en/2.3/api/client.html). (Simply requesting e.g.
`fabric.state.connections['***@hostname']` will trigger a basic connection
even if none exists yet - see
http://docs.fabfile.org/en/1.14/api/core/network.html#fabric.network.HostConnectionCache
)

Then call the client object's `get_transport()` method, and try messing
with the resulting Transport, such as calling its `open_x11_channel()`
method (
http://docs.paramiko.org/en/2.3/api/transport.html#paramiko.transport.Transport.open_x11_channel)
which
ought to bring you to a place where the info in that issue above, is
applicable.

Best,
Jeff
