Re: [Fab-user] forward x11

[Jeff Forcier]

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['address@hidden']` 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

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
