Re: [ptp-dev] Queue support and tunnelling

Roland and Greg,

Thanks for the pointers. I'll dig into it and follow up.

Hi,

I recommend not to use tunneling but ProxyCommand/StreamForwarder instead. It has two main advantages:
- it is securer (with port-forwarding any other local user can use the connection)
- it works even if the server has port-forwarding disallowed (e.g. the login server at ORNL)

has this implemented with StreamForwarder.
I implemented this beforeĀ https://bugs.eclipse.org/bugs/show_bug.cgi?id=345329 as ProxyCommand. But I think the StreamForwarder solution is simpler, doesn't require an extra process, and doesn't require the user to specify the command (netcat or equivalent). The only disadvantage of StreamForwarder is, it is a bit less flexible (one can't do crazy things like multihop with http proxy behind ssh gateway).

If anyone wants better support for ssh proxy, let me know on 345329. Should be easy to add.

Everyone,

We've been using the PTP to establish remote connections and launch jobs for about a year now and we are finally ready to add support for queues and SSH tunnelling. Is there support in the PTP for this? That is, are there operations I could call to establish tunnels and maybe some way I could designate that a particular job should be submitted to the queue instead of launched in the shell?

Thanks very much,
Jay
