[ptp-dev] Shared sessions for SFTP

[Kevin Huck <khuck@xxxxxxxxxxxxx>]

Howdy all -

Quick question about how the Eclipse PTP Resource Managers connect over ssh...

I am surveying Eclipse PTP support on remote systems, and I have run into an interesting problem. I find that I cannot connect to the Cray XK6 (Jaguar) at ORNL through the System Monitor perspective, because they have administratively disabled shared sessions over ssh.  I get the following error:

Opening SFTP connection failed. Does the remote machine support SFTP and multiple sessions? MaxSessions for the SSH server has to be set to at least 5. channel not opened.

For other systems, I have (in the past) explicitly enabled shared sessions in my .ssh/config to prevent having to enter an OTP for each connection, and after disabling this feature in my .ssh/config, I find that it still works, so it must be built into Eclipse PTP now - which is great!

However, on Jaguar I am still stuck.  I don't suppose there is any way around this?

Thanks -

Kevin
