JASMIN login via ARCHER cray-mpich conflict error

Reported by: Leighton_Regayre Owned by: um_support

UM Version: <select version>

Description

In attempting to login to JASMIN so that I can transfer data from /work I'm given the following error:
Module 'cray-mpich/7.1.1' conflicts with the currently loaded module(s) 'cray-mpich/6.3.1'

after entering the command:
exec ssh-agent /bin/bash

I've previously had no problem logging onto JASMIN via ARCHER.

Thanks,

Leighton.

Was there a failure - this isn't an error message, its just for info? This message shouldn't affect logging on.

Grenville,

Yes there was an error after that step.

When I enter:
ssh -AX lregayre@…

I'm given the error:
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

I've set my paired keys as CEDA require and have copied the public key to myCEDA. I've logged in previously and have gone through this process again (~30 mins ago). Is there a problem we can tackle from our end?

Leighton.

Leighton,

If you are having trouble logging into Jasmin then you should contact the CEDA helpdesk by emailing support@…

Hello,

I have been in contact with the CEDA helpdesk over the past months and they have not been able to isolate the problem. Their jasmin experts have suggested that I login using:

ssh -o ServerAliveInterval?=300 lregayre@…

but this doesn't fix the problem. Sessions are still killed within a minute. CEDA helpdesk claim the signal is being killed from ARCHER. Has this happened to anyone previously?

Thanks,

Leighton.

I should have answered this better earlier, but had forgotten ARCHER policy; ARCHER does not allow outbound ssh sessions. You can only ssh into ARCHER.
