problems submitting jobs from the new PUMA to Monsoon

UM Version: 7.3

Description

I followed all the advice in Andy Heaps' email (see below) and can ssh from PUMA to PUMA without needing a password. I deleted the references to PUMA in my known_hosts files on both PUMA and the ibm00. However, when I submit a job to Monsoon I get the following error message.

ERROR: Connection closed by lander.monsoon-metoffice.co.uk while attempting to access account kmemme on host ibm00. Note that repeated failures may result in expiry of password due to security procedures on some machines. Check user id, hostname and password for your account on the host machine.

I clicked 'OK' and resubmitted the job, but I continue to get this error popping up.

I'm also finding that I can't submit jobs to MONSooN — I get the following error (repeatedly, not just the first time I try):

ERROR: Connection closed by lander.monsoon-metoffice.co.uk while attempting to access
account zkipli on host  ibm00. Note that repeated failures may result in  expiry of
password due to security procedures on some  machines. Check user id, hostname and
password for your account on the host machine.

Investigating further, from the shell I started the UMUI, I can successfully ssh to lander.monsoon-metoffice.co.uk and thence to ibm00, but connecting back to PUMA fails prior to host-key verification:

I'm not sure whether this is due to a problem at the PUMA or MONSooN end though. (I have removed the old entry for PUMA from my .ssh/known_hosts on MONSooN; it worked correctly earlier this morning, and picked up the new key, but it can no longer connect.)

  • Resolution set to fixed
  • Status changed from new to closed

After a series of failed login attempts MONSooN got added to the list of denied hosts. This has now been fixed and job submission are working again.
