Description (last modified by ros)
Hi Andy,
When I ssh to puma I get the following message
:/users/anmcr> puma_ssh Warning: the RSA host key for 'puma.nerc.ac.uk' differs from the key for the IP address '134.225.0.17' Offending key for IP in /users/anmcr/.ssh/known_hosts:14 Matching host key in /users/anmcr/.ssh/known_hosts:15 Are you sure you want to continue connecting (yes/no)?
If I answer with 'yes' I can login to puma and am unable to launch the umui as the connection is rejected because of wrong authentication.
anmcr@puma:/home/anmcr> umui& [1] 14318 anmcr@puma:/home/anmcr> X11 connection rejected because of wrong authentication. Application initialization failed: couldn't connect to display "localhost:37.0" Error in startup script: invalid command name "option"
Can you please help?
Thanks,
Andrew

P.S.
You also need to make sure you're using ssh -Y or ssh -X to forward the X connection to your local machine.

Hi Andy,
Try removing the entries for PUMA in your /users/anmcr/.ssh/known_hosts file (lines 14 and 15) and then ssh into PUMA again to regenerate the entry. Hopefully that will sort things out.
If not let me know.
Regards,
Ros.
