problem ssh'ing to puma

[anmcr]

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

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.

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 Ros,

Thanks for replying quickly.

It seems to have worked now.
