[Jlab-scicomp-briefs] ssh host key change for scilogin.jlab.org

[Bryan Hess]

On the June maintenance day, CNI updated the servers for scilogin.jlab.org, hallgw.jlab.org, and login.jlab.org.  As these are new servers, the ssh/PuTTy hostkeys for these servers was changed.  Since CNI changed the hostkeys, anyone that had previously accepted hostkeys for these servers will get a warning that the hostkey changed and that it may be an issue.  In this case, this is a known change and you can safely accept the new hostkey for the servers.  Please contact the JLab Help Desk if you have any questions or concerns about this change (helpdesk at jlab.org, x7155).


On Lix hosts, the old key can be removed with


      ssh-keygen -R  <hostname>

for example:

      ssh-keygen -R scilogin.jlab.org

and possibly

      ssh-keygen -R scilogin
