I had to update the TACACs server details on an old OmniPliance which proved to be quite confusing. I found the location of the settings but each time we restarted the service it reverted back to the way it was.
Quite a simple solution in the end… The procedure is below.
$ ssh root@omnipliance1 # service omnid stop # vi /etc/omni/engineconfig.xml
Edit the following line in engineconfig.xml
Quit with :wq! and restart the service.
# service omnid start
