Turns out the netstat response was referring to the V3 install, so killing all sc_serv didn't make a difference.
But checking on the license status I noticed that only the host name was listed with the IP address, instead of the FQDN. Checking the /etc/hosts file, it turns out I had the entry: IP host FQDN, instead of IP FQDN host.
After correcting that, I uninstalled, re-issued the license, and re-installed (but this time using the --deps option I found in the remarks of the install.sh file - which I didn't see in the installation manual).
On the control server, there was no longer the error, but under OS it did say something like: 'Information Unavailable,' though the uptime, load, etc was displayed.
Not sure if it just took time, or it was some of the nudging I was trying, but the next time I went back, the OS was displaying as well.
Now, both servers show in Hosts, Status, and Logs, but that's it. I have yet to find out how to manage the remote.
I tried creating a new user, but the remote server isn't included as an option.
I haven't searched the forum for this yet, I wanted to get the above posted, so I'll start another thread if I don't find anything. But hints and suggestions are welcome.
