<br>
Roger, just to make sure that I understand what you're asking, let me start<br>
by describing how I access the NUT server:<br>
<br>
1. As the NUT server is already powered on it has completed its start up<br>
sequence.<br>
2. On my Mint20 linux I start PuTTy in SSH and attach to the server which<br>
is at 192.168.1.100.<br>
3. Then on the terminal session that PuTTy starts I log on to the RPi:<br>
username, password.<br>
4. At that point I'm ready to start issuing commands. This is where and<br>
when I'd issue the script command that you have offered.<br>
<br>
I guess I'm not understanding what "your server setup command" should be.<br>
I looked at the manpage for script - I'm still learning all this - and<br>
understand what the script command is to do in capturing terminal activity.<br>
The -c argument is looking for "your server setup command"; that's where I<br>
am stumped.<br>
<br>
Thanks much.<br>
Bill Cole<br>

It's the ExecStart line in nut-server.service. In my nut-server.service setup I <br>
have:<br>
<br>
[Service]<br>
ExecStart=/sbin/upsd<br>
Type=forking<br>
<br>
so the script command for me would be:<br>
<br>
?script -a -c "/sbin/upsd" NUT.script<br>
