<span style=" font-family:'Courier New'; font-size: 9pt;">Ohhhh... Very cool bash script, BTW.<br>
(my bash-foo is weak! Grasshopper will remember this tidbit!)<br>
<br>
I owe you a beer, or something!<br>
Thanks a bunch!<br>
<br>
[BTW, where/how do you determine what flag values to use - other than asking a dev? Is it documented somewhere other than just source code?]<br>
<br>
Again, thanks so much!<br>

You should see the word "reserved" added to the lease:<br>
<br>
lease 178.16.1.100 {<br>
starts 1 2020/07/20 14:00:00;<br>
ends 1 2020/07/20 15:00:00;<br>

cltt 1 2020/07/20 14:00:00;<br>
binding state free;<br>
reserved;<br>
hardware ethernet 08:00:27:25:d3:f4;<br>
set remote-handle = %1;<br>
}<br>

<br>
Perhaps I wasn't clear, but question #3 was about what I see in the leases file.<br>
<br>
After the lease is expired, here's what I find in the leases file.<br>
---<br>
lease 10.8.20.229 {<br>
starts 5 2020/07/17 22:42:54;<br>
ends 5 2020/07/17 22:42:52;<br>
tstp 5 2020/07/17 22:42:54;<br>
tsfp 5 2020/07/17 22:42:54;<br>
atsfp 5 2020/07/17 22:42:54;<br>
cltt 5 2020/07/17 18:42:52;<br>
binding state backup;<br>
hardware ethernet 98:01:a7:ff:ff:ff;<br>
uid "\000\000\000\000\000\000";<br>
set remote-handle = %3;<br>
set vendor-class-identifier = "MSFT 5.0";<br>
}<br>
<br>
---<br>
<br>
The only thing that I noticed that changed after setting flags was the<br>
set remote-handle = %3;<br>
And I can't find any detail about what "remote-handle" is.<br>
Does it even apply to reservations?<br>
<br>
TIA<br>
