Greetings.
I just finished setting up the 1.3rc2 version of netreg and I wanted to toss
you guys a few comments:
I'm running it on redhat 8 (for your information)
I noticed a problem with refresh-dhcpdconf if the PID file for dhcpd doesn't
exist.. it just seems to bomb out of the script without making a .conf.bad and
without trying to start the dhcpd again.. At first I thought this meant it
wouldn't work at all, but I just noticed that it's been up for a full day now,
and it created a .bad file so I'm not sure what fluke of circumstances made it
fail for me in the beginning..
I added a feature to my copy of the admin.cgi so that you can manually add a
registration, which was a feature I thought would be in this version by now..
Some other features I'd like to see included in the admin.cgi are:
- Tail of error files (dhcpd.conf.bad and register-errors.log) so that you can
see from the web what has been going wrong
- archive the leases file so you can search a history of who had what lease
when (useful for when there are 2 week old accusations of copyright violation)
anyhow, thanks for your time..
I'm gonna paste in the hackjob I created for the manual reservation.. I'm sure
it can be cleaned up if you want to include it in a future version of netreg..
