1. Re: Changing a device's IP (Brian Kelly)
--- Begin Message ---
Thank you for writing back Oliver!
I’m not that versed in YAML but trying. Following your lead, the website docs,
and a lot of trial and error (including Deep recursion on subroutine
"App::Netdisco::Util::Permission::check_acl"), I _think_ I have something that
should work, but it doesn’t seem to.
In a nutshell, I’m looking for something to match Cisco ASA devices if they
have an IP in the 172.31.0.0/16 space on their management interface and if so
use the management IP for the device’s ID.
I posted in the IRC (https://kiwiirc.com/nextclient/irc.libera.chat/netdisco
<https://kiwiirc.com/nextclient/irc.libera.chat/netdisco>), but I’m probably
being impatient waiting for an answer or posted it in the wrong area (haven’t
used IRC in years), so apologies in advance.
Thank you again for a great product and looking forward to maybe even making
minor contributions in the future if I can!
BK
