What app are you talking about? Can you please be more precise, provide system details, software versions etc. and explain IN DETAIL what you’re planning to do.
App - Restrict login to IP addresses
There is an app on the market called “Restrict login to IP addresses” See link.
We are running NC 18.04
Running Ubuntu 18.04
In regards to the IN DETAIL comment, I want to use DDNS entries for whitelisting not IP addresses. I have several locations that do not have static IP addresses and therefore their IP changes. I have DDNS entries setup for for each of these locations. instead of using 127.0.0.1, I want to use myhome.home.com and have the DNS lookup the IP.
The server only see the ip and not the host.
Perhaps you can write software with a list fo dyndns-names that are changed to ip-addresses (e. g. host or nslookup).
You can use iptables but the man page do not recommend it…
--source address[/mask][,...]
Source specification. Address can be either a network name, a hostname, a network IP address (with /mask), or a plain IP address.
Hostnames will be resolved once only, before the rule is submitted to the kernel. Please note that specifying any name to be re‐
solved with a remote query such as DNS is a really bad idea. The mask can be either an ipv4 network mask (for iptables) or a plain
number, specifying the number of 1's at the left side of the network mask. Thus, an iptables mask of 24 is equivalent to
255.255.255.0. A "!" argument before the address specification inverts the sense of the address. The flag --src is an alias for
this option. Multiple addresses can be specified, but this will expand to multiple rules (when adding with -A), or will cause mul‐
tiple rules to be deleted (with -D). ```
