Hello Kin (and group), I am now getting thoroughly confused by the recent flood of messages 
about bad IPs in PC92s and other related topics...!

A couple of weeks ago I followed previous guidance and included the following in the startup 
file for the GB7DXC-5 node:

set/var $main::localhost_alias_ipv4 = '90.155.35.170'
set/var @main::localhost_names qw( 127.0.0.1 ::1  192.168.1.90)

The address 90.155.35.170 is my public one, and 192.168.1.90 is the address of the 
Raspberry Pi-based GB7DXC-5 node on my LAN.  Both addresses are static.

I also downloaded version 1.2 dated 20250322 of Kin's update_ip.pl and put it into 
/spider/local_cmd, as per the instructions at that time.

I subsequently added the following to my crontab, to run update_ip.pl once a day at 0445, 
even though neither the WAN nor the LAN IP address should ever change:

45 04 * * * run_cmd("update_ip")

I now find that the GB7DXC-5 node is apparently misconfigured and is identifying itself as 
having address 127.0.0.1 and is also forwarding user information with LAN IP addresses 
(127.0.0.1 etc).

My question is what do I now need to do on the GB7DXC-5 node to correct whatever 
misconfigurations exist; I would be grateful for a step-by-step explanation in as simple 
language as possible, please - I am not a Linux expert...!

To confuse me even more I've recently noted that there is a reference to putting Kin's latest 
version of update_ip.pl into the local_cmd/set directory, which doesn't exist on my system.  
I've also seen references to local_cmd/show, which also doesn't exist on my system.  Can 
someone please explain how to create these directories (mkdir?) and also provide a list of 
what they should contain, in addition to the latest update_ip.pl file.

Thank you in advance,

73,
