dyndns's Issues

service failed: No such file or directory

Hi,

I just installed dyndns on my Ubuntu 20.04 box and tried to run it as a service after configuration, but I get dyndns.service: Failed at step EXEC spawning /apps/dyndns/dyndns: No such file or directory.
This is perplexing, because that file exists, of course:

root@mydroid:/apps/dyndns# ls -l /apps/dyndns/

What could be the problem?

username and password appear in journals

Rpi3b, bookworm. Client works fine.
This is only minor, but the username and password are in plain text in the config file. They also appear in the journalctl files and the systemctl status dyndns output. Perhaps these could be blanked, or the default logging not show all of this. These can both be seen by user pi, who is allowed sudo so it is not a big deal. For noip.com these are the username/password of the account; you can have 2FA on top of that but it seems a weakness.

Path is not absolute error

I'm trying to connect to FreeDNS.afraid.org but the service is erroring out and I don't know what to do. Running journalctl gets me this:

noah@beelink-server:~$ journalctl -u dyndns

This is the dyndns.service:

[Unit]
Description=Update External IP v4/v6 addresses to a Dynamic DNS server
Wants=network-online.target
After=network-online.target

[Service]
# Set the following USER to your user name.
User=noah
# Set the following WORKDIR to the source program directory (where you
# git cloned)
WorkingDirectory=~/dyndns
ExecStart=~/dyndns/%p

[Install]
WantedBy=default.target

I'm kinda new to this stuff so please help me, I'm trying to run a home web server and I got everything figured out except for the DDNS part, thanks!
