I think DDNS is still "a thing", but I believe the major providers 
started charging for even basic accounts. I'm not sure about this, just 
something rattling around the back of my brain.

Might not be necessary though, depending on your ISP and how often they 
change your IP.


Add an hourly or daily cron job doing something like:

curl http://bclug.ca/myip/ >> ~/myIP.log

Then check for how often the IP has changed:

sort | uniq ~/myIP.log

If your IP hasn't changed after a week, then the output should be one 
line with one IP address. Probably won't need DDNS then.


Another thing: who is your ISP?

You'll probably want your server to be able to send email notifications.

The options there are to set up a relay so it goes through another SMTP 
server, or to run postfix locally.

If running postfix locally, and on Telus, email won't send and it's hard 
to debug.

Your postfix will reach out and connect to a destination MTA, and ... 
nothing.  Telus blocks incoming traffic on port 25(?) and postfix will 
not be able to finish sending out mail.

TekSavvy allows this to work. Unsure of Shaw.



This led to quite an ordeal when my home server had both cable and fibre 
connections.

Had to script up something that rewrote the routing table such that a 
selection of major email providers' MX records got looked up for IP 
addresses, then those IP address routes were sent through cable, rest of 
traffic sent over fibre.

It worked...
