http downloads on an Ubuntu VM

[leoos]

I have a number of Ubuntu Server VM's as my Casper distribution points serving via AFP and SMB on JSS 9.92

I also have Graham Gilbert's docker implemented BSDpy solution running for Netboot services on the VM's
https://grahamgilbert.com/blog/2015/04/22/getting-started-with-bsdpy-on-docker/

When I follow the instructions on this post to enable http downloads https://jamfnation.jamfsoftware.com/article.html?id=216

I get the following error
(98)Address already in use: AH00072: make_sock: could not bind to address [::]:80

I know that one of my BSDpy docker instances is already using port 80

I'm wondering is this as simple as changing the port apache2 is using

Or should I change the docker port?

This has all come about from an idea to do a quick test on http downloads in my Self Service as I am having issues whereby the file sharing points sometimes take forever (over 5 minutes) to load when running a policy from the Self Service app. Seemingly randomly, but mostly when I am at a user's desk trying to show them how to use Self Service. That's actually my my issue and I haven't had any luck finding any mentions of a similar issue on here

@O'Sullivan I'd change the Apache2 port.. NetBoot is a cranky thing.. so changing the port may just anger it.

You will have two issues.

1) Docker is indeed using that port already, so you won't be able to re-use it.
2) All ports on Ubuntu below 1023 are marked by the OS as "privileged". This means there's extra work needed involving "authbind" if you want to run a daemonised server instance on your server running, say on port 443.

This is now getting into heavy system admin territory.
