I feel silly for not realizing that the SSH config would be used by Git!
I thought if Forgejo’s SSH service listened to a non-standard port that you would have to do commands with the port in the command similar to below (following your example). I guess I assumed Git did not directly use the client’s SSH service.
git pull [email protected]:1234:user/project.git
There are plenty of valid reasons to want to use a reverse proxy for SSH:
Regardless of the reason, your last point is valid and the real issue here. I do not think it is possible for Caddy to reverse proxy SSH traffic - at least not without additional software (either on the client, server, or both) or some overly complicated (and likely less secure) setup. This may be possible if TCP traffic included SNI information, but unfortunately it does not.
people often seem to have a misinformed idea that the first item on your dns server list would be preferred and that is very much not the case
I did not know that. TIL that I am people!
Do you know if it’s always this way? For example, you mentioned this is how it works for DNS on a laptop, but would it behave differently if DNS is configured at the network firewall/router? I tried searching for more info confirming this, but did not find information indicating how accurate this is.
Depending on the network’s setup, having Pihole fail or unavailable could leave the network completely broken until Pihole becomes available again. Configuring the network to have at least one backup DNS server is therefore extremely important.
I also recommend having redundant and/or highly available Pihole instances running on different hardware if possible. It may also be a good idea to have an additional external DNS server (eg: 1.1.1.1, 8.8.8.8, 9.9.9.9, etc.) configured as a last resort backup in the event that all the Pihole instances are unavailable (or misconfigured).
The steps below are high level, but should provide an outline of how to accomplish what you’re asking for without having to associate your IP address to any domains nor publicly exposing your reverse proxy and the services behind the reverse proxy. I assume since you’re running Proxmox that you already have all necessary hardware and would be capable of completing each of the steps. There are more thorough guides available online for most of the steps if you get stuck on any of them.
This would only work if there is no other traffic on the port being used (eg: port 22). If both the host SSH service and Forgejo SSH service expect traffic on port 22, then this would not work since server name indication (SNI) is not provided with SSH traffic and Caddy would not be able to identify the appropriate destination for multiple SSH services traffic.
Are you able to provide some details on how you are doing this? I don’t think you can do much with reverse proxies and SSH beyond routing all traffic on port 22 (or the configured SSH port) to whichever port SSH is listening on. In other words, the reverse proxy cannot route SSH traffic for the host on port 22 to the host, route SSH traffic for Forgejo on port 22 to Forgejo’s SSH process, and SFTP traffic on port 22 to the SFTP process - at least not via domain name like a HTTP/HTTPS reverse proxy would work.
Instead, this would need to be done via IP address where the host SSH process listens on 192.168.1.2, the Forgejo SSH process listens on 192.168.1.3, and the SFTP process listens on 192.168.4. Otherwise, each of those services would need to use different ports.
I believe the reverse proxy settings in your post is just configured to handle the http/https connection, not the SSH connection. Instead, SSH connections are likely being routed to the machine running Foegejo via DNS and your reverse proxy is not involved with anything related to SSH.
I assume you either have SSH disabled on your host or SSH on your host uses a port other than 22?
I do not think what I would want as a replacement exists (yet). My main requirements are:
I think the closest I have seen is LibreELEC + Kodi on a RaspberryPi or mini-pc. It’s still not quite there for my tastes though. Hopefully the recent Chromecast announcement will lead to more/better alternatives in the coming months!
Open source projects still need a maintainer/owner. For example, Facebook “controls” react, Microsoft “controls” Visual Studio Code, and AdguardTeam “controls” AdGuardHome. There are several reasons to not trust a maintainer (eg, license changes, prioritizing or implementing undesired functionality and anti-features, converting to “open core”, abandoning the project, selling out to less trust worthy entities, etc.).
Per Adguard’s website, the legal entity behind the various AdGuard products is
ADGUARD SOFTWARE LIMITED. A quick search on that company shows that there are 3 founders and they seem to have some ties to Russia. There is more information online about this, but whether this means they can be trusted or not is up to each potential user of one of the AdGuard products.
