Please expose more/all ports

[frankhommers]

Can you expose the ports 1001-65500 in your container?

This because I wanted to publish ports 33000 until 33100 for my container (ports in the range of 10000-10100) are used elsewhere. So I passed this to the container: -p 33300-33400:10000-10100

This works, but it gets very confusing:
I would start with this.

ssh -fN -R 10000:localhost:22 -p 2222 root@domain.tld

But I need to connect with this:
ssh -p 33300 user@localhost

That's really confusing. And exposing all the ports and just specify a few of them using -p will solve this problem.

I understand, but opening "all" ports (or more) will take a long time, so the range is some sort of a compromise between having enough ports and letting the container start within some sort of reasonable time frame. I don't really know what the best behaviour is here and you have a solution at hand (even though I admit it is a bit confusing...).

Extra thoughts?

[frankhommers]

Yeah. I could work with --net=host and move the sshd to another port. I'll check that.

[frankhommers]

I tried to run my docker with
docker run -it --rm --net=host --name rsshd -e PASSWORD=secret -v /data/rsshd/keys:/etc/ssh/keys -v /data/clients:/root/.ssh efrecon/rsshd -d -d -d -p 22222

but the -d -d -d and also the -p 22222 do not seem to reach the sshd arguments.

[efrecon]

hm.. Will have to look into this in more details then. You are welcome to debug if you want, arguments from the command should be passed to sshd as the last line of the entrypoint called sshd.sh.

[frankhommers]

Yeah I have seen that. Just a simple echo "$@" at the beginning of the sshd.sh will not show anything. I wonder if there is anything wrong with my installation.

[frankhommers]

The arguments don't work on my Synology as well as my MacBook. I'll just build my own docker to my specific needs.

[frankhommers]

BTW: Exposing all ports (1-65535) works just fine and fast. As long as you don't -p them all, there is nothing wrong with this.

BTW2: ENV ARGS also works nice for me.

I can put it in a PR if you like. But I can also just fork it and roll my own ;-)
