Tiny LXC box

anteck

I have one of these that doesn't permit a TUN interface, which kind of nixes the VPN idea I had in mind.
Net speeds are actually pretty impressive for such a small unit, albeit IPv6 only.
Apart from web hosting or a DNS server, what other uses could I put this thing to?

You can try squid proxy server,
Nice network speed.

Whoops, I've ran into a problem here:

ssh root@<IPv6 address assigned>
port 22: Network is unreachable

Any suggestions...?
This is an IPv6-only box, whereas my other IPv4 instance connects just fine.

Is it listening on port 22?
Does your internet provider give you access to the IPV6 internet (or are you using some method to get from IPV4 to 6)?
What happens if you

ping6 2606:4700:4700::1111 ?

Ask for TUN/TAP to be enabled.

Asked already...and declined...

No problem with IPv6, once I have an IPv4 connection set up through OpenVPN...
Close that VPN connection and guess what...?
$ ping6 2606:4700:4700::1111 connect: Network is unreachable

Supplied by the provider:
Primary IP 192.168.52.22

My initial thinking is that the network interface initialisation, client side, might be the primary issue....

@anteck - I'm all confused here.

Do you have IPv6 connectivity? Otherwise I'm not surprised that you're unable to SSH to the IPv6 box. That also explains why once you enable OpenVPN things work (likely you have all external connectivity routed via the OpenVPN tunnel).

anteck

I guess I don't have independent IPv6 connectivity at all.
Just like you say, only when OpenVPN is up and running...

@anteck said: I don't have independent IPv6 connectivity

I guess that explains it then.

You should check if there is a IPv4 NAT for the LXC box which will allow you to use a custom port to SSH via IPv4.

Otherwise, if you want to reach the IPv6 only box you should look at a ProxyCommand and/or ProxyJump options for SSH (assuming a recent enough version of SSH).

You could use it as a honeypot to combat malicious online activity.

anteck

Oh dear, back to the old drawing board...
I'll take a look into the SSH proxy options available.
Thanks to all for your help...!
