OK, I am not embarrassed to ask... If I see some "weak" or "insecure" tags, what can I do about it? I have no idea how to disable MAC, key-exchange, and encryption algorithms used by the server I control. I had thought that just using SSH was "enough" More importantly, if I do disable the insecure stuff, what will it break ?

Ok, that's a very, very elementary stuff, how come do you don't that yet? Oh, Gosh, are you a programmer? For long how? :)))))

Earlier quoted context omitted.

Try any DNS name which only has a AAAA record, e.g. ipv6.google.com, which results in “An unexpected error occurred.”

Alright, thanks!

As an added note, your server seems to resolve some A record, despite no A records in the domain. I suspect whatever you're using for DNS does park all NXDOMAIN into some website of their own.

The fact you think that secures you, worries me, and that you share the almost exact setup you have with the world, just as much. Security is layers, and one layer is not telling the world about your setup.

Security is also not relying on obscurity to keep you safe.

having your server ssh exposed to the world and trusting your configuration is relying on obscurity. Having strict firewalls, with only a limited amount of trusted ip addresses is anything but relying on obscurity.

Call me critical AND paranoid.. but this kind of thing should be a tool people can run locally. Not via some public service, which is probably gonna be blacklisted on plenty of RBLs. However first and above all, SSH SHOULD NEVER LISTEN AND/OR RESPOND to non whitelisted ip addresses. NEVER, no exceptions. Also i think it is more a promotion for the rebex site and software, not so much the ssh scan utility... based on…

There are many cases when you don't know the IP you will be connecting from. The only way around that I know of would be a VPN, but SSH's auth and crypto strength is at least as good.

As long as people keep doing this, i will have a job cleaning up fuck ups. :)
