I am trying to connect to a remote server using the ssh

Question

But I am getting the following error:

ssh_exchange_identification: read: Connection reset by peer

I executing the following command:

sudo ssh root@example.net

Can this be due to somekind of firewall settings or because the server is overlaoded?

You don't need to sudo to ssh to another box as root, just ssh root@where-ever from your current id. You only need sudo if you're using key exchange as the root user. Also, never ssh into a box as root. Having said all that - try ssh -v -v -v root@whatever and see if you get any meaningful output (-v makes it more verbose).
Have you specifically enabled root logins over SSH? I know they're disabled in Ubuntu, and you really shouldn't be logging in as root via SSH anyways.

It's likely a firewall issue, I can connect fine from here (it asks me for a password).

Please do not use sudo ssh, just ssh is fine. Also, disable passwordbased authentication and use keybased auth if possible.

To diagnose problems, run ssh with the -v option (-vvv for maximum verbosity):

ssh -vvv user@host
