Can you ssh with public IP?

Can you ssh with public IP?

Yes. You need to forward port 22 (or whichever port you’re running ssh on) through your firewall. In addition, I suggest doing a few things to make hacking more difficult, such as switching to a different port, allowing public key only, or limiting remote connections to certain IP addresses.

How do I enable ssh on a specific IP?

Now, perform the following steps to configure the IP addresses with authorization to log in by using SSH:

1. Open the file /etc/hosts.allow file by using a text editor: vi /etc/hosts.allow.
2. Add an sshd line to allow the IP address of your choice to connect by using public SSH.
3. Save and close the file.

Do you need a static IP for ssh?

All the users on the local machine will be able to use it. You’ll still need to fix your network so you can connect to it, but that doesn’t really have anything to do with ssh. If it has a public IP, then you can use something like dyndns.org and ddclient to get a dynamic name for it.

How is SSH used to connect to remote systems?

Using SSH public-key authentication to connect to a remote system is a robust, more secure alternative to logging in with an account password or passphrase. SSH public-key authentication relies on asymmetric cryptographic algorithms that generate a pair of separate keys (a key pair), one “private” and the other “public”.

Do you have to use public IP address for SSH?

If the computer you are trying to remotely connect to is on the same network, then it is best to use the private IP address instead of the public IP address. Otherwise, you will have to use the public IP address only.

How to connect to remote computer with public IP ADDR?

There are some conditions: – The computer, that you want to connect to, must have installed openssh-server. – There must be port-forwarding for the local IP address, in order to type ssh {Public IP ADDR} -p {Port number (default is 22)} if you want to connect to the remote PC.

Why is my SSH not open on my remote host?

Regarding your ssh output http://pastebin.com/dDxd4GjQ it seems like ssh isn’t open on default port 22 on the remote host. (possibly no ssh at all, or a firewall is protecting it). If you have authorisation, you can scan the ports of this host to see if there’s a binding ssh port on another port.
