If I download certain things it can be very fast, I/O is not an issue... terribly slow. I have the same issue, even with using port 80… really frustrating.

Here's what I did on my Debian/Ubuntu servers to change SSH's listening port: <code>sudo nano /etc/ssh/sshd_config</code> Change line: <code>Port 22</code> to: <code>Port 80</code> As an alternative you could also add a second <em>Port</em> line to have SSH listen on several ports: <code>Port 22Port 80</code> If you have a local iptables or other firewall running on the host, make sure the port is open. The same goes for EC2's global firewall. Finally, restart SSH: <code>sudo /etc/init.d/ssh</code> You also have to make this change in the clients. // Claus Hi David,

sorry for the late reply. Here’s what I did on my Debian/Ubuntu servers to change SSH’s listening port:

sudo nano /etc/ssh/sshd_config

Change line:

Port 22

to:

Port 80

As an alternative you could also add a second Port line to have SSH listen on several ports:

Port 22Port 80

If you have a local iptables or other firewall running on the host, make sure the port is open. The same goes for EC2′s global firewall.

Finally, restart SSH:

sudo /etc/init.d/ssh

You also have to make this change in the clients.

Or do I need to restart ssdh as well? Do I have to change all my clients to find this? Thanks. Dumb linux questions: Please help me accomplish this – is it just sshd -p80 on the server?
