SSH "ssh: Could not resolve hostname"

I seem to be flooding the forum with issues at the moment, but there a few things i need to sort on this box.
I have SSH server installed and setup. Its running on port 777.
I can connect to the server via connectbot on my android phone without issue.
When i try to connect via my laptop (mint 11) or vis the server itself (LMDE) using username@192.168.0.100:777 I receive an error
Code: Select all
ssh: Could not resolve hostname 192.168.0.100:777: Name or service not known
now if i connect using username@192.168.0.100 -p 777 it all works fine.
Why doesn't it work by specifying the port :777

It might be as simple as because the correct usage wasn't followed? This is what ssh throws back at me when I just type 'ssh' in the terminal window:
Code: Select all
administrator@asus-a8jn ~ $ ssh
usage: ssh [-1246AaCfgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec]
[-D [bind_address:]port] [-e escape_char] [-F configfile]
[-i identity_file] [-L [bind_address:]port:host:hostport]
[-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port]
[-R [bind_address:]port:host:hostport] [-S ctl_path]
[-w local_tun[:remote_tun]] [user@]hostname [command]
administrator@asus-a8jn ~ $
As per usage instruction, you are not supposed to add the port number (and it is not an option either) after
[user@]hostname unlike in the other options such as [-D [bind_address
:]port] where it gives you the option to supply a port number.
Just use [-p port] as per correct usage then.

ssh user@ip:port
e.g me@127.0.0.1:22
Is correct usage, or am i very much mistaken. I've done that on other machines, and it seems to be in common use around the web.

Well, it's a perception. But just because it's common throughout the web doesn't necessarily mean everyone
should follow suit. Apparently, ssh has its own standard as far as usage is concerned.

Ok but the problem is that NXserver will not connect when I change the port in both the ssh config and nxserver config. Which is odd as FreeNX never had a problem under the ubuntu edition.
