Connecting to server from Terminal in Lion

Hello everyone, I was wondering what I need to type into terminal to connect to my server. I was only able to find one command and it doesn't seem to work. I have two Linux Ubuntu 11.10 (latestest version) servers and can connect to neither. Thanks in advance.

Here is the command I have been using. ssh username@server name.***.***.***.***
^^IP address^^

This all depends how you're trying to connect - what protocol are you connecting over? From the looks of it, you're trying to connect over SSH which is only going to work if the ssh daemon is started and configured on the Ubuntu box.

Second, you don't need the server name and the IP - stick with just the IP:

Well, If I'm not mistaken my network is dhcp, but I tried that in place of ssh and got a command not found so i switched back to the ssh thing at the beginning. I would I start/congifure the ssh on the ubuntu box? or is that not what I need to do with the dhcp network setting?

Where did you get the command not found?

How did you install Ubuntu? Usually when you do an install from a disc it installs the desktop version of Ubuntu - which doesn't provide most of the server stuff like ssh.

Note that if you expose ssh to the internet (i.e. open it in your firewall - you will be brute-forced attacked but scripts constantly) If you are just trying to access your computer internally behind your firewall - it should be fine to use passwords.

ssh username@ip should work fine. The first one you tried I wouldn't expect to work.

I installed it via USB, but it is the server version that doens't include the desktop environment. Essentially it's just the command line though a desktop mode can be enabled I believe . I tried ssh username@ip but it just adnvances the cursor to the next line. I'll try logging off the server and then see if that helps.

DHCP is not a connection protocol but a method of allocating IPs to clients. It has nothing to do with shares beyond giving machines on the network an IP address.

Ubuntu Server doesn't install SSH by default unless you explicitly select it during install (actually, I'm not even sure if it's an option - it's been a while since I installed it on my server). If you don't have it installed and configured, take a look at the Ubuntu server docs here. That's for version 11.10 - replace the version number in the URL with your version if you're using an older one.

I'm now running into the permission denied issue when transfering files from the mac to server. How can I fix this?

Have you successfully installed and configured SSH? Can you SSH in? If so, how are you trying to transfer the files (scp, sftp, smb, etc.)?

I got the SSH installed and connected to the mac via the mac's terminal (logged into the server) and executed the get filename command once in the files folder.

Can you be a little more specific? What command are you executing and on what machine are you executing it on?

Logged into the server I executed the get filename command. Here is an example

get document1.docx

I execute this when I am on the server remotely logged into the Mac & in one of its directories e.g. Documents.

Are you using FTP? I only ask because get is an FTP command. This is only going to work if you have FTP setup.

If you want simple file transfer, look into scp. Take a look at this.

Here's a simple example. Let's say I want to copy "test_document" from my Mac to my Linux server. I can execute the following to do this: That will copy test_document over to /home/vansmith on my Linux server over SSH.

yea, scp isn't as 'user friendly' as ftp. Although you can always pipe a tarball through ssh

True but it doesn't require any setup beyond an SSH account (which is already setup). The syntax is manageable as well if you think of it like cp.

I am using FTP which I setup. I'll try the SCP solution you mentioned as Vansmith.

You can always use cyberduck for ftp or sftp(ssh)

Good point. Cyberduck is a nice way to transfer files over SSH without having to know the commands.

As I understand it though, he's logged into the Mac from another machine:

If this is the case, we'll need to find another client (unless of course he's running this without X up).

Yeah the OP is a litte confusing. The original post said ubuntu servers - then as you quoted he is logged into the Mac through the servers. Anyway most file browsers in Ubuntu directly support sftp.
