If you wish to access your website via an SSH client you need to first enable SSH access. To do this, login to your control panel and select Manage Website from the websites box (if you have more than one website hosted with Gradwell you will have to choose the correct one using the dropdown box).
From the next page, select Web Hosting Settings.
The screenshot below shows that for this website SSH access is currently disabled (under SSH Access Configuration you can see that SSH access is set to off). To enable it, click Edit.
Tick Enable SSH-connections to this webspace.
You can now enter your desired username and password. If you need to edit this at a later date, simply return to this page.
Once you have enabled SSH access the IP address that you need to enter into your client will be displayed on the Web Hosting Settings page.
