Step 5. Manage Sophos Using the Linux GUI (Default username: admin password: S0fO5)

Unlike the Windows and Macintosh installations, Linux does not have client software for accessing the local client install and configuration information. A web client has been built into the install package. For Ryerson users, CCS has set a default username and password. This means that with a web browser and the authentication information, a user can log into and control their Sophos client. 

Logging In to Linux GUI 

  1. Open your favorite web browser 
  2. Type in the URL: http://localhost:8081 
  3. At your first click you will be prompted for the Username and Password 
  4. Type in the default username: admin and type in the default password: S0fO5
