Using PuTTY on a PC for SSH Access to BGLinux


How do I use PuTTY on a PC for SSH access to BGLinux?




In order to create a new profile in PuTTY, you must fill out the following fields in the Session menu:

  • Host Name (or IP Address) -
  • Port - 22
  • Connection Type - SSH
  • Saved Sessions - bglinux (or any other name you wish to save this profile to)

You also need to enable X11 forwarding. 

  1. Click the + next to SSH in the Category window and click on X11 to highlight it
  2. Select the checkbox to Enable X11 Forwarding
  3. Select Session in the Category menu to return to the original screen
  4. Select Save and your new profile will be added to the list 

Logging In

Log into BGLinux (open your saved profile)

  1. Verify Session is hightlighted in the Category box.
  2. Locate the Load, save, or delete a stored session box and select the profile you wish to open (e.g. bglinux) to highlight it.
  3. Select the Open button to start your session.

The first time you open a profile you may receive a message box similar to below:

  1. It indicates that you are making a connection a different system with the name BGLinux.  
  2. Since the system has been upgraded, press the Yes or Accept button to continue on to your session.  
  3. You will not be asked again the next time you connect. 

PuTTY Security Alert. WARNING - POTENTIAL SECURITY BREACH! The server's host key does not match the one PuTTY has cached in the registry. This means that either the server administrator has changed the host key, or you have actually connected to another computer pretending to be the server. The new rsa2 key fingerprint is: ssh-rsa 1024 bb:8d:63:3f:1e:38:5f:f3:d3:7c:33:66:cc:58:ba:96. If you were expecting this change and trust the new key, hit YES to update PuTTY's cache and continue connecting. If you want to carry on connecting but without updating the cache, hit NO. If you want to abandon the connection completely, hit Cancel. Hitting Cancel is the ONLY guaranteed safe choice.
