Removing Outside Hosts/Networks from PIX 501

Let preface this question with a few know facts about me, I’m not certified and if it wasn’t for PDM, I would not be asking these questions.  I know just enough information from I what I have read to make me dangerous.  This PIX 501 had been configured by my network administrator before he went to a bigger and more rewarding position.

That being said, I have several years of experience within the IBM mid range systems and some network experience. Enough said, let me present my problem now.

While reviewing the configuration for our PIX 501 using PDM on the Hosts/Networks tab for the outside interface there were 2 addresses listed, one address is within the IP range assigned to us from MCI, the other one belongs to BellSouth  and we do not subscribe to their internet services. I attempted to delete the BellSouth IP address, but the system displayed the following message:

The host/network that you are attempting to delete is used in the following ways: SSH host. Please delete the appropriate information for these before removing this host/network.
What is SSH host and how is it accessed?  If this requires using CLI, I can select that option from the tools tab in PDM.  

I discovered this host/network entry because this Saturday I will be changing the PIX 501 to test our internet and access backup from Cox cable.  Currently we are using a CISCO 2600 router, PIX 501 and 24 port hub and it works great.

Your help will be greatly appreciated.

SSH is "secure shell". Similar to telnet but the data stream is encrypted.
In PDM, click Config button, System Properties tab, Administration tree, Secure Shell branch. If there is something listed in here, select it and delete it if that is what you want. Click Apply button at bottom and save when prompted by closing browser.
From CLI: sho ssh(enter). This will show you what is currently in there. config t will get you into configuration mode and exit will get you back out. write mem before you exit the session or save from PDM. For remote admin, use SSH or PDM.
SSH is built into most unix and linux distro's. I use putty in XP(or any windows for that matter). It is a free SSH client.
