Here is the emergency I have.
I have a SCOUNIX box that does multiple things including the credit card processing through RITA. Evidently when they run a cc, it is not able to get out to be processed. This is also being used as a small email server as well. We have no problems with email on this box just getting out to process the cc. In the system.log file we get a "UNKNOWNHOSTEXCEPTION" error message and what I was told we need to edit the HOST file which is located under /etc directory. How do you edit this file? I try using vi host but I just get garbae. If I use cat host I can see whats in the file but can not edit the file. What I am trying to edit is the ISP and DNS addresses. I was told we need to put the ISP first and than have our DNS settings in there next.
I do appreciate it.!
