 The unknown host
I wasn't sure about the unknown host part.
I modified the host file according to 2 different threads, which worked on my other FC4 box usingthe FC3 zim installer.
It reads:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost mail.zim.bscbellevue.com |
