Hello, I am in the process of installing a LAMP System with FC6 as per the 'Howto' at http://howtoforge.org/installing_a_lamp_system_with_fedora_core_6. Everything was going well until I got to the section marked "6 Install Some Software" at http://howtoforge.org/installing_a_lamp_system_with_fedora_core_6_p3. Having entered the below command : - Code: [I]yum install fetchmail wget bzip2 unzip zip nmap openssl lynx fileutils ncftp[/I] I get the error message as shown below : - Code: [I]ileutils ncftp Loading "installonlyn" plugin Setting up Install Process Setting up repositories Could not retreive mirrorlist http://mirrors.fedoraproject.org/mirrorlist?repo=core-6&arch=i386 error was [Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution'). Error; Cannot find a valid baseurl for repo: core[/I] I think the problem is that I have no internet connection. My network is set up as follows : - I connect to the Internet via Cable Modem. This Cable Modem feeds into a SmoothWall Box which has 3x NICs : - NIC 1 = Red (accepts connection from the Internet - IP Address assigned via DHCP from ISP). NIC 2 = Orange (Is the DMZ and feeds into the Server - Static IP Address 10.10.0.1). NIC 3 = Green(Feeds a Wireless Router which in turn feeds the LAN IP Address IP Address 10.10.0.20 - assigned via DHCP). The addreses on the LAN are all assigned via a DHCP running on the Wireless Router and are on a different subnet. I used to have a working Apache Web Server using this set up before. Can anyone tell me what went wrong ? All I did was remove the HDD and place a new one in the machine for this exercise. I have also used the folloing settings for the server. IP Address = 10.10.0.10 Subnet = 255.255.255.0 Gateway = 10.10.0.1 (the IP address for the Orange NIC in the SmoothWall Box) Broadcast = 10.10.0.255 Primary DNS = 18.104.22.168 Secondary DNS = 22.214.171.124 The DNS Servers are those belonging to my ISP. The Server is connected to the Orange interface of the Smoothwall box via a 'Cross-over' cable.
