Description of problem: When booting I get the following message: could not look up internet address for dhcppc2. This will prevent GNOME from operating properly. It may be possible to correct the problem by adding dhcppc2 to the file /etc/hosts. Tried the foregoing - did not help Version-Release number of selected component (if applicable): How reproducible: Every bootup Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:

Are you running your own name/dhcp server?
I may be (newbie) but it was what was setup during installation, in other words not intentional.
Setup during installation... of the OS? Of your internet link? How are you connected to the network?
Of the OS. We have (had) a windows network with three nodes. We connect to the internet through a router and cable modem. The other nodes are another desktop machine and a laptop. I would like to completely change over to Linux, however.
192.168.0.1 is your router box?
Router box: 192.168.0.3 Default gateway: 192.168.0.1
OK, it looks like your DHCP server (whatever it is) is handing out hostnames (dhcppc2) that your DNS server (192.168.0.1) can't resolve. The configuration really needs to be fixed on that end.
I'm sorry to 'bug' you, but can you tell me what the configuration should look like. I've spent some time looking into the matter and cannot determine what needs to be done. Thank you, in advance.
Basically, whatever hostnames your DHCP server sends out to the client (dhcppc2) needs to have an entry in the 'home' domain of your DNS server.
FC2 - 2.6.6-1.435.2 Desktop installation. I too have the same error message. As an infant newbie, it would be great if some of these bug reports and other FAQs include an explanation of how these messages are generated. These explanations would go a long way to help develop a diagnostic flow chart. In addition, I didn't see any clarification of the etc/hosts. 1. what is etc/hosts? What actions should I take? 2. as was alluded to above, what are the normal settings? 3. why is the message being generated? 4. what module or process is responisble for creating this warning?
1. /etc/hosts is a networking configuration file that matches host names to IP addresses. Google or some other reference may help more here. 2. A proper /etc/hosts looks something like: ... # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ... The lines starting with '#' are comments. 3. The message is being generated because the hostname that your machine has (dhcppc2, in the above case) does not resolve; the computer can't map that hostname to an IP address. 4. The message comes from early in the startup of the GNOME desktop; it checks this because things do *not* work properly if the machine's host name doesn't resolve. A potential fix, if your hostname is *constant*, is to add it to the end of the 127.0.0.1 line in /etc/hosts.
