I am getting a network failure on a fresh RHEL 4 install.

logged in as root, so installer can use 'ifconfig' and 'chkconfig'

log is as follows:

2005-12-07 16:21:47,479 ERROR Operation failed: Network check failed -- Could not find a host name in DNS that matches an IP address
2005-12-07 16:21:47,479 ERROR Operation failed: Network check failed -- IP address associated with host name 'mybox.mynetwork.com' is '127.0.0.1'

I am wondering if this has something to do with the /etc/hosts file? I have had similar issues before, with other products, on other test installs.

on some of my other platforms, the 'loopback' entry in /etc/hosts is:
127.0.0.1 localhost.localdomain localhost myboxname

On the RHEL and Fedora installs I have done, it reads:
127.0.0.1 mybox.mynetwork.com myboxname localhost.localdomain localhost

I have had issues with mysqld and similar, because of this. My local DNS server (internal, for my network) has an entry for this machine. If I dig mybox.mynetwork.com it returns the correct local ip assigned to this machine.

I dont understand. (I am kind of new at this)

Hi Wolf,

Yes, that is an annoying gotcha that happens in RHEL 3 and 4. Modify your /etc/hosts file to read

127.0.0.1 localhost.localdomain localhost
xxx.xxx.xxx.xxx mybox.mynetwork.com mybox

with the xxx's being the ip address for mybox.
