It turns out that the host doesn't get the address properly when booting with the network installation CD (no, I wasn't going to re-install, I just wanted to test a different DHCP client. Really. I'm not a Windows user, after all), which I think rules out any client config problems.
In other words, there must be a problem with the hardware, the server, or the routing on the network, but what might cause this kind of behaviour? Is there any way a broken network card or similar could give results like this? (I'll try replacing some of the hardware tomorrow, I guess.) Note that I've also tried removing the host's "fixed-address" entry from the server config, so that an IP-address would be assigned from the dynamic pool, but I got exactly the same result when I did. - Toralf _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
