DHCP_HOSTNAME in ifcfg-eth0
Hello Is there a way for the dhcp client to send the current host name of the machine when requesting a lease ? Currently I have to include a line like DHCP_HOSTNAME=appserver2 in my /etc/sysconfig/network-scripts/ifcfg-eth0, but I would like to tell the dhcp client to just 'also send the hostname' and then the client to get the current hostname itself, instead of having the name hard-coded in the ifcfg-eth0 file. I am trying to get my router to kn...

dhclient.conf being ignored!
It seems that the prominent North American Enterprise Linux vendor has decided that dhclient.conf should be ignored, i.e. ifup-eth causes dhclient to be called with "-cf /etc/dhclient-$(DEVICE).conf", and then ifup-eth/ifdown-eth wipes the file out each time. Through the use of "DHCP_HOSTNAME" in ifcfg-eth0 you can specify a host name, but because of the above behavior of ifup-eth other options don't seem to be able to be passed to dhclient. I tried placing supersede ntp-servers into dhclient-up-hooks, but that also seems to be ignored, and my google fu seems to be failing on...

Server w/ DHCP address incorrectly registers with WINS
I am sneaking Linux and Samba into my client's IT department (with the cooperation of the IT manager) and we have a few issues getting the system talking to the rest of the network. The network we are inserting the system into uses WINS and does not have DNS for local hostname resolution. The system is required to get its IP address via DHCP. The system is running a vanilla install of

CentOS 5.2 -- how do I choose a wireless network?

resolv.conf rewritten every reboot. How to figure out who and why?
My machine has a static IP, with dhcp and IPv6 disabled. Every time I reboot, some process rewrites /etc/resolv.conf, including a comment about dhcpclient. The only package I have installed that shows up in "rpm -qa|grep -i dhcp" is dhcpv6-client-1.0.10-16.el5, and nothing in there is named dhcpclient. I'd like to figure out what software is rewriting this file and why. man 5
