Iâ€™m using FreeBSD 7.2 on HP laptop and getting IP info via WI-FI router. Iâ€™ve setup hostname in /etc/rc.conf buy after the boot process, I check host name with “hostname” command, but get empty line. Setting hostname with “hostname” works well, but after reboot host name is still empty. I suspect it has something to do with DHCP settings. How do I set hostname-using DHCP?
How do I change or set my hostname ( computer name ) under OpenBSD operating system?
Q. Under Windows Server 2003 I can use active directory domain tools to get information about current domain and hostname. Can you tell me command to list current domain name and hostname under Red hat enterprise Linux 5?

a) hostname – show or set the systemâ€™s host name
b) domainname – show or set the systemâ€™s NIS/YP domain name
c) dnsdomainname – show the systemâ€™s DNS domain name
d) nisdomainname – show or set systemâ€™s NIS/YP domain name
e) ypdomainname – show or set the systemâ€™s NIS/YP domain name

The domain name is also used by NIS/YP or Internet DNS:
