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?
