FreeBSD DHCP Set Hostname ( Empty Hostname After Reboot )

Posted on in Categories , , , , last updated July 16, 2009

I’m using FreeBSD 7.2 on HP laptop and getting IP info via WI-FI router. I’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?

Ubuntu Linux Static IP Configuration

Posted on in Categories , , last updated July 5, 2016

I have an Intel Corporation 80003ES2 LAN Gigabit Ethernet Controller. How do I set a static IP address settings for my Ubuntu Linux server as follows:
DEVICE name : eth0
Type: static
IP ADDRESS : 10.10.29.66
NETMASK : 255.255.255.192
ROUTER IP: 10.10.29.65
Broadcast: 10.10.29.127

How do I setup a static IP address under a Ubuntu Linux 14.04 or 16.04 LTS server?
