How To - Change Server Name and Network IP Addresses on OpenBSD
Changing the name/IP address of the server is quite simple. Using your favorite text editor editing the following files and change all reference to server name and server IP address.
- /etc/hosts
- /etc/hosts.allow
- /etc/hosts.deny
- /etc/mygate
- /etc/myname
- /etc/hostname.*
- /etc/resolv.conf
- /etc/nttpd.conf
- /var/www/conf/httpd.conf
At the command prompt run the following command to reconfigure your NIC with the new IP address and applicable netmask.
ifconfig le1 inet IP_ADDRESS_HERE netmask NETMASK_HERE
The “le1″ is the device name of the NIC. Not sure what the NIC device name is? At the console prompt type without quotes “ifconfig -a” and locate the network card device name.
