This is how to add a DNS Server to Solaris Box…

First of all, Open up your favourite text editor and add the name servers into /etc/resolv.conf

nameserver 192.168.1.1

If you need to add more, just add another one in the next line…

Following the instructions below will walk you through the process…


bash-3.00# ping www.google.com
ping: unknown host www.google.com
bash-3.00# cat /etc/resolv.conf
nameserver 192.168.1.1
bash-3.00# cd /etc/
bash-3.00# cp -p nsswitch.conf nsswitch.conf.org
bash-3.00# cp -p nsswitch.dns nsswitch.conf
bash-3.00# /etc/init.d/nscd stop; /etc/init.d/nscd start
bash-3.00# ping www.google.com
www.google.com is alive
bash-3.00#

As you can see, the Name Server is working!

How to add IP Address / Default Gateway on Sun Solaris

Adding IP address and default gateway is rather straight forward as long as the interface is loaded. To see whether the interface is loaded, issue the command ifconfig –a

You should see something like the following…


bash-3.00# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
rtls0: flags=1000842<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 0.0.0.0 netmask 0
ether 0:6:4f:47:76:1e

In this case, we will be adding the IP address and subnet mask to rtls0 along with the default gateway.

IP Address: 192.168.1.60
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1

Here is how its done…


bash-3.00# ifconfig rtls0 192.168.1.60 netmask 255.255.255.0 up
bash-3.00# route add default 192.168.1.1
add net default: gateway 192.168.1.1
bash-3.00# ping 4.2.2.2
4.2.2.2 is alive

Success! We can now ping a WAN IP! and here is the new output of ifconfig -a


bash-3.00# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv 4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
rtls0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 192.168.1.60 netmask ffffff00 broadcast 192.168.1.255
ether 0:6:4f:47:76:1e
