Solaris VIP configuration interfaces network routing Configure Network on Solaris Introduction Solaris can be challenging! Especially when you come from a Linux/BSD world and find that all the network commands are strange.
Detecting Network Cards To detect network cards that are present and especially connected, here's a very useful command:
$ dladm show-dev
igb0 link: up speed: 1000 Mbps duplex: full
igb1 link: up speed: 1000 Mbps duplex: full
igb2 link: up speed: 1000 Mbps duplex: full
igb3 link: up speed: 1000 Mbps duplex: full
clprivnet0 link: unknown speed: 0 Mbps duplex: unknown
Or you can use dladm show-links
to get more detailed information about the connection status.
For a link aggregation (IPMP) of type 802.3ad:
> dladm show-aggr -s -i 2 1

Basic Network Configuration Here are some useful commands to reset a Solaris configuration, especially the network:
ifconfig -a Display interfaces with IP and MAC addresses
show-devs Display peripherals
prtconf -vD Display all peripherals
There are two ways to reconfigure the network. The wizard and manual:
sys-unconfig This will reset ALL network configuration! Reboot required
sysidconfig Not tested, but also supposed to reconfigure the network
And then manually, here are the files to modify: /etc/hostname.x (x corresponds to the network interface)
/etc/nodename
/etc/defaultrouter
/etc/netmasks
Dynamic Configuration Finally, a "reboot" or "boot net" should do the trick. However, you may not be able to reboot, so here's the solution:
ifconfig e1000g0 plumb
ifconfig e1000g0 192 .168.0.1 netmask 255 .255.255.0
ifconfig e1000g0 up
ifconfig -a
Persistent Configuration To make it always active:
192 .168.0.1 broadcast + netmask 255 .255.255.0 + up
This is an example.
DHCP How do we set up DHCP? Very simple:
ifconfig e1000g1 dhcp start
To make it permanently active, create a file:
touch /etc/dhcp.e1000g1
touch /etc/hostname.e1000g0
Routing The folks at Sun who can't do things like everyone else have their own route
command. So to list the present routes:
And to add or delete routes:
netstat -rn # show current routes
netstat -rnv # show current routes and their masks
route add destIP gatewayIP
route add destIP -netmask 255 .255.0.0 gatewayIP
route delete destIP gatewayIP
route delete destIP -netmask 255 .255.0.0 gatewayIP
DNS You'll now need to define the nsswitch to add name resolution:
Then edit the resolv.conf file and insert the DNS servers like this:
nameserver 212 .27.40.241
nameserver 212 .27.40.240
Routes Here's how to add routes. To make them persistent, add the -p
option:
route -p add 192 .168.15.0 192 .168.15.1
Persistent routes are stored in /etc/inet/static_routes
.
VIP Here's how to manually set up a VIP in Solaris:
ifconfig <network_interface> addif <vip>/<mask> up
For example:
ifconfig nge1 addif 192 .168.0.1/24 up
