Networking in Solaris 10

Since *BSD is getting boring, I decided to try an old but largely used enterprise OS: Solaris 10. I’m trying the latest update so it’s got ZFS and all the bling.

Anyway, I’m posting this so I can find this again whenever I need to.

Hostname/DNS

Here be hostname: /etc/nodename. Don’t forget to add relevant entries to /etc/hosts. And while at it, don’t forget to add loghost to 127.0.0.1 on hosts entry. Don’t forget to set /etc/nsswitch.conf with content of /etc/nsswitch.dns since unless you know what you’re doing, that’s what you want.

Static IPv4

/etc/hostname.if. Fill in with relevant IP address.

Static IPv4 Default Route

/etc/defaultrouter. Fill in with relevant default gateway’s IP address

Static IPv6

/etc/hostname6.if. Fill in with IPv6 address in following format:

addif some:ipv6:add::ress/prefixlen up

Also disable service for network discovery protocol (IPv6 routing etc autoconfiguration) by issuing

/usr/sbin/svcadm disable routing/ndp

Or not. It’s an undead zombie. Just add that line to /etc/rc3.d/S99rclocal (or create the file and make it executable if it isn’t there yet) to really kill the service upon boot.

Static IPv6 Default Route

It’s buried in /etc/inet/static_routes. Modified using route -p. Execute this for setting default IPv6 route:

route -p add -inet6 default de:fa:ult::gw

And that’s about it. It’s more or less same in Solaris 11 but you need to disable physical:nwam service in there. Also there’s ipadm but I think it’s still pretty much a black magic.

DHCP

For DHCP/dynamic, it is much easier:

touch /etc/hostname.if
touch /etc/hostname6.if
touch /etc/dhcp.if
