Hi,
I have a laptop running Solaris Community Edition (build 90). This has
two network interfaces

wpi0 - wireless

Marvel/yukonx (forget exact name), which has a Gigabit wired ethernet

Is it possible to use these two networks, so I can use the laptop at
home, in a hotel etc on WiFi, but leave a fixed IP (192.168.10.10) so I
can connect to another Sun with a simple crossover cable? (There's no
router or switch, as this has to be used with the bare minimum of
hardware).

I've got the crossover cable working between two Sun with both having a
fixed IP, but can't get the WiFi working like this. I've previously had
the WiFi working fine, but never with 1 Gbit/s ethernet

I need the WiFi to act as a DNS client and be able to connect to the
internet etc, but the ethhernet has no such need.

It seem if /etc/resolv.conf has the names of DNS server, the ethernet
will try to resolve a hostname and spend ages to boot. But clearly the
WiFi needs a DNS server.


I don't care if I run a couple of scripts to set up one or the other -
there is no need for me to have both WiFi and the fixed address at the
same time.


Any ideas?

WIth gigabit Ethernet, you don't need a crossover cable. The interface
is auto-detecting.

What you want to do is proabably doable using nwam (network auto magic).

Thanks, that is useful to know. I did not have a long crossover, and a
normal cable will allow me to keep my distance from the server.

Thanks. I'll persist with that. I dont have my laptop handy at this
moment, but I'd really like to get WiFi wokring again, but I absolutely
need to keep it with a fixed IP.

I guess I can run sys-unconfig ! A bit drastic though

What have you set in /etc/nsswitch.conf?

If you set "hosts" to be "files dns" and then put your ethernet name/IP
information in /etc/hosts, then this should cut out the DNS lookups on
boot.

I've written a script to copy /etc/nsswitch.dns or /etc/nsswitch.file
over /etc/nsswitch.conf. In other words, I'm using the Sun ones supplied
as examples.

I've also either removed /etc/hosts.$wpi0 or /etc/hosts.$gigabit
interface and then touched the other one.
