I have both wired and wireless network interfaces configured:
box0 log # rc-update show|egrep 'enp3s0|wlp2s0'
net.enp3s0 | default
net.wlp2s0 | default
(1). Is there a way to instruct the system as to which network interface
to use, so it doesn't try to bring up the one not intended to be used at
boot time:
box0 log # egrep 'enp3s0|wlp2s0' messages

(2). sshd seems to start only if the wired interface is up. How do I
tell it start when the wireless interface is running?

Thanks.

Yes, use a network manager like Wicd. Wicd has an option to use the wired
interface if a cable is connected, falling back to wireless otherwise.

It seems to me that your problem is that you’re not always connected
with both interfaces at the same time. In the default configuration,
network-dependent services only start if all network services are up
and running. This is most annyoing for laptop users who might not be
connected at all at times.
The solution is to not have network services depend on all interfaces.
Please look at /etc/rc.conf for rc_depend_strict; if you set it to "NO",
then services are satisfied with any net.* service, even net.lo.
I suppose there is a way to set up something more fine-tuned in
/etc/conf.d/net, but that must be explained by someone else as I
lack that knowledge. ;)

Thanks for your input. I am running gentoo on a laptop, as you have
rightly guessed. It was suggested to me by somebody else on this list
that using Wicd might be a viable option.

Yeh, same advice here, try wicd first. If you don't want a GUI (or you
don't have corresponding UI toolkits installed), there's also the option
to configure and use wicd via the ncurses interface.

Just thought I'd give the other popular alternative of the Redhat backed NetworkManager.
Also, if you don't wait for the interface to come up I don't think the service can bind to the interface (and it obviously can't bind to an IP). Probably not an issue for ssh but possibly one for MySQL or Apache.
