Networking

You can run 'dhclient em0' to get networking up.

adding basic packages

There's a lot of stuff that won't work on 4.2 without installing 'Xbase' (the X11 base set).

This can be done like so:

 dhclient em0
 cd /
 lynx -dump ftp://ftp.openbsd.org/pub/OpenBSD/4.2/i386/xbase42.tgz > xbase42.tgz
 tar xzvphf xbase42.tgz
 ldconfig -m /usr/X11R6/lib # (or reboot)
 

Now you can add basic packages. Like so:

 
 export PKG_PATH=ftp://ftp.openbsd.org/pub/OpenBSD/4.2/packages/i386/
 pkg_add -v bash
 pkg_add -v nano
 

You can replace 'ftp.openbsd.org' with an appropriate mirror that is closer to you if you wish. A list of mirrors is at http://www.openbsd.org/ftp.html#ftp

For more info on xbase/expat, please see http://www.linuxquestions.org/questions/bsd-17/installing-x-in-openbsd-617200/ for more info (basically, a lot packages need gettext, which uses expat, which is only in xbase42.tgz)
