basic setup after vanilla install

---

vi /root/.profile

change the path for the pkgsrc repo to:

ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/i386/5.0/All/
pkg_add lynx
pkg_add pico
pkg_add screen

---

vi /etc/ifconfig.fxp0

192.168.0.20{1,2} netmask 255.255.255.0 

---

vi /etc/sysctl.conf

net.inet.ip.forwarding=1

---

vi /etc/resolv.conf

nameserver 64.59.184.13

---

vi /etc/rc.conf

hostname=chaosvpn{1,2}.440bx.net
defaultroute=192.168.0.1
sshd=yes

---

useradd -m -G wheel chaosvpn_user
passwd chaosvpn_user

---

---

prep to recompile the kernel

make directories

# mkdir /usr/src
# chown chaosvpn_user /usr/src

get the actual source

$ ftp -i ftp://ftp.NetBSD.org/pub/NetBSD/NetBSD-5.2/source/sets/
  mget *.tgz

extract

$ for i in *.tgz
  do
  tar -xzf $i 
  done

after you realize youve extracted to the wrong dir

$ mv /usr/src/usr/src/* /usr/src

copy config stuff

$ cd /usr/src/sys/arch/i386
$ cp GENERIC i686_CVPN_x300


vi i686_CVPN_x30

CFLAGS:
  CPUFLAGS="-march=pentium3m -mtune=pentium3m"

Uncommented:
  PERFCTRS #since this is going to be non-smp kernel (may or may not ever use this)
  GATEWAY
  IPSEC
  IPSEC_ESP
  IPSEC_NAT_T


Might dig more into "tuning" later.

Time to start building the new kernel

$ config ./i686_CVPN_x300
$ cd ../compile/i686_CVPN_x300
$ make depend && make

And install

$ su -
# cp /netbsd /netbsd.orig
# cp netbsd /
