==== Set up pkgsrc repository ====
+
== Specifications ==
  
Edit the file  '''''/root/.profile'''''<br />
 
  
Change the path for the pkgsrc repo to:<br />

== Equipment Settings ==
ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/i386/5.0/All/
+
== Modifications ==
 +
The firmware has been modified to make extruder 1 (of extruders 0 and 1) behave like extruder 0.  There was a magic smoke event that cooked the current limiting resistor for the extruder 0 heater.
  
The file will be read-only, use ''':wq!'''
+
== Working on it ==
 +
== Known Problems ==
 +
If the hot end stops making itself hot then unplug and plug back in the connectors for the hot end on the x-carriage (the 4 pin connectors to the protoboards)
  
 +
== Future Ideas ==
  
==== Set up network interfaces ====
+
== Firmware ==
  
Edit the file  '''''/etc/ifconfig.fxp0'''''
+
[[File:Einstein-Marlin.zip]]
 
+
This will the the external (wan) interface.
+
 
+
Insert the contents:
+
192.168.0.201 netmask 255.255.255.0
+
 
+
 
+
Edit the file  '''''/etc/ifconfig.fxp1'''''
+
 
+
This will be the internal network (lan) interface.
+
 
+
Insert the contents:
+
10.100.44.1 netmask 255.255.255.0
+
 
+
==== Ensure IP forwarding is set up ====
+
 
+
Edit the file  '''''/etc/sysctl.conf '''''
+
 
+
Insert the contents:
+
 
+
net.inet.ip.forwarding=1
+
 
+
 
+
==== Specify your DNS server ====
+
 
+
 
+
Edit the file  '''''/etc/resolv.conf'''''
+
 
+
Insert the contents:
+
 
+
nameserver 64.59.184.13
+
 
+
 
+
==== Specify basic settings in rc.d to set up networking ====
+
 
+
Edit the file  '''''/etc/rc.conf'''''
+
 
+
Append the following to the end of the file:
+
 
+
hostname=chaosvpn.440bx.net
+
defaultroute=192.168.0.1
+
sshd=yes
+
 
+
 
+
==== Create a new user to do tasks that don't require root ====
+
 
+
# useradd -m -G wheel chaosvpn_user
+
# passwd chaosvpn_user
+
 
+
 
+
==== Continue with the installation of ChaosVPN ====
+
 
+
continue with the steps at:
+
 
+
https://wiki.hamburg.ccc.de/ChaosVPN:NetBSDHowto
+
 
+
 
+
---
+
 
+
===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_x300
+
 
+
<pre>
+
CFLAGS:
+
 
+
  #use whatever is applicable
+
  #see:  http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html
+
  #
+
  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
+
  pseudo-device carp
+
  pseudo-device pf
+
  pseudo-device pflog
+
</pre>
+
 
+
Might dig more into "tuning" later.
+
 
+
Time to start building the new kernel
+
 
+
$ config ./i686_CVPN_x300
+
$ cd ../compile/i686_CVPN_x300
+
$ make clean && make depend && make
+
 
+
And install
+
 
+
$ su
+
# cp /netbsd /netbsd.orig
+
# cp netbsd /
+
 
+
Reboot using the new kernel.
+
 
+
 
+
 
+
===ipfilter setup. routery stuff.===
+
 
+
 
+
 
+
ipfilter is installed by default on Netbsd 5.2 No special packages are required.
+
 
+
---
+
 
+
'''remove this next bit later if testing shows that statically linking in kernel actually works'''<br />
+
Set ipfilter to run by default
+
 
+
vi /etc/rc.conf
+
 
+
ipfilter_enable="YES"
+
#ipfilter_rules="/etc/ipf.rules"
+
ipmon_enable="YES"
+
ipmon_flags="-Ds"
+
gateway_enable="YES"
+
ipnat_enable="YES"
+
ipnat_rules="/etc/ipnat.rules" . create the log file.
+
 
+
 
+
---
+
 
+
 
+
for now, we want ipfilter to log
+
 
+
# touch /var/log/ipfilter.log
+
 
+
vi /etc/syslog.conf
+
 
+
local0.* /var/log/ipfilter.log
+
 
+
---
+
 
+
 
+
vi /etc/ipnat.rules
+
 
+
map fxp1 10.100.0.0/16 -> 0.0.0.0/32 portmap tcp/udp 00000:65000
+
map fxp1 10.100.0.0/16 -> 0.0.0.0/32
+
 
+
 
+
===Misc Non-essential Setup===
+
 
+
 
+
====Optional: Install some convenience packages====
+
 
+
# pkg_add lynx
+
# pkg_add pico
+
# pkg_add screen
+

Specifications

Equipment Settings

Modifications

The firmware has been modified to make extruder 1 (of extruders 0 and 1) behave like extruder 0. There was a magic smoke event that cooked the current limiting resistor for the extruder 0 heater.

Working on it

Known Problems

If the hot end stops making itself hot then unplug and plug back in the connectors for the hot end on the x-carriage (the 4 pin connectors to the protoboards)
