Installing NO-IP on your FOX board

Get your FOX board a host and domain name via no-ip dyndns service.

Approach your FOX board from all over the world, via world wide web ...
Dyndns is a good solution, your current foxBoard IP address is monitored by a daemon who forwards it to a dyndns server, which updates the dns-server.

A lot of these services are for free !
One of these free services is http://www.no-ip.com.
Register at their website and add a host.

On your Virtual Terminal

Install the Axis SDK on your Linux box and go to the /home/fox/devboard-R_01 directory and type:

# . init_env
  Prepending "/..../devboard-R2_01/tools/build/bin" to PATH.
  Prepending "/usr/local/cris/bin" to PATH.
# cd apps

Install no-ip client software: http://www.no-ip.com/downloads.php?page=linux

# wget http://www.no-ip.com/client/linux/noip-duc-linux.tar.gz
# tar xzvf noip-duc-linux.tar.gz
# cd noip-2.1.7

Do NOT use the Makefile from noip ...
Edit a new file and save it with the name makefile:

AXIS_USABLE_LIBS = UCLIBC GLIBC
include $(AXIS_TOP_DIR)/tools/build/Rules.axis

PROGS = noip2

all: $(PROGS)
$(PROGS): $(PROGS).o
	$(CC) $(LDFLAGS) $^ $(LDLIBS) -o $@

clean:
	rm -f $(PROGS) *.o core

If your program will run on a FOX with glibc library (delivered by default with the FOX with Kernel 2.4.x) type:

# make cris-axis-linux-gnu
  make[1]: Entering directory `/home/devboard-R2_01/apps/noip-2.1.7'
  make[1]: Leaving directory `/home/devboard-R2_01/apps/noip-2.1.7'

Inside the directory noip-2.1.7 will be created a hidden file .target-makefrag that has instructions for the make process on which general library and environment to consider during the compilation phase.

# make

Now to run this program you have to transfer it on the FOX board. The easiest way is to use SCP:

# scp noip2 root@192.168.1.90:/mnt/flash

On your FOX Board

Open a putty session and login

go to the directory /mnt/flash

# cd /mnt/flash

and launch your No-IP program on the FOX board:

# ./noip2 -C -c /tmp/no-ip2.conf

The installation wizard is started, and a conf file is created:

Auto configuration for Linux client of no-ip.com.
Please enter the login/email string for no-ip.com: xxxxxxx
Please enter the password for user 'xxxxxxx' ********
Only one host [inktvis75.no-ip.org] is registered to this account.
It will be used.
Please enter an update interval:[30]
Do you wish to run something at successful update?[N] (y/N) N
New configuration file "/tmp/no-ip.conf" created.

Move the config file:

# cd tmp
# mv no-ip2.conf /etc/
# cd ..

Start the daemon:

# ./noip2 -c /etc/no-ip2.conf

Enable the same port in your router, modem, as you defined in /mnt/flash/etc/httpd.conf.

/mnt/flash/etc/httpd.conf

...
server.port = 80
...

Auto system startup/shutdown

You can create a start/stop script

/etc/init.d/noip

#!/bin/sh
# Description: Start / Stop No-IP service

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
NAME="No-IP"
DESC="DNS Services"

case "$1" in
  start)
    echo "Starting $DESC: $NAME."
    /mnt/flash/noip2 -c /etc/no-ip2.conf
    /mnt/flash/noip2 -S -c /etc/no-ip2.conf
    echo " "
  ;;
  stop)
    echo -n "Stopping $DESC: $NAME"
    killall noip2
    echo "."
  ;;
  restart)
    $0 stop
    $0 start
  ;;
  show)
    /mnt/flash/noip2 -S -c /etc/no-ip2.conf 
  ;;
  *)
    N=/etc/init.d/$NAME
    echo "Usage: $N {start|stop|restart|show}" >&2
    exit 2
  ;;
esac

exit 0

Run at Startup

And run the following to have it startup and stop on system start/shutdown.
Give noip its access rights. Then make a symbolic link to stop the service when the FOX board is shutting down.

# cd /etc/init.d
# chmod 0700 /etc/init.d/noip
# chown root:root /etc/init.d/noip
# ln -s /etc/init.d/noip S97noip
# ln -s /etc/init.d/noip K04noip

The scripts in the directory /etc/init.d/ starting with S[number] are automatically run during system startup with parameter start.
The number defines the order the scripts are run.
Likewise, scripts starting with K[number] are run when the system is shutting down with parameter stop.
