2.3. usefull programs

/volume1/@appstore/DNSServer/bin/nsupdate

2.4. startup script

/volume1/@appstore/DNSServer/script/reload.sh

3. DHCP server

The build-in DHCP server is based on dnsmasq. Nothing wrong with dnsmasq, but it could not do what i want:

disable all unknown macaddresses and allow only the ones i have defined in a so called whitelist.

3.1. disable dnsmasq

cp /etc/rc.network /etc/rc.network-org
sed -i s~"dnsmasq --user=root"~"dnsmasq --version --user=root"~ /etc/rc.network

3.2. install package

ipkg install dhcp

3.3. config files

8. rexx

Download from http://rpmfind.net/linux/rpm2html/search.php?query=ooRexx

or following link

tar xzPvf rexx.armv7h1.tgz -C /
mkdir /volume1/bin
touch /volume1/bin/rexx
chmod +x /volume1/bin/rexx
ln -s /volume1/bin/rexx /usr/bin/
vi /volume1/bin/rexx

#!/bin/sh
export PATH=$PATH:/opt/rexx/
export LD_LIBRARY_PATH=/opt/rexx/
/opt/rexx/rexx $@

since the DSM upgrade to version 6 on 27/03/2016, the rexx output was messed up:

root@nas010:~# rexx

/opt/rexx/rexx: /lib/libstdc++.so.6: no version information available (required by /opt/rexx/librexx.so.4)

/opt/rexx/rexx: /lib/libstdc++.so.6: no version information available (required by /opt/rexx/librexxapi.so.4)

Syntax is "rexx filename [arguments]"
or        "rexx -e program_string [arguments]"
or        "rexx -v".

Copy following libstdc.so.6 to /opt/rexx/
