Squeeze Box Receiver (SBR) configuration using Net-UDAP
Howto configure a sqeezebox receiver (SBR) on CentOS
The overall aim is to configure the squeezebox receiver to use it's wired ethernet port.
Residual: This procedure wasn't entirely reproducible. Getting the udap_shell.pl script to reliably detect the SBR didn't always happen.
Download, compile and install Net-UDAP
$ wget 'http://projects.robinbowes.com/Net-UDAP/trac/changeset/129/tags/RELEASE_1.1.0?old_path=%2F&format=zip' $ mv 'RELEASE_1.1.0?old_path=%2F&format=zip' Net-UDAP-1.1.0.zip
Note: To extract the zip archive the 'unzip' package must be installed.
The following prerequisites must be installed
# rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm # yum install make perl-version perl-Perl-Critic perl-Test-Perl-Critic perl-IO-Interface unzip
As per the README instructions:
unzip Net-UDAP-1.1.0.zip cd tags/RELEASE_1.1.0/src/Net-UDAP/ perl Makefile.PL make make test make install
Note: The perl module doesn't compile/test without errors. However, ignoring those errors, it is possible to run the software.
Firewall
The machine running the UDAP perl script must be able to send and receive udp port 17784. Add a firewall rules to allow this traffic
-A udpOut -p udp -m udp --dport 17784 -m state --state NEW -j ACCEPT -A udpIn -p udp -m udp --dport 17784 -m state --state NEW -j ACCEPT
Configuration
As per the instructions, press the button on the front of the squeezebox receiver (SBR) for 3 seconds (when it should flash red), so the SBR is in 'init mode'.
Run the perl script 'udap_shell.pl' (Note: The scripts extracted above are not executable, so explicitly run perl).
$ perl udap_shell.pl
Look at the sample usages of Net-UDAP. For this setup I wanted a wired DHCP configuration. The configuration commands used are:
discover conf 1 set interface=1 lan_ip_mode=1 save_data reset

Default Configuration
The configuration of the squeezebox receiver (SBR) prior to configuration is shown below. The setting of interface=0 disables the wired LAN interface.

Net-UDAP crash
When running the udap_shell.pl script they following error occurs. The workaround appears to be to restart the script.
