This document gives an introduction on how to install and test the Open Source version of NMM for Linux.
In this document, we assume that NMM package is called nmm-1.0.0.tar.gz and will be extracted to directory /home/bob/nmm-1.0.0 . Please replace these names as appropriate, e.g. with the name of the NMM package that you are actually using.
You need a properly configured operating system, e.g. a Linux on a PC or some other platform. On Linux, most NMM examples and applications require a graphics board with configured Xv extension (refer to the output of xvinfo) and a sound board or chip that can natively playback different sampling rates such as 44.1 kHz. All other hardware, such as cameras, is optional.
To allow one running NMM system to access another running NMM system, the port 22801 and the port range 5000-6000 must not be blocked by a firewall.
Furthermore, access to distributed systems is restricted to systems in your LAN or to systems that are defined as alias, e.g. within /etc/hosts . If for example, your are using a system called host1.domain.com , you have to specify host1 in addition to host1.domain.com in /etc/hosts when using or configuring distributed NMM applications. Numeric IP addresses are currently not supported. In addition, hostnames of systems should also be set according to this rule. For example, use host1 instead of some other name.
In addition to this, all hostnames must be written in lower case letters if they are assigned to an NMM application (e.g. as command line argument or within a clic graph description) even if the corresponding hosts include capital letters within their hostname.
Please note that /etc/hosts must also include the hostname and IP address of your system if no DNS server is available. Furthermore, some Linux distributions include the line 127.0.0.2 host1.domain.com host1 into /etc/hosts . In this case you must replace the numeric IP address 127.0.0.2 with the real IP address of your system.
