Refer to section 3 of the Yuma User Manual for a complete introduction to Yuma.
This section focuses on the client and server tools within the Yuma programs.
This document is intended for users of the Yuma NETCONF client and server programs. It covers the installation of the Yuma packages.
The following requirements must be met for Yuma to be installed.
The following platforms are supported at this time for the Yuma binary package:
•Ubuntu version 9.10 (32 bit x86 and 64-bit AMD)
•Fedora version 12 (32 bit x86)
The following programs and libraries need to be available for Yuma to work.
The libxml2 package is needed by the yuma package for some of the XML parsing functions. This package is installed by the default Linux installation process.
To build yuma sources, also install the developer version of this package. It is called libxml2-dev on Ubuntu systems.
The libssh2 package is needed by the yuma package for the yangcli program to connect to NETCONF servers using the SSH protocol. This package is called libssh2-1 on Ubuntu platforms. This package is not installed by the default Linux installation process.
To build yuma sources, also install the developer version of this package. It is called libssh2-1-dev on Ubuntu systems.
The ncurses library is needed by the yuma package for some terminal support. This package is installed by the default Linux installation process.
It is called libncurses5 on Ubuntu systems.
To build yuma sources, also install the developer version of this package. It is called libncurses5-dev on Ubuntu systems.
The zlib library is needed by the yuma package for some compression support, used by other libraries that yuma imports. This package is installed by the default Linux installation process.
To build yuma sources, also install the developer version of this package. It is called libz-dev on Ubuntu systems.
The yuma files are split into 3 packages, described below.
The yuma package contains all the shared libraries, binary programs, man files, YANG files, sample .conf files, needed to run all the programs. It must be installed.
The yuma-doc package contains all the documentation files, including this file. It is only needed if you want the PDF and HTML versions of the documentation installed. Since these files take up a lot of disk space, an optional package is used to install them.
The yuma-dev package contains all the server instrumentation library (SIL) developer files. It is only needed if you want to add YANG modules to the server, and develop your own server instrumentation library code to load into the netconfd server at run-time.
This section describes how to use the platform package manager program to install the Yuma programs.
First, make sure the external libraries are installed.
mydir> dpkg --list libxml2 libssh2-1
If the library is installed, the status will show 'ii libxml2', as in the example below:
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Description
+++-==============-==============-============================================
ii libssh2-1 1.2.2-1 SSH2 client-side library
ii libxml2 2.7.6.dfsg-1ub GNOME XML library
mydir>
If the libxml2 library is not installed, then install it with following command:
mydir> sudo apt-get install libxml2 libssh2-1
Next, install the Yuma package. Here is an example showing all 3 packages being installed.
The actual hardware platform identifier may be different:
mydir> sudo dpkg -i yuma-2.1-1.u1004.i386.deb
mydir> sudo dpkg -i yuma-doc-2.1-1.u1004.i386.deb
mydir> sudo dpkg -i yuma-dev-12.1-1.u1004.i386.deb
First, make sure the external libraries are installed.
mydir> rpm -q libxml2 ncurses libssh2
If the packages are installed then a line will be printed for each package showing the version, such as in the following example (your versions may be different)
libxml2-2.7.6-2.fc14.i686
ncurses-5.7-3.20090207.fc14.i686
libssh2-2.3.8.fc14.i686
If a package is not already installed, then install it. This example shows how to install both external libraries:
mydir> sudo yum install libxml2 ncurses libssh2
Next, install the Yuma package. Here is an example.
The actual yuma revision and hardware platform may be different:
mydir> sudo yum localinstall yuma-2.1-1.fc14.i686.rpm

The unix 'man' program can be used to get documentation about each program. For example:
•man yangcli
•man yangdump
•man yangdiff
•man netconfd
•man netconf-subsystem
•man make_sil_dir
Each program also has extensive help information available with the --help CLI parameter. For example:
•yangcli --help
•yangdump --help
•yangdiff --help
•netconfd --help
If you are just using the Yuma client applications, then there is no further mandatory setup required.
•If a work directory is used, then the $YUMA_HOME environment variable needs to be defined. Refer to the user manual for details.
•If Yuma is installed in a location other than the default location described above, then the $YUMA_INSTALL environment variable needs to be defined. Refer to the user manual for details.
•The following binary applications are available:
◦/usr/bin/yangcli: NETCONF-over-SSH client application
◦/usr/bin/yangdump: YANG compiler
◦/usr/bin/yangdiff: YANG compare program
◦/usr/bin/make_sil_dir: Bash script to create a new SIL work directory. Refer to the Yuma Developer Manual for details.
The Yuma server does not automatically start running when installed. This will be supported in a future release.
The following steps must be taken to start the netconfd server:
•You must modify the /etc/ssh/sshd_config file, and add the 'netconf' subsystem, as described in the user manual.If the yuma package was installed in a non-default location, then the path to the netconf-subsystem will be different than the example below. The following commands must be present:
•
Port 22
Port 830
Subsystem netconf /usr/sbin/netconf-subsystem
•Start the netconfd server, as described in the user manual or quickstart guide. This can be in the foreground or the background. If it is in the background, then the '--log' CLI parameter should be provided, as shown below:
mydir> /usr/sbin/netconfd --log=$HOME/mylog &
•Restart the SSH server. This is a platform-specific task. Refer to the sshd manual page for your system for more details. This step may need to be run as root or with the 'sudo' program.
