Warning: The project is generally abandoned, it depends on obsolete libraries, Python 2.7 and has been tested only with rather old routers and their software.

ULG version 0.9

• development started in June 2012
• sponsored by CZ.NIC (http://www.nic.cz)
• intention is to create a versatile Looking Glass for various routers
• genshi and cherrypy was used in the beginning
• cherrypy was later dropped and simple CGI was used instead
• the CGI scripts currently do not support mod_python nor mod_wsgi

Basic installation procedure is:

1) install prerequisites: Python 2.6 or 2.7, Genshi, Python CGI module, urllib, pexpect and pygraph and GraphViz 2) install additional router-specific prerequisities:

• JuniperRouterRemoteTelnet: Telnet
• CiscoRouter: OpenSSH client
• BirdRouterRemote: OpenSSH client (default) 3) deploy files in src directory to some place in WWW tree 4) mkdir /etc/ulg; cp config.py.example /etc/ulg/config.py 5) edit config.py to set up routers and credentials 6) edit defaults.py to set up correct paths toward bins 7) create .htaccess file with following contents:

<FilesMatch "(.pyc|.*~)"> Deny from all

Options +ExecCGI AddHandler cgi-script .py

(Or use corresponding config of your web server.)

7) access http://yourserver/path-to-ulg/ulg.py via browser 8) change strings and templates in defaults.py and templates/*.html .

Procedure for Debian Squeeze/Wheezy and Linux Mint 14 (nadia): 1) apt-get install python python-pexpect python-pygraph python-genshi libgv-python whois

All other steps are the same as in generic case.

Future plans:

This "pre-release" is only a preview and "technology demonstrator". Requests and contributions are welcomed. I intend to support BIRD (http://bird.network.cz) and Cisco routers and switches and support typical BGP-related commands and also IGP and L2 management commands in order to make LG more useful for ordinary NOC staff especially for information aquisition during outages and problems.
