LG is a Looking Glass written in Perl as a CGI script. It can execute almost all BGP-related commands and do ping and traceroute in routers or relay these queries to other looking glasses. It supports both IPv4 and IPv6 commands, and is tested with Cisco, Zebra, and Juniper. It can connect to a router using SSH, telnet or rsh.
Release Notes: New TELNET protocol handling for terminal resize was implemented to fit all commands to one line. Async output handling to show traceroute and other commands in realtime was implemented. New configuration options, "Disclaimer" and "SecureMode", were added.
Release Notes: The APNIC whois search page link has been updated. A Junos traceroute problem has been worked around, and a BGP neighbor "ping" link has been added. Libraries are loaded only if needed. All HTML output is valid HTML 4.01 Transitional now.
Release Notes: JunOS IPv6 traceroute was fixed. More parser improvenents were made. The ARIN data source was updated. JPNIC and LACNIC were added.
Release Notes: This release fixes a problem with the timeout LG outputting nothing. The new configuration option "TimeOut" can be used now. Some Juniper output parser enhancements have been added.
Release Notes: It is now possible to add community descriptions. Both ASN and community descriptions can be saved in Berkeley DB format, which reduces load time significantly.
