If you want open source tools, scripts and utilities for your Cisco gear, COSI is the place to go. Tools can be downloaded for free but COSI warns that none of the widgets are supported by Cisco's Technical Assistance Center (TAC), so don't go running to them if you have questions about the open source tools. Among the available tools include ACL_maker.pl, a Perl Script that lets you manipulate Cisco access control lists and Ciscocmd, a Tcl/Expect script that you can use to send a set of commands to a large number of IOS target hosts and get a separated report for each node. The site also provides a link to the
