Network Inventory Lookup Assistant (NILA) is a combination network inventory database and lookup tool. It is designed to be compact and easily extensible to provide a custom solution for your network. The backend is a Perl CGI script which processes requests and returns output. It uses a SQL server for its storage and retrieval. The frontend is a Perl script which queries the HTTP backend and returns results. It is intended to be simple enough that you can take full advantage of its querying and updating abilities from a console or shell script.
ssh-ident allows you to have a single line in your .bashrc, then let it take care of loading ssh-agents when first needed, load all the necessary keys, and share ssh-agents across login consoles. If you have multiple identities for the same account, it is able to load different keys depending on the host you connect to or the path you are working from. At the same time, it keeps the ssh-agents separated and forwards only the keys which are needed for the specific host. It also allows you to specify ssh-add options, so you can automatically lock keys which are unused for a certain time, or have a confirmation request every time a specific key is used.
