Clement is an email server application. Its main function is to block unwanted mail (spam) as soon as possible in the email exchange process. It accepts or rejects email while the SMTP session, initiated by the email sender, is still pending, accepting legitimate email messages without the need to return an error status to non-existent or "borrowed" return address later. Clement can operate in two modes, either as a standard MTA (as sendmail, Postfix, Exim, Exchange, etc.) to store email in the recipient's own area, or to transmit the mail to an another SMTP server acting as smart spam filtering device. Each email domain name Clement knows about can be treated in one of these two modes depending on the group to which the domain name has been set. Each message is verified by a virus scanner (ClamAV) while the SMTP connection is still open, but the refusal of mail and the reason for refusal is notified to the actual sender. Mail management is done via a Web interface and can be delegated to three administrative levels (Root-Admin, Group-Admin, Domain-Admin). Standard users can access their own logs (sent email status, email rejected, quarantined email, etc.). With this interface, the user can handle the rejection and acceptance of mail. Users who are level "Admin" can access the session logs (via the Web interface). Clement uses a SQL database (PostgreSQL, MySQL) to store and manage logs, user profiles, and dynamic management of directives concerning the sender-receiver relationship.
skd is a tool for the simple distribution of SSH keys in a growing environment. It allow you to create hosts, group them, and link that group a group of users with keys to easily distribute all affected keys. skd generates a DSA or RSA keypair, which is saved to its database and used as the authentication source for skd itself. This keypair can (and should be) additionally be encrypted using a passphrase. This allows you to simply add a user with their key and press one button to grant (and revoke!) the user's access to all needed hosts.
nnmon is a central database and a Web interface for the nmon program's data. It allows you to store and view nmon data instantly. nnmon_sender.pl is a pure Perl script. It runs the external nmon program and opens its output file for reading. Every line read from the file is sent to the nnmon_server.py program via TCP/IP socket. nnmon_server.py reads incoming data, parses it, and inserts the result to the database. nnmonweb is a PHP script that lets you view monitored systems in a tree. If there is data for a system for the last 12 hours, it will show a chart on the right hand side. The database and server components have been tested on RHEL 5.5. The client parts have also been tested on AIX 6.1 and RHEL 5.5.
