The Cornfed SIP User Agent is a Session Initiation Protocol (SIP)-based Softphone for x86 Linux systems running the GNOME Desktop environment. It allows you to make Internet phone calls using an Advanced Linux Sound Architecture (ALSA) or Open Sound System (OSS) sound card with speakers and microphone as your telephone handset.
SSID-based SMTP server changer for Evolution is a simple script that uses gconf and NetworkManager (via D-Bus) to check which wireless network (SSID) you are currently connected to, and updates Evolution's accounts list (in gconf) to point to the correct SMTP server for that network. It is useful for when roaming between wireless networks that are connected to different ISPs.
Pidgin-paranoia is a plugin for Pidgin (formerly known as Gaim) that provides information-theoretically secure encrypted conversations using one-time pads. Because the plugin uses a one-time pad where the secret key has the same length as the message and the key is only used once, the encryption is information-theoretically secure. This means that from the encrypted messages the contents of the messages are not revealed. In short: If you use truly random numbers to generate the key files, and if you keep them perfectly secret, one-time pads can not be broken.
gSTM, the Gnome SSH Tunnel Manager, is a front-end for managing SSH-tunneled port redirects. It stores tunnel configurations in a simple XML format. The tunnels, with local and remote port redirections, can be created, deleted, modified, and individually started and stopped through one simple interface. It is useful for anyone wanting to securely access private services over an encrypted tunnel.
