ncdc

ncdc is an open source, free distributed, lightweight and modern Direct Connect (DC) client for your Linux terminal, providing a user-friendly command-line interface (CLI) powered by the well known NCurses libraries.

Supports NMDC and ADC protocols

Key features include IPv6 support, support for connecting on multiple hubs at the same time, support for both NMDC and ADC protocols, private messaging and chatting, file uploading and share management, download queue management, as well as file list browsing.

Additionally, we can mention TTH-checked file downloading, file searching, bandwidth throttling, support for browsing the user list of the currently connected hub, and support for adcs:// and nmdcs:// secure connections.

Offers support for encrypted UDP messages

The application also features different connection settings for each hub, encrypted UDP messages (ADC SUDP), subdirectory refreshing, nick highlighting and notification in chat windows, trust on first use for TLS-enabled hubs, and efficient file uploads using sendfile().

Among other interesting features, we can mention support for a single listen port for both TCP and TLS connections, connection management capabilities, support for opening large file lists in a background thread, and low memory usage.

Doesn’t support SOCKS proxy, NAT traversal or OP features

On the other hand, the ncdc application cannot be used to run OP commands like file list scanning or client detection, cannot be used for NAT (Network Address Translation) traversal, and doesn’t support SOCKS proxy.

The software can be easily installed on any distribution of GNU/Linux where the NCurses libraries are available, including Arch Linux, Fedora, openSUSE, Frugalware and Gentoo, which are officially supported.

The FreeBSD and Mac OS X UNIX-like operating systems are also supported. At the moment, the application can be successfully installed on computers supporting either of the 32-bit or 64-bit CPU architectures. Detailed installation instructions are provided on the project’s website.
