GNet Library

GNet is a simple network library. It is written in C, object-oriented, and built upon GLib. It is intended to be easy to use and port. GNet comes with documentation and examples. It is licensed under the GNU Library General Public License (LGPL).


GNet is not developed any further. You should not use it in new software.

GNet should be considered deprecated and has been replaced by the newly-added platform-independent network and socket abstraction layer in GLib/Gio (with the release of GLib 2.22), ie. Lowlevel platform-independent network support, DNS resolution, and Highlevel network functionality.

The latest release is GNet 2.0.8 (February 12, 2008)


  • fully asynchronous
  • TCP "client" and "server" sockets
  • UDP and IP Multicast sockets
  • High-level TCP connection and server objects
  • Asynchronous socket IO
  • Internet address abstraction
  • Asynchronous DNS lookup
  • IPv4 and IPv6 support
  • Byte packing and unpacking
  • URI parsing
  • SHA and MD5 hashes
  • Base64 encoding and decoding
  • SOCKS support
  • basic HTTP client
  • has been ported to Linux, *BSD, MacOSX, Solaris, HP, and Windows. It may work on other flavors of Unix too.


GNet requires GLib 2.0 (there are old versions for glib-1.2, but those are ancient history). You can get GLib from the Gtk+ website or, if you have a system with packages (eg, Red Hat or Debian), look for the latest GLib package: it is usually called glib2-devel or libglib2.0-dev.


The latest release source tarballs can be found on the GNOME ftp server, the latest development snapshot can be obtained through the git repository:  git clone git:// 

Many Linux distributions (e.g. Debian) ship ready-made binary GNet packages. You can obtain them from your distro of choice. No up-to-date packages are available for Windows or Mac OS X (not from the GNet maintainers at least).
