Firstly, try asking on comp.os.linux.development.apps. We're a
friendly bunch :-)

Secondly, for basic networking you don't need anything more
sopisticated than the C Standard Library (GNU libc), which includes
the POSIX/Single UNIX networking system calls. See
<URL:http://www.unix.org/version3/online.html> for more details. Have
a look at connect(), socket() etc. in the "System Interfaces" section.

This quick search shows some of the C++ networking libraries in
Debian:

$ apt-cache search net | grep -i "C++"
[irrelevent packages snipped]
libace-dev - An Object-Oriented Network Programming Toolkit in C++
libace5.3.1 - An Object-Oriented Network Programming Toolkit in C++
libcapsinetwork-dev - C++ network server library, development files
libcapsinetwork0 - C++ network server library
libccrtp-dev - Common C++ class framework for RTP packets
libccrtp1-1.0-0c102 - Common C++ class framework for RTP packets
libcommoncpp2-1.0-0c102 - A GNU package for creating portable C++ programs
libcommoncpp2-dev - Header files and static libraries for Common C++ "2"
libicq2000 - An ICQ2000/2001 C++ library
libicq2000-dev - An ICQ2000/2001 C++ library - development files
libicq2000-doc - An ICQ2000/2001 C++ library - documentation
libpbd0 - Library of useful, generic C++ objects
libwvstreams3 - C++ network libraries for rapid application development
libwvstreams3-base - C++ network libraries for rapid application development
libyehia0.5-0 - Yehia - A C++ application framework - runtime
libyehia0.5-dev - Yehia - A C++ application framework - development

Lastly, as others have already mentioned, the source for all of the
networking tools is available (with certain restrictions--read the
licences carefully!). You'll learn a lot by reading code. Start by
looking at the "iputils" source package (ping etc.).
