BSD sockets

BSD sockets is just about the most common API for programming network applications running on unix systems.

Most CL implentations have some kind of network API, which on Unix systems is usually an interface to the system's BSD socket support.

db-sockets (a slightly hacked version of which is also in SBCL as sb-bsd-sockets) is a fairly low-level socket interface for CMUCL
acl-compat (part of Portable Allegroserve) includes a (partial?) Allegro-compatible socket interface for several Lisp implementations
CLOCC includes a generic socket interface for many Lisp implementations.
kmrcl also has a socket interface covering 3 Lisps.
IOlib has a socket interface that supports at least SBCL, CMUCL and CLISP

It is easiest to get started with CL network programming by sculpting an existing, known-working program. The Apache mod_lisp package contains implementations of a trivial demo server in ACL, LispWorks, CMUCL and CLISP. These should provide a good idea of how a CL network program is structured.
