    8.19: Why doesn't my sockets program work under System V (Solaris)? What does the error message "Protocol not supported" mean?

    Some Sys-V based systems, notably Solaris 2.X, redefined some of the
    standard socket constants. Since these were constant across all
    architectures, they were often hardwired into perl code. The proper way
    to deal with this is to "use Socket" to get the correct values.

    Note that even though SunOS and Solaris are binary compatible, these
    values are different. Go figure.

    are not necessarily experts in every domain where Perl might show up,
    so please include as much information as possible and relevant in any
    corrections. The perlfaq-workers also don't have access to every
    operating system or platform, so please include relevant details for
    corrections to examples that do not work on particular platforms.
    Working code is greatly appreciated.
