Q:  What is opennap?
A:  opennap is an open source server which speaks the napster protocol

Q:  What is napster?
A:  See www.napster.com for information.

Q:  Is this project associated with napster.com?
A:  No, this server was developed without any communication with napster.com

Q:  Why can't I connect to the Napster.com servers?
A:  We are not affiliated with Napster, Inc.  You should contact them for
    assistance.

Q:  What language is opennap written in?
A:  ANSI C.

Q:  How do I get more than 256 connections?
A:  On some systems without a poll() function, the maximum number of file
    descriptors that a process can have is controlled by the FD_SETSIZE
    macro.  If you only have select(), try rerunning configure with the
    --fd-setsize=1024 option to specify a higher value.

Q:  How do I get more than 1024 connections under Linux?
A:  You can set the per-process file descriptor limit dynamically by piping
    an integer to /proc/sys/fs/file-max
    (eg.  echo 8192 > /proc/sys/fs/file-max).  The default value seems to
    4096 which should be good enough.

    In order to utilize more than 1024 file descriptors, you must run
    opennap as root.  Set your `connection_hard_limit' variable to something
    higher than 1024 and you should be set.

Q:  Isn't running opennap as root a security risk?
A:  Running anything as root can potentially be a security risk.  Opennap
    attempts to reduce the risk by allowing you to specify the default
    uid/gid to run as.  After setting the max file descriptors, opennap
    calls setuid() and setgid() to drop root privilege (by default it uses
    user nobody, group nobody).
