unix-domain-socket-dir
Solaris requires special code for interprocess communication, and
it needs to use unix domain sockets. If you're running Solaris,
you must set unix-domain-socket-dir to a directory that the server
can write several little files to. If your operating system is not Solaris,
this variable is ignored.
Examples:
unix-domain-socket-dir=/usr/local/etc/ncftpd/ipc
unix-domain-socket-dir=/var/run/ncftpd/ipc
Recommendation:
unix-domain-socket-dir=/usr/local/etc/ncftpd/ipc
