This is a new port of OpenBSD's native ntpd to other Unix flavours adding autoconf support and the necessary compatibility layer. It is based on portability code from the OpenSSH and LibreSSL portable projects. OpenNTPD has a web site at http://www.openntpd.org/ The current portable tree can be found at https://github.com/openntpd-portable Platform Requirements --------------------- - adjtime(2) and settimeofday(2) syscalls or equivalent. - adjfreq(2) or an equivalent compatibility function for best results - daemon(3), setresgid(2), setresuid(2) or equivalent - A working arc4random(2) implementation, OpenSSL or LibreSSL (this project shares the same arc4random compatibility code from LibreSSL) At the time of writing the Portable version is known to build and work on: - OpenBSD (5.6) - Linux (Ubuntu 12.04, 14.04) - FreeBSD (9.x, 10.x) - NetBSD (6.1.5) - Solaris (10.x, 11.x) - Mac OS X (10.9) OpenNTPD may work on other operating systems, newer and older, but the above ones are tested regularly by the developer. Reports (success or otherwise) are welcome. You may report bugs or submit pull requests at the GitHub project: https://github.com/openntpd-portable Thanks, Brent Cook .
