Would you please *add* the good reasons to a comment in the code just before the definition of move_fd() when you get a chance? There are *plenty* of undocumented cases where we do something for a good reason nobody can remember anymore. > However, if for some reason this causes a problem on his > particular O/S we can create a conditional macro to have it not use it. And until somebody besides you knows the good reason for move_fd(), nobody else will know if disabling move_fd() for AIX will be a good thing or if it will trade one problem for another (in this case, the underlying reason for having move_fd()). > > I think it has to do with making sure there is room to open different sorts > > of files, and may only be important if one has refclocks. > > > > But it could be Bad to disable move_fd() in general for AIX. > > > > We don't know the general case to be able to answer that one. OK, so again, when the underlying reasons fo having move_fd() are documented (and therefore better known) in general, we have a chance of coming up with a better answer for this, too. > > As for IPv6, are there any versions of AIX where IPv6 is working? > > Yes, IPv6 does work on AIX.

If there are known problems/issues with things like this, I would strongly request that people add this sort of information somewhere. It could be the code, or it could be at http://support.ntp.org/Dev . If we can figure out which versions of the OS do what, and if we can determine what OS version we have at runtime, we can have a single AIX executable DTRT depending on the OS verison (or patch level).
