I tracked it down to problems in the adjtime system call, which seems to be so broken that there is no way to get ntp or xntp to run. Calls to adjtime to make small changes (microseconds) in the time-of-day result in a time that is too small by seconds. After a few hours of running ntpd, the clock is so far off that ntpd gives up. This is on AIX/370 with updates PTF U401122 installed (alias AIX/370 01.02.0300). We reported the problem to IBM at the end of October, but have had no reply yet. Until it's fixed, we are using the ntpdate program from the xntp distribution. The ntpd program does seem to run fine on AIX PS/2, after adjustment for the errors in conversions BOTH WAYS between float and unsigned long, and a fix for the little-endian placement of int:8. |> I haven't looked as much at our Silicon Graphics, but know (and have |> heard from others) that standard xntpd won't work. ... We are running ntpd on our Silicon Graphics 4D25s with IRIX 3.3.0, without any apparent problem. It has to be compiled for the BSD signal semantics: (in the Makefile: INCPATH= -I/usr/include/bsd LIBS= -lbsd -lmld CC=cc -g FEATURES= -DDEBUG DEFINES= -D_BSD_SIGNALS ) We haven't tried xntpd on the SGI's or IBM/3090. -- Paul Whaley Internet: whaley@ucs.ubc.ca Academic Operating Systems UUCP: ...!ubc-cs!mtsg.ubc.ca!Paul_Whaley University Computing Services BITNET: USERWHAL@UBCMTSG U. of British Columbia Phone: (604) 228-3976
