SCO Unix Hints

Older SCO Unix versions

NTP 4.0.x does not run on SCO Unix prior to version 3.2.5.0.0. If you need NTP on an older SCO Unix system and don’t mind modifying your kernel, use 3.5.91 which has patches for SCO Unix 3.2.4.x.

Compiling NTP

Delete the old SCO supplied NTP programs using the custom utility. Run the NTP configure program with CFLAGS="-b elf -K processor-type" for best results.

---

Running NTP

Run tickadj -As after every reboot to set the variables clock_drift and track_rtc to the right values.

Run ntpd with a high negative nice-value, i.e. nice --19 ntpd for best results.
