Computer Science Department, Ames, IA Lines: 28 I know that "network time servers" exist on the Internet. Here's the list I have: 192.5.8.1 time 128.9.2.129 time1 isi 128.8.10.1 umd1 time2 128.5.0.1 ford1 time3 128.116.64.2 ncar time4 Now my question is how to use them. How does one ask any of these machines for the correct time? On which IP port number and using what protocol can I get the correct time? Port numbers I know of: 13, 37, and 525 (UNIX timed). I know that you can just connet to port 13 and read the time. What is the best way of doing this? Any help would be appreciated. My second problem is UNIX timed. My goal is to get the "correct" time from a time server and then pass it out on our LAN via timed. We have an HP 350 running HP-UX (System V/BSD "mix"). Has anyone ported the 4.3 BSD timed to HP-UX or SYSV? (This could be hard without the adjtime(2) system call.) Another option would be to use something other than timed. Any other comments or ideas are welcomed. /\ Dave Shaver -=*=- CS Systems Support Group, Iowa State University \\ UUCP: {hplabs!hp-lsd, uunet!umix!sharkey}!atanasoff!shaver \/ Internet: shaver@atanasoff.cs.iastate.edu
