Hello all,

Is there any way to get the OS time of a remote node programaticaly?

Since you didn’t specify a language, how about shell script?

#!/bin/sh
if [ “$1” = “” ] ; then
echo $0: you must specify a node
exit 1
fi

on -n $1 date

:wink:

I’d like to do that with a small program writen in “C”.

You might want to peek into source code of spin. It has code to do that,
albeit somewhat crude.
It’s on the 3rd party CD…

Another option would be to run an NNTP daemon, and get the
clocks synchronized on all your machines.

I think you mean NTP

But could also just run inetd and connect to the time service, which
spits out a time_t I believe

You could do it with NNTP – there’s a date command :slight_smile:

I found an easy way, if you’ve got QNet running… use stat() on
/net/{NODE_NAME/proc/1 and check st_mtime.

Attached is a C++ project (don’t worry, it doesn’t use any of the wacky
C++ features like iostreams or templates) for the IDE that creates a
“nodetime” command. Use it with “-n node_name” to get node_name’s
current time.
