I am currently operating an NTP server, and during the day, I only can devote a small part of my bandwidth to the NTP pool. However, during the night, since the line is unused, I can devote all my bandwidth to the NTP pool. Is there a way to set up time-dependent bandwidth limits? If there is not, I would recommend a system like this: Give all server operators a Base64 authentication code that uniquely identifies the server, and make a CGI script that takes as arguments the auth code and the bandwidth limit. Allow only accesses with IP address corresponding to the auth code. Therefore, server admins could put a wget to the CGI script in their crontabs, something like this:
0 20 * * * wget http://www.pool.ntp.org/admin/bandwidth.pl&auth=FOOBAR&limit=1024000 0 8 * * * wget http://www.pool.ntp.org/admin/bandwidth.pl&auth=FOOBAR&limit=512000 to set the limit between 8 PM to 8 AM at 1 megabit/sec and between 8 AM to 8 PM at 512kilobits/sec. _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
