I'm behind a firewall and only have access to ports 80 and port 443.
How can I sync my system's clock?
Here's the command I issue:
sudo ntpdate -u 1.debian.pool.ntp.org
But I keep getting the following error:
no server suitable for synchronization found.
Is there some other program that can sync over port 80/443? Or is it possible to get ntpdate to work on these ports?
Many thanks in advance,
