[ntp:questions] ntpd as a client when port 123 blocked

2014-04-26 Thread Rob
On a Linux system we ran into the problem that port 123 has been blocked for incoming traffic (probably as a general countermeasure against abuse of badly configured servers, this server was configured correctly). As it is not possible to change the source port number in ntpd, I translated the
