NTP on SuSE 9.3

I just spent a few hours trying to get an NTP server working on SuSE 9.3. Correction: I spent most of this time getting the SuSEfirewall2 to allow NTP traffic. Apparently, this can't be configured through YaST in SuSE 9.3 but you have to edit /etc/sysconfig/SuSEfirewall2 and add these two parameters:

# Obviously, you have to configure the external interface to allow NTP UDP datagrams
FW_SERVICES_EXT_UDP="ntp"
# ...but you also need this to get the NTP server working
FW_ALLOW_INCOMING_HIGHPORTS_UDP="ntp"
