Hello all,
I'm running Fedora Core 2 and trying to get ntp working.
Code:
# /etc/init.d/ntpd restart
ntpd: Geöffnete Firewall für 194.42.48.120 port 123 entfe[ OK ]
ntpd: Geöffnete Firewall für clock.tix.ch port 123 entfer[ OK ]
ntpd herunterfahren: [ OK ]
ntpd: Firewall öffnen für Eingabe vom 194.42.48.120 port [ OK ]
ntpd: Firewall öffnen für Eingabe vom clock.tix.ch port 1[ OK ]
ntpd: Mit Zeit-Server synchronisieren: [FEHLGESCHLAGEN]
ntpd starten: [ OK ]
Everything is working ok, except the synchronization.
Yes, I am behind a firewall and as you can see from the above output, it automatically gets deactivated for this action. I made sure that the firewall is not in cause by totally deactivating it and I still had the same problem.
Then I made a tcpdump in order to see what's going on on this level:
Code:
# tcpdump -v -ni eth0 port 123
tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
16:52:38.065482 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto 17, length: 76) 10.218.226.11.ntp > 194.42.48.120.ntp: NTPv4, length 48
Client, Leap indicator: clock unsynchronized (192), Stratum 0, poll 4s, precision -6

Originator - Transmit Timestamp: 3306667958.065328001 (2004/10/13 16:52:38)
There are several occurences of this kind of output, but then again, I don't know too much about ntp and have no idea how I could interpret them.
Any insights very much appreciated.
