What am i missing here......when running an snmpwalk the modems are returning time and date as "unset". I am using a nortel cmts 1000 and motorola 4100 cable modems at each property.....do i need to recheck my cm config files? I have set the config in the nortel and on the cisco 2611 router properly to point TOD/NTP at the main NTP server ......fyi, there is a gre tunnel route from the NTP server to the cisco 2611 router used for snmpwalks on the cable modems.....i can ping the cable modems private ip and the public cpe ip range at each property from the NTP server. I have also verified that the NTP server is not restricting the CMTS or Cisco router from TOD syncing. Please advise...if you can.
I believe the modems are looking for Time of Day, (the time-udp service in unix that runs on UDP/37). It sounds like you're pointing them towards a NTP server (network time protocol that runs on UDP/123). Does the NTP server also run a time service? If not, that's the problem.
no , the Time of day is not the same with ntp , you can use linux to build a time service .
you can see the RFC 868, port number is 37 (UDP)
Can you steer me in the right direction when configing on a centos or red hat server..........maybe even paste a config........Thanks.
Where there's a wire there's a way.
fedora is in /etc/xinetd.d/time-udp
i have change to use docsis_server in Centos , the docsis_server is include a time service .
can you paste the config file?
what kind config ?
just enable the time-udp service ...............................................................................that is config .... Orz
