Do you see the NTP request from the STB? And the response from the server? You need both for NTP to work. For example here I see:
187 17:41:47.670596 172.16.1.10 132.246.11.228 NTP NTP Version 4, client 188 17:41:47.704311 132.246.11.228 172.16.1.10 NTP NTP Version 4, server
This shows my client making the request followed by the server response. Do you see similar?
Only from the other PC, nothing whatsoever from STB filtering port 123.
Filtering on the STB IP, I see its IP (and server IP, since from it I telnet to the STB to run its shell) when I use it to ping Google. I also see Wireshark traffic to/from the STB using MC's FTPFS to manage its files. With time.nist.gov I tried in its GUI to make the STB sync after boot failed to sync automatically, and it failed twice, each time producing no additional Wireshark output. In its GUI I changed it to time.mit.edu and tried again. It succeeded in syncing but without producing any additional Wireshark output.
What filter were you using at that time? If NTP, then some other means is used to obtain the time. If filtering on IP address, then you must have seen something going to the time server address.
The whole paragraph was on the same IP filter ip.addr == 192.168.#.###. Not seeing anything whatsoever when having STB sync puzzled me too. I suppose there may be NTP broadcasting coming in on the satellite data stream that it might get it from, except if that were the case, providing a server URL wouldn't make any sense. Just now I did a capture restart with the same filter, then asked the STB to time sync again even though current appeared correct. It reported success, but nothing showed up in Wireshark. On rebooting STB, what first showed up in Wireshark was the Telnet session being closed, then stuff I don't recognize that could be Samba-related: http://fm.no-ip.com/SS/Tmp/azbhd-wires1421.png This boot succeeded to auto sync while NTP server config'd to time.mit.edu. -- "The wise are known for their understanding, and pleasant words are persuasive."
