    My HR20 is responding to pings and Tracert but does not give the expected error response when I Telnet to it. Did I miss the post regarding the Ping or do I have some other network weirdness going on?

    I have not had any other problems with it. (Knock on Imitation Wood Product)

    Ping not Pint (Fat Fingered another one)

    The HR-20 doesn't run a telnet service. What were you expecting to happen?

    I was expecting to see the all the Linux errata error message text like I have before when I Telneted to it.

    All I got was:

    HTTP/1.1 400 Bad Request

    Bad Request

    Connection to host lost.

    You should be able to telnet to any open port on a host.

    Try telnetting to port 80 on www.dbstalk.com. At the prompt, type "helo".

    Yes, but he just said "I can't telnet into the HR20" implying he's trying on port 23, and I can't imagine D* runs telnetd on the box.

    What port were to trying, TiredTeck?

    I would expect if anything is running on there that would let someone in, it would be ssh, not telnet.

    ...and yes ping has been enabled on the networked Driectv products, the Directv networked devices use to NOT respond to a ping.

    There use to be a test that coould be used with telnet that no longer works...

    c:/> telnet <HR2x IP Address> 49152

    This would go into a telnet timeout session because you hit an open port that did not know what to do with the telnet traffic. At the time out time, it would respond with some kernel linux details like what you were describing.

    See this LINK for details...

    I was using the 49152 port as specfied in the how to and posts.

    I did not get all the failure information back that I expected.

    I see, it's the port that Media Share runs on - the DLNA server is (was) just responding with an error.

    I understand now - thanks for the info.

    The telnet test is/was never really supported. It was something that was stumbled onto and was documented as a way to test the HR20 to make sure it was on the network with the expected configuration. Now that ping works, the "telnet <ip address> 49152" has been disabled to ginving out the information that it use to.

    Good to know that the Ping and Tracert do work.

    I like the way WMP11 properly identifies the DIRECTV Plus HD DVR on my computers now instead of just an "unknown device".

    tracert == trace route

    It's a network troubleshooting command which shows you all of the gateways (routers) that the request passes through between your source and the destination.

    Can you give me the details of how to use the command ? Is it just c>tracert {HR20 IP Address} ?
    I found this but any further comments appreciated.

    Isn't running traceroute to a device on your local LAN kind of pointless, or am I not taking something into consideration?

    Forgive me - it's early and the blood level in the caffeine stream is still kinda high...

    not if you're going through routers and switches, can be useful in determining issues.

    Not always. There are ways to block telnet access to a port.

    Hmm, no response to a traceroute from either of my DVRs:

    mac:~ bob$ traceroute 192.168.0.10
    traceroute to 192.168.0.10 (192.168.0.10), 64 hops max, 40 byte packets
    1 * * *
    2 * * *
    3 * * *
    4 * * *
    ^C

    Perhaps it has been disabled (I'm running the latest CE). Ping still works as expected.

    Oh - absolutely. Just figured most people only have a router to get to the internet, and everything inside their house is on the same subnet... A hop through a switch on the same subnet isn't going to show up on Traceroute.
