DirecTivo with 1 fried sat input? |
|
|
Greetings. My dad's Hughes 80-DVR80 DirectTV Tivo had an unfortunate
meeting with a lightning storm and an (ahem!) ungrounded dish, which
caused the satellite in #1 port (the only one in use at the time) to
fail. The unit performs just fine other than that it can't find a
satallite signal, so I'm going on the assumption that the RF section for
sat1 input is what's fried.
Is there a way I can tell the unit to use the hardare for the sat2
input, and have the software think it's sat1? I'm comfortable with all
things Unix-ish if this could be some sort of "put in a symlink from
/dev/sat1 to /dev/sat2" kind of deal, or even more complex but
documented-ish hacks.
So, can I turn this back into a Tivo, or is it time to learn about
ethernet cards and all that fun stuff, and turn it into a utility linux
server in the basement on the network somewhere?
Thanks,
Dave Hinz

Have you swapped the cables around? Are you sure that input is dead? As
in, take the cable from the working port and put it, by itself, on the other
port (leaving the first one disconnected). Make sure it's the Tivo, not the
downlink from the satellite or any multiswitches in-between.

It's got a slow processor and not much RAM. It doesn't make for all that
great a 'utility' server. Better to use an old 128mb/400mhz desktop machine
instead. If the Tivo's crapped out then yank it's IDE drive and re-use it
on the PC. |

Yup. Put a known good dish on it (well, took it to my house) and it
also can't see that. The known good tivo (mine) also didn't see the
dish, so the dish (lnb or whatever it's called these days) _and_ the
tivo got the zap.

Yup, did that but I should have mentioned it in my post.

Well, if it's just for serving mp3s and such, it'd be reasonably fast
enough? Hell, maybe a print server, or load it up with ipfw and turn it
into a dedicated firewall... |

No, it's not fast enough to serve mp3s. I'm not sure it could even be a
good firewall, depending on how complex your rules are and what type of
traffic you have. print server? maybe, but it would be slow and not
really worth it. Seriously, that box is not good for general purpose
computing by any respect.

Wouldn't a firewall need two ethernet ports? |

Ah, so I can't add two interfaces then? Hm. This thing worth anything
on eBay as-is? |

Not necessarily. Look up 'IP aliasing'

You can't add two interfaces no.
Yes, it is worth something as-is. Of course, you could just go to
ebay.com and see what's there, but as a general rule, all TiVos have value
on eBay - working or not.

im familiar with it if its the same as ip spoofing based firewalls, but
still
it's not really what i'd call a true firewall and it's limited in its
capabilities
for incoming traffic. i'll look it up when i get a break here at work. |

Sure you can, if it's got USB that is. Can't recall which model DirecTV
units do or don't have USB. But if you've got a series 2 style unit that
has USB ports and you're already hacking it for one device then you could
just as readily add another (note I didn't say easily).
It's a matter of hacking it to get the ethernet/usb driver working so once
you get up over THAT hurdle it's not much harder to add another.
But if this isn't a series 2 with usb then you're stuck with only one. I
suppose you could get clever and setup PPP via the serial port but, yeesh,
talk about crappy performance....
The point, however, would be why bother? It's dog-ass slow for anything
other than it's designed purpose. These units are built to do nothing other
than feed the video encoder chips. Couple that with trying to use the
single USB controller for dual ethernet ports and, well, it's just not worth
it for much other than proving it's possible, not that it's useful.
Basically, it sounds like that unit is toast. Yank the drive and use it on
a PC.
Since they're already DirecTV customers call up customer service and wrangle
a deal on a new unit. They're more interested in keeping customers than
gouging full retail for units. There's plenty of deals to be had, remember,
"if you don't ask, you don't get".
