Network Problems when extracting via Airnet

[netlizard]

ok, This all started when my system got upgraded to 3.1.0b. I used the nic_install cd to get the network back and bash access. That worked, I could get bash and ftp access. The problem was that when I ran the tserver_mfs7 and tried to get streams via tytool, it would hang after just a few bytes of data and then all of the networking would quit working...

I have since built a disk using 25xtream and then Tivo upgraded it to 3.1.0b again and I was in the same situation. Now I have created another disk built with 25xtreme and xupdate to 3.1. It is staying on 3.1.0 but I am also in the same situation with tytools and tserver_mfs7.

It is a networking problem, but I can't figure out what.... I have tried both fixed IP and dhcp. Neither works.

Please help, I am running out of ideas. I did load and insmod noscramble.o so that isn't the problem...

I can't really help here, I have a similar problem. I thought someone smarter might spot something.

UK Tivo 2.5.5 etc. original HDDs. No mods except for
adding an AIRNET card.
IP 172.31.254.xx
NM 255.255.255.0

All networking (ping, telnet, ftp and getting NowShowing info etc., even pinging from the tivo side) works fine until I attempt to get a stream from it. At this point the networking appears to lock up at the tivo side.

The Tivo UI remains functional.
Only a System Reset recovers.

Seems to happen with tytool 8r3 and 7r10 and the ones before.
Also, noticed it happens with tystudio and I think it was the webserver's view onto the mfs or using mfs tools. Everything is fine until I select a stream to get, then lock up at tivo networking side. Tivo UI continues to work fine!

Tried installing TurboNet stuff and then overwriting with AirNet install, in case there was something missing from the AirNet setup. No diff.
Noticed that the default GW never changes from 192.168.1.1 even though I set it to 172.31.xx.yy! Although, on the Tivo, there is only one network route to the local LAN.

I have read the related posts but none of them suggest an answer. The nearest one so far was one chap with a tivo on 192.168.2.xx.

Has anyone successfully extracted a stream from an airnet enabled UK tivo? If so, was it NOT on 192.168.1.xx?

Either way, can you shed some light on this, please?

The gateway should change - try running the config program (nic_config_tivo IIRC) to alter it, or use the manual command.

route.tivo add default gw xxx.yyy.zzz.www

You're not spelling out the full IP addresses so it's hard to be sure (no need to xxx them out for internal ones!), but is everything on the same subnet?

[philips]

I have tried adding a route manually with route.tivo add default gw 172.31.254.1 previously, but the same hang up happens.

I have just tried running nic_config_tivo and it still shows the same gw address of 192.168.1.1. Even when I change it, apply it and then rerun nic_config_tivo!
The routing table however is correct according to the manual change I made.

Also, everything is on the same LAN
Here is what nic_config_tivo shows about my setup (gw is wrong as usual)

Current/New Configuration:
timing setting = failsafe
SSID = wlan
encryption = 128bit
key = XXXXXXXXXXXXXXXXXXXXX
ip address = 172.31.254.77
ip subnet mask = 255.255.255.0
ip gateway = 192.168.1.1
debug level = off
daily call = dialup

Here is what route.tivo -n shows (route.tivo on its own crashes with illegal instruction). The default route was added manually.

route_info, afname=inet, options=37
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.31.254.0 0.0.0.0 255.255.255.0 U 32767 0 0 eth1
0.0.0.0 172.31.254.10 0.0.0.0 UG 0 0 0 eth1



here is the output from ifconfig

I notice that netlizard and jdiner are working on a similar problem in another thread (http://www.dealdatabase.com/forum/showthread.php?threadid=28314), but they seem to have an issue with version 3.1.x

Anyway, I hope the info above helps in some way. I just get the feeling I missed something really important that everyone else didn't!

Here is something extra I tried to rule out MFS access problems.

Extract a tystream. Doesn't really matter what one and direct the output to null.

./mfs_stream -s 1871827 > /dev/nul

This will read the entire thing from the MFS and write it to the bit bucket so no extra disk space is needed.

If this works then it is a networking issue. If this does not work then it is an accessing the MFS issue. And if it is the MFS we are in for a world of hurt as more and more people get upgraded until someone can figure out what is going wrong.

If its useful, I tried this and can export the stream, see output below.

bash-2.02# mfs_stream -s 1647567 > /dev/null
exporting fsid 1647567 of size 9437184 to stdout
bash-2.02#

But when done from the network (tytool etc) it hangs the network after the 'exporting' message.

[sanderton]

Have you tried using mfs_ftp?

Problem sorted now.

I tried all of the different methods for extraction I could think of (TyStudio, mfs_export, TyTool), but all failed at the same point.

Turns out there is something wrong with my AirNet card (DLink DWL-650 from 9thTee).
The card works fine until the Tivo tries to send more than about 1.5K of data at once!!! Then it hangs up.
Stuck it in an XP box and it seems to work alright (firmware/station versions 1.1.1 and 1.5.6 - can't remember which is which), got a Win98 box and it blows up the same as the Tivo.

Took me this long to reply because I had to buy a new PCMICA card (NetGear MA-401 from PC World) which worked straight away.

Don't know what is wrong with the DLink card, but it screws up when I try to extract a stream. ALL OTHER NETWORK ACTIVITY WORKS - so if anyone else is having stream extraction problems, where the network seems to hang up the moment you try to get the stream, then SUSPECT YOUR NETWORK CARD.


Thanks to everyone who offered help and suggestions - all much appreciated.

If you do a search for extraction with Airnet you'll find a lot of comment about this. I never got a 100% extraction with Airnet, irrespective of the extraction tool, switched to ethernet and now it's fine. When you are extracting, bif chuncks, you are asking mor than this driver can deliver, as opposed to a mor gentle telnet session or guide data d/l

There are lots of tweaks you can do to the Wireless config that might help. Unfortunately, it seems to be a crap shoot as to which ones will help. Why not post a question on the vendor's support line asking about large file xfers and see what they recommend?
