ISP PAP modem fix

[petestrash]

Thanks for your work on this, I'm sure it will be handy for many people who still use dialup.

I have corrected the wiki link in your post as the tag and name were reversed, so the link did not work.

I also added a link back here from the wiki.

Thanks for fixing up the link and linking back petestrash.

I'm not sure if there will be much demand for this fix, but it might be worth making a script to run on the tivo to automatically apply the patch?

Hi, thanks for working out how to do this! Now I can use (Dad's) very cheap dialup (E3.net.nz) instead of expensive Paradise dialup. I have a few tips for people.

If you are using dialup you probably wont have a network card and therefor no FTP. You will need to enter the following commands in Tera Term via a serial link instead. commands are in bold. lower case is important.

rw
cd /tvbin
cp tivoapp tivoapp.bak
stty speed 57600 then change the speed in TeraTerm; 'Setup' menu, 'Serial port...', 'Baud rate' to 57600. Otherwise it will take forever to transfer the file at 9600. You could try 115200 instead but it will probably fail during file transfer.
sz tivoapp then in Teraterm go to 'File' menu, 'Transfer', 'ZMODEM', 'Receive...'. The file will by default be copied to your TeraTerm folder.
Edit it with a hex editor, as described by catdog, then copy it back:
rz In TeraTerm 'File' menu, Transfer, ZMODEM, Send... and browse to the file you edited called tivoapp.isp. After 10min or so the file will hopefully have got to 100% and finished.
rm tivoapp
mv tivoapp.isp tivoapp
chmod 755 tivoapp otherwise gets stuck at bootup screen.
Now edit ppp-options chap-secrets pap-secrets tclient.conf with the ISP phone number, user name and password, as described here http://minnie.tuhs.org/twiki/bin/vie...thBuiltinModem.
ro
reboot

I guess I won't need the Terbonet cards I'll be building in two weeks...just kidding.

I'm running 3.0 v1.4 but will be upgrading to NZv1.6 soon to fix having to reboot to index guide data, and seasons-passes and browse-by-title not working.

Will the mod'ed tivoapp also work for ISPs that just use plain text [login] authentication?

I assume that we need to FTP tivoapp in binary mode (right?).


Also, it would be good to list the ISPs that do/do not need the mod'ed tivoapp.

A start (prefixed by country):

* tivoapp mod not needed:
NZ-PlaNet
NZ-xtra (needs confirming?)
NZ-paradise.net (needs confirming?)

* tivoapp mod needed:
?

Just found some related info at this post:

which suggests that the mod works for many NZ ISPs.

This mod bypasses the plain text login procedure - if your ISP only needs a plain text login then there is no need to implement this mod as the standard tivo files can handle that ok.

On saying this, an ISP which does plain text (eg xtra) will almost certainly also support PAP if the tivo initiates it, so the mod should not break anything.

Yes, it is a binary file. Also make sure the new file on the tivo is executable as Skolink pointed out (chmod 755 tivoapp) - the FTP program may do this for you automatically.

The trouble is that ISPs tend to change things with out telling anyone (and windows machines dont need to be reconfigured after each change so most people dont notice).

Yep - works on every NZ isp I have tested: slingshot, e3, xnet, xtra.

For info, it turns out that NZ Xtra *requires* catdog's tivoapp fix (thanks mate!). I also tried maxnet, which did not require the tivoapp fix.

To make things easier (and quicker over a serial connection) the hack can be done without having to copy the file to PC.
Use at your own risk.
The commands to enter are in bold. Make sure the filesize is reported as 6575372 after entering the first command before continuing with the remaining commands.

[TiVo [p0] ~]# ls -al /tvbin/tivoapp
-rwxrwxr-x   1 0        0         6575372 May 30  2002 /tvbin/tivoapp
[TiVo [p0] ~]# rw
File system is now READ/WRITE.
[TiVo [p0] ~]# cp /tvbin/tivoapp /tvbin/tivoapp.isp
[TiVo [p0] ~]# echo -ne "\x0" | dd conv=notrunc of=/tvbin/tivoapp.isp bs=1 seek=5321383
1+0 records in
1+0 records out
[TiVo [p0] ~]# echo -ne "\x1" | dd conv=notrunc of=/tvbin/tivoapp.isp bs=1 seek=5321647
1+0 records in
1+0 records out
[TiVo [p0] ~]# mv /tvbin/tivoapp /tvbin/tivoapp.bak
[TiVo [p0] ~]# mv /tvbin/tivoapp.isp /tvbin/tivoapp
[TiVo [p0] ~]# chmod +x /tvbin/tivoapp
[TiVo [p0] ~]# ro
[TiVo [p0] ~]# reboot

If you experience problems, make sure your ISP details are correctly set in the following files (the installer cd should do this for you if the modem option was selected):
/etc/tclient.conf - telephone number
/etc/ppp-options - username
/etc/pap-secrets - password
Details can be found in the oztivo wiki
