Hello all. I am try to get the wakeuptorecord feature to work. I am following the steps on the wiki over here http://www.knoppmythwiki.org/index.php?page=WakeupToRecord.
At step 6 it recommends working as user mythtv. The trouble is that I don't know the password for user mythtv. I thought that I had made it so that there was no password in step 3. However I tried to log in as user mythtv with no password and this does not work so there must be a password.I can log in as root so I should be able to get the password, I just don't know where to look. Thanks in advance.

On my system, the mythtv user defaulted to a password of mythtv. I changed it. I also used that wiki article but then when 0.19 changed to using mythwelcome, which doesn't need the scripts. It means you don't have the problem of exiting the frontend and not having an easy way to get back in. I've been meaning to edit that wiki to show the mythwelcome instructions. You can find instructions for mythwelcome at http://www.mythtv.org/wiki/index.php/Mythwelcome

what steps do I need to follow in the old wiki. You mentioned that I don't need the scripts. I have done up to step five. Also, would it just be easier to wait until you change the wiki? Thanks for the heads up about mythwelcome.

I have copied the existing wiki and edited it for configuration with MythWelcome in a new page at http://www.knoppmythwiki.org/index.php?page=WakeupToRecordWithMythWelcome. I haven't done this for a few months so it might need editing.

Alright. Looks like I'm your guinea pig. As user mythtv I entered

Code:
sudo nvram-wakeup -s $((`date +%s` + 900))


as shown in the first part of your step 4.

This is the output that I received:

Code:
>>> sudoers file: syntax error, line 7 <<<
>>> sudoers file: syntax error, line 9 <<<
>>> sudoers file: syntax error, line 11 <<<
>>> sudoers file: syntax error, line 13 <<<
>>> sudoers file: syntax error, line 14 <<<
>>> sudoers file: syntax error, line 16 <<<
>>> sudoers file: syntax error, line 19 <<<
>>> sudoers file: syntax error, line 21 <<<
>>> sudoers file: syntax error, line 24 <<<
>>> sudoers file: syntax error, line 24 <<<
sudo: parse error in /etc/sudoers near line 7


Here is the contents of my edited /etc/sudoers:

Code:
# sudoers file.
#
# This file MUST be edited with the "visudo" command as root.
#
# See the man page for details on how to write a sudoers file.
#

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root   ALL=(ALL) ALL

# KNOPPIX WARNING: This allows the unprivileged knoppix user to start commands as root
# KNOPPIX WARNING: This is totally insecure and (almost) makes knoppix a second root account.
# KNOPPIX WARNING: Never allow external access to the knoppix user!!!
knoppix   ALL=NOPASSWD: ALL

# changed for nvram-wakeup
#mythtv ALL=NOPASSWD:/usr/sbin/nvram-wakeup,/usr/bin/mythshutdown,/usr/local/bin/kmhalt.sh,/usr/sbin/hibernate,/usr/bin/eject,/s
bin/halt,/sbin/reboot,/bin/mount,/bin/umount,/usr/local/bin/mythbackup,/usr/local/bin/mythrestore,/etc/init.d/mythtv-backend,/usr/local/sbin/hibernate

mythtv ALL=NOPASSWD:/sbin/halt,/sbin/reboot,/bin/mount,/bin/umount,/usr/local/b in/mythbackup,/usr/local/bin/mythrestore,/usr/sbin/nvram-wakeup,/sbin/lilo


I noticed that at the top of the file it says that
Quote:
This file MUST be edited with the "visudo" command as root.


I haven't done anything like this, nor do I know how to. Could this be causing the error?

Actually from the looks of what you posted you corrupted the file in some interesting way. I see what looks two line breaks that don't belong there (one in s<LF>bin and one in "b<LF>in"). What did you use to edit this?

I used WinSCP to get it on my Windows box and then used WordPad to edit it. I think I found the problem. In the wiki page the line that has to be inserted

Code:
mythtv  ALL=NOPASSWD:/sbin/halt,/sbin/reboot,/bin/mount,/bin/umount,/usr/local/bin/mythbackup,/usr/local/bin/mythrestore,/usr/sbin/nvram-wakeup,/sbin/lilo


is split up. I now made it one line before I put it in the file. Now when I run
Code:
sudo nvram-wakeup -s $((`date +%s` + 900))

as user mythtv I get the following:

Code:
nvram-wakeup: Your mainboard is currently not supported.
nvram-wakeup: Please try determining the addresses and sending the following
nvram-wakeup: information back to the maintainers:
nvram-wakeup:  - The addresses you found out (read README.mb)
nvram-wakeup:  - Mainboard vendor:
nvram-wakeup:  - Mainboard type:     1234
nvram-wakeup:  - Mainboard revision: 9189g10001
nvram-wakeup:  - BIOS vendor:        Award Software International, Inc.
nvram-wakeup:  - BIOS version:       6.00 PG
nvram-wakeup:  - BIOS release:       10/17/2001



I have run guess-helper and then
Code:
nvram-wakeup -C nvram-wakeup.conf

after copying the file to the /etc directory. I can post a copy if needed.

Editing Unix scripts and configuration files with Windows editors is a sure recipe for strange problems. ;-) MS-Windows has a nasty habit not just of sticking CRs in where Unix only expects a LF but also of including other invisible whitespace characters in places where they don't belong. VTs are another favorite which often have people ready to tear their hair out in large clumps. But even extra spaces at the end of a line can cause people grief.

I fix at least one of these a week for someone at work. I even configured my editor to show trailing whitespace and special characters in bright orange inverse video to make it easier. It looks incredibly ugly, but it makes potential problems really hard to miss. ;-)

I've posted a simple one line file cleaner in various threads around here for dealing with just this kind of issues....

Alright - some progress:

I realized that I had to include the
Code:
-C /etc/nvram-wakeup.conf

in the command.

So I then issued the command:

Code:
sudo nvram-wakeup -s $((`date +%s` + 900)) -C /etc/nvram-wakeup.conf


as user mythtv.

I then did a
Code:
sudo halt

as directed in the wiki. The computer turned off and then came back on again about 10 min later (5 min less than I had told it to, but no sweat there.) However here is where I hit the problem. The BIOS spits the following error message.

Quote:
CMOS checksum error - Defaults loaded


I can press enter to boot, but that would defeat the whole point of auto-wakeup. When I actaully go into the BIOS and manually set a time to wake up everything works great. Any ideas?

PS - In case it helps here is my /etc/nvram-wakeup.conf
Code:
################################################

I had to comment out one addr_stat because there were two. Perhaps I should try the other one?
and here is my /root/guess-directisa/guess-error.log

Hi. Are there any German speakers out there who would like to give this a shot? A google search http://www.google.com/search?hs=clY&hl=en&lr=&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&q=nvram-wakeup+CMOS+checksum+error&btnG=Search
for nvram-wakeup CMOS checksum error leads to a number of responses but the ones that seem to be most relevant are in German. I would REALLY appreciate it if someone could look into the first few pages a bit and see if
they can spot my error.

Alright! I flashed the BIOS to version 1.03 and reran the nvram-wakeup guess-helper. Now wake up works!!
