This showed up in /myth/video on my be/fe

drwxr-xr-x 4 mythtv mythtv 4096 Sep 12 22:28 myth

The mythtv mythtv has me puzzled.
I deleted the files and directories. I wanted to make sure they weren't copied somewhere else and so I did a search using:

# ls -lR / | grep "Sep 12 22"

-rw-rw---- 1 mysql mysql 212 Sep 12 22:00 cardinput.MYD
-rw-rw---- 1 mysql mysql 5308 Sep 12 22:00 record.MYD

Nothing shows up in history to suggest copying.
I believe at that time, Sep 12 22:27, I was working on my fe only trying to get dvd's to play, which I did, and dvd's to rip which I didn't.

After connecting to a box via ssh and then becoming root, how do I become mythtv in order to check its history?

As I've been writing this I'm thinking maybe the copy was done via samba, is that possible as the directories were owned by root?

I was able to read the history via:
# less /home/mythtv/.bash_history
but found nothing unusual.

Samba logs were blank and /myth is not accessible at this point from my XP box.
Both boxes, be/fe and fe only, are R5F27.

# grep "Sep 12 22:2" /var/log/*
/var/log/auth.log:Sep 12 22:25:01 mythtv2 CRON[7964]: (pam_unix) session opened for user root by (uid=0)
/var/log/auth.log:Sep 12 22:25:01 mythtv2 CRON[7964]: (pam_unix) session closed for user root

looks like it was copied, by a mythtv user process. cp'ed files take the ownership from the user doing the cp.


coping from / is possible as all of the files, directories have the 'R' bit turned on.

You dont need to become mythtv user to see mythtv's history. cd to ~mythtv (that user's login directoy) and look for the shell history files
Code:
ls -al

or simply
Code:
ls -al ~mythtv

If you want to 'become' a different user...
Code:
su - mythtv

You know, I saw this exact same thing, too, and I figured it was something I'd done while messing around with things. If you've seen the exact same thing, then something in R5F27 must be doing this. At least we know we're not crazy now :)

Thanks khrusher and Human

Yea, I double checked all .bash-history files and could find nothing.

Also had another strange thing happen last night, Sep 12. From my XP box I vnc'd into my be/fe and it wouldn't accept my password that I had put into /home/mythtv/.fluxbox/apps

I had to use mythtv as the pw. I just checked that file for creation date:
# ls -l /home/mythtv/.fluxbox/apps
-rw-r--r-- 1 mythtv mythtv 416 Sep 10 15:12 /home/mythtv/.fluxbox/apps

And today I can use the password that I put in there. Strange.

EDIT: Sorry, I misunderstood what you meant. You're referring to the feature where you insert a CD or DVD and extract the videos from it. I used this feature, too. This seems to be the culprit.

No, not the thumbnail generator - That's under the /setup menu. In the Optical/DVD menu. I clicked thinking it was a neat way of importing downloaded stuff (an avi for example) into video folder. The thumbnail generator worked fine.

Oops, you beat me to it.

Wow, the script is just this:
Code:
#!/bin/bash
cp -R `cat /proc/mounts |grep iso9660|awk '{print $2}'|tail -1`/* /myth/video/

As you can guess, if the expression evaluates to null, the command becomes
Code:
cp -R /* /myth/video/

Doh!

I don't know who wrote it, but I'll fix that up and add the fix to R5F27's live patcher.

Everyone please try replacing /usr/local/bin/importfiles.sh with this rewrite and post results.
Code:
#!/bin/bash
export FONT="-adobe-helvetica-bold-*-*-*-34-*-*-*-*-*-*-*"

DVD_or_CD=`cat /proc/mounts |grep iso9660|awk '{print $2}'|tail -1`
if [ "$DVD_or_CD" != "" ]; then
    echo "Copying files from $DVD_or_CD to /myth/video." > /tmp/screens
    echo "This could take several minutes, depending on the" >> /tmp/screens
    echo "speed and size of your optical media." >> /tmp/screens
    cat /tmp/screens | osd_cat --font=$FONT --shadow=3 --pos=middle --align=centre --delay=0 &
    /bin/cp -R $DVD_or_CD/* /myth/video/
    killall osd_cat
    echo "Copied videos from $DVD_or_CD to /myth/video" > /tmp/screens
    cat /tmp/screens | osd_cat --font=$FONT --shadow=3 --pos=middle --align=centre --delay=2 &
else
    echo "No optical media found.  If you just inserted" > /tmp/screens
    echo "your media, please wait a moment and try again." >> /tmp/screens
    cat /tmp/screens | osd_cat --font=$FONT --shadow=3 --pos=middle --align=centre --delay=5 &
fi

I tried the new script and am getting the "No optical media found" message. I then tried just playing the dvd and that was successful. Tried a different one with same results.

I had in fact tried the "Import Video Files ..." last night.

Did you put in a DVD of individual video files?

I tried two commercial dvd's and one homemade vcd. All 3 played on the FE, but only the vcd played on the BE/FE because the region setting or whatever hasn't yet had an attitude adjustment. As for "Import video file", both boxes gave the same response on all three disks of "No optical media found".

The feature we're talking about is to copy video files that were burned to DVD or CD media, not a rip of a DVD or VCD. In any case, since it's no longer copying / to /myth/video, it looks like it's working.
