Kobo Start Menu 07

Hello AlterusPrime, I am glad you like KSM.

Like make a script that would wget books from, for example, http://192.168.1.2 (there's a HTTP server running HFS, generates a webpage with links) to some specific folder, like /mnt/onboard/.books/wgotbooks? If it's possible - could you possibly assist me in achieving this?

Do the other wget scripts work? I am asking just to make sure that the wifi connection is working.

How exactly are you trying to download your files? I guess you will

• download an index file from the server with wget
• retrieve the available file names from the index file
• select those file names that have not a counterpart in /mnt/onboard/.books/wgotbooks
• download each selected file with wget

If you are doing it in this way (or similar), you could write the results of each step to a log file in order to find where the error occurs. Or you can run your script via telnet to see what is happening, or you can execute each command individually from telnet.

Just a cosmetic thing but things like that always make us feel more comfortable, right? To do so - should i rename some script or is it not that easy?

You would have to do some changes in .adds\kbmenu\onstart\ksmhome.sh. But take care, rcS and this file are the two critical scripts in KSM. A mistake can force you to factory reset the reader. And since ksmhome.sh is likely to be overwritten by future updates, you would have to be applied the changes again and again. On a side note, "start vlasovsoftlauncher" does exactly this, it does not start coolreader.

rsync!

(No, seriously, rsync is awesome for this kind of stuff, it'll do all the heavy-lifting for you ).

*Hic-up*

zsync it is already in Koreader.

Or an OPDS server.

Thanks for your response tshering,
Yes, preset scripts do work perfectly, there's no issue with that.
The thing i'm trying to achieve is: script gets index -> extracts all the files from <a> tags -> downloads them and rewriting existing stuff in the folder.

Now about logging. I was wondering if that's possible to log things into some file 'cause i really want to write the script by myself (just to prove something to myself, and, of course, get the task done), could you possibly tell me how to do the logging?

About vlasovsoftlauncher. Thanks for pointing me to the ksmhome.sh, and yeah, i do understand that VSL doesn't start coolreader by default but i do have "autostart" options in VSL set to Coolreader, so in my case it actually does start Coolreader.

NiLuJe, thanks for advice, i'd definitely look into rsync, it seems even more fitting than wget for that task (if i'll find out how to use it on kobo lol)

Ken Maltby, i was thinking about OPDS stuff but unfortunately i don't use Koreader and Coolreader doesn't actually have an OPDS feature. So that's not my way to do things here. But thanks anyway

UPD: edited ksmhome, got rid of long line, got rid of that rocket icon, changed it to book, set autostart to 3+coolreader - user experience improved.
UPD2: found the kbterminal thing (why didn't i see it earlier? i think i was blind or tired. or even both.), gotta try to debug my script through this.

I would do something like this (it is only the basic idea, not the full code)

Spoiler:

#create name of log file
debug_logfile=/mnt/onboard/wgettest_$(date +%Y%m%d_%H%M%S).log

# only examples
$theurlbase=http://mybooks.com
$targetdir=/mnt/onboard/.books/wgotbooks

#remove index.html if it exists
rm -f $targetdir/index.html

#log what you are going to do
echo "wget -O $targetdir/index.html  $theurlbase/index.html" > $debug_logfile

# do it now for real
wget -O $targetdir/index.html  $theurlbase/index.html

# save the exitcode into a variable
theexitcode=$?

# if exitcode is not 0 log it and exit the script
if [ "$theexitcode" -ne "0" ]; then
  echo "exitcode: $theexitcode" > $debug_logfile
  exit
else
# parse index.html for links
# remove those links that point to files already downloaded earlier
# or if you want to download updated files that have the same filenames as the old ones,
# it seems you have to download all files and compare them to what is already on the device
# [ some code ]
# loop through the links and try downloading them with wget
# log it in the same way as above
# in order to save time during the first trails, maybe write only the log messages
# without actually trying to download
# [some code]
fi

I guess kbterminal is not very useful for this task, do it by telnet if this is possible for you.

As for rsync you can find a compiled version in Yet another telnet/sshd & misc tools package... (kobo-stuff-1.3.N-r11910.tar/KoboStuff/KoboRoot/mnt/onboard/.niluje/usbnet/bin)

Thanks very much for your KSM and updates.

I have a Kobo aura H20 (FW:3.12.0), it had run well with KSM07 + update_001 for months, but I got a problem after installing the update_02 & updat_03.

I followed the spoiler, copied both update_02 & updat_03 to .adds\kbmenu via usb; then disabled usb; then disconnected; then selected "install KSM update" in the menu and wait.
But after Kobo H20 rebooted, I found I can't enable usb any more!

Now, if I select "usb enable.sh", it shows: "USB support: disabled, USBNet support: disabled"; if I select "usb enable id like nickel.sh", it shows the same information.
Otherwise, I select "usbnet toggle.sh", it works and shows: "USNNet support: enabled"!

I've tried reboot it several times, but I got the same situation. I still can't make the usb enabled!


Would you please tell me how can I enable USB?
Thanks very much!

...

OK, I fixed it.

Usually, I put an SD card in my Kobo H2O, but I removed the SD card while updating KSM.
After I insert the SD card back into Kobo H2O, the usb can be enabled.

I tried it again: remove SD card, reboot H2O, USB enable does NOT work.
Put SD Card back, USB enable works!

I don't know why, but it seems interesting.

Anyway, thanks!

Thanks for your assistance, it's greatly appreciated.
After all the things i've tried, asked and did looks like finally i've made a script that does what i wanted it to do. It has some flaws (like if server has a dir present - it'll probably won't work but after all it's just a 'i'm lazy, i don't want to connect my USB' kind of script i think it's ok)
So, if somebody ever needs exact same thing i did - here's the listing

Spoiler:

#!/bin/sh

index=/tmp/index_$(date +%Y%m%d_%H%M%S)
pindex=/tmp/pindex_$(date +%Y%m%d_%H%M%S)
cindex=/tmp/cindex_$(date +%Y%m%d_%H%M%S)
theurl=http://192.168.1.10:1111
thedir=/mnt/onboard/.books/wgot_em
thetemp=/mnt/onboard/.books/wgot_em/tmp

if [ ! -d "$thedir" ]; then
mkdir $thedir
fi

mkdir $thetemp
wget -O $index $theurl

while read line ;do
echo $(sed -n "/href/ s/.*href=['\"]\([^'\"]*\)['\"].*/\1/gp" | grep -v '../') > $pindex
done < $index

sed -r -e 's/\s+/\n/g' $pindex > $cindex

while read line ;do
wget -O $thetemp/$line $theurl/$line
mv -f $thetemp/$line $thedir/$line
done < $cindex

rm $index
rm $pindex
rm $cindex
rm -rf $thetemp

Spoiler:

Here's an explanation of what this script does.
First, there's a bunch of variables.
$index is a raw index.html from web server.
$pindex - Prepared index - has only links instead of full html page.
$cindex is a Clear index.html, has \n's instead of spaces.
$theurl - web server's address and port
$thedir - is where books will be stored after all the things done
$thetemp - temp folder under $thedir. removed after script's job done
if block makes sure there's a $thedir.
Then it creates $thetemp and gets unprepared index from server.
After, while loop does extracting job, getting all the links from html, except "../".
sed replaces all the spaces with \n's
Another while loop gets all the files from server and moves them to $thedir rewriting any existing file in here.
And cleans the stuff, removing all the index files and the temp directory

Note: script is adapted to nginx 1.9.0 with autoindex enabled, all the books should be placed in /html (aka root) nginx directory. Provided as-is, not guaranteed to work ('cause i'm bad at scripting), but at least for me it does.

Thanks for all the help i got here

I am glad you found a solution! Thank you for sharing the script.

Indeed, very interesting. Possibly this is not related to the two updates. This strange behaviour might have been there already before. Anyway, I do not know why this is happening on your device. I usually do not use an external SD card and have no problem enabling usb. Can nickel connect to the pc if there is not cd card inserted?

Just tried connecting to PC in nickel, it doesn't show me the screen of connect to PC.
It tried connecting to PC with SD card & without SD card, neither works.

It seems I can't connect to PC in nickel at all.
But it doesn't matter, I can connect my device to PC in KSM.

I think this is serious. In this situation nickel will not process any books that you put anew to the reader. Maybe you do not use nickel anyway and therefore you do not care so much. But something is wrong with your device. Maybe you should factory reset it.

Do you have any other "irregular" software that runs after boot beside KSM?

If for some reason KSM does not work on Glo HD at all, wait until nickel (the original Kobo GUI) is started automatically after 20 seconds. Then connect via usb to your pc and delete the folder .adds.

I have a Glo HD. KSM installs fine, but when I go to process update 1 the geometry flips 90 degrees clockwise on the "tap&close" page and I cannot move forward from there.

Are you still on this page? If yes, force a power-off (press the power button for 20 seconds or even longer, you will not see any change on the screen) and then power on again. If KSM still not working, power-off and on again, wait until nickel is started automatically, connect via usb, rename .adds\kbmenu to .adds\_kbmenu in order to temporarily disable KSM.

Ya, I tried that stuff before I got your message. I had to pull the SD card and remove the kbmenu folder to get it working again. It just became a blank screen and would no longer boot nickle.
