This WebPortal mod already does that local network hack (refered to as intranet wifi in posts above), but it's still set to the old URL.

You can edit it yourself, add www.kobo.com to vhosts.conf and put that buildinfo.xml file into the webportal dir next to ncsi.txt that was used before.

If they're not checking anything else, the same trick should still work. (Change of vhosts.conf might require a reboot.)

I don't remember if the previous test was looking at the content returned or just that something was. The new test does appear to be checking the contents. But, it looks to be just checking that it starts properly.

It would be a problem if they checked HTTP response headers or something. Or if they use HTTPS instead of regular HTTP and expect a valid certificate. At some point you just have to patch.

Hello i installation webportal on a kobo H20 for make a wifi dysplay for marine application openplotter if i want to see a web page on intranet créatif with m'y raspberry pi node red serveur i have blank page do you know if it s possible to make this Can you hello me thinks a lot

[reexe]

I tried running on the latest firmware version of Kobo Aura second gen, the script starts but i could not get anything to show on http://webportal/

Uninstallation worked as intended.
Will maybe try again later and then instead of going to http://webportal/ i will try 127.0.0.1, did not try that (not shure if its suposed to work that way).

[reexe]

On what firmware version is this suposed to work? (specifically for Kobo Aura second gen)

[frostschutz]

It still works on my Aura H2O running 4.8 firmware. It should work in both older and newer firmwares.

However, it is a very old mod ( ported over from my iriver Story HD which I haven't used in ages ).

It does not have some of the resiliency of my other mods, for example, when booting, it blindly waits 10 seconds for /mnt/onboard to appear, otherwise it fails.

But if that was your problem then uninstallation would not have worked either.

[reexe]

I'm using KFMon, maybe that is conflicting somehow?
If I wanted to start the service manually either by typing the commands or using a script with KFMon, what would I need to do?
I am guessing that there is a file that routes the service to http://webportal would it be possible to just access it on localhost?

[reexe]

BTW, is it possible to store cookies in the browser? All cookies I write are lost if I restart the browser

well, if there was another mod that ran a webserver on port 80, that would conflict (but you'd know cause you'd get a reply of that other webserver then, yes?). unfortunately there
currently is no setting to make webportal run on a different port instead.

I am guessing that there is a file that routes the service to http://webportal would it be possible to just access it on localhost?

webportal creates an entry in /etc/hosts file. it maybe you need another reboot for that to be effective ( if you were too quick to start the webbrowser after installing the boot, perhaps )

you can just use http://127.0.0.1 (on the kobo) or http//ip.of.the.kobo (as shown in settings) although you'll have to edit .addons/webportal/httpd.conf to allow http access over wifi/LAN and reboot ...

maybe not

it's already lucky it supports them in session

it does not support a lot of things, some time ago there was a navigation app that used local storage and... yeah that didn't really work either.

So i installed it like u said and its working on my kobo, but how do i exactly get it to work on my pc? i want to try to upload books from the filemanager. this is my current httpd.conf file, idk if i should change it or if i need to change other files?

# busybox httpd.conf
# Documentation: http://git.busybox.net/busybox/tree/networking/httpd.c

# webportal home (you may use a different location for customizations)
H:/mnt/onboard/.addons/webportal

# allow localhost (the Kobo browser)
A:127.0.0.0/8

# allow LAN (to access from PC - only enable in networks you trust)
A:10.0.0.0/8
A:172.16.0.0/12
A:192.168.0.0/24

Hi, I have successfully installed it, but the intranet WiFi is not working. I have already uncommented a line in .webportal/vhosts.conf, but nothing has changed. Am I doing something wrong, or is it no longer functional?

***
I guess frostschutz is no longer supporting it. I did manage to get uploads working if it is of help to anyone.

Uploads gave me a "seg error" so I tried rebuilding httpd_preload.so and multipart_pipe in /usr/local/WebPortal/ .

On your kobo, replace the httpd_preload.so multipart_pipe and in /usr/local/WebPortal/ with the above versions.

Edit /mnt/onboard/.addons/webportal/httpd.conf to allow access to your cellphone, e.g.:
# allow LAN (to access from PC - only enable in networks you trust)
A:192.168.43.1/24

If that doesn't work, try commenting out the line (insecure):
# disallow everyone else
# D:*

(Have to restart the server,and wait a few seconds.)

From a ssh shelll to the kobo run:

# LD_PRELOAD="/usr/local/WebPortal/httpd_preload.so" httpd -f -c /mnt/onboard/.addons/w
ebportal/httpd.conf

From your cellphone, browse to the kobo webportal, e.g. http://192.168.43.5/

Downloads (by clicking on the kobo file) and Uploads (by browsing to the cellphone file) should work from the File Manager.


Append a nice gif animation to the welcome page:

$ nano -l /mnt/onboard/.addons/webportal/index.html

...
  <p><img SRC="sample.gif" ALT="sample"></p>
...

Copy a gif named sample.gif to /mnt/onboard/.addons/webportal/

A gif animation appears on the welcome page:

I commented out /etc/udev/rules.d/webportal.rules
# KERNEL=="loop0", RUN+="/usr/local/WebPortal/webportal.sh"
because it isn't guaranteed to start at boot, and may not even be secure to always start anyway, if you are using relaxed access rules like in httpd.conf above.

So I just made a NickelMenu entry like:

menu_item :main :WebPortal :cmd_spawn :quiet:/usr/local/WebPortal/webportal.sh
chain_success :dbg_toast :Started WebPortal
chain_failure :dbg_toast :Error

menu_item :main :Stop WebPortal :cmd_spawn :quiet:usr/bin/pkill httpd && /bin/rm -R /tmp/WebPortal/ && /bin/rm /tmp/webportal_hosts
chain_success :dbg_toast :Stopped WebPortal
chain_failure :dbg_toast :Error

(You have to wait a few seconds for it to start.)

* To run the portal directly from NickelMenu you can add this entry:

menu_item :main :Run WebPortal :nickel_browser :modal :http://webportal/

(As the README states, it "won't work if no wifi network is available, since the Kobo refuses to start the webbrowser".
However, if just WiFi is on. without even connecting to a hotspot, elinks in an fbpad terminal will still run WebPortal - just have to hit Ctrl-R on the fbkeyboard/oskansi keyboard to refresh the note.)


***

A few mods...

Set permissions:

$ nano /mnt/onboard/.addons/webportal/httpd.conf

...
# allow USB and cell connection
A:192.168.2.1
A:192.168.43.

# disallow everyone else
D:*
...

Remove 10-second delay if you decide to start only from NickelMenu:

$ nano -l /usr/local/WebPortal/webportal.sh

...
 13 # sleep 10
...

Correct mobileread link and add link to a gif:

$ nano /mnt/onboard/.addons/webportal/index.html
