Is it possible to write to /www ?

[yelo3]

I need to place a file in /www to let me configure an SSL certificate using letsencrypt.

How can I write to that folder? It says read only filesystem.
I need just to place a temporary file

You should be able to achieve the same result as mentioned here http://www.snbforums.com/threads/personalizing-gui-appearance-solved.29770/#post-230906

Unfortunately that didn't help.
Since I needed to create a full path named /.well-known/acme-challange/SFGWSo-DPDQ69zPARDVATAfOUVMbEQqtSh2zaOQZqNk I created

/tmp/www/.well-known/acme-challange/SFGWSo-DPDQ69zPARDVATAfOUVMbEQqtSh2zaOQZqNk

then run the command

mount -o bind /tmp/www /www
service restart_httpd

If I request the file I get a 404

The above will only work to replace a file that already exists in /www. If you want to add a new file, just copy the file to the

/tmp/var/wwwext

directory

Thanks for your help.
I've just created a new file in /tmp/var/www

echo hello > /tmp/var/wwwext/hello

But that doesn't seem to be available when browsing http://192.168.100.1/hello
I get a red/rose screen with the message
404 Not Found
File not found.

Any idea?

Same here with practically stock john's fork (AP mode with entware-ng).

Sorry, my fault....that's what happens when you dash off a quick response from memory

Two other things you need to know....

- to access the file, you need to access it by http://192.168.100.1/user/filename
- it only recognizes certain file types (such as would be used by a webserver)....in this test case, try hello.html as your filename. I also know it recognizes .png (I used to use this to provide custom icons for my library sections in Plex Roku Classic)

 

[yelo3]

No I can't, the complete path needs to be /.well-known/acme-challange/XXXXXX
I don't this I can do this...

Do you know any other free SSL certificate providers?

 

[gffmac]

Just thinking aloud but if you were to build the firmware could you incorporate the file/folder into /www then you would be able to remap it with
mount -o bind if you needed to change it?

 

[yelo3]

Well, I prefer finding another solution, but thanks for the suggestion

 

[RMerlin]

Basically:

Copy the /www content to a USB disk.

cp -a /www /mnt/sda1/newwww

Mount bind it

mount -o bind /mnt/sda1/newwww /www

Restart HTTPD.

service restart_httpd

That will make httpd use the files on the USB disk instead of the read-only flash. Once you are done with the validation process, you can just reboot the router to revert the change.

However if you need a permanent file added, you will have to build your own firmware, or deal with having to recreate your local www copy every time you upgrade to a new firmware.

 

[yelo3]

That's what I've tried, (well I created the new folder to /tmp/www instead on the usb disk) but it doesn't work, I get 404.
Is there any guide to configure a free HTTPS certificate in asuswrt? That's what I'm trying to do.

 

[john9527]

Ahh....it should be possible to create a script to add an external certificate. I can't work on it right now, but here's a link to the relevant code that creates the self-generated cert for https.....

if you get a 404 then you didn't properly copy the files, or didn't restart the web server the way I specified. Make sure they didn't end up in /tmp/www/www/ .

Hi, been trying to add a simple file the the router, so I can perform periodic speed tests of my network (from a remote PRTG server). Adding a file to wwwext works, but I need to be logged in to the router to see its contents, Is there a way I can add a file to the router so that I can see it without logging in? I have an N66U and an AC68U to choose from (both on 380.62_1)
If that file would survive a reboot even better...
Thanks!

Why not run something like iperf?

 

[Martin Fishkov]

because while iperf is nice as a user initiated tool, the integrated http probe of prtg is automated, giving me an overview of my network performance over time:
this graph uses /images/New_ui/networkmap/client-list.svg (the largest file I could fins in /www
It seems my network isn't as stable as I thought

 

[RMerlin]

Unauthenticated files need to be defined inside the httpd code, so no, AFAIK it's not possible without recompiling your own firmware.

 

[Martin Fishkov]

Thanks for the replies! Guess I'll have to let go of unauthenticated files for now. Last one then: How can I persistent over reboot write to wwwext? I created a wwwext folder in /jffs/, but that is obviously not enough.. (Hope this is not a case of rtfm, cause I did...)

 

[RMerlin]

Create a services-start script to copy the content from the /jffs/ folder to the /tmp one.
