Fun with /www/user :)

[redhat27]

We all know that you can see the syslog from the web UI. However if you have relocated syslog somewhere else (or even if you haven't), here is an alternate way.

Symlinks from /tmp/syslog.log will still work, but if you use some non-standard logging, just change the DEFAULT_LOG to your log that you'd like to see on the browser

Run the script, and it creates a symlink from your /www/user directory to point to your syslog.log or any log defined on the DEFAULT_LOG.
Note that this change is not permanent (will not survive router boot, as /www/user resides on tmpfs)

 

[redhat27]

Here's another one: Say you want to publish a directory listing of any directory/mount that is accessible on your router. You can then use this script to do so.

Save the script to /jffs/scripts, chmod +x it and then run it with the directory you's want to list on the browser: Say you name the script html-dir.sh, then

/jffs/scripts/html-dir.sh /mnt/NAS/public
/jffs/scripts/html-dir.sh /jffs
/jffs/scripts/html-dir.sh /jffs/scripts
/jffs/scripts/html-dir.sh /opt/var/log

Could be possible ways of calling the script. Those directories are just examples, of course.

What the script does is create a html file in /www/user with the last directory in the tree specified, for example specifying /jffs/scripts as the parameter would create /www/user/scripts.html

Now, the router's built-in webserver is quite limited in what it can serve up, so I've also included a "nag" text to install lighttpd if you do not already have it installed and running.

If you do have lighttpd, it would chose to create the directory listing there and the files will appear as links, it would also create a symlink to the hosting directory location from the document-root of lighttpd. It will list out what it created and also spit out a handy rm -f command to undo the changes it did. Note that lighttpd also supports directory browsing, but you'd need to make some additional changes in order to make that happen (wont be supported out of the box) but using the script will make that happen without enabling any of those settings.

Of course, if you choose to go the lighttpd route, you can also port forward your lighttpd server port so that you can also access the files from outside your local network.

AND goes without saying, if you are exposing your files (especially with the port forward), I'd assume you know the implications of having your files exposed to the world

Two thumbs up! I like it.

 

[redhat27]

Uploaded a second script to display the directory and all subdirectory listing of any directory specified.
Description on post #2

 

[redhat27]

Both scripts should now display the final url string correctly, even if you have your router's httpd or httpds running on non-standard ports (for example httpds running on 8443)

No change in the html generation code.

Thanks @redhat27, I had some time to try the script. I installed lighttpd first, then ran the script. When I went to the webpage link, I got the message:

This page would work so much better if you had lighttpd installed and running. If you have entware, you can install it with opkg install lighttpd

It was my understanding I did not need to do any other configuration with lighttpd. Please let me know. Thank you!

 

[redhat27]

I suspect the lighttpd is not running, even though it is installed. Can you post:

ps | grep [l]ighttpd

If you get no output, it means its not running and the page you saw was served by the routers builtin webserver.

If it is not running, you can first try to manually start it with

/opt/etc/init.d/S80lighttpd start

Did you just install lighttpd? If that is the case, it would probably need a reboot. It should autostart everytime your router boots.
If you had lighttpd from before, it would be worth checking whether /opt/etc/init.d/S80lighttpd has the execute flag on

It was not started. I followed the instructions on this link https://www.hqt.ro/lighttpd-web-server-with-php-support-through-entware-ng/, steps 1 thru 6 to get lighttpd working. I now see links on the file names on the webpage. I get the option to save, save as or cancel when I click on them. Would be nice if the contents would display in a new browser tab. Maybe there is an option for that one. More reading..

I will need to reboot after wife 1.0 is done surfing the web to see if lighttpd starts up automatically. If not, I will add the following to services-start per this old thread: https://www.snbforums.com/threads/t...server-with-php-support-through-entware.9310/

sleep 10
/opt/etc/init.d/S80lighttpd restart

Thanks again for your very kewl and helpful scripts! I am grateful!

 

[redhat27]

@Xentrk All you need to do after the lighttpd install is just to start it with:

/opt/etc/init.d/S80lighttpd start

OR reboot your router.
Nothing else is needed, no PHP or other added installs.

Note that the script will also work without lighttpd, only files will not display as links. That's the fun with /www/user part

The options that you see on clicking the files (with lighttpd running) are totally dependent on your browser: Scripts and other files without extension may offer to download, while pictures and text files may open in the browser. You can almost always right click and save the files. More read on MIME types here

after wife 1.0 is done surfing the web

LOL I hope you never need to upgrade

Thanks again for your very kewl and helpful scripts! I am grateful!

Thank you for your kind words

 

[Xentrk]

All is good @redhat27! As you said, each browser has different behavior with the file name links on the browser web page.

1. Edge - gives option to save, save as, or cancel
2. Chrome - clicking on the link opens up contents in new window. Right click gives the same options as above and more
3. Firefox - clicking on the link opens up a window with options to open with preferred app (e.g. wordpad) or save file. Right click gives even more options.

 

[redhat27]

Very minor formatting changes on html-dir.sh uploaded on github. It will put a line break after each directory, which I think looks better. I will not be making any further changes to this simple script.

@Cat Thank you for the diagnostic output. Can you edit your /opt/etc/init.d/S80lighttpd and make sure there are no "-D" parameter in ARGS= line? Also redownload the script from my github. I made a change to grep just the lighttpd process, and not the monitor and arpping

 

[Cat]

There is not "-D" in S80lighttpd created after lighttpd installation. I didn't touch it.
To confirm it, I tried to remove and install lighttpd pkg again.

I am a linux novice. and then.. I can supply only detailed output info.
I can't understand most of linux scripts, and don't know what's going on.

I don't really need the functionality of this script, not in a hurry. you don't need to hurry for me. Just as you contribute to someone, I also want to contribute.
