Unable to open secret.txt about muximux

[mescon]

Sounds real weird.
Are you absolutely positive that nginx is the user and nginx is the group?

chown -R nginx.nginx /usr/share/nginx/html/Muximux should be all there is.

Also - make sure you allow fopen in php.ini (remember to restart php-fpm after you changed it).

What should the permissions be on secret.txt? I feel like it should not be served out as /secret.txt on the web server for anyone to ask for. Maybe I need to update my nginx config to deny serving .txt files?

[mescon]

Permission should be readable by group/or the user that nginx is running as.
Basically, try to open /secret.txt and if it works, then you're good.

It should be served out as /secret.txt and no, do not deny serving .txt files.

On each page load, secret.txt is generated by muximux.php. When you close the site or otherwise navigate away from it, the secret.txt contents are re-generated, and as such is not longer valid.
Besides, you should have already secured / with HTTP Basic Auth.

If you can not open /secret.txt, then the application will not load. The ID generated is grabbed for use in the JavaScript by an AJAX-function.

[evanmj]

Thanks for the explanation. I do secure with Auth_Basic, and I thought secret.txt was static content, so if it is generated that is fine. Thanks!

So here are the permissions

Here is my php www.conf

Here is nginx running
http://i.imgur.com/oPNSXwq.png

I am able to open secret.txt in a browser (the one I created myself).

If you give more details about fopen I can try to resolve it but as far as I can tell that should only need the ww user (nginx) to have write access to the www-root folder.

the only thing I haven't been able to figure out is that parse_ini_file is not mentioned in my php.ini. If the default is on then there shouldn't be an issue unless it relies on the default config to set that. If that's the case could you please provide an example as I've not found one.

Cheers

The directory Muximux is installed in does not have write permissions. Please make sure your apache/nginx/IIS/lightHttpd user has write permissions to this folder

[Sup3rlativ3]

How can I help get this solved?

[mescon]

Would it be possible for me to see what you see via TeamViewer or any other means? This seems really weird.

[Sup3rlativ3]

sure. email me at [email protected]. Do you have a gpg or some other form of verification?

Edit: It's 1am here now so I may or may not be able to do this tonight. If not we can organise a time.

[Sup3rlativ3]

Help?

[mescon]

Sorry - work got in the way. Perhaps we could set a time for the weekend? I'm on Central European Time (CET).

[Sup3rlativ3]

I've not received an email time. I'll work around you. Thanks.

[mescon]

@Sup3rlativ3 Hey, are you able to get online on Gitter so that we can sort this out?

https://gitter.im/mescon/Muximux

[rmensing]

Possibly Solved.
Same problem on two issue reports and neither solved before closed.
The following solved the problem for me.

[Ubuntu 16.04, PHP7.0]
Make sure the parent directory you are serving out of has the correct permissions.
nginx owner www-data:www-data
php owner www-data:www-data
My root directory for muximux is /var/www/html/
All files in that directory and below are owned by www-data.

To fix the issue I had to also set the PARENT directory to the same owner:group:
sudo chown www-data:www-data /var/www/html

[ehvanr]

Came across this issue myself. Noticed OP was running it on the same system (CentOS 7). It was SELinux. You need to change the context of secret.txt to "httpd_sys_rw_content_t" as opposed to the default "httpd_sys_content_t"

Set the context:
semanage fcontext -a -t httpd_sys_rw_content_t /var/www/html/secret.txt

Then restore the existing context to the new context:
restorecon -v /var/www/html/secret.txt

[mescon]

Wow, great to know @evreichard, thanks for your help!
