COPS : Calibre OPDS PHP Server

[mariosipad]

I have recently updated my Synology (DS110j) to DSM 5.0-4482.

I read somewhere that user authentication should now work out of the box. I decided to give it a try. And success!!! It works.

There is no longer any need for:

LoadModule authn_file_module modules/mod_authn_file.so
LoadModule authn_dbm_module modules/mod_authn_dbm.so
LoadModule authn_anon_module modules/mod_authn_anon.so
LoadModule authn_dbd_module modules/mod_authn_dbd.so
LoadModule authz_groupfile_module modules/mod_authz_groupfile.so
LoadModule authz_user_module modules/mod_authz_user.so
LoadModule authz_dbm_module modules/mod_authz_dbm.so
LoadModule authz_owner_module modules/mod_authz_owner.so
LoadModule auth_digest_module modules/mod_auth_digest.so

.htaccess with:

<FilesMatch "\.php$">
AuthUserFile /path/to/.htpasswd
AuthGroupFile /dev/null
AuthName "User & password:"
AuthType Basic
Require valid-user
</FilesMatch>

worx!

[I did not test this on the synology package, I installed COPS from source.]

PS: I had some trouble editing the .htaccess file with vi. The last line of the file (</FilesMatch>) was not visible. I forgot to delete #. This caused a lot of and and once I figured this out.

@mariosipad

Great news ! And thanks you for upgrading

I may try also myself now that things seems almost good with DSM5.

I've added a empty line at the end of .htaccess it may help (will commit it shortly).

@tombo

About the kepub, it's true, I don't transform the epub to kepub like the Calibre plugin does so things may not work. I'll add a third value to the parameter to handle that case or fix the code in another way.

About the URL rewriting rule I really don't know what's wrong. I'll think about it.

Was there a problem with using .htaccess then ?
I remember us posting (June last year) about that here. Only my Kobo has problems with basic authentication, but it worked fine on other devices.

The problem appeared only with DSM5.

Hi Vlad,

Just installed and configured COPS on my Mac Mini which I use as a server. Running Calibre's built in web server really slows down the computer so I'm really glad to be able to use your great software. I particularly like the ability to email books to my Kindle right from a browser, it's a brilliant feature.

Is there any way to get the email button to show in the list of books, instead of just in the book detail view? Could I replace one of the book formats with it?

Also, I found that I'm unable to download books using Chrome on iOS. It works fine in Safari, and in desktop Chrome. Any ideas as to why that may be?

Indeed it could help. I'll check if it can be easily done.

That is extremely strange, do you use a password protected catalog ?

In my experience Safari is one of a few browsers in iOS that can download from COPS. I have tried Chrome and others but none of them could download from COPS (haven't tried pdf's only epub and mobi). However the Dolphin browser was able to download from COPS.

I think its not an issue of COPS, but a limitation with the iOS browsers I tried.

Good morning,
since a couple of days I get "503 - Service not available" whenever I try to access my calibre library. I am using COPS for quite some time and love it, but seemingly out of the blue it gives me the message above.
My webserver is lighttpd on a Raspberry Pi with wheezy (Debian), the calibre stuff resides on a Synology NAS. Up to now no issues.
My suspicion is an update of php5 a few days ago. After that (my best guess) I see this 503 message.
Php is not my cup of tea, so I am asking for suggestions how to pin down the problem. Can I switch on some sort of trace or stuff like that to get an idea what happens ?
I am pretty sure that there is no issue with access rights, since everything is rwxrwxrwx (it is intranet only, access from outside only via VPN tunnel). And a couple of days earlier everything worked smoothly.

Any help or suggestions are highly welcome.

Thanks in advance
Joshi

@Joshi

Do you get "503 - Service not available" only with cops (http://<ip-raspberry-pi>/cops) or also with other webites on your Raspberry Pi (http://<ip-raspberry-pi>)?

If not, you could try http://<ip-raspberry-pi>/cops/checkconfig.php

Have you restarted your webserver and/or your Raspberry Pi?
Run "apt-get update && apt-get upgrade" again.

Hi mariosipad,
thanks a lot for your quick reaction.
I get it only with cops. If I address http://<ip-address-raspberry-pi> then I see the standard greeting page of the lighttpd server.
Yes, I have restarted it. I do routinely a reboot every morning at 04:00

I will try apt-get update and upgrade again, but I doubt it will help.
Anyway, I'll try and report back.
Again, thank you for your help.
Cheers
Joshi

Hi mariosipad,
did apt-get update and upgrade, then a reboot - no change, still 503.

Cheers

[mariosipad]

what if you make this file:

<html>
<head>
<title>PHP Test</title>
</head>
<body>
<?php
phpinfo();
?>
</body>
</html>

and save it as test.php in the www (or html) directory of lighttpd.

Then http://<ip-raspberry-pi>/test.php

Is there any output?

[joshimosh]

mariosipad,
thank you for not giving up ;-)
Interestingly enough http://<ip-raspberry-pi>/test.php results in a 503 message as well.
Since I have another Raspi (which is set up rather similarily, but not identical to the other) with lighttpd as well, I get the same result.
Something seems to be wrong with the updated php5 - could that be ?
But it is odd that the same problem shows up on both Radpis. This would sort of exclude that one update due to some glitch went wrong. Same glitch at another time on another Raspi ? Pretty unlikely.
First thing tomorrow morning is to do a roll-back to the version before the update and see if the problem is not there (which is what I expect) - unless you have another idea ...

Thank you
Cheers
Joshi

[joshimosh]

So I did a roll-back to the previous version and 503 was gone - so my suspicion was correct.
Then I did apt-get update and upgrade and a bunch of new versions showed up, amongst them a few related to php5. I did the upgrade et voilà my "friend" 503 was back again.
Now I will ask my friend Google how to upgrade but exclude certain packets from the upgrade.
Sort of funny that no one else but me seems to be affected ...
Anyway, thanks again for your suggestions.
Have a nice one
Joshi

[joshimosh]

For the benefit of those who will encounter the same problem: reading the error logs helps a lot.
In my case it said: Permision denied /tmp/php5-fpm.sock

A look at it showed that the owner is root and access is rw-rw----, so lighttpd could not access it. Changing to rw-rw-rw- did the trick.
Now need to check why the hell the access right have changed after the upgrade - but this is not a topic for this thread.
Thanks to mariosipad for his input.
