ruTorrent <--> rTorrent, UNIX socket

[saroos1]

I'm trying to use a UNIX socket for communication between rTorrent and ruTorrent, rather than a TCP port. To be clear, it currently works using these config values:

Code: (.rtorrent.rc)
scgi_port = 127.0.0.1:5000
Code: (ruTorrent config.php)
$scgi_port = 5000;
$scgi_host = "127.0.0.1";

I am running nginx with php5-fpm, and my nginx site has this block:
Code:
location ~ \.php$ {
try_files $uri =404;

fastcgi_pass php5-fpm-sock;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_intercept_errors on;
fastcgi_param HTTPS on;
}
Then I have a file /etc/nginx/conf.d/php-sock.conf:
Code:
upstream php5-fpm-sock {
server unix:/var/run/php5-fpm.soc;
}
My understanding is that this passes any php files through to php-fpm using FastCGI. Under my web root is a rutorrent directory, and I have an nginx location block used to set up basic HTTP auth - this seems to work fine. I've seen a lot of talk about rpc plugin, etc. and I have not configured any of these to my knowledge, but in my nginx log file I see listed POST /rutorrent/plugins/httprpc.

Anyway, to try a unix socket I've set it up like this:

.rtorrent.rc:
Code:
scgi_local = /var/run/rtorrent/rtorrent-scgi.soc
ruTorrent config.php:
Code:
$scgi_port = 0;
$scgi_host = "unix:///var/run/rtorrent/rtorrent-scgi.soc";
But rtorrent gives the usual message 'No connection to rtorrent, check scgi_port and scgi_host' etc. I checked that rtorrent had created the socket and then tried adjusting the permissions on it and the /var/run/rtorrent directory but the error persisted. Even setting rwx for everyone did not work.

So why can't rutorrent find the socket to communicate with rtorrent? Like I said, works fine using a port.

Thanks in advance.

hello

me too i search for use ruTorrent <--> rTorrent, UNIX socket !

I've found a few other threads with the same problem, but none of them managed to help me at all

 

[lisas4567]

may be you will have more chance http://stackoverflow.com/ I'll go on this site ^^ sorry for my bad english

 

[saroos1]

Maybe serverfault would be a better fit for our question than stackoverflow - it's not really a programming question.

edit: progress! if I create the socket as /tmp/rpc.socket and make it readable, writable and executable by anyone then it works. I don't want to do this for obvious reasons

The default permissions are rwxrwxr-x which don't work. Adding www-data and rtorrent to the same group, and then making that group the owner of the file doesn't work. HOWEVER making www-data the owner (with the default permissions) of the file works. So what gives? I don't really want the socket to reside here with permissions that could potentially make rtorrent vulnerable.

can you show me your complete config files

reason: I want to check something and compare

// For example, if Webserver and rtorrent users are in the same group then the value may be 0770.

$tempDirectory = null; // Temp directory. Absolute path with trail slash. If null, then autodetect will be used.
Those are the working setups - the socket code is commented out.

ok I see we have the same thing I'll watch them on another forum and if I find the solution I'll post the answer here

schedule = scgi_permission,0,0,"execute.nothrow=chmod,0770,/…/.scgi_local"

And possibly a similar chgrp to set it to a shared group.

 

[saroos1]

This changes the permissions successfully, but I can't get it to change the group. Changing the group manually afterwards doesn't make rutorrent work.

Not sure why the schedule command is being used here? Either way, I tried making something similar up:
Code:
schedule = scgi_group,0,0,"execute.nothrow=chgrp,rtorrent-nginx,/home/rtorrent/scgi.socket"
but I have no documentation so no idea how to structure that. Likewise, I tried this:
Code:
execute = chmod,0770,/home/rtorrent/scgi.socket
execute = chgrp,rtorrent-nginx,/home/rtorrent/scgi.socketThe chmod worked but the chgrp did not. Opening a bash shell as the rtorrent user and typing:
Code:
chgrp rtorrent-nginx /home/rtorrent/scgi.socketChanges the group but, as I said above, this doesn't fix rutorrent.
