Because rtorrent hangs on big files, and Transmission can be used with a web-UI

Help me build & setup Transmission

anandus 1191504229|%e %b %Y, %H:%M %Z|agohover

Hi,

i'm trying to install Transmission on the Mybook.
(If anybody thinks this is a bad idea, please reply)

Unfortunately I can't get it to work properly.

This is what I did:

su -
cd /opt/
wget http://download.m0k.org/transmission/files/transmission-0.82.tar.gz
tar -zxvf transmission-0.82.tar.gz
./configure --disable-gtk
make
make install

Unfortunately it won't built the daemon as it says it can't find 'libevent', even though there's a folder called 'libevent' in that directory.

I also want to use transmission.cgi, like here, although I don't know where to find a new version of that.

Mind you, I got the idea from http://www.nslu2-linux.org/wiki/Optware/Transmission

---

I'm a relative newbie in Linux. I sort of know what I'm doing here, but don't understand why it isn't building the daemon.

So any suggestions? :)

Well, I assume you need to compile and install the libevent library first. Look in http://monkey.org/~provos/libevent/

Kind regards.

Re: Help me build & setup Transmission

anandus 1191705156|%e %b %Y, %H:%M %Z|agohover

Thanks!

How silly of me to overlook that.

Anyway, I've configured, maked and make installd it (;)), but transmission still won't run.
It says it can't find library 'libevent'. I've rebooted, but that didn't matter.
Do I need to start libevent up somewhere, or change a config file somwhere?

Anybody any clues?

Thanks :)

utsiplu 1192465384|%e %b %Y, %H:%M %Z|agohover

Sorry anandus, I am a bit out of sync.
So if I understand well, you installed libevent and transmission alright but the "transmission" executable complains about a missing library "libevent", OK? When this happens, it means that the executable cannot find the library path - silly is it - and there are several possible solutions. Maybe start by exposing the problem by issuing a ldd /path to Transmission/transmission … or whatever the fullpath of transmission exec is; you should receive a list of library.so => /path to libraries/library.so.0 and one that doesn't match libevent.so.0 => not found
If you want to have a better explanation of what I am suggesting, http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html is a good lecture on the subject.

• solution 1. Do an export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path to libevent.so.0 - probably export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

Check again with ldd, libevent.so should be found and transmission be happy now. That trick is mainly for development purposes.

• solution 2. Do a backup of /etc/ld.so.cache - better safe than sorry. If you have installed libevent in /lib or /usr/lib, do a "ldconfig" as root; it will rebuild /etc/ld.so.cache. If libevent.so.0 is somewhere else, it is a bit more tricky. Either make a symbolic link in /lib to libevent.so.0 - very easy for a few missing libs - or add a text file /etc/ld.so.conf containing a line with the path to libevent.so.0 - probably /usr/local/lib, good solution is you intend to install many local libs. Do the ldconfig, test with ldd /path to Transmission/transmission. Another solution would be to configure, compile and install libevent in the trusted place (/usr/lib); a configure —prefix=/usr, make and make install will do the trick - dont forget to cleanup the extra occurence, this solution may lead to overwriting system with user's libs so be vey cautious.

• … and solution 3. Well it may be advisable to compile transmission as a static executable i.e. with libevent routines incorporated. Check with ./configure —help in transmission source if it is possible. It requires more memory; maybe not a good idea for such a tiny device.

Kind regards

That's exactly my problem, I don't have any time now, some visitors coming over, but I'll definitely try this tonight!

Thanks for the input, much appreciated!

Well, I had the same problem and someone else in this forum too.
This should fix your problem :

edit /etc/ld.so.conf (or create it if doesn't exist)
add a line to point to your library path (for example /usr/local/lib)
Exit editor, save

type ldconfig -v
At the end of the list, you should see a line showing libraries found.

Re: Help me build & setup Transmission

anandus 1192525029|%e %b %Y, %H:%M %Z|agohover

Excellent, that did the trick!
And so easy too! :)

Before I go on, I want to mention that once I've got this running, i'll add a proper page to this wiki how to set it up in a good fashion, and not in the slice&dice way I'm using now ;)

---

So, I've got the transmission-deamon running now. (Checked it with 'top')

FYI, I'm loosely following this page.

There are 3 pieces of software working on the torrents:

1. transmissiond. This is the actual workhorse that's downloading and uploading a torrent. If you run "ps" in a console you will see several of them working (if you have torrents running). Every time a torrent starts, one of these comes along and takes charge of it.
2. transmission_watchdog. This one runs periodically, usually every 30 minutes, and is in charge of moving torrents around the queues (from "queued" to "active" to "done").
3. transmission.cgi this is the actual web interface and is the thing you use to see your torrents and control them.

So, the first one is taken care of.
Now the transmission_watchdog.
Also from the page mentioned earlier in my post:

transmission_watchdog cares for queue processing and should be run every 30 minutes with cron. /opt/etc/crontab entry should look like:
# m h dom mon dow user command
*/30 * * * * admin nice transmission_watchdog

The only crontab-ish thing I could find was an empty file at /var/spool/cron/crontabs, is this the file where I should but aforementioned entry? For now I did that, dunno if it's good or bad.
I hope somebody can help me out in this respect.

And now for step 3, the web-interface. I've installed 'haserl', according to Martin hinner's pages, so cgi should be working, right?

Transmission.cgi is located in /opt/transmission.cgi

So, how can I access transmission.cgi through my browser? http://<IP-of-Mybook>/cgi-bin/transmission.cgi didn't work :P

---

Thanks for all the help!

Re: Help me build & setup Transmission

Zium 1192556410|%e %b %Y, %H:%M %Z|agohover

I'm using crontabs, i did by this way :

Log into root
Copy /etc/crontabs/root to /etc/crontabs/user (where user is your username)
edit /etc/crontabs/user, remove the existing cron (writing time)
add what you want…

The crontab works for the given user.

Re: Help me build & setup Transmission

anandus 1192560605|%e %b %Y, %H:%M %Z|agohover

Thanks!
So that's step 2 done!

We're almost there \o/

Now how can I get to transmission.cgi in my webbrowser?
Do I need to put it in some sort of cgi-bin or something?

edit:
There is a /var/webif/cgi-bin
Do I need to put transmission.cgi in there? Or do I need to enable cgi somewhere?

edit:
Okay, I've found the www directory in /usr/www/ this is the webinterface-area, right?
I've created a cgi-bin folder there and put transmission.cgi there.
But if I go to http://<IP-of-Mybook>/cgi-bin/transmission.cgi I get a 404
And I think I've got haserl running (that'sthe cgi-interpreter, right?)

So… what am I missing? :)

I'm not using webif; however the default administrator interface is fed by lighttpd (google it.)

The web interface is located under /usr/www/lib
This information is found under /etc/lighttpd/lighttpd.conf. The first line reads: Server.document-root = "/usr/www/lib/"

Trying this on my My Book World myself but getting stuck at ./configure —disable-gtk. I get the following:

configure: error: Package requirements (openssl >= 0.9.8) were not met:

No Package 'openssl' found

Already have openSSL compiled and installed (ver 0.9.8e — which I did when I installed rtorrent previously).

Would appreciate any help.

Thanks!

utkuozyurek 1196207662|%e %b %Y, %H:%M %Z|agohover

you should add this path before configure

export PKG_CONFIG_PATH=/usr/local/ssl/lib/pkgconfig/

YEA BABY YEA I GOT TRANSMISSION WORKING WITH CLUTCH WEBUI and its perfect, posting instructions soon :p

Re: Help me build & setup Transmission

kevku 1196433663|%e %b %Y, %H:%M %Z|agohover

ok it time to get a decent torrent client working so i got transmission-deamon & cluth and i hope it works
first you should recompile your php with option —enable-sockets if you have installed php before, if u havn't just compile it then :p just follow the instructions in php install thread and add —enable-sockets when u configure.
i used: php5.2.5
./configure —without-iconv —without-pear —enable-fastcgi —enable-discard-path —enable-force-cgi-redirect —without-mysql —enable-sockets

openSSL
wget http://www.openssl.org/source/openssl-0.9.8g.tar.gz
tar -xvf openssl-0.9.8g.tar.gz
cd openssl-0.9.8g/
./configure
make && make install

pkg-config
wget http://pkgconfig.freedesktop.org/releases/pkg-config-0.22.tar.gz
tar -xvf pkg-config-0.22.tar.gz
cd pkg-config-0.22/
./configure
make && make install

!!!!export PKG_CONFIG_PATH=/usr/local/ssl/lib/pkgconfig/!!!!

Transmission
get the latest version (wget http://download.m0k.org/transmission/files/transmission-0.94.tar.bz2)
tar -xvf transmission-0.94.tar.bz2
cd transmission-0.94
./configure —disable-gtk
make && make install

Clutch #note i used svn version from svn co http://svn.recurser.com/transmission/trunk webgui
cd /to/your/web/directory/
wget http://clutchbt.com/Files/Clutch-0.1.tar.gz
tar -xvf Clutch-0.1.tar.gz

Edit the remote/data/socket.txt file in your WebUI folder, making sure it points to the location of your transmission-daemon socket file
(start transmission with transmission-deamon -s /path to your/socket file/)
Make sure the remote/data/ folder and it's contents are readable and writable by the web server (your prefs will be stored here).
Make sure the folder you intend to download to is readable and writable by the web server.

now u shoud have all working, when u have some strage errors with clutch try :
http://your.domain/transmission/remote/?action=requestSettings&param=0&filter=all&sort_method=queue_order&sort_direction=ascending&search=
(where http://your.domain/transmission/ is where you've installed clutch) and see if it returns any errors.

I've got Transmission installed succesfully, but do not know how to proceed.

This is what is listed in my /usr/local/bin/ directory :

transmission-cli
transmission-daemon
transmission-proxy

How do I start Transmission, where is the .conf located and how does the webui work ?
Do I need to make a directory for Transmission to watch if there are new torrents to be downloaded ?

Best regards,
Bart

Re: Help me build & setup Transmission

kevku 1196535652|%e %b %Y, %H:%M %Z|agohover

YOU NEED TO HAVE PHP INSTALLED!!!

you start transmission with "transmission-daemon -s /path/to/socket" where the path is what you choose in socket.txt file You can add torrents and change prefs from the webui
EXAMPLE:
my web server root dir is /shares/internal/PUBLIC/http-server #YOURS CAN BE DIFFERENT!!!! CHECK LIGHTTPD.CONF
so i cd /shares/internal/PUBLIC/http-server
wget http://clutchbt.com/Files/Clutch-0.1.tar.gz
tar -xvf Clutch-0.1.tar.gz
cd Clutch
now edit the socket path
nano remote/data/socket.txt
i start transmission with "transmission-daemon -s /shares/internal/PUBLIC/http-server/socket"
so in socket.txt I should read
/shares/internal/PUBLIC/http-server/socket
now save it
cd ..
chmod -R 777 Clutch/
now go to http://ip.of.your.mybook/Clutch and start downloading

also u can read http://trac.recurser.com/transmission/wiki/GettingStarted#InstallationLinux

kevku 1196582806|%e %b %Y, %H:%M %Z|agohover

well i havn't tried that but i think you prob have to install php, but not mysql, so it only takes about 3-4 hours.

teros 1196592591|%e %b %Y, %H:%M %Z|agohover

hey all just a bit of warning i had the same issue with openssl were when performing a ./configure stops and says cant find openssl you'll need to do the export PKG_CONFIG_PATH=/usr/local/ssl/lib/pkgconfig/ works after that.

Got a simple question for everyone is it possible to have transmission start by default with the system i.e. start from init.d or something? only asking as will prefer to use mybok to do all torrent dl's and leave all day.

Re: Help me build & setup Transmission

kevku 1196697394|%e %b %Y, %H:%M %Z|agohover

ok if you want to start transmission at boot time then

cd /etc/init.d/

nano S88transmission
transmission-daemon -s /path/to/your/socket/file
save

nano K88transmission
killall transmission-daemon
save

chmod a+x *88transmission

!!
if this don't work and u get permissions error then add
chmod -R 777 /path/to/your/socket/file
to S88transmission

NOTE: i havn't tested this coz i have mybook running 24/7

Re: Help me build & setup Transmission

piotrus 1197051428|%e %b %Y, %H:%M %Z|agohover

So what files are in

/shares/internal/PUBLIC/http-server/socket

Followed the tutorial, didnt have this directory and created it. What files should go in this directory ?

Re: Help me build & setup Transmission

teros 1196595873|%e %b %Y, %H:%M %Z|agohover

kevku,

Basically copying or attempting to copy your config with the websever directory sounds a lot more structred than having crap everywhere attempting to edit the LIGHTTPD.CONF must admit never played with it so am attempting to do a soft link would the below work?

ln -s /shares/internal/PUBLIC/http-server/Clutch

have everything configured except this part i.e. no webserving for the gui web front end if not could you point me to which flag in LIGHTTPD should change

changed Server.document-root = "/usr/www/lib/" to /shares/internal/PUBLIC/http-server still not working. any help would be muchly appreciated.

kevku, anandus,

I've succesfully installed PHP following this guide : http://chayden.dyndns.info/info/mybookworld:php.

Testing it with : http://<MyBook-IP>/test/test.php gave me a bunch of information about the PHP installation.

So far so good …

Installed transmission this way :

1. wget http://download.m0k.org/transmission/files/transmission-0.94.tar.bz2
2. tar jxvf transmission-0.94.tar.bz2
3. cd transmission-0.94.tar.bz2
4. ./configure —disable-gtk
5. make
6. make install

Installed Clutch this way :

1. cd /shares/internal/PUBLIC/
2. mkdir http-server
3. cd /shares/internal/PUBLIC/http-server/
4. wget http://clutchbt.com/Files/Clutch-0.1.tar.gz
5. tar -xvf Clutch-0.1.tar.gz
6. mv Clutch-0.1 Clutch
7. chmod -R 777 Clutch/

Now I edit the socket path, and point it to my server root dir …

1. cd Clutch
2. nano remote/data/socket.txt

put following line into socket.txt : /shares/internal/PUBLIC/http-server/socket

I started transmission with "transmission-daemon -s /shares/internal/PUBLIC/http-server/socket"

Is there a way I can check if transmission is running, I tried with 'ps -A', but did not see it …

When I browsed to "http://mybookworld/Clutch" in firefox, I got following error :

Help me, I'm so close to the working solution …

Best regards,

Bart.

Re: Help me build & setup Transmission

Try:
chown www-data:www-data /shares/internal/PUBLIC/http-server/socket
Replace www-data with the user/group of the user under which lighttpd is running.

I am not sure if this will work when the daemon is stopped and started again (no idea if the permissions on the file are replaced when this happens).

Re: Help me build & setup Transmission

kevku 1196694804|%e %b %Y, %H:%M %Z|agohover

Bartus: are you sure you added - -enable-sockets when configuring php? you can check that from phpinfo

Teros: what browser are you using?

i can see if my deamon is running with command ps aux
$ ps aux | grep transmission-daemon
scaleo 2721 0.1 16.1 8364 4852 ? S Dec01 2:57 transmission-daemon -s /shares/internal/PUBLIC/http-server/Clutch/socket

TIP: don't start transmission with root user

ok u can get the latest svn version here what i use this is slightly better but not dramatically
http://www.hot.ee/mckevin/Clutch-0.1%2bsvn282.tar.gz

You know it is possible to get it working:

I did not add -enable-sockets when building PHP. I'll start it right now.

Do I have to rebuild Transmission as well ?

If I start daemon not from root, but other user I get following errror :

Aborted

im not sure but i guess that the other user don't have write permissions to the directory of your socket file

I reached to point where I as root user installed PHP, Transmission and Clutch.

Testing PHP with : http://<MyBook-IP>/test/test.php gave me a bunch of information about the PHP installation, so that part works.

What is to be done next, please explain step by step.

Should I continue the next steps as logged in as root user, or as another user ?

i did everything with root user exept i started transmission woth non root i have no idea why just a tweak. if you run it as root you have to change permissions to 777 of the socket file

Re: Help me build & setup Transmission

ok will try when back home to start transmission as a non root user. Would anyone be able to tell me how to get this loaded when the mybook starts up? do not wanna have to remember each time to load the thing up. And using firefox beta 3 as the browser.
