A complete step by step how to for utorrent

cry_wolf · December 30, 2011

Hello every one,

I was really glad to see utorrent for linux, I am a big time utorrent fan. I've used it and it realy came up to my expectations.

I've written a complete step by step how to for installing utorrent on linux. With a complete and comprehensive config file and a easy to use start/stop script:

Your suggestions and comments are welcomed:)

Thanks Khizer,

i have a Centos 5.5 server with 32bit architecture which i need to operate remotely (through ssh).

I have some running websites there and want to install utorrent like www.example.com/utorrent.

is it possible? Little help will be appreciated.

meetanik · December 31, 2011

Hello Khizer,

I almost done all the steps but can't get the server started.

Utorrent Server..
/opt/utorrent/utserver: error while loading shared libraries: libssl.so.0.9.8: cannot open shared object file: No such file or           directory

Seems to be openssl have some problem, so i did this following.

yum list installed | grep ssl
mod_ssl.i386                          1:2.2.21-lxcenter.2              installed
openssl.i686                          0.9.8e-20.el5                    installed

after that 'yum install openssl openssl-devel'

Installed:
  openssl-devel.i386 0:0.9.8e-20.el5

Dependency Installed:
  e2fsprogs-devel.i386 0:1.39-33.el5        keyutils-libs-devel.i386 0:1.2-1.el5    krb5-devel.i386 0:1.6.1-63.el5_7
  libselinux-devel.i386 0:1.33.4-5.7.el5    libsepol-devel.i386 0:1.15.2-3.el5      zlib-devel.i386 0:1.2.3-4.el5

Dependency Updated:
  e2fsprogs.i386 0:1.39-33.el5        e2fsprogs-libs.i386 0:1.39-33.el5        krb5-libs.i386 0:1.6.1-63.el5_7

Complete!
-bash-3.2# yum list installed | grep ssl
mod_ssl.i386                          1:2.2.21-lxcenter.2              installed
openssl.i686                          0.9.8e-20.el5                    installed
openssl-devel.i386                    0.9.8e-20.el5                    installed

i tried this following also, but not succeeded.

ln -s /usr/lib/libssl.so.1.0.0 /usr/lib/libssl.so.0.9.8
ln -s /usr/lib/libcrypto.so.1.0.0 /usr/lib/libcrypto.so.0.9.8

Can't run the server. As you said before about the dependencies.

glibc
libgcc
openssl
krb5-libs
libcom_err
zlib
zlib-devel
keyutils-libs
libselinux

I'm not sure how to check them. Can you explain further?

meetanik · December 31, 2011

when i run this commands i get this

ln -s /usr/lib/libssl.so.1.0.0 /usr/lib/libssl.so.0.9.8
ln: creating symbolic link `/usr/lib/libssl.so.0.9.8' to `/usr/lib/libssl.so.1.0.0': File exists

cry_wolf · December 31, 2011

Can you show the output of the following commands:

updatedb
locate libssl.so
echo $PATH

meetanik · December 31, 2011

yes, why not.

-bash-3.2# updatedb
-bash: updatedb: command not found

-bash-3.2# locate libssl.so
-bash: locate: command not found

-bash-3.2# echo $PATH
/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/ usr/sbin:/usr/bin

cry_wolf · December 31, 2011

oh, you don't have "mlocate" installed. but that is not necessary. Try:

ls -l /usr/lib/libssl*

meetanik · December 31, 2011

-bash-3.2# ls -l /usr/lib/libssl*
-rw-r--r-- 1 root root 458752 Aug 14 03:57 /usr/lib/libssl.a

-bash-3.2# utsctl start

/opt/utorrent/utserver: error while loading shared libraries: libssl.so.0.9.8: cannot open shared object file: No such file or directory
-bash-3.2#

Not started yet.

btw, how to install it? yum mlocate?

meetanik · December 31, 2011

and there the text is colored in green, red and sky. if you want i can post the screenshot..

cry_wolf · December 31, 2011

I think the problem is that you have libssl in /lib instead of /usr/lib. So Try this:

First remove the bad soft links created earlier:

rm /usr/lib/libssl.so.0.9.8
rm /usr/lib/libcrypto.so.0.9.8

Then create the correct link

ln -s /lib/libssl.so.0.9.8e /lib/libssl.so.0.9.8
ln -s /lib/libcrypto.so.0.9.8e /lib/libcrypto.so.0.9.8

meetanik · December 31, 2011

cry_wolf · December 31, 2011

Finally the libssl and libcrypto problem is solved

Now it looks like you either don't have glibc installed or an older version.

Find out what version of glibc is installed:

rpm -q glibc

Try updating:

yum update glibc libgcc

meetanik · December 31, 2011

yes it is.

now this thing isn't updating. see this.

-bash-3.2# rpm -q glibc

meetanik · January 2, 2012

Hello Khizer, are you free there now?

cry_wolf · January 2, 2012

yeah, whats up?

meetanik · January 2, 2012

as you saw the server still isn't running..

cry_wolf · January 2, 2012

Well it turns out that you can not run utserver with glibc version less than 2.11. The last version of glibc for centos 5 was 2.5. So I recommend you to either use centos 6, or fedora/ubuntu. You also have the option to download and compile glibc-2.11 or greater, but that would be very un-necssary and risky.

meetanik · January 2, 2012

When i ran this command rpm -q glibc the version showed 'glibc-2.5-65.el5_7.1'. So it's seems i have 2.5 installed. But 'yum update glibc libgcc' returned

'0 packages excluded due to repository protections

Setting up Update Process

No Packages marked for Update'

I think there is some restriction to access glibc? I can't change my os as there is working websites hosted and i will loss a huge amount of data. Any idea to come over this issue?

And thanks a lot again, you helped me so much from the very beginning.

meetanik · January 2, 2012

is there is any way to upgrade to centos 6 without reinstalling the server and lossing any data?

Does yum update will work?

And how to compile 2.11 manually? What is the risk for doing so?

cry_wolf · January 2, 2012

A user facing the same problem, claims to have solve the problem:

http://forum.utorrent.com/viewtopic.php?pid=576708#p576708

meetanik · January 2, 2012

I think that not gonna help me. It was on debian while i'm in centos. Also i dont know where to copy the 2.11 files from. Can you tellme how to compile it in a different path so that utorrent server can only use it.

meetanik · January 2, 2012

you may want to look at this thread. http://forum.utorrent.com/viewtopic.php?pid=570716#p570716

everything was fine till '$ echo "CFLAGS += -march=i486 -mtune=i686 -O2 -pipe" > configparms'

but after it..

bash-3.2# make

Any suggestion?

centos docs don't cover this?

meetanik · January 2, 2012

can you post a simple tutorial about that?

I think this may answer your first and second question..
