When I execute the shell script to install it by typing ./azureus I get the following errors:

Azureus TERMINATED.

How should I go about it? I use Red Hat Enterprise Linux v4 [Gnome].
Thanks.

If you download Azureus fron Sourceforge, once you 'untar' the tarball, is all ready to go. In the folder you will find a file /tmp/azureus/azureus that's ready to run.

I've downloaded from sourceforge and 'untarred' by issuing the command
"tar xvjf Azureus_2.5.0.4_linux.tar.bz2"
A folder is created which contains:

azureus
Azureus.png
ChangeLog.txt
plugins
swt-about.html
Azureus2.jar
Azureus.torrent.png
License.txt
README.txt
swt.jar

No tmp directory.

I use gnome.

I'm using Suse 10.2; maybe that's why the difference. Seriously, I don't remember having to compile it. What does the README.txt says in your case? In my case, all I had to do was double click on the file 'azureus' and a message came up giving me the choice to 'Display'. 'Run in Terminal? or simply 'Run?. If you choose the latter Azureus shows up with it's Wizard.

This is my README.txt file:

REQUIREMENTS:
Azureus requires Sun Java 1.4.x or newer to run.
JRE 1.5 (5.0 series) is highly recommended.
http://java.sun.com

RUNNING:
1. Extract the contents of this .tar.bz2 file.
2. Change to the 'azureus' directory where the files were extracted.
3. Start Azureus by running the script named 'azureus'; ex. "./azureus"

NOTE:
If you have the Java JRE installed somewhere unusual (or not in your PATH),
use the JAVA_PROGRAM_DIR option in the script.

If you keep having troubles, I'd update to the latest Java. ( Link in the README file )

The Readme.txt file contains:

"REQUIREMENTS:

I have jre1.6.0_01 installed (verified from www.java.com/getjava) but when I issue the 'java -version' command it shows 1.4.2:

[oracle@ivory ~]$ java -version
java version "1.4.2"
gcj (GCC) 3.4.6 20060404 (Red Hat 3.4.6-8)
Copyright (C) 2006 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Run these in a terminal:

echo JRE_HOME=/path/to/jre6 >> /etc/profile
echo export JRE_HOME >> /etc/profile
source /etc/profile

Then cd to /path/to/azureus
and run
azureus

I did using su as it gave a permission denied error.
[root@ivory oracle]# echo JRE_HOME=/usr/java/jre1.6.0_01 >> /etc/profile
[root@ivory oracle]# echo export JRE_HOME >> /etc/profile
[root@ivory oracle]# source /etc/profile

Then I cd to /usr/java/jre1.6.0_01 but there is no azureus folder there
I checked in /usr/java/ too.

echo $PATH as root contains:
[root@ivory oracle]# echo $PATH
/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/oracle/bin

as a non-root user contains:
[oracle@ivory ~]$ echo $PATH
/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/oracle/bin


At the end of the /etc/profile it shows:

unset i
unset pathmunge
JRE_HOME=/path/to/jre6
export JRE_HOME
JRE_HOME=/usr/java/jre1.6.0_01
export JRE_HOME
JRE_HOME=/usr/java/jre1.6.0_01/
export JRE_HOME

Remember, I am a newbie as it states under my name on the left corner so please don't laugh!

How did you end up with three sets of those? One should be enough. From the looks of it, JRE was already there so you should remove the first pair (JRE_HOME=/path/... to export JRE_HOME just underneath). Remove the last pair as well so that only lines 3 and 4 remain.
Verify that jre really resides under in the java subdirectory of /usr. If not, the path will need to be adjusted.
Then run this command again:
source /etc/profile
And check by running java - version.

Of course it isn't, azureus is in a folder of its own, not in the java folder. You can run this command:
whereis azureus
and that should show where it was installed. You need to cd to the azureus folder. For example, it it was placed under /usr/local, you should:
cd /usr/local/azureus/
and then run:
azureus

now it is:

unset i
unset pathmunge
JRE_HOME=/usr/java/jre1.6.0_01/
export JRE_HOME

But even after I issued source /etc/profile and issue 'java -version', I still get as 1.4.2.
I had extracted in the directory /home/oracle/Desktop/Fireload/azureus.
And I issued the command azureus:

[oracle@ivory azureus]$ azureus
bash: azureus: command not found

If I try ./azureus I get the old huge list of errors which I've posted previously.

Looking over the error log, I'm struck by the presence of a charset exception. It makes me wonder whether it's not simply a local issue. Could it be that JRE does not support your language?

You should be able to set English like this:
$ LC_CTYPE=en_GB;LANG=en_GB;azureus

Looks like I'll be stuck here. Any other clients you prefer? I've already tried installing bittorrent and it says missing pythons and all. I've been through a maze while trying to installing it.

This appears to be excellent as well:

http://ktorrent.org/

I only hope you have better luck with it.

I suppose thats for KDE. I use gnome. Please tell me which other clients are good and easy to install

I'm afraid I'be been using Azureus and Ktorrent only so I can't really recommend on anything else. Deluge might be an option but it looks a lot more limited than the other two. Still, it's GTK based so if you need something to run nicely with Gnome, it may be worthwile looking into. Or perhaps torrentflux? It's described as "web-based, feature-rich bittorrent client" - but that's all I know about it.
