Torrentflux and RAR?

OK I have seen a few topics now about rar'ing files and so on but I'm just stuck.

I would like to rar and unrar. (I would like to pack multiple files into rar aswell as single files...)

I tried to install this

Code:

---

But when I click on the rar button all I get is a blank page :<

Any help or script would be very much appreciated :>

I'm running a Lunix server.

Ok any help on rar'ing I would be happy with :> I just have no idea lol.

Well if you have SSH acces you just need to do the following:
Firstly install rar and unrar

Code:

---

# For Debian based ones like Ubuntu
apt-get install rar unrar
# For Gentoo and Portage using systems
emerge -av rar unrar
# The Manual Method
wget http://www.rarlab.com/rar/rarlinux-3.7.1.tar.gz
tar xvf rarlinux-3.7.1.tar.gz
cd rar
cp rar unrar /usr/bin/

---

Then you just use it like this to RAR stuff up:

Code:

---

# Example were compressing the folder 'lawl' into pieces of 50MB each with max compression
rar a -r -m5 -v50m /home/melon/lawl/

---

And to unrar:

Code:

---

# In this example were unraring a file called lawl-eir.r00 which will extract it from all parts.
rar x /home/melon/lawl/lawl-eir.r00

---

Hope that helps :)
And sorry, but I don't really know how to do so if you don't have SSH access :(
