Ethereal?

[Hiisi]

Hi, list!
I've been trying to learn networks. In the book I'm using they use
Ethereal programm along side with tcpdump to catch packets. I already
have tcpdump installed. Yum shows me that Ethereal is provided by
wireshark package that's also installed:
$ yum provides ethereal
Loaded plugins: fastestmirror, presto, refresh-packagekit, show-leaves
wireshark-1.2.2-1.fc12.i686 : Network traffic analyzer
Repo        : fedora
Matched from:
Other       : ethereal

wireshark-1.2.11-1.fc12.i686 : Network traffic analyzer
Repo        : updates
Matched from:
Other       : ethereal

wireshark-1.2.11-1.fc12.i686 : Network traffic analyzer
Repo        : installed
Matched from:
Other       : Provides-match: ethereal

However if I try to run 'ethereal' command I've got:
$ ethereal
-bash: ethereal: command not found
So, my question is how to use it?
TIA
