Ethereal is licensed under the GNU General Public License:

	http://www.gnu.org/licenses/gpl.html

so you can install Ethereal anywhere you want:

	You may copy and distribute verbatim copies of the Program's source 
code as you receive it, in any medium, provided that you conspicuously 
and appropriately publish on each copy an appropriate copyright notice 
and disclaimer of warranty; keep intact all the notices that refer to 
this License and to the absence of any warranty; and give any other 
recipients of the Program a copy of this License along with the 
Program.

and

	You may copy and distribute the Program (or a work based on it, under 
Section 2) in object code or executable form under the terms of 
Sections 1 and 2 above provided that you also do one of the following:

		o 	a) Accompany it with the complete corresponding machine-readable 
source code, which must be distributed under the terms of Sections 1 
and 2 above on a medium customarily used for software interchange; or,

		o 	b) Accompany it with a written offer, valid for at least three 
years, to give any third party, for a charge no more than your cost of 
physically performing source distribution, a complete machine-readable 
copy of the corresponding source code, to be distributed under the 
terms of Sections 1 and 2 above on a medium customarily used for 
software interchange; or,

		o 	c) Accompany it with the information you received as to the offer 
to distribute corresponding source code. (This alternative is allowed 
only for noncommercial distribution and only if you received the 
program in object code or executable form with such an offer, in accord 
with Subsection b above.)
The source code for a work means the preferred form of the work for 
making modifications to it. For an executable work, complete source 
code means all the source code for all modules it contains, plus any 
associated interface definition files, plus the scripts used to control 
compilation and installation of the executable. However, as a special 
exception, the source code distributed need not include anything that 
is normally distributed (in either source or binary form) with the 
major components (compiler, kernel, and so on) of the operating system 
on which the executable runs, unless that component itself accompanies 
the executable.

	If distribution of executable or object code is made by offering 
access to copy from a designated place, then offering equivalent access 
to copy the source code from the same place counts as distribution of 
the source code, even though third parties are not compelled to copy 
the source along with the object code.

It might even be that installing it throughout Petrobras isn't 
considered "copying and distributing", so you might not even have to 
worry about the requirements of that clause.  (I'm not a lawyer, so I 
don't know whether that's the case or not.)
