Ethereal problem ? & some other issues....??

Hi there
im very new to linux and networking. I have installed ethereal and
using rpm , it does show that i have ethereal installed. But somebody
told me that you can start ethereal by typing following at bash
$ ethereal
but when i type above it says bad command. now when i type "tethereal"
it works and says the following
Capturing lo
now is "ethereal" and "tethereal" a same thing?

I have heard there is a graphical version of ethereal as well, how can
i invoke that from shell/bash?
any help will be highly appreciated....please reply
ANOTHER QUESTION IS how can i make ordinary user as powerful as root
on my redhat?
LAST QUESTION IS i have dualed boot red hat 8 and windows XP, now i
want to save some files from my linux to XP? howz that possible
im really stumped so please help

cheeers

you can try this command to locate files:
whereis ethereal
mine produced
/usr/bin/ethereal
so type in /usr/bin/ethereal

1. ethereal is the gui for tethereal. If you don't have ethereal in your
path or installed, then you'll have to install it first, and have a working
X system to use the gui (it runs in graphics mode). Another option is to use
tethereal to save your capture in a file and then send the file to another
PC with ethereal.
2. to give root privileges to a user, assing the user to the root group. In
/etc/group add your user next to the line beginning with root:x:0:root
3. you need to mount your winxp partition first in order to use it. Suppose
your hard disk is /dev/hda, the type "fdisk /dev/hda -l" and check for the
partition name of the partition with FAT 32 filesystem, suppose it's hda3.
Create a directory like /mnt/windows and mount the partition with: "mount
/dev/hda3 /mnt/windows". If you get an error you may need to include support
in your kernel for the filesystem used by windows (eg: Fat 32, NTfs, so on).

good luck,

Assuming you have it.

Other methods are
find /usr -iname 'ethereal'
Or if you have the locate package:
locate ethereal

Find searches all files within a directory tree (can be slow), locate checks
a database of files, and whereis searches in very specific places (so it
doesn't necessarily find all things that you have installed). Here are the
paths it checks on my system:

/{bin,sbin,etc}

/usr/{lib,bin,old,new,local,games,include,etc,src,man,s bin,
X386,TeX,g++-include}

/usr/local/{X386,TeX,X11,include,lib,man,etc,bin,games,emacs}

!dangerous!

The above is a neat idea, but there are many more standard and slightly
safer solutions:

If you want to execute a program as root but from a user account regularly,
the normal way to do that is to use the setuid bit. As root, find the
location of the executable, for example, by running "which tethereal", then
do the following:
chmod u+s <path-to-file>
Note however, that if the file is a script, you might need to create an
executable wrapper, which you would then setuid root.

Other methods that are typical of linux are using su -c and sudo. You can
look up info using "man su" and "man sudo".

Presumably you want to be able to run [t]ethereal without being root, and
your difficulty is that it requires CAP_NET_RAW, which is normally only
granted to root, is that so? Then, you can use the capability kernel
module at
http://lwn.net/Articles/80239/
Instead of granting root privilege to the program at all.

If you mean to give a normal user root-like privileges on a normal basis,
without any well-defined restriction, you should really, really think hard
about doing so. Even setuid programs are considered slightly dangerous, if
sometimes necessary. Post on comp.os.linux.security, and ask about it if
you want.

May you be using a FAT-based system, or you might have some difficulty,
because NTFS write support has been problematic. You might also need to
specify a -t option to mount:
mount -t auto /dev/hda3 /mnt/windows

Or
mount -t vfat ... [e.g., for win95 style partition]
mount -t ntfs ... [e.g., usu. for xp]

Once you have figured out how to mount it, you can edit your /etc/fstab file
so that the process is automated. To find out more, do "man fstab".

Good luck,

Jon.
