I'll try to help.
If you use a conventional tool, even wget, you are making one connection to
a remote server. If that server goes down, or slows down, your transfer
slows down too. Regardless of the bandwidth you have available, you are
limited by the bandwidth of the remote server (or of the slowest link
between you).
Again, if the transfer is interrupted, you lose. You must start again.
More than once, I've lost a complete Red Hat download because, after
downloading 80% of (say) a CD image, the connection failed somewhere and all
was lost.
BitTorrent establishes multiple connections between your computer and others
which have the files you want. The files are transferred in multiple
pieces. If a single connection fails, you only lose a portion of the data
you are transferring; the previously downloaded parts are still valid.
Since you have multiple connections, you are less likely to overwhelm any
one of them, and more likely to use all of the bandwidth you have to receive
data.
BitTorrent manages the incoming pieces and makes sure they are intact and
correct.
In payment for a more-efficient download, your system also turns into a
server for the length of time you are running BitTorrent. So others are
downloading from you at the same time you are downloading from others.

Realtime traceroute
by Kenneth Porter
Does anyone know of a realtime traceroute that can be used to show
anomalous routers?
I'm having an issue while gaming in which I'll see my ping to an unrelated
server suddenly and momentarily spike, which tells me that some router
close to me is having a short-term issue. But because it's not a continuous
problem, I can't tell where it's happening.
Ideally I'd like a set of strip chart graphs showing ping times to all
routers between me and a selected server, effectively a realtime traceroute
that I can check when my ping shoots up.
(I'm gaming on a Windows box while leaving a ping running to a different
server on my Fedora box. When I get dropped from the game server by
"connection issues", I use my KVM to switch to my Fedora screen and see a
momentary jump from about 100 ms to 1000 ms in ping.)
BTW, my residential router is a Linksys WRT54G running Sveasoft Satori
Linux with QoS enabled. I'm not inclined to think that it's the problem.
But there might be a spike in bandwidth elsewhere in my LAN that could be
an issue. A measurement of packet loss at the Linksys could be useful, but
I don't know how to look for that and am open to suggestions.

(OT) Bit Torrent usage ...
by Mike McCarty
I see that the Red Hat site suggests Bit Torrent.
I went to the website, and I don't see where it would
help. And I don't understand the bit about "if you don't
allow Bit Torrent to upload from your machine, you won't
get improved download rates."
They specifically state that it is a means for publishing
things from one's own machine to the world.
Can anyone explain, in ordinary language, what possible
advantage it would give me over, say, wget?

usb problems after recent updates
by Chris Jones
Hi,
I'm running FC4 on a laptop been experiencing usb problems since the last
round of FC4 updates. Basically the symptoms are that if I plug in my usb
mouse, which has worked find up to this point, the system goes into a cycle
of 100% cpu usage for a few seconds, which then stops for a period and then
restarts. The mouse does not work (It might for a few seconds but then
stops). Thankfully the touchpad works OK...
Does anyone else have this problem ? Any suggestions what to do would be
greatfully received as this is rather annoying.

User has computer locked
by Stanley Davis
Is there a way to unlock/logoff a user that has the computer locked without knowing their password? The computer in question is a stand alone computer. I know in the Windows environment that any administrator should unlock and signoff the current user. Is the same possible under Fedora Core 4? Also is there a way to limit when a user can be logged into a computer, for example user1 can only logon between 9AM and 3PM.

Prelink eating all my resources
by Dotan Cohen
Hi list,
Once again my FC4 box (Duron 1200mHz, 512 ram) has crawled to a halt.
I quickly top'ed and found a process prelink that varied between
74%-98% CPU usage.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
5202 root 39 19 11724 9280 536 R 89.9 1.9 0:23.59 prelink
So I googled for prelink and now know that it helps preload libraries
so that progreams can start faster. Which is senseable because the
machine started slowing down when I clicked 'manage bookmarks' in
firefox, which opens another program. My question is, what can I do to
prevent this from happening again? Do I have to ust cross my fingers
every time I open a new program?
Could this be related to the fact that I have no swap partition? I
know that I should probably add one, I guess that I've just been too
lazy to learn how. Will adding a swap partition make the machine less
sluggish? For this 512 ram machine, I was thinking of adding a 2 gig
swap partition.
