QNetwalk is a Qt-version of the popular NetWalk game
for system administrators :)
Rules of play:
* You are the system administrator and your goal is
to connect each computer to the central server.
* Click the right mouse's button for turning the cable
in a clockwise direction, and left mouse's button for
turning the cable in a counter-clockwise direction.
* Start the LAN with as few turns as possible!

does the error checking for us.
- henning@cvs.openbsd.org 2004/09/16 01:10:05
[imsg.c]
in imsg_compose:
-don't buf_free() on imsg_add() errors, it already does that for us
-use imsg_close() instead of buf_close(), does error handling already
- henning@cvs.openbsd.org 2004/09/16 01:13:42
[imsg.c ntpd.h]

- henning@cvs.openbsd.org 2004/09/18 20:01:38
[client.c ntp.c ntpd.8 ntpd.c ntpd.h]
add a new -s option, that tells ntpd to set the time using settimeofday()
once at startup. ntpd delays daemonizing until it has done the intial
time setting (or ran into the timeout) in this mode to make sure stuff
started later in rc is not subject to time jumps.
this eleminates the need to run rdate -n beforehands.
with some input from & ok ryan and bob, march music from mickey

[client.c]
now that we connect() the client sockets we need to handle ECONNREFUSED as
non-fatal too, from camield@
- henning@cvs.openbsd.org 2004/10/04 11:12:58
[ntp.c]
do not take the average offset from all peers when calculating the total
offset to correct the local clock, but use the median.
given a reasonable sized set of servers this makes us nearly immune against
outliers or flasetickers, without the need for a horribly complicated
outliers detection which does not yield to better results anyway.
- henning@cvs.openbsd.org 2004/10/05 11:23:28
[client.c]
in client_addr_init() and client_nextaddr(), do not set up the socket and
connect it, instead leave it at -1.
in client_query, set up and connect the socket if it is -1.
and, the real reason for this change: handle connect failures gracefully
ok otto

- henning@cvs.openbsd.org 2004/10/13 09:20:41
[ntp.c]
when we get back a IMSG_HOST_DNS message from the parent the peer ID within
might have become invalid (because the peer showed up, dns request sent to
parent, peer vanishes, and then the reply comes back), so do not fatal() in
that case but just log_warnx(). provoked by brad
- henning@cvs.openbsd.org 2004/10/13 12:22:39
[ntp.c server.c]
correctly set refid in replies with NTP protocol versions < 4.
code path for NTP4 remains unchanged, we already set refid correctly there.
NTP3 and older uses an IPv4 address as refid.
use the IP of the server we last synced to if it was a IPv4 one.
sometimes we use the average offset between two, in that case just pick
one for the IP.
this scheme naturally fails when we query IPv6 servers and have to reply
to IPv4 NTP3 (or even older NTP versions) clients - refid stays at 0 then.
this is a protocol limitation, nothing we can do about it.

- henning@cvs.openbsd.org 2004/10/13 14:02:50
[ntp.c server.c]
set rootdelay in replies.
inherit rootdelay from the delay from the last client update from the peer
that we picked last time to adjust the local clock.
in some cases we use the average offset between two peers' client updates,
then use the average delay between the two as well.

What's new? Well, most importantly, the document watch feature has been
ported to gnome-vfs file monitoring capabilities, fixing annoying
misbehaviour of GGV while watching over remote documents. Apart from
that a few minor bugs were fixed and ghostscript was caught occasionally
running without the "-dSAFER" switch: this rather dangerous habit was
prohibited immediately!
GGV is now also a bit less of a narcist: it does not include "GGV" in
the desktop entry name - it's only "PostScript Viewer" now, following
the fine examples of eog and gpdf.
The recent-files module has been updated to the one in latest libegg.
Multiple updated translations.

the popular top Unix command does. ntop is based on libpcap and it has been
written in a portable way in order to virtually run on every Unix platform and
on Win32 as well.
ntop users can use a web browser (e.g. netscape) to navigate through ntop (that
acts as a web server) traffic information and get a dump of the network status.
In the latter case, ntop can be seen as a simple RMON-like agent with an
embedded web interface.
The use of:
- a web interface
- limited configuration and administration via the web interface
- reduced CPU and memory usage (they vary according to network size and traffic)
make ntop easy to use and suitable for monitoring various kind of networks.
