cFos/Win 5.00, 05-Feb-2003
cFos/NT 5.00, 05-Feb-2003
! cFos Traffic Shaping! Surf the web faster with less
latency with cFos Traffic Shaping. For details, see
http://www.cfos.de/techinfo/shape.htm
* Drag and Drop of keyfile from your mail program to cFos status
window.
* Firewall improvement with FTP transfers: FTP servers often try
to IDENT connecting machines (i.e. they try to connect to your
IDENT services). Those requests are, if they are blocked by the
firewall, often repeated like 4 times, delaying FTP server login
for e.g. some 4 seconds. cFos now rejects the IDENT connection,
if there is a FTP control connection to the same host running at
the same time, resulting in a faster FTP login.
* The Firewall is now keeping state of TCP connections. This
allows cFos to do "Port stealthing"! I.e. if someone is trying
to connect to your computer, but the respective port is not in
listen state, the remote machine does not receive a RST segment.
I.e. the remote machine does not know that your computer even
exists! Only if the port exists and is in listen state (i.e.
you are offering a server to the net) incoming connections will
result in packets beeing sent to the net.
The same holds true for UDP ports: if a remote machine tries to
connect to one of you UDP ports currently not in listen state,
it will not receive negative feedback, effectively "stealthing"
this port.
* Refinement for S86 TX inactivity timer: data that is sent by
your computer as an automated response without any useful
payload (like PING replies and the like) and data that is
filtered out by cFos Firewall will no longer keep the
inactivity timer alive.
If you use inactivity timers to disconnect your PC from the
Internet we recommend using S86 instead of S19 or S85, because
S86 keeps working even with the constant bombardment of eDonkey
(or the like) connection attempts or other people trying to
get into your PC.
* cFos now has the ability to synchronize your computer's clock
with time servers on the Internet!
If you select "Time Sync" in SETUP, cFos will try to get the
correct time at least 18 hours after the last timesync. It
will try do so automatically 10 seconds after you logged on
to the Internet. You have a context menu option to do it
manually, too.
cFos has built-in lists of free timeservers for each
geographical location, but if you want to use a specific
server, set the TimeServer= variable in the [cFos] section of
CFOS.INI to the name of that server and cFos will use only
this.
cFos has (for some time now) the ability to sync your
computer's clock with ISDN time, too. It will use both time
sync possibilities if it can. E.g., if you get ISDN time
infos every 12 hours, Internet time sync will never be used.
If ISDN Time-Sync and Internet Time-Sync work against one
another, you can disable either of them: -ji to disable ISDN
time-sync, -jn to disable Internet time-sync. Set the
switches in the Parameter line in SETUP.
* cFos can reduce the MTU on PPPoE connections with a setting of
register S99. Either use S99=<MTU in your init string or use
-x99=<MTU in the parameter line of cFos Setup (replace <MTU
with the MTU number).
To maximize data thruput cFos/Win must make changes to the
IPMTU setting in the registry. Set the -km switch in Setup
to disable these changes to the registry.
cFos checks now to see the minimum MRU advertised by either
side and uses the smaller value as MTU. This way, you
don't have to set -x99 even if your ISP requires smaller MRUs
because of further tunnelling. This works as long as the ISPs
dialin host tries to negotioate this smaller MRU. If it does
not, you need to use -x99 feature mentioned above.
* You can now allow / ignore calls with certain caller IDs.
Default is to allow all calls. If you'd like to limit the
calls cFos listens to to a certain set of caller IDs, you can
create a section [callerid] in the CFOS.INI file. In this
section you can specify include= and exclude= keys. On an
incoming call, cFos scans through this [callerid] section and
allows / disallows a certain caller ID whenever it matches with
a key. The character * indicates that the reminder of the
number is not used for a match. Example:
[callerid]
exclude=* ; exclude all numbers
include=0228* ; but allow all calls from Bonn
exclude=0228555* ; but exclude calls from these numbers
include=0405551234 ; and allow one certain number from Hamburg
You could, for example, use cFos in combination with a
remote control software and only allow certain users with
fixed caller IDs to dial into the computer and do remote
maintenance. This adds one more layer of security.
* You can now dump all data that is sent to resp. received from
your ISDN board resp. your DSL modem. The switches -dp (put,
i.e. sent) and -dg (get, i.e. receive) switch this kind of
logging on. Output goes into CTRACE.TXT.
* Redirected ISDN calls are now indicated as such in the cFos
caller monitor window.
* New cFos Skin, optimized for the look and feel of Windows XP.
* Skins now support indication of PPP login states and firewall
activity, Skin monitor windows can inidicate redirected calls.
* Added alpha-blending support fuer the skins, see skin.htm for
details.
* Skins now support color transformation to easily create
variations of existing skins. See skin.htm for details.
* Connection Reports are now generated out of report.tpl and
report_e.tpl, which are actually html. So you can design your
own connection reports now, using most of the skin variables.
* You can specify the budget to use in the phone number you dial:
include "=<budget" (sans quotes) in the number, where <budget
may be 0 to disabled budget, 1-9 for budgets 1 to 9 or 'a' for
budget 10. Example: "ATD=15551234" will dial 5551234 and use
budget 1; "ATD5551234=A" will dial the same number, but use
budget 10 instead.
* You want to prioritize some UDP or TCP ports? Use
FastOutUdpSport, FastOutUdpDport, FastOutTcpSport,
FastOutTcpDport to prioritize UDP or TCP packets with
the respective source port number (Sport) or destination port
number (Dport) with TX CTS. May be useful for e.g. online
games. The settings have to be in the [cts] section of
cfos.ini and can hold multiple values each, spaced by spaces
or commas, like:
[cts]
fastoutudpdport=9990 9991
* Display the amount of remaining inactivity time by setting
S74.14=1. It is displayed in the position of the connect
charges.
* You can now set bits in S-registers on the command line with
-x<reg.<bit=<v, where <reg is the number of the register,
<bit the bit number and <v either 0 or 1. E.g. -x74.14=1
will activate the display of inactivity time.
- ISDN time info is now a global value, instead of a port-
specific value. This could help determining if you get
ISDN time info messages from CAPI / Telco.
x Bugfixes in Skin-Support and Connection Report.
cFos/Win
* You can call CFOSDW.EXE with -s[n]<x parameter to display
one or all status windows. -sn means don't close after 5 secs.
<x is the window number, 0=first COM port, 1=next COM port,...
highest number is caller monitor window. Leaving out <x opens
all windows.
cFos/NT
* The Shareware version will now work even if no user is logged
on to the computer. The registered version always did.
* Removed the Start/Stop service and Quit status window entries
from the context menu. Only if the startmode is set to manual
or the service in not running yet, the appropriate entries are
displayed.
* Under XP the ballon tip with the logon message sometimes stays
active for minutes. cFos now closes the ballon tip after 15
seconds or after the amount of milliseconds mentioned in the
LogonBallonTime setting in the [cfos] section in cfos.ini.
* You can stop the CFOSDNT.EXE now by starting "CFOSDNT -d".
