DECnet networking
CONFIG_DECNET
The DECnet networking protocol was used in many products made by
Digital (now Compaq). It provides reliable stream and sequenced
packet communications over which run a variety of services similar
to those which run over TCP/IP.
To find some tools to use with the kernel layer support, please
look at Patrick Caulfield's web site:
http://linux.dreamtime.org/decnet/
More detailed documentation is available in the
Documentation/networking/decnet.txt file.
Be sure to turn on the CONFIG_PROCFS and CONFIG_SYSCTL options
when using DECnet, since you will need sysctl support to aid in
configuration at run time.
DECnet SIOCFIGCONF support
CONFIG_DECNET_SIOCGIFCONF
This option should only be turned on if you are really sure that
you know what you are doing. It can break other applications which
use this system call and the proper way to get the information
provided by this call is to use rtnetlink.
DECnet Router Support
CONFIG_DECNET_ROUTER
Add support for turning your DECnet Endnode into a level 1 or 2
router. This is an unfinished option for developers only. If you
do turn it on, then make sure you also have rtnetlink configured
in, since thats the only current method of configuration.
DECnet Raw Socket Support
CONFIG_DECNET_RAW
Add support for the SOCK_RAW type under DECnet. Used by userland
routing programs to receive routing messages from the kernel and
also as a general debugging aid to see whats going on "under the hood".

EFS filesystem support (experimental)
CONFIG_EFS_FS
EFS is the filesystem used for CDROMs and filesystems by SGI's IRIX.
This implementation only offers read-only access. If you don't know
what all this is about, it's safe to say N. For more information

Universal Serial Bus (USB) Support (Experimental)
CONFIG_USB
This will enable support for the Universal Serial Bus (USB). USB
allows you to connect up to 127 external devices such as keyboards,
mice, printers and modems to your computer through a USB connector.
This code can also be built as a module (i.e. code outside the
kernel that can be added and removed at runtime), consult
Documentation/modules.txt for more information.
UHCI (intel PIIX4 and others) support
CONFIG_USB_UHCI
The UHCI is the USB host controller for many computers, and is built
into all recent boards with intel PCI chipsets. This driver is
needed for these motherboards to support USB.
OHCI (compaq and some others) support
CONFIG_USB_OHCI
The OHCI (Open Host Controller Interface) is the USB host controller
on most non-Intel architectures, several USB-adding PCI cards, and
is on several x86 compatibles with non-Intel chipsets. This driver
is needed for these motherboards to support USB. There is presently
two OHCI drivers in development. Say 'N' here if you would like to
compile the other OHCI driver into the linux kernel.
OHCI-HCD (other OHCI opt. Virt. Root Hub) support

is needed for these motherboards to support USB. There is presently
two OHCI drivers in development.
USB hub support
CONFIG_USB_HUB
To expand beyond the USB ports on the computer, a device called a
hub is used. This driver supports hubs, allowing them to be used.

USB mouse support
CONFIG_USB_MOUSE
This driver allows mice to work under the USB stack. It currently
patches into /dev/ps2aux, although it does not require the ps2
mouse code to be included in the kernel as well.
USB keyboard support
CONFIG_USB_KBD
This driver allows usb keyboards to work under the USB stack.
USB audio parsing support (Preliminary)
CONFIG_USB_AUDIO
This driver will eventually handle audio devices, such
as USB speakers.
USB Abstract Control Model support (Preliminary)
CONFIG_USB_ACM

TimRu-Erweiterungen:
====================
1. erfolglose Anwahlversuche per ICMP zurueckmelden
---------------------------------------------------
isdnctrl dialtimeout <name> <timeout>
name: Name des Interfaces
timeout: -1: kein Waehl-Timeout
0: jede Telefonnummer dialmax-mal probieren
>0: Zeitraum in Sekunden, in dem die Anwahl versucht wird
isdnctrl dialtimeout bewirkt, dass die Anwahl der Gegenstelle im Fehler-
fall nicht unbegrenzt versucht wird, sondern entweder nach einer bestimmten
Anzahl von Versuchen oder nach einem bestimmten Zeitraum abgebrochen wird
und alle ausstehenden Pakete fuer den durch isdnctrl dialwait bestimmten
Zeitraum mit ICMP_NET_UNREACHABLE beantwortet werden.
isdnctrl dialwait <name> <seconds>
name: Name des Interfaces
seconds: 0: keine Waehl-Unterdrueckung im Fehlerfall
>0: Zeit in Sekunden, in der nach einem erfolglosen Anwahl-
versuch Pakete mit ICMP_NET_UNREACHABLE beantwortet werden
1.1 einzelne Interfaces stoppen / starten
-----------------------------------------
isdnctrl status <name> <status>
name: Name des Interfaces
status: on: Interface einschalten
off: Interface ausschalten
Dieser Befehl wirkt wie 'isdnctrl system on/off' auf Interface-Ebene.
2. bessere Kontrolle ueber Aufbau und Hangup einer Verbindung
-------------------------------------------------------------
isdnctrl <cmd> <name> bringup <seconds> <rule>
isdnctrl <cmd> <name> keepup in <seconds> <rule>
isdnctrl <cmd> <name> keepup out <seconds> <rule>
isdnctrl <cmd> <name> keepup both <seconds> <rule>
cmd: addrule: Regel am Ende der Regelliste anfuegen
insrule: Regel am Anfang der Regelliste einfuegen
delrule: Regel loeschen
default: Was tun, wenn keine Regel passt?
showrules: alle Regeln anzeigen
flushrules: alle Regeln einer Art loeschen (bringup, ...)
flushallrules: alle Regeln loeschen
name: Name des Interfaces
seconds: Mindester Hangup-Timeout ab jetzt
rule: Regel, auf die ein Paket passen muss, damit die Verbindung
aufgebaut oder der Hangup-Timeout verlaengert wird
Eine passende Bringup-Regel erlaubt den Aufbau der Verbindung,
wenn ihr Timeout > 0 ist. Eine Bringup-Regel mit einen Timeout == 0
verhindert einen Verbindungsaufbau. Dieser Timeout muss eigentlich nur
so gross sein, dass die Verbindung zum Gegenrechner erfolgreich
zustande kommt, da das ausloesende Datenpaket danach durch die
Keepup-Logik 'geht' und der Hangup-Timeout erneut berechnet wird.
Eine passende Keepup-Regel verlaengert den Hangup-Timeout, wobei
nach eingehenden und ausgehenden Paketen unterschieden werden kann.
Die Kontrolle eines Paketes stoppt bei der ersten passenden Regel, falls
keine Regel anwendbar ist, gilt die Default-Regel.
Die Regeln haben folgenden Aufbau:
ip/icmp <src>/<mask> <type> <dst>/<mask>
ip/tcp <src>/<mask> <port> <dst>/<mask> <port>
ip/udp <src>/<mask> <port> <dst>/<mask> <port>
ip/* <src>/<mask> <dst>/<mask>
ip/any <src>/<mask> <dst>/<mask>
ipx/*
ipx/any
ppp/ipcp
ppp/ipxcp
ppp/ccp
ppp/lcp
ppp/chap
ppp/pap
ppp/lqr
ppp/*
ppp/any
*/*
any
src: Absender-Adresse des Paketes als Nummer oder Name
dst: Empfaenger-Adresse des Paketes als Nummer oder Name
mask: Subnet-Maske als Anzahl Bits oder als Maske
type: ICMP-Message-Type als Nummer
port: Portnummer als Nummer oder Name
Wildcards ('*', 'any') sind ueberall erlaubt.
Fuer <src> und <dst> gilt:
<host>: Host-Adresse als Nummer oder Name,
Subnet-Mask /32
<host>/<mask>: Host-Adresse als Nummer oder Name,
Subnet-Mask als Anzahl Bits oder Maske
<network>: Netzwerk-Adresse als Nummer oder Name,
Subnet-Mask /32
<network>/<mask>: Host-Adresse als Nummer oder Name,
Subnet-Mask als Anzahl Bits oder Maske
0.0.0.0/0
0/0
*
any: Wildcard, passt auf jede Adresse.
Fuer <ports> gilt:
<from>-<to>: alle Ports von <from> bis <to>, numerische Angabe
<from>-: alle Ports von <from> bis 65535, numerische Angabe
-<to>: alle Ports von 0 bis <to>, numerische Angabe
<port>: ein Port als Nummer oder Name
-, *
oder any: alle Ports
Beginnt die Regel mit einem '!' oder mit 'not', so dreht sich ihre Aussage um:
falls sie NICHT passt, wird die Verbindung aufgebaut, bzw. der
Hangup-Timeout verlaengert.
Default-Regeln werden folgendermassen angegeben:
isdnctrl default <name> bringup <timeout>
name: Name des Interfaces
timeout: 0: Verbindung wird nicht aufgebaut
>0: Verbindung wird aufgebaut, anfaenglicher Timeout
ist <timeout>.
isdnctrl default <name> keepup in <seconds>
isdnctrl default <name> keepup out <seconds>
isdnctrl default <name> keepup both <seconds>
name: Name des Interfaces
seconds: Mindester Hangup-Timeout
3. Budget-Erweiterungen
-----------------------
Diese Erweiterung erlaubt es, bestimmte 'Verbrauchswerte' pro
Zeitraum zu limitieren. Falls ein Budget aufgebraucht ist, findet
keine Anwahl mehr statt und eine bestehende Verbindung wird unterbrochen.
Sobald wieder alle Budgets verfuegbar sind, werden wieder Verbindungen
zugelassen.
Die Gebuehrenimpuls-Zaehlung setzt momentan auf der Uebertragung der
CINF-Pakete, also der Gebuehreninformation waehrend der Verbindung auf.
Unmittelbar nach Aufbau der Verbindung wird der erste Gebuehrenimpuls
'angenommen'.
Fuer ISDN-Anschluesse, bei denen die Gebuehren erst am Ende der Ver-
bindung uebertragen werden, faellt uns bestimmt auch noch was ein ;-).
isdnctrl budget <name> <budget-type> <amount> <period>
setzt die Werte eines bestimmten Budgets. Ein aufgebrauchtes
Budget wird unmittelbar wieder aktiviert.
budget-type: dial: Anzahl der Anwahlversuche (erfolgreich oder
erfolglos) pro Periode
charge: Anzahl der Gebuehreneinheiten pro Periode
online: Online-Zeit pro Periode
amount: Hoehe des Budgets. Bei <budget-type> 'dial' oder 'charge'
ist das die Anzahl Anwahlen oder Einheiten, bei 'online'
eine Zeitangabe (s.u.)
period: Dauer der Periode in folgendem Format (<n> steht fuer eine
natuerliche Zahl):
<n>
<n>s
<n>sec, <n> Sekunden
<n>m
<n>min, <n> Minuten
<n>h
<n>hour, <n> Stunden
<n>d
<n>day, <n> Tage
<n>w
<n>week, <n> Wochen (a 7 Tage)
<n>M
<n>month, <n> Monate (a 30 Tage)
<n>y
<n>year, <n> Jahre (a 365 Tage)
Diese Angaben koennen miteinander kombiniert werden, z.B.:
2h30m15
2hour,30min,15sec
1M2week,1day,8h
isdnctrl budget <name> <budget-type> off
schaltet die Kontrolle des entsprechenden Budgets aus
isdnctrl budget <name> showbudgets
zeigt die momentaten Budgets an
isdnctrl budget <name> savebudgets
gibt die momentaten Budgets in einen Format aus, das vom Befehl 'restore-
budgets' wieder eingelesen kann
isdnctrl budget <name> restorebudgets <saved-budget> ...
setzt die Budgets wieder auf die vorher mit 'savebudgets' ausgegebenen
Werte. Damit koennen Budgets auch ueber den Reboot der Maschine hinaus
Gueltigkeit haben.
Hier ein Beispiel fuer die TimRu-Erweiterung:
# Alle Regeln loeschen
isdnctrl flushallrules ippp0
# Default: jeder Datenverkehr setzt den Hangup-Timeout auf 60 Sek.
isdnctrl default ippp0 keepup both 60
# FTP und Telnet erhoehen den Timeout auf 5 Minuten
isdnctrl addrule ippp0 keepup both 300 ip/tcp 0/0 20-23 0/0 -
# Anzeige der Regeln:
isdnctrl showrules ippp0
# ... erzeugt folgende Ausgabe:
Timeout rules for interface ippp0:
Default bringup policy: true
Default huptimeout for incoming packets: 60 sec.
Default huptimeout for outgoing packets: 60 sec.
Current huptimeout: 60 sec.
Time until hangup: 45 sec.
Keepup-rules for incoming ip-packets:
1-1-0 keepup_in 300 ip/tcp 0/0 20-23 0/0 *
Keepup-rules for outgoing ip-packets:
2-1-0 keepup_out 300 ip/tcp 0/0 * 0/0 20-23
Hier ein Beispiel fuer die Budget-Erweiterung:
# Hoechstens 60 Anwahlversuche pro Stunde
isdnctrl budget ippp0 dial 60 1h
# Hoechstens 3000 Einheiten pro Monat
isdnctrl budget ippp0 charge 3000 1M
# Hoechstens 8 Stunden online pro Tag
isdnctrl budget ippp0 online 8h 1d
# Anzeige der Budgets:
isdnctrl showbudgets ippp0
# ... erzeugt nach kurzer Zeit folgende Ausgabe:
Budgets for interface ippp0:
TYPE AMOUNT PERIOD USED SINCE
dial 60 1h 1 01.07.1997, 17:43:40
charge 3000 1M 2 01.07.1997, 17:43:49
online 8h 1d 2m26s 01.07.1997, 17:43:57
Zum Nachfuehren der Budgets ueber einen laengeren Zeitraum koennte man
folgende Methode verwenden:
beim Herunterfahren oder per 'cron' jede Minute:
INTERFACES="ippp0 ippp1 ippp2"
for i in $INTERFACES; do
isdnctrl savebudgets $i > /var/isdn/saved-budgets/$i
done
und dann beim Neustart:
for f in /var/isdn/saved-budgets/*; do
isdnctrl restorebudgets ${f##*/} `cat $f`
done

Linux DECnet Networking Layer Information
===========================================
1) Other documentation....
o Project Home Pages
http://www.sucs.swan.ac.uk/~rohan/DECnet/index.html - Kernel info
http://linux.dreamtime.org/decnet/ - Userland tools
o FTP sites
ftp://ftp.sucs.swan.ac.uk/pub/Linux/DECnet/
- Swansea University Computer Society DECnet Archive
(contains kernel patches and info)
- Mirror of userland tools on ftp.dreamtime.org
ftp://ftp.dreamtime.org/pub/linux/decnet/
- Patrick Caulfield's archive of userland tools and
Eduardo Serrat's kernel patches
2) Configuring the kernel
Be sure to turn on the following options:
CONFIG_DECNET (obviously)
CONFIG_PROCFS (to see what's going on)
CONFIG_SYSCTL (for easy configuration)
if you want to try out router support (not properly debugged and not
complete yet), you'll need the following options as well...
CONFIG_DECNET_RAW (to receive routing packets)
CONFIG_DECNET_ROUTER (to be able to add/delete routes)
CONFIG_NETLINK (to allow rtnetlink)
CONFIG_RTNETLINK (for communication with the kernel routing layer)
3) Command line options
The kernel command line takes options looking like the following:
decnet=1,2,1
the first two numbers are the node address 1,2 = 1.2 (yes, you must use
commas when specifying them). The third number is the level number for routers
and is optional. It is probably a good idea to set the DECnet address on boot
like this rather than trying to do it later.
There are also equivalent options for modules. The node address and type can
also be set through the /proc/sys/net/decnet/ files, as can other system
parameters.
Currently the only supported device is ethernet. You'll have to set the
ethernet address of your ethernet card according to the DECnet address
of the node in order for it to be recognised (and thus appear in
/proc/net/decnet_dev). There is a utility available at the above
FTP sites called dn2ethaddr which can compute the correct ethernet
address to use. The address can be set by ifconfig either before at
at the time the device is brought up. If you are using RedHat you can
add the line:
MACADDR=AA:00:04:00:03:04
or something similar, to /etc/sysconfig/network-scripts/ifcfg-eth0 or
wherever your network card's configuration lives.
You will also need to set /proc/sys/net/decnet/default_device to the
device you want DECnet to route packets out of when no specific route
is available. Usually this will be eth0, for example:
echo -n "eth0" >/proc/sys/net/decnet/default_device
There is a list of what the other files under /proc/sys/net/decnet/ do
on the kernel patch web site (shown above).
4) How can I tell if its working ?
Here is a quick guide of what to look for in order to know if your DECnet
kernel subsystem is working.
- Is the node address set (see /proc/sys/net/decnet/node_address)
- Is the node of the correct type (see /proc/sys/net/decnet/node_type)
- Is the Ethernet MAC address of each Ethernet card set to match
the DECnet address. If in doubt use the dn2ethaddr utility available
at the ftp archive.
- If the previous two steps are satisfied, and the Ethernet card is up,
you should find that it is listed in /proc/net/decnet_dev and also
that it appears as a directory in /proc/sys/net/decnet/conf/. The
loopback device (lo) should also appear and is required to communicate
within a node.
- If you have any DECnet routers on your network, they should appear
in /proc/net/decnet_neigh, otherwise this file will only contain the
entry for the node itself (if it doesn't check to see if lo is up).
- If you want to send to any node which is not listed in the
/proc/net/decnet_neigh file, you'll need to set the default device
to point to an Ethernet card with connection to a router. This is
again done with the /proc/sys/net/decnet/default_device file.
- Try starting a simple server and client, like the dnping/dnmirror
over the loopback interface. With luck they should communicate.
For this step and those after, you'll need the DECnet library
which can be obtained from the above ftp sites as well as the
actual utilities themselves.
- If this seems to work, then try talking to a node on your local
network, and see if you can obtain the same results.
- At this point you are on your own... :-)
5) How to send a bug report
If you've found a bug and want to report it, then there are several things
you can do to help me work out exactly what it is that is wrong. Useful
information (a lot of which is essential) includes:
- What kernel version are you running ?
- What version of the patch are you running ?
- How far though the above set of tests can you get ?
- What is in the /proc/decnet* files and /proc/sys/net/decnet/* files ?
- Which services are you running ?
- Which client caused the problem ?
- How much data was being transfered ?
- Was the network congested ?
- If there was a kernel panic, please run the output through ksymoops
before sending it to me, otherwise its _useless_.
- How can the problem be reproduced ?
- Can you use tcpdump to get a trace ? (N.B. Most (all?) versions of
tcpdump don't understand how to dump DECnet properly, so including
the hex listing of the packet contents is essential, usually the -x flag.
You may also need to increase the length grabbed with the -s flag)
6) Mailing list
If you are keen to get involved in development, or want to ask questions
about configuration, or even just report bugs, then there is a mailing
list that you can join: send mail to majordomo@dreamtime.org with
subscribe linux-decnet
as the body of the message.

Hello folks,
The CMI8330 soundchip is a very small chip found on many recent
motherboards. In order to use it you just have to use a proper
isapnp.conf and a little bit of patience.
[Note: The CMI 8338 is unrelated and right now unsupported]
Of course you will have to compile kernel sound support as module,
as shown below:
In order to use CMI8330 under Linux you just have to use a proper isapnp.conf, a good isapnp and a little bit of patience. I use isapnp 1.17, but
you may get a better one I guess at http://www.roestock.demon.co.uk/isapnptools/.

Audio driver for CM8338/CM8738 chips by Chen-Li Tien
Be aware: C-Media Electronics Inc. is basically an IC design house,
and whose development of software drivers is mainly for use by its OEM
customers in their products. C-Media Electronics Inc. itself does not
manufacture end-user products, such as PC or sound cards, so it can
not fully control the drivers provided to consumers. Drivers provided
at this site, therefore, MAY NOT BE APPLICABLE to all sound cards.
Drivers you download from this site may function well at certain
situation, but C-Media Electronics Inc. does not give any guarantee or
assurances. Please be aware that these drivers might cause some
technical difficulties when installed
1. Config cm8338 driver by 'make menuconfig' or 'make config' command.
2. Please select Sound Card (CONFIG_SOUND=m) support and CMPCI driver (CONFIG_SOUND_CMPCI=m) as modules. Resident mode not tested.
3. Compile the kernel if necessary.
4. Compile the modules by 'make modules'.
5. Install the modules by 'make modules_install'
6. Before first time to run the driver, create module dependency by 'depmod -a'
7. To install the driver, enter 'modprobe cmpci'.
Bugs:
1. Real player cannot be run (the same as es1371).
