LPT porti in linux...

To bo mogoče malo tricky ampak vseeno močno upam, da se je kdo ze ukvarjal s tem ali da ima kako idejo...

Torej imam Wibukey dongle in gonilnik zanj za Linux.
Sistem je Redhat 8. Ko nastavim okoljske spremenljivke (environment variables) za gonilnik in ga zaženem vedno dobim isto sporočilo: 0 ports scanned... bla bla
0 wibu keys found.
Imam občutek, kot da gonilnik ne more odpreti ali najti portov. Katera je sploh prava, najboljsa oznaka paralelnega porta v Linuxu (/dev/lp, /dev/parport, /dev/ttyp ali kaj drugega)?
Kot namig sem nekje zasledil da je potrebno pred zagonom gonilnika uporabiti nekaj v stilu:
chmod o+rw /dev/ttys[0]
da se nastavijo "permissions". Je tak zapis v redu in ali je mogoče, da je ravno v dovoljenjih problem? No, ta ukaz sem tudi poskušal izvesti tako kot je napisan, pa ni pomagalo.

No pa da vidimo... za pir!

modprobe mislim da ne bo pomagal. Mislim da so se ti moduli za porte naložili na začetku, čeprav ne vem točno, kako bi preveril. Čudno je, ker k temu driverju za dongle ni nobenega helpa.
Zraven je en file za nastavljanje okoljskih spremenljivk, in jih tudi razlaga. Da bi lažje razumeli, za kaj gre, bom ga kar tule pastal. Upam da to ni prepovedano in se opravičujem za daljši post, če pa je to prepovedano, mi povejte, da vem za naslednjič.
Torej:

### WIBUenv: These are the settings for the WIBUKEY Environment.
### This file is for calling from ~/.bashrc or other shells.
### The examples in this File are showing the default values, marked with
### '(default)', that values are implemented at runtime if now ENVs
### are found.

###
### WKPORTNAME is the pathname of your serial port WITHOUT the last
### number or character!
### Make sure you have made a 'chmod o+rw /dev/ttyS[01]' as root !
### e.g.: export WKPORTNAME="/dev/ttyS" (default)
### This is for "/dev/ttyS0" up to "/dev/ttyS3"
### the numbers (0,1,2 or 3) are added by the Wibu API.
###
export WKPORTNAME="/dev/ttyS"
#export WKPORTNAME="/dev/cua"

### *
### * The complete Path to Port is build with WKPORTNAME and appended
### * digits: '0', '1', '2' or '3' if WKPORTENUM="DIGIT" or
### * chars 'a', 'b', 'c' or 'd' if WKPORTENUM="ALPHA".
### *

###
### WKPORTENUM is the kind of port enumeration: (Thanks to Bruce Fitzsimons)
### Possible Values are: "ALPHA" and "DIGIT".
### e.g.: export WKPORTENUM="ALPHA"
### This is SUN like: Some machines have /dev/tty[abcd].
### So we add an 'a' (97=0x61) offset of ASCII to get a '/dev/tty'[abcd].
### e.g.: export WKPORTENUM="DIGIT" (default)
### This is LINUX (SuSE) like: /dev/ttyS[0123].
###
export WKPORTENUM="DIGIT"

###
### WKCOM is describing the ammount of your serial ports.
### Possible Values are '*' (connected) or '/D' (not connected = disabled).
### Make sure you have a WIBU-Box /ST connected to your first
### COM-Port: '/dev/ttyS0' is assumed.
### e.g.: export WKCOM="*,*,/D,/D" (default)
### This is for 'COM1' and 'COM2' accessible.
###
#export WKCOM="/D,/D,/D,/D"
export WKCOM="*,/D,/D,/D"
#export WKCOM="*,*,/D,/D"
#export WKCOM="*,*,*,/D"
#export WKCOM="*,*,*,*"

###
### WKSYSTEM is the order of lookup for boxes.
### Possible values are: "Kernel", "WkLan"; ("WkNet" is not implemented)
### e.g.: export WKSYSTEM="Kernel,WkLan" (default)
###
export WKSYSTEM="Kernel,WkLan"
#export WKSYSTEM="Kernel"
#export WKSYSTEM="WkLan"

###
### WKSERVERNAME is your WkLan Servers' name.
### Possible values are all Server Names that coul be resolved by '/etc/hosts'
### files or 'nslookup'.
### e.g.: export WKSERVERNAME="localhost" (default)
###
export WKSERVERNAME="localhost"
#export WKSERVERNAME="server.domain.area"

###
### WKIPPORT is the port on which WkLan Server is listening for box requests.
### Posssible values are all valid port numbers (see /etc/services).
### e.g.: export WKIPPORT="22347" (default)
###
export WKIPPORT="22347"

###
### WKBAUDRATE is the Baudrate (in/out is the same), to communicate with Box /ST
### Possible Values are: "4800", "9600", "19200", "38400", "57600"
### Boxes are testet with "4800" and "57600" also, but you will use
### that two values on your own risk.
### They will be parsed into Linux Constants with leading 'B'.
### e.g.: export WKBAUDRATE="19200" (default)
###
export WKBAUDRATE="19200"

#
# LD_LIBRARY_PATH is the Linux default lookup path for Shared Objects
# please add a ':$LD_LIBRARY_PATH' on the end/front instead of overwrite
# this important path as shown below!!
#
export LD_LIBRARY_PATH=./include:$LD_LIBRARY_PATH

env|grep WK
env|grep LD_LIBRARY_PATH
#EOF 20020208 - mn

KONEC
torej to je vse kar lahko spreminjam. LD_LIBRARY_PATH mi tu nekak ni jasen. Kaj bi vi tukaj spremenili in kako je z dovoljenji za dostopanje do portov (omenjeno zgoraj v komentarju pri WKPORTNAME)
Se enkrat se opravicujem za dolg post in prosim za pomoc!

Pa ima kernel podporo za paralene naprave vklopljeno?
/sbin/lsmod mora pokazati parport_pc modul.

Default RH kernel ima lpt podporo itak že vključeno kot modul.

Ko stvar poženeš, ali se pojavi kako sporočilo, napaka?

Zadevo preizkusi še na kakem starejšem linuxu, ki je eksplicitno podprt, npr. RH7.2.

/dev/lp0 je za lpt1
/dev/lp1 je za lpt2
itd

Se strinjam s tabo, da je v tem fajlu eksplicitno navedena le podpora serijskemu in USB portu, kar tudi mene malo čudi. Windows ekvivalent ima podporo za vse mogoče porte.
Vendar pazi: tudi, če vklopim da išče po serijskih portih (/dev/ttyS), mi napiše enako: 0 ports scanned: 0 WIBU Boxes at 0 ports found.
Vsekakor bi moralo napisati vsaj: 1 ports scanned: 0 WIBU Boxes found

Dokler ne bom videl tega, mi ne bo dalo miru, saj je precej možnosti, da bo potem, ko bom to nastavitev spremenil na paralelni port, stvar začela delovati. Malo nelogično bi bilo, da ne bi, saj je večina teh donglov v preteklosti bila za LPT...

Ce je skripta napisana za serijske in usb porte, potem ti zelo verjetno ne bo delala s paralel porti... ;)

Mogoce ti ne najde serijskega porta, ker ni nalozen modul zanj? (serial)

Lahko probas narediti tudi nekaj v tem stilu:

# dmesg | grep ttyS
# dmesg | grep para

modprobe ppa javi "no such device".

Zakaj ppa?
