J'ai besoin d'openvpn et le tun(7M) c'est pas vraiment ce que je pensais etre un device tun... Alors apres avoir joue avec tun(7M) pour constater que j'avais pas ce que je voulais, j'ai un peu cherche et voila vite fait un ptit resume...

D'abord un "tutorial" etape par etape pour l'installation d'OpenVPN avec OpenSolaris... bon ok faut un driver tuntap "externe", mais bon...

Ensuite on rencontre des tites merdes genre :

# make install
ld -64 -r -o tun tun.o
ld -64 -r -o tap tap.o
/usr/bin/ginstall -c -m 644 -o root -g root if_tun.h /usr/include/net 
/usr/bin/ginstall -c -m 644 -o root -g root tun /usr/kernel/drv/amd64
/usr/bin/ginstall -c -m 644 -o root -g root tap /usr/kernel/drv/amd64
/usr/bin/ginstall -c -m 644 -o root -g root tun.conf /usr/kernel/drv
/usr/bin/ginstall -c -m 644 -o root -g root tap.conf /usr/kernel/drv
/usr/sbin/rem_drv tun >/dev/null 2>&1
/usr/sbin/rem_drv tap >/dev/null 2>&1
/usr/sbin/add_drv tun   
devfsadm: driver failed to attach: tun
Warning: Driver (tun) successfully added to system but failed to attach
/usr/sbin/add_drv tap
devfsadm: driver failed to attach: tap
Warning: Driver (tap) successfully added to system but failed to attach

Bon hop hop on prends son cerveau, on tente de l'allumer (il est a peu pres minuit...).. apres etre passe par la, puis la...

j'ai finalement abouti ICI et la houra!

J'ai modifie qqes details dans le Makefile du driver Tun/Tap "externe" vite fait... Makefile:

[...]
CC = cc
LD = ld

DEFS = -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DTUN_VER=\"1.1\ 04/22/2009\"
CFLAGS = $(DEFS) -O2 -D_KERNEL -I. -m64 -xmodel=kernel

ADD_DRV = /usr/sbin/add_drv
REM_DRV = /usr/sbin/rem_drv
DRV_DIR = /usr/kernel/drv/amd64
DRV_CONF_DIR = /usr/kernel/drv
[...]

et on dit merci a -xmodel=kernel..

au passage je suis tombe sur ces deux choses aussi..

Et c'est apres m'etre pris la tete 20 minutes ( alors que je suis une grosse feignasse...) que je vois que qqun avait aussi resolu le 'blem ici

au final on finit par avoir:

youpi.

NB: j'utilise le compilo sun.
