I compiled the kernel with TUN support as a module. when issueing hte following command: # modprobe tun it creates a device called tun in /dev/misc/net/ and a link called tun in /dev/net pointing to misc/net/tun. This is wrong and should be either ../misc/net/tun or /dev/misc/net/tun Reproducible: Always Steps to Reproduce: See detail description. Actual Results: the tundevice is not usable. After correcting it manually: ln -sf /dev/misc/net/tun /dev/net/tun it works correctly (used it with openvpn) Expected Results: link correctly the device when probing/inserting the module Gentoo Base System version 1.4.3.13 Portage 2.0.50-r3 (default-x86-2004.0, gcc-3.3.2, glibc-2.3.2-r9, 2.6.3-gentoo-r1) ================================================================= System uname: 2.6.3-gentoo-r1 i686 Pentium III (Coppermine) Autoconf: sys-devel/autoconf-2.58-r1 Automake: sys-devel/automake-1.8.3 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-O3 -march=pentium3 -pipe -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" COMPILER="gcc3" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.2/share/config /usr/kde/3/share/config /usr/lib/mozilla/defaults/pref /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O3 -march=pentium3 -pipe -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs ccache sandbox" GENTOO_MIRRORS="ftp://ftp.wh2.tu-dresden.de/pub/mirrors/gentoo http://sunsite.cnlab-switch.ch/mirror/gentoo/ ftp://sunsite.cnlab-switch.ch/mirror/gentoo/ ftp://ftp.solnet.ch/mirror/Gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="" SYNC="rsync://rsync.de.gentoo.org/gentoo-portage" USE="X alsa apm arts avi berkdb bonobo crypt cups dvd encode esd ethereal foomaticdb gdbm gif gnome gphoto2 gtk gtk2 gtkhtml guile icq imlib jabber jpeg libg++ libwww mad mikmod motif mpeg ncurses nls oggvorbis opengl oss pam pcmcia pdflib per perl png python quicktime readline samba sdl slang snd-cs46xx spell sse ssl svga tcpd truetype usb x86 xml2 xmms xv yahoo zlib"
where did you get the specs saying this is where this node should be? Are you using udev?
I just noticed that there is already a bug for this related with kernel 2.4. To know where tun device should be I looked docs of products using it (e.g. openvpn) explaining how to create it... but my problem is not the localizatio nof the device but the symlink pointing to nowhere.
udev does the correct thing for me: $ ls -l /dev/net/tun crw-rw---- 1 root root 10, 200 Feb 10 18:20 /dev/net/tun user never mentioned whether they use devfs or udev, so please re-open once you have
actually, see Bug 51467 this is fixed in cvs now for devfs
