Alpine Linux

link?

Here it is: http://www.openl2tp.org/

This package is tricky. It seems to trigger a bug in rpcgen:

...
make -C cli - --jobserver-fds=3,4 -j EXTRA_CFLAGS="  -DL2TP_ASYNC_RPC" 
stack smashing detected: rpcgen terminated()
make: *** [l2tp_rpc_server.c] Abortedd()
...

Here is what i got so far, in case someone feels to work on this:

pkgname=openl2tp
pkgver=1.7
pkgrel=0
pkgdesc="l2tp plugin for pppd" 
url="http://www.openl2tp.org" 
license="GPL" 
depends=
makedepends="rpcgen linux-grsec-dev flex bison ppp-dev" 
install=
subpackages="$pkgname-dev $pkgname-doc" 
source="ftp://ftp.openl2tp.org/releases/openl2tp-$pkgver/openl2tp-$pkgver.tar.gz" 

_builddir="$srcdir"/$pkgname-$pkgver

prepare() {
        cd "$_builddir" 
        # apply patches here
}

build() {
        cd "$_builddir" 
        local _kabiver=$(cat /usr/share/kernel/grsec/kernel.release)
        local _ksrc=/usr/src/linux-headers-$_kabiver
        make RPCGENFLAGS="-N -C -L" \
                KERNEL_BLDDIR=$_ksrc \
                KERNEL_SRCDIR=$_ksrc \
                || return 1
}

package() {
        cd "$_builddir" 
        make DESTDIR="$pkgdir" install

        # remove the 2 lines below (and this) if there is no init.d script
        # install -m755 -D "$srcdir"/$pkgname.initd "$pkgdir"/etc/init.d/$pkgname
        # install -m644 -D "$srcdir"/$pkgname.confd "$pkgdir"/etc/conf.d/$pkgname
}

Other options to greate vpns are openvpn and opennhrp+ipsec-tools.

I am using xl2tpd, which works fine in Alpine.
