I have moduleless solid kernel: hardned-sources-3.9.9. All ipv6 options are compiled in. I have sys-apps/openrc-0.11.8 and sys-apps/iproute2-3.8.0. I have four valid external ipv4 attached to eth0. When I use such configuration in /etc/conf.d/net (or if I change "ipv6tun" to "6to4" exactly as in example renaming net.ipv6tun to net.6to4): link_ipv6tun="eth0" config_ipv6tun="ip6to4" rc_net_ipv6tun_need="net.eth0 I get such error rc-service net.ipv6tun start * Caching service dependencies ... [ ok ] * Bringing up interface ipv6tun * Creating 6to4 tunnel on ipv6tun ... add tunnel "sit0" failed: No buffer space available [ !! ] * ERROR: net.ipv6tun failed to start If I change ipv6tun to sit0 (renaming net.ipv6tun and changing config strings) I get (I've masked my ips, they all are translated from my ipv4-adresses correctly): * Bringing up interface sit0 * ip6to4 ... [ ok ] * 2002:XXXX:YYYY::1/48 ... * Unknown argument to config_sit0: 2002:ZZZZ:TTTT::1/48 * Unknown argument to config_sit0: 2002:QQQQ:WWWW::1/48 * Unknown argument to config_sit0: 2002:OOOO:PPPP::1/48 [ ok ] * Adding routes * 2003::/3 via ::192.88.99.1 metric 2147483647 ... I don't know whether it's one bug or more. emerge --info: Portage 2.1.12.2 (hardened/linux/x86, gcc-4.6.3, glibc-2.15-r3, 3.9.9-hardened i686) ================================================================= System uname: Linux-3.9.9-hardened-i686-Intel-R-_Core-TM-2_Quad_CPU_Q9550_@_2.83GHz-with-gentoo-2.2 KiB Mem: 252996 total, 11180 free KiB Swap: 524284 total, 522888 free Timestamp of tree: Mon, 29 Jul 2013 10:15:01 +0000 ld GNU ld (GNU Binutils) 2.23.1 app-shells/bash: 4.2_p45 dev-lang/python: 2.7.5 sys-apps/baselayout: 2.2 sys-apps/openrc: 0.11.8 sys-apps/sandbox: 2.6-r1 sys-devel/binutils: 2.23.1 sys-devel/gcc: 4.6.3 sys-devel/gcc-config: 1.7.3 sys-devel/libtool: 2.4-r1 sys-devel/make: 3.82-r4 sys-kernel/linux-headers: 3.7 (virtual/os-headers) sys-libs/glibc: 2.15-r3 Repositories: gentoo x-mylay ACCEPT_KEYWORDS="x86" ACCEPT_LICENSE="* -@EULA" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=native -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/php/apache2-php5.4/ext-active/ /etc/php/cgi-php5.4/ext-active/ /etc/php/cli-php5.4/ext-active/ /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo" CXXFLAGS="-O2 -march=native -pipe" DISTDIR="/tmp/portage" EMERGE_DEFAULT_OPTS="--autounmask=n" FCFLAGS="-march=i686 -O2 -pipe" FEATURES="assume-digests binpkg-logs config-protect-if-modified distlocks ebuild-locks fixlafiles merge-sync news nodoc noinfo noman parallel-fetch preserve-libs protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync xattr" FFLAGS="-march=i686 -O2 -pipe" GENTOO_MIRRORS="ftp://gentoo.bloodhost.ru/" LANG="ru_RU.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" PKGDIR="/tmp/portage" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_EXTRA_OPTS="--exclude-from=/etc/portage/exclude-from-sync --delete-excluded" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --human-readable --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/var/portage/mylay" SYNC="rsync://gentoo.bloodhost.ru/gentoo-portage" USE="acl bzip2 cli cracklib crypt cxx dri gnutls hardened iconv icu idn ipv6 modules mudflap mysql mysqli ncurses nls nptl openmp pam pax_kernel pcre pic readline session ssl symlink threads tls unicode urandom vhosts x86 xml zlib" ABI_X86="32" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1 emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" APACHE2_MODULES="authn_core authz_core socache_shmcb unixd actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" CALLIGRA_FEATURES="kexi words flow plan sheets stage tables krita karbon braindump author" CAMERAS="ptp2" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ubx" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer" LINGUAS="ru en" NGINX_MODULES_HTTP="access auth_basic autoindex browser charset empty_gif fastcgi geo limit_req map referer rewrite spdy split_clients userid" OFFICE_IMPLEMENTATION="libreoffice" PHP_TARGETS="php5-4" PYTHON_SINGLE_TARGET="python2_7" PYTHON_TARGETS="python2_7" RUBY_TARGETS="ruby19 ruby18" USERLAND="GNU" VIDEO_CARDS="apm ark chips cirrus cyrix dummy fbdev glint i128 i740 intel mach64 mga nsc nv r128 radeon rendition s3 s3virge savage siliconmotion sis sisusb tdfx tga trident tseng v4l vesa via vmware nouveau" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, INSTALL_MASK, LC_ALL, MAKEOPTS, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, USE_PYTHON
