Hello, I don't know if this is a bug, but I haven't found any information about that problem. My ISP does a disconnect after 24h. The problem I have is that if this happens some other processes are killed by signal 15. As an example: dnsmasq, openvpn, noip2, bacula storage daemon, cvsd, sshd and much more see the appended log. The question is, why this happens and how to turn it off. One problem of this situation is that on every disconnect the tape of my tape drive was re-wounded. Thank you for your advise Greetings ==== emerge --info mrb ~ # emerge --info Portage 2.1.6.7 (default/linux/amd64/2008.0, gcc-4.3.3, glibc-2.9_p20081201-r1, 2.6.27-gentoo-r5 x86_64) ================================================================= System uname: Linux-2.6.27-gentoo-r5-x86_64-Intel-R-_Core-TM-2_Quad_CPU_@_2.40GHz-with-glibc2.2.5 Timestamp of tree: Fri, 06 Feb 2009 15:10:03 +0000 app-shells/bash: 3.2_p48 dev-java/java-config: 1.3.7-r1, 2.1.7 dev-lang/python: 2.5.4-r2 dev-util/cmake: 2.6.2 sys-apps/baselayout: 2.0.0 sys-apps/openrc: 0.4.2 sys-apps/sandbox: 1.3.2 sys-devel/autoconf: 2.13, 2.63 sys-devel/automake: 1.5, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.2 sys-devel/binutils: 2.19.50.0.1 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.6a virtual/os-headers: 2.6.28-r1 ACCEPT_KEYWORDS="amd64 ~amd64" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=native -O2 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/config /var/lib/hsqldb" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c /etc/udev/rules.d" CXXFLAGS="-march=native -O2 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="distlocks fixpackages parallel-fetch protect-owned sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS="http://ftp.romnet.org/gentoo/ http://mirror.ovh.net/gentoo-distfiles/ http://linux.rz.ruhr-uni-bochum.de/download/gentoo-mirror/" LDFLAGS="-Wl,-O1" LINGUAS="de" MAKEOPTS="-j5" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X Xaw3d a52 aac acl alsa amd64 amr arts automount avahi bash-completion berkdb bitmap-fonts bzip2 cdr cli cracklib crypt cups dbus desktop dhcp dri dts dv dvb dvd dvdr dvdread encode esd fax firefox flac font-server fortran gcj gdbm gif glib gphoto2 gpm graphviz gtk hal howl iconv ieee1394 imagemagick imlib ipv6 isdnlog jack java jpeg jpeg2k kde kpathsea ldap lesstif libcaca lmsensors midi mmx motif mozbranding mp3 mpeg mudflap multilib ncurses neXt network nls nptl nptlonly nsplugin nvidia oav ogg opengl openmp oss pam pch pcre perl png pppd python qt qt3 qt3support qt4 readline reflection samba scanner sdl session slp soundex speex spell spl sse sse2 ssl sysfs syslog tcl tcpd tetex theora threads tiff tk toolbar truetype truetype-fonts type1 type1-fonts unicode urandom v4l vcd vdr vorbis wavpack wifi winbind xine xinerama xml xorg xscreensaver xulrunner xv xvid zlib" ALSA_CARDS="hda-intel" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic auth_digest authn_anon authn_dbd authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock dbd deflate dir disk_cache env expires ext_filter file_cache filter headers ident imagemap include info log_config logio mem_cache mime mime_magic negotiation proxy proxy_ajp proxy_balancer proxy_connect proxy_http rewrite setenvif so speling status unique_id userdir usertrack vhost_alias" CAMERAS="canon" ELIBC="glibc" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="de" USERLAND="GNU" VIDEO_CARDS="nv nvidia" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, LANG, LC_ALL, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY === emerge mrb ~ # emerge -pv openrc ppp These are the packages that would be merged, in order: Calculating dependencies... done!

I forgot to say not every time all processes came back. So it could happen that I loose ssh.
Ok I found the solution. Sorry for the inconvenience. The solution was to add the following to lines into /etc/conf.d/net: rc_net_br0_after="net.ppp0" # for starting the main network interface after internet connection. This avoids that ntp_client can not synchronize time in lack of the missing connection rc_net_ppp0_provide="!net" # Say that net.ppp0 not provides direct net services. rc_net_vpn0_provide="!net" #This setting have also done for the vpn0 device.
