That causes DNS resolving to break. So I know there are several things I can use as workaround like using resolvconf or disable the domain-name-servers request in the dhclient.conf. I am using Debian stable with ppp version 2.4.4rel-10.1 But I would like to see what the experts think what causes these issues and what would be the best solution? This system connection should try to stay persistent connected no matter what. Thanks in advance, Jelle I included my setup below: ------------------------------------------------------------------------ echo "vodafone * vodafone" | sudo tee /etc/ppp/pap-secrets echo "vodafone * vodafone" | sudo tee /etc/ppp/chap-secrets ------------------------------------------------------------------------ echo 'TIMEOUT 3 ABORT "BUSY" ABORT "NO CARRIER" ABORT "VOICE" ABORT "NO DIALTONE" ABORT "NO DIAL TONE" ABORT "NO ANSWER" ABORT DELAYED "" ATZ OK ATQ0&FEV1X1S0=0&C1&D2 OK AT+CGDCONT,"IP","office.vodafone.nl" OK ATDT*99***16# CONNECT ""' | sudo tee /etc/chatscripts/mobile-vodafone.chat echo '/dev/ttyUSB0 7200000 user vodafone connect "/usr/sbin/chat -v -f /etc/chatscripts/mobile-vodafone.chat" #crtscts #modem #noccp #nobsdcomp #novj #lock #hide-password noauth usepeerdns noipdefault #mtu 1492 mtu 1412 persist maxfail 0 holdoff 20 defaultroute replacedefaultroute' | sudo tee /etc/ppp/peers/mobile-vodafone ------------------------------------------------------------------------ cat /etc/network/interfaces auto lo iface lo inet loopback auto ppp0 iface ppp0 inet ppp provider mobile-vodafone ------------------------------------------------------------------------
