===== instalace debianu headless ===== - napriklad na webu FAI vygenerujeme instalacni img - vypalime na instalacni medium - vlozime img do ciloveho stroje, kde je cilove medium - cekame minimalne 20min - rebootneme do nainstalovaneho systemu ===== modem a ppp pres operatora ===== <code bash>apt install wvdial</code> <code bash>nano /etc/wvdial.conf</code> <file conf wvdial.conf> [Dialer Defaults] Modem = /dev/ttyUSB2 Modem Type = Analog Modem ISDN*= 0 Baud = 460800 Dial Attempts = 1 Username = o2 Password = o2 Init1 = ATZ Init2 = AT&F &D2 &C1 Init3 = ATS7=60 S30=0 S0=0 Init4 = AT+CGDCONT=1,„IP“,„internet“ Phone = *99# Stupid Mode = 1 </file> vyzkousime wvdial pak do /etc/network/interfaces jako prvni <code>auto ppp0 iface ppp0 inet wvdial</code> a reboot, default routa by mela jit pres ppp0

Uz nepouzivame vwdial, novejsi karty maji QMI. Inicializace modemu a pripojeni

mmcli --modem=0 --enable
mmcli -m 0 --simple-connect='apn=XXXX,ip-type=ipv4'
mmcli -m 0 --bearer=0

status overime

mmcli -m 0

pokud je pripojeno, zjistime IP interfacu a pridame ji wwan0

ip link set wwan0 up
ip link set dev wwan0 mtu 1500
ip link set dev wwan0 arp off
ip route add default dev wwan0 metric 200

potrebujeme xl2tp: upravit /etc/xl2tpd/xl2tpd.conf
