===== 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 addr add XXX.XXX.XXX.XXX/32 dev wwan0
ip route add default dev wwan0 metric 200

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