I am trying to set up a usb gsm Modem. I can't find /etc/sysconfig/networking/devices/ directory to put the driver configuration file into.

In Ubuntu where can i find this directory? I want to put /etc/sysconfig/networking/devices/ifcfg-Verizon_USB file wherever it needs to go.

The contents are:

ONBOOT=no
USERCTL=yes
PEERDNS=yes
TYPE=Modem
DEVICE=ppp0
BOOTPROTO=dialup
CCP=on
PC=on
AC=on
BSDCOMP=on
VJ=on
VJCCOMP=on
LINESPEED=115200
MODEMPORT=/dev/cellphone
PROVIDER=VerizonQNC
DEFROUTE=yes
PERSIST=no
PAPNAME=qnc
WVDIALSECT=Verizon_USB
MODEMNAME=Modem_USB
DEMAND=no

This is an area where the Debian and Red Hat families really differ. Network interfaces in Debian/Ubuntu are not defined by files in /etc/sysconfig/network-scripts (as you have noticed, there isn't even a /etc/sysconfig directory), but by /etc/network/interfaces. To learn more, check out the manpage online or run man interfaces on your Debian/Ubuntu system.

  • In the man page do I find where to put driver configuration file?

  • Yes. There is no separate driver configuration file. All network interface settings supported by Debian are configured in the interfaces file, in the iface statement of that interface.

  • Your ifcfg-Verizon_USB is in a Red Hat-specific format, you need to convert its meaning into the Debian-specific format.

  • Its been a year since i asked this question. Now I'm using wvdial to connect GSM modem. N to be frank i forgot the need why i asked this question. I think setting above configuration will connect my modem through network manager. I'll try it some other tym. Thank you.

  • Yeah, answering mostly for the benefit of someone who might find this question and have the same trouble. I figured you must have solved it by now. :-)

/etc/sysconfig/network-scripts, doesnt exist on _buntus. It is under /etc/NetworkManager/system-connections as 'team-slave-enp0s25.nmconnection' for example, because it uses the newer nmcli and network-manager.
