NAME

umbctl — display or set MBIM cellular modem interface parameters (4G/LTE)

SYNOPSIS

DESCRIPTION

umbctl supports the following options:

-f config-file

Parse config-file for parameter[=value] pairs, one per line, as if they had been specified on the command line. This allows the password or PIN codes to be not passed as command line arguments. Comments starting with # to the end of the current line are ignored.

-v

Enables verbose mode.

The umb(4) driver may require a number of additional arguments or optional parameters besides the settings that can be adjusted with ifconfig(8). These may be credentials or other tunable connectivity variables. The umbctl utility can be used to display the current settings, or to adjust these parameters as required.

For whatever intent umbctl is being called, at least the parameter ifname needs to be specified, naming the interface for which the settings are to be performed or displayed. Use ifconfig(8) or netstat(1) to see which interfaces are available.

If no other parameter is given, umbctl will just list the current status for ifname and exit.

If any additional parameter is supplied, superuser privileges are required, and the command works in ‘set’ mode. This is normally done quietly, unless the option -v is also enabled, which will cause a final printout of the status as described above once all other actions have been taken.

The parameters currently supported include:

apn=access-point

Set the APN to access-point.

username=username

Set the username to username.

password=password

Set the password to password.

pin=pin-code

Enter the PIN pin-code.

puk=puk-code

Enter the PUK puk-code.

roaming

Allow data connections when roaming.

-roaming

Deny data connections when roaming.

EXAMPLES

Display the settings for umb0:

# umbctl umb0
umb0: state up, mode automatic, registration home network
	provider "BSD-Net", dataclass LTE, signal good
	phone number "+15554242", roaming "" (denied)
	APN "", TX 50000000, RX 100000000
	firmware "MBIM_FW_V1.0", hardware "MBIM_HW_V1.0"

Configure the connection parameters for umb0 from the command line:

# umbctl umb0 apn operator.internet username mobile password mobile

Configure the connection parameters for umb0 from a file:

# umbctl -f /dev/stdin umb0 << EOF
pin=1234
EOF
