UMBCTL(8) System Manager's Manual UMBCTL(8) NAME umbctl - display or set parameters for a MBIM interface (4G/LTE) SYNOPSIS umbctl [-v] ifname [parameter[=value]] [...] umbctl [-v] [-f config-file] ifname [parameter[=value]] [...] 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 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.
