NAME
hsolinkcontrol - application helper to manage the Option hso interface
SYNOPSIS
hsolinkcontrol [down port_num | up port_num dns1 dns2 ip ]
DESCRIPTION
hsolinkcontrol manages the hso IP link on behalf of connection manager
programs; handling the low level tasks of bringing up the link and
tearing it down again. hsolinkcontrol controls the update of the
routing table, resolv.conf and calls ifconfig for hso?.
If resolvconf(8)
is installed it will use that program instead of directly manipulating
/etc/resolv.conf.
OPTIONS
down port_num
Bring down hso[port_num] link. If resolvconf was used then also
delete hso[port_num] from routing table. E.g. hsolinkcontrol
down 0 Which brings down the hso[port_num] link if it exists.
up port_num dns1 dns2 ip
Start up hso[port_num] link, calling ifconfig then updating the
routing table and /etc/resolv.conf. By the time hsolinkcontrol
is called by a connection manager application the network PDP
context has already been defined and started. E.g.
hsolinkcontrol up 1
unbind driver end-point
Where driver is typically the directory
"/sys/bus/usb/drivers/hso/" and end-point is one of those listed
in the directory. The purpose is to disconnect the driver from
the end point. This may help unblock the driver (not sure if
this is required).
bind driver end-point
Where driver is typically the directory
"/sys/bus/usb/drivers/hso/" and end-point is one of those listed
in the directory. The purpose is to re-assign the driver to the
end point following a corresponding unbind.
FILES
If hsolinkcontrol directly manages the /etc/resolv.conf file then it
will create /etc/resolv.conf.hsoc.tmp to hold the old copy of
/etc/resolv.conf which is restored when the link is brought down.
ENVIRONMENT
None
DIAGNOSTICS
Calling the program without parameters makes it report if resolvconf
is present.
NOTES
None
BUGS
No validation done on parameters.
