6.2.3. Working With the CTC Device Driver
A Channel-to-Channel (CTC) connection is the typical high speed connection between
mainframes. The CTC device driver can be used to establish a point-to-point TCP/IP or tty
connection between two Linux for zSeries and S/390 instances or between a Linux for zSeries
and S/390 instance and another mainframe operating system instance such as z/OS, OS/390,
z/VM, or z/VSE.
The CTC driver assigns a base interface name like the following:
ctc<n>
The value
<n>
is an integer that uniquely identifies the device.
<n>
is 0 for the first device of that
type, 1 for the second, and so on.
• Load the device driver:
# modprobe ctc
• Create the group device:
# echo <read_device_bus_id>,<write_device_bus_id> >
/sys/bus/ccwgroup/drivers/ctc/group
Due to the length of this command, it has been broken into two lines.
• Configure the device.
Set the protocol:
# echo <protocol> /sys/bus/ccwgroup/drivers/ctc/<device_bus_id>/protocol
