That's all about how the 32 address bits are being distributed between network address and host address. /18 means the most significant 18 bits designate the network part, and the remaining 14 bits the host part. 192.168.0.0/18 will give you 4 subnets with 16384 (= 2^14) addresses each:
For minimum 1000 devices you'll need 10 bits to accommodate 1024 addresses, so the internal /22 netmask comes in handy (32 bit - 22 bit = 10 bit addresses in each subnet). The 16 (= 2^4; 4 = 14 - 10) sub-subnet ranges are
, the 9th of which - depending how you count them, starting from 0 or 1 - is the network address 192.168.32.0 with the broadcast address 192.168.35.255 (hopefully, as my binary calculus has become somewhat rusty).
Before I even attempt this, is it possible to grep for a pattern, maybe a partial sentence like "go to page 3", assign that to a variable and then use awk or something to pull out the 3 and assign it to a variable? So first I would have
Gotopg = "go to page 3"
then
page = 3 (9 Replies)

zmq_inproc
ZMQ_INPROC(7) 0MQ Manual ZMQ_INPROC(7)NAME
zmq_inproc - 0MQ local in-process (inter-thread) communication transport
SYNOPSIS
The in-process transport passes messages via memory directly between threads sharing a single 0MQ context.
Note
No I/O threads are involved in passing messages using the inproc transport. Therefore, if you are using a 0MQ context for in-process
messaging only you can initialise the context with zero I/O threads. See zmq_init(3) for details.
ADDRESSING
A 0MQ address string consists of two parts as follows: transport://endpoint. The transport part specifies the underlying transport protocol
to use, and for the in-process transport shall be set to inproc. The meaning of the endpoint part for the in-process transport is defined
below.
Assigning a local address to a socket
When assigning a local address to a socket using zmq_bind() with the inproc transport, the endpoint shall be interpreted as an arbitrary
string identifying the name to create. The name must be unique within the 0MQ context associated with the socket and may be up to 256
characters in length. No other restrictions are placed on the format of the name.
Connecting a socket
When connecting a socket to a peer address using zmq_connect() with the inproc transport, the endpoint shall be interpreted as an arbitrary
string identifying the name to connect to. The name must have been previously created by assigning it to at least one socket within the
same 0MQ context as the socket being connected.
WIRE FORMAT
Not applicable.
EXAMPLES
Assigning a local address to a socket.
/* Assign the in-process name "#1" */
rc = zmq_bind(socket, "inproc://#1");
assert (rc == 0);
/* Assign the in-process name "my-endpoint" */
rc = zmq_bind(socket, "inproc://my-endpoint");
assert (rc == 0);
Connecting a socket.
/* Connect to the in-process name "#1" */
rc = zmq_connect(socket, "inproc://#1");
assert (rc == 0);
/* Connect to the in-process name "my-endpoint" */
rc = zmq_connect(socket, "inproc://my-endpoint");
assert (rc == 0);
