Trying to do a ksh script that needs to list all ip address between ip address a and b ..
ie.
Ip address A=192.168.1.200
Ip address B=192.168.2.15
So the subnet changes from 1 to 2 but I want to list all possible ip addresses between the 2..
Which would be:

Hi there
I lost connectivity to one of our remote systems and when I checked the messages log I found the following:

four interfaces with ifconfig
all interfaces have the same mac. If is not set for unique.
but it still works.
what difference does it make to have all macs the same or different? (4 Replies)

securenets - NIS map security file
DESCRIPTION
The file defines networks and hosts that can access the NIS maps on a server. Each line in the file gives a network mask and a net
address. For example:
The format of the file is as follows:
o Lines beginning with the character are treated as comments.
o Lines that are not comment lines contain two fields separated by white space. The first field is a netmask, and the second field is a
network.
o The netmask field can be one of the following:
o 255.255.255.255 (IPv4)
o ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff (IPv6)
o the string indicating that the second field is a specific host to be allowed access.
The file can have any number of netmask/net pairs.
When is started on the server, it checks for the existence of and reads its contents into memory if it exists. must be stopped and
restarted for any changes in to take effect.
Upon startup, the netmask and the net address are converted to binary format and logical ANDed. The result must equal the net address (the
second address) to be legal.
If the netmask is 255.255.255.255 (all 1's in binary), any address in the net address argument will match it. If any field in the netmask
is 0, the corresponding field in the net address must be 0. When used in this way, the portion of the addresses given as 0 acts as a wild
card.
When a client attempts to bind to the server, checks the client's IP against those given in the file. Again, the address is converted to
binary and logical ANDed with the netmask. The result must equal the net address given in the file. If the client address does not match
any pairs in the file, the binding is refused with the message, "no such map in server's NIS domain".
The file can be used to limit access to specific hosts or to subnets using the wildcard capability.
If there are syntax errors in the file, messages are logged to the logging file (default and is not started.
If a host has multiple interfaces, each interface address must be allowed in the securenets file for that host to have reliable NIS access.
EXAMPLES
The following examples show entries for the file.
Either of the following entries provides access only to the host with address 192.33.33.33:
or
The following entry allows access by any host on the 192.33.33 subnet:
For broader access, such as an entire enterprise, the following entry allows any host whose address begins with "15" to be served:
Either of the following entries allows access for an individual IPv6 address:
or
The following entry allows access for all IPv6 addresses starting with "fec0":
