Search IP Address in list of ranges -- not working great
I have been struggling with a script to automate some security related activities. I have it pretty much working, all except the search. I have an input file formatted as such:
This represents ranges of IP addresses that have been defined in a security appliance. I need to search this file to determine if the input variable (An single IP Address) falls within any of these ranges. If so display the line.
I am a a novice at development, and naively though this would be fairly straight-forward. It wasn't. However, after many false starts, I was able to get some fairly accurate (fuzzy) results by iteratively searching the first octect for an exact match>file, then using agrep -B to find the best match from there. My code:
This is not ideal, but works for now. I am new to programming -- surely there are folks out there that help me produce more exact results. Thanks in advance!
Hello,
Here is my problem. there are two files.

Hi people,
I have 2 files, one with a list of non consecutive ranges (File1.txt), where each range begins with the value in column 1
and finishes with the value in column 2 in the same line, as can be seen above.

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:

Howdy folks,
perhaps someone can help me with this problem. My knowledge of awk is not the best... but I've managed to a certain degree and now I'm stuck.
These are the steps and the format outputs, problem is written in red text after the STEP 2:

Hi All,
The developers want me to search and capture the weblogic log, you know this big logs of htmls.
They want to me to have ranges on the date and time. Like
from "2010-01-20 14:04:46,186" to "2010-01-20 15:00:12,490"
I can only do this,

I am a noob and need some help.
I am trying to find files created between a date range.
For Example:

netmasks
netmasks(4) File Formats netmasks(4)NAME
netmasks - network mask database
SYNOPSIS
/etc/inet/netmasks
/etc/netmasks
DESCRIPTION
The netmasks file contains network masks used to implement IP subnetting. It supports both standard subnetting as specified in RFC-950 and
variable length subnetting as specified in RFC-1519. When using standard subnetting there should be a single line for each network that is
subnetted in this file with the network number, any number of SPACE or TAB characters, and the network mask to use on that network. Network
numbers and masks may be specified in the conventional IP `.' (dot) notation (like IP host addresses, but with zeroes for the host part).
For example,
128.32.0.0 255.255.255.0
can be used to specify that the Class B network 128.32.0.0 should have eight bits of subnet field and eight bits of host field, in addition
to the standard sixteen bits in the network field.
When using variable length subnetting, the format is identical. However, there should be a line for each subnet with the first field being
the subnet and the second field being the netmask that applies to that subnet. The users of the database, such as ifconfig(1M), perform a
lookup to find the longest possible matching mask. It is possible to combine the RFC-950 and RFC-1519 form of subnet masks in the net-
masks file. For example,
128.32.0.0 255.255.255.0
128.32.27.0 255.255.255.240
128.32.27.16 255.255.255.240
128.32.27.32 255.255.255.240
128.32.27.48 255.255.255.240
128.32.27.64 255.255.255.240
128.32.27.80 255.255.255.240
128.32.27.96 255.255.255.240
128.32.27.112 255.255.255.240
128.32.27.128 255.255.255.240
128.32.27.144 255.255.255.240
128.32.27.160 255.255.255.240
128.32.27.176 255.255.255.240
128.32.27.192 255.255.255.240
128.32.27.208 255.255.255.240
128.32.27.224 255.255.255.240
128.32.27.240 255.255.255.240
128.32.64.0 255.255.255.192
can be used to specify different netmasks in different parts of the 128.32.0.0 Class B network number. Addresses 128.32.27.0 through
128.32.27.255 have a subnet mask with 28 bits in the combined network and subnet fields (often referred to as the subnet field) and 4 bits
in the host field. Furthermore, addresses 128.32.64.0 through 128.32.64.63 have a 26 bits in the subnet field. Finally, all other
addresses in the range 128.32.0.0 through 128.32.255.255 have a 24 bit subnet field.
Invalid entries are ignored.
