I need a great Password Generator program. I looked at a few of them, but none of them seemed to be what I wanted. So I have decided to write my own. (That's the cool thing about being a programmer....I always get what I want in software :) )
Do you have any password generators that you... (13 Replies)
I am trying to find a way to generate random numbers within a shell script.
Does Solaris have a utility that will generate random numbers?
Thanks in advance.

Hi,
I need to create a table with random sentences. I need lines that are upto 1000 characters in lenght. I need a random sentence generator that will create sentences and output it to a text file. The sentences should be of lenght varying from 1 to 1000.
Does anyone know how this can be... (7 Replies)
I've got a file (numbers.txt) filled with numbers and I want to replace each one of those numbers with a new random number between 0 and 9. This is my script so far:
#!/bin/bash
rand=$(($RANDOM % 9))
sed -i s//$rand/g numbers.txtThe problem that I have is that it replaces each number with just... (2 Replies)
Hi,
I need a script that will generate a set of random strings in sequence, with the ability to predetermine the length, quantity, and alphabet of individual string, and to use the outputs of earlier strings in the sequence to define the parameters of later strings. For examples, I might want... (5 Replies)

Here is my new password generation script. The attachment, swordfish.txt, is in dos format. Remember that you need to use dos2unix or flip or something to get it into unix format.
The script is self documenting. It has an extensive help system built-in. And you can run:

There was an upload recently on generating a pseudo-random file when /dev/random does NOT exist.
This does not need /dev/random, /dev/urandom or $RANDOM either...
(I assume $RANDOM relies on the /dev/random device in some way.)
This code uses hexdump just because I like hexdump for ease of... (2 Replies)
Dear UNIX Friends,
I was wondering if there is a random RGB color generator or any function in any unix platforms.
Please share your ideas.

IPSEC_RANBITS(8) [FIXME: manual] IPSEC_RANBITS(8)NAME
ipsec_ranbits - generate random bits in ASCII form
SYNOPSIS
ipsec ranbits [--quick] [--continuous] [--bytes] nbits
DESCRIPTION
Ranbits obtains nbits (rounded up to the nearest byte) high-quality random bits from random(4), and emits them on standard output as an
ASCII string. The default output format is datatot(3) h format: lowercase hexadecimal with a 0x prefix and an underscore every 32 bits.
The --quick option produces quick-and-dirty random bits: instead of using the high-quality random bits from /dev/random, which may take
some time to supply the necessary bits if nbits is large, ranbits uses /dev/urandom, which yields prompt results but lower-quality
randomness.
The --continuous option uses datatot(3) x output format, like h but without the underscores.
The --bytes option causes nbits to be interpreted as a byte count rather than a bit count.
FILES
/dev/random, /dev/urandom

Written for the Linux FreeS/WAN project <http://www.freeswan.org> by Henry Spencer.
BUGS
There is an internal limit on nbits, currently 20000.
Without --quick, ranbits's run time is difficult to predict. A request for a large number of bits, at a time when the system's entropy pool
is low on randomness, may take quite a while to satisfy.
Though not a bug of ranbits, the direct use of /dev/hw_random, the Linux hardware random number generator is not supported because it can
produce very non-random data. To properly use /dev/hw_random, the rngd daemon should be used to read from /dev/hw_random and write to
/dev/random, while performing a FIPS test on the hardware random read. No changes to Openswan are required for this support - just a
running rngd.
