Hi, I'm new to unix and have absolutely no experience with it. I am trying to change the network setting on the only computer on our network with SCO Unix. We switched ISP's and now have a new set of IP's. I can't for the life of me figure out how to go in and change these settings, please help.... (12 Replies)
I am trying to find out if you can create an ACL for telnet sessions and restrict it to a certain subnet/IP range..
any information or where to look would be greatly appreciated.

Hmmm, tough question for me, so I put it here.
I am trying to use shell script or mysql to do the following thing.
tableA, in which all are single ips.

and tableB, a list of our group subnets.

Hi,
We have an app specific legacy environment running SCO Openserver 5.0.7. I need to be able to (1) scan a pre-existing “form” consisting of logo/boxes/lines/static text as an image , (2) lay a print file from the app "on top of the image" and (3) output the "merge" as a PDF file.

Is there a command that can lookup ip address, subnet mask, gateway, and dns all at the same. I know ifconfig can lookup ip address and subnet mask. I know route -n can lookup gateway. Not sure about a dns command. So I hope there is a way to lookup ip address, subnet mask, gateway, and dns all at... (2 Replies)
I currently have a text file which looks like this
2010.26 (0.0306746) @ 59,19
I want to remove all 22 characters up till the "59"
NOTE: REMOVE, not replace with (null)
NOTE2: The 59 CANNOT be taken as a number to consider in the script... it is not fixed. The only thing that is fixed is... (2 Replies)
I have this subnet file shown below. How can I calculate all ip addresses from that list
103.22.200.0/22

Hi my problem is that I need to send a form to a web address using curl, from a unix shell, the web address on the receiving end will only accept incoming data from a specific ip address, and port, on another machine on our intranet, and I can not run curl on that machine. Is there any way I... (5 Replies)

bup-margin
bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
