I need help. I have a cable modem. It has an USB out. I didn't want to buy a router. So I hooked my WinXP computer up to the cable modem by USB. I wanted to network my Linux computer to the WinXp computer by the ethernet cards in each. The only problem is, I don't know what I need to know to do... (1 Reply)
Whats up All!
Im fairly new to unix and i have a question. I was looking at my ifconfig -a on my server and my prompt, which was just my hostname, sudenly changed to one of my network interfaces(ge0). Does anyone know how to change that back? Also when i type in the hostname command it spits out... (4 Replies)
I have a question concerning default gateways in RHEL. In Linux, the default gateway does not have to be associated with a specific interface - when you look at your routing table with route -n, your default gateway can be associated with the default route on the last line, and doesn't have to be...

Hii,
Today morning I attended an interview, they had showed me the attached image and had few questions about that.
The image shows a network with 4 nodes viz.. A B C & D and two switches(layer2) and a router(layer3). Just wanted to know can node A and node D would be on same network e.g... (4 Replies)
Hi All,
Here is the problem: I have done a c++ code in Visual Studio 2010, it's a simple project that only have one main function which takes 2 parameters: an integer and a file that stores data. Now, I am asked to write a shell script in linux to execute my main function. I asked my professor... (1 Reply)
Cheers!
In /etc/syslog.conf, if an error type is not specified, is it logged anywhere (most preferable is it logged to /var/log/messages) or not?
To be more precise I am interested in error and critical level messages. At default these errors are not specified in syslog.conf, and I need to... (6 Replies)
This is a screenshot from "cockpit", a nice app of Fedora server,I can see from it disk,network,ram usage for host.

The good thing is start preconfigured for host.
My question is..someone know a app like this which can monitor a entire... (0 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.
915 of 1612581 (0.057%)
