Programming :: Shutdown Multiple Computers Via SSH (Try Different Passwords)
Oct 1, 2010I'm trying to write a mass reboot script in the event of a power outage (servers go to UPS for some 15 minutes or so and shutdown uncleanly). What I have is a set of 6 common passwords which will be prompted for per ssh connection, is there any way I can cycle through this password list
Code:
#below is an example of how this is constructed, IP's are used instead of hostnames due to the possibility of a DNS server being offline.
SERVERSRM1="1 2 3"
SERVERSRM2="110 120 130"
For i in $SERVERSRM1; do ssh -n root@192.168.0.$i "hostname && shutdown -y -i5 -g0"; done;'
for i in $SERVERSRM2; do ssh -n root@192.168.0.$i "hostname && shutdown -y -i5 -g0"; done;'
Each time the code is executed I'm prompted for a password (it's always one of 6 passwords). It would be quicker to have the passwords be cycled through.
I realise this is basic code at the moment but it will eventually allow for a specific set of computers to be shut down based on what power supply they're using. Authorized keys not really an option given the scale of computers (some 300 or so).

Mar 12, 2009I'm making script for automated compiling of one program which would output builds optimized for many architectures. For clearancy, I do each build in it's own catalogue and list of builds with their respective catalogues would be stored as array. I'm using this guide as reference. It describes making array as naming a variable with additional brackets denoting it's position in array.
In my code, it looks exactly like this:
Code:
mtune[1]="build/mtune/athlon"
mtune[2]="build/mtune/athlon-4"
mtune[3]="build/mtune/athlon-mp"
[code]....
But upon invoking $mtune or any $mtune[x] variable, output is blank, like the variable(s) were never initialized. What am I doing wrong?

Mar 9, 2010[URL] Essentially, this module can be fine-tuned to the user's liking, using four integers instead of a boolean. By allowing for the red, green, blue, and alpha values to be fine-tuned, the user can control how transparent or opaque their desktop is. And how is this possible? C++ instead of C. How do you guys think of being able to customize RGBA?

Programming :: C++ - Initializing Static Member Array?
Jun 7, 2011The code below defines an array of structures in a class. I would like this to be a Static array and then initialize the array in a initialization method. I understand that initialization lists are the way to go but due to the size and complexity of the array I plan on using (the example below is a simple snippet that illustrates the problem) I would like to use the initialization method. However, I cant even get this thing to compile. The error says the reference to the ArrayOfStructs in the initialization routine is undefined.

P.S. This is the error message

Programming :: Declaration A Variable In One File And Initializing In Another?
Nov 25, 2010I made 2 files which are different from the program above one is temp1.h and another is temp2.c to understand how extern is used. So here is temp1.h
Code:
#include<stdlib.h>
typedef struct node * bond;
extern int jk;
and temp2.c is
Code:
#include<stdio.h>
#include<temp1.h>
struct node {
int data;
[code]...
I had declared jk in temp1.h as an extern int so why can I not initialize it in temp2.c?
Programming :: Initializing The SS Register (Intel Architecture)?
Jul 9, 2011Kernel 2.6.21.5, slackware 12.0 as 2.17 [I am speaking here about 80x86 processors, with their segment registers SS, DS, CS, ES.] In a source file for as, I wrote
Code:
.section _STACK
.rept 4096
.word 0
.endr
Now, in the .text section, I want to initialize SS, the stack segment, to point to the _STACK section. In other assemblers, there was a special section for the stack, and the linker cared about initializing SS. Here I use a common section for the stack. For a segment such as DS, I could write
mov ax,_DATA
mov ds,ax
But I don't think mov ax,_STACK would do with as/ls.how do I initialize SS?

View 2 Replies View RelatedServer :: SSH On Multiple Computers In Same Network
Dec 29, 2010I am setting up my home network. Currently, I have one computer (Munchen) which I have set in my router to receive SSH requests. This works just fine; I can SSH into that box from anywhere. I just put together a new computer, which I want to be a file repository, my ftp server, my http server, etc. What I would like is to be able to SSH into that machine from anywhere, then SSH into the other computers on that network from there.
Here is where I really don't understand the concept of what is going on. I can SSH past the router into one computer just fine either from anywhere (that makes sense to me). I can SSH from my new computer (Chemnitz) into Munchen (which is where the router points to and is running sshd) by using its local IP address, but I can't go from Munchen to Chemnitz (even though the server is running and the firewall should be allowing the connection). [URL]
Details of the system setup are below.
Munchen (receives all port 22 requests now)
Ubuntu 10.04
Chemnitz (I want to receive all port 22 requests and SSH into other computers on the network from it. Ultimately it will be a file sharing box, hosting a webpage, running an ftp server, etc.)

View 2 Replies View RelatedUbuntu Multimedia :: Pulseaudio Server On Multiple Computers In Local Network?
Dec 5, 2010I will cut to the chase. I am running three ubuntu computers on my local network:my desktop which runs ethernet, and two laptops which run wireless on the same network, and all from the same router. For purpose of this thread, I am concentrating on this one issue with pulse(assuming its pulse doing this). When I have two computers running at the same time, or even all three, I can hear bursts of sound coming from the other computer, not all the time, but consistently. I don't know what is causing this. I've searched hi and low in all ubuntu pulse audio forums and those mentioning pulseaudio and I have not seen this issue posted anywhere. Most threads deal with issues of not being able to get pulse to recognise audio from one computer to the other...mine is just the opposite...I'M TRYING TO STOP THIS FROM HAPPENING!...... If I'm listening to my music on my desktop, I don't want to hear what my son is playing on his laptop...and vice versa. all the computers at my home are running lucid lynx, latest updates and latest approved kernel as of the date of this post. 2.6.32-26-generic.

View 7 Replies View RelatedUbuntu Servers :: Provide Internet Access To Multiple Computers Using Only A Hub And 1 Ethernet Port
Mar 18, 2010Ever need to provide access to multiple PC's and did not have a router only a hub. Maybe this isn't original thinking, but then again maybe you didn't think of doing it this way (which i am sure there are many ways to do it) So I have 2 Ubuntu Servers, 1 Windows Box and a Hub - All 3 with internet access off of single ip and single Ethernet port.
While searching for a backup method today I came across Clonezilla. I was wondering if this was the right thing for me and since I needed to backup my roommates PC for a reformat and install of Windows I decided I would give it a try, but only if it would work. I didn't want the hassle of going into the main part of the house and finding out what cord was what as there is a cable modem connected into a switch (4 static IP's with internet) and one port of the switch hooked to a router) Anyways, didn't work he was on the router I was on the switch)
But this got me thinking. When I setup my server to do this, during one of the setup scripts it said it was setting up Internet access for client machines and that it was assigning them IP addresses threw a DHCP server that it had installed.
So, I dug up the hub connected the internet cable to hub up link and Server 1 on port 1 Server 2 on port 2 and Windows on port 3 The main server gets the internet provided IP address and routes it to the hub via a virtual interface. Server 2 is configured for DHCP and the windows box, It was set to get info automatically but it didn't fill the DNS info so I had to manually do that (just a heads up) I decided to use OpenDNS Servers (208.67.222.222 & 208.67.220.220) but im sure putting in the gateway IP address would have worked too.
So, by now if you need this I am sure you are excited and want to get to it. Like i said there are probably other ways of doing it, ways that don't involve you installing clonezilla and DRBL, maybe even just DRBL is needed, maybe one of them installed whats needed as a dependency- all I know is it works, if you know - elaborate so people know, but hey- this way not only do you have internet access on all PC's you can deploy custom images to them as well.

View 3 Replies View RelatedProgramming :: Using GPL Artwork In My Project
Nov 5, 2010I have project released under GPL. I have found an icon (.png) I want to use in it that also has a GPL license. What do I have to do, if anything, to use it legally? It's "just an icon", and while it represents a significant amount of work on someone's part, it doesn't come with any source code or embedded licenses that I can just copy and include with my project files. I'm sure I can use it because it's GPL and my project is GPL.
That's what GPL was designed for, but I don't want anyone to think I'm claiming I designed it or that I took it without giving proper credit. I just reread the GPL, and it looks like I can do anything I want with it as long as I don't restrict anyone else from doing the same and if I were to modify it, I'd have to put a notice "somewhere" (but where would that be for an icon?) acknowledging that modification. I don't see anything that would make me actually mention it at all in my documentation, etc. as long as I pass it along unmodified.
