what i'm trying to do is create some distance between sets of child nodes in my freemind maps. See the attached png file to see what im getting at. Is there a way to do this, other than using clouds?
View 3 RepliesHave you noticed the space "background set" that is in Ubuntu from the 9.04?It is an xml file (as I discovered on this beautiful forum ).But creating it manually is very boring and long, it would be simpler to put wallpapers into a directory and use them all as background set. So I've created a simple script that generate the xml background file with the images in a directory. You can set the timetion of wallpapers and of transitions setting the proper parameters.
here's the link to the script:generateXMLBackground.shHow to use it?Create a directory and put into it all images you want to be in the background setOpen a terminal [Applications->Accessories->Terminal]Type "cd " and drag into the terminal the directory previously created and press enterDrag into the terminalhe script generateXMLBackground.sh and press enter [you can use parameters -t -d. For help use the parameter -h]The xml file has been created!!Now you only have to set it as background:in the "Change desktop background" window click "Add", navigate to the directory created at the beginning, set the type filtre to "All files" (at right bottom, normally it is 'Images') and choose the .xml file named #DIRNAME#Background.xml.Note:not run the script generateXMLBackground.sh you have not rights type into the terminal "chmod +x " drag the script and press enter (to make it executable).
I'm a starter here in linux, I have written a driver code and in that, I register my character devices by passing 0 for the major number.
To set up I used to use mknod command from terminal to create node,
Is there any method to create node dynamically from driver code during initialization and delete them at cleanup time?
Recently I have renovated an old computer which once belonged to my dad (the old HDD crashed, and I just bought a new one to replace it). My parents want me to fix this computer for my 5-year-old sister to use. I decided to use Linux Mint as the OS because everything (flash, mp3, etc.) is already configured.
How do I create a user account in Linux Mint with limited access for my sister, so that it won't mess up the entire system?
All she does is surf the web, so I'm just worried that she might accidentally mess up a system setting that I eventually will have to fix it.
Iv got an assignment to complete and I'm stuck at the basic level.
A part of the assigned problem is :
The main process will read the file, and will create N number of child processes (Where N is taken as input) as early as possible before all the children starts its execution. Before creation of each child, the main process should read the file to store all the required data in then corresponding data structure. Child processes should not read the file for getting their information.
As far as my knowledge about this , the child executes before the parent. How do I make the parent not pass the control to it's children before it finishes creating all the children?
I have a doubt about signals in C programming. I have done this little program to explain it. It creates a child process with fork and, when the child ends, receives the SIGCHLD signal and wait for its termination.Ok, quite easy, BUT when I execute this code the SIGCHLD signal is received twice, first as an error (returns -1) and the second one to finish the child process.I don't understand the meaning of the first received signal. Why is it generated? Is the code wrong? (if you add the SIGINT and press Ctrl+C during the execution it also receives two signals instead of one)
Code: #include <stdio.h>
#include <unistd.h>
#include <string.h>

I am troubleshooting something and I got this problem.
If I do "pstree -p"
It shows,
Code:
[code]....
However, it does NOT show up in "ps -elf"
Code:
ps -elf | grep soffi
0 S whho 7734 1 0 80 0 - 36435 - 11:14 pts/2 00:00:03 /usr/lib/openoffice/program/soffice.bin -splash-pipe=5
0 S whho 7833 7759 0 80 0 - 751 - 11:21 pts/3 00:00:00 grep soffi
I was wondering if 7735, 7736, 7737, 7743 were really processes. Then I checked /proc, I could cd to /proc/7735, /proc/7736, etc, but I could not ls them out. I looked at the man page of "pstree", it says,
Code:
Child threads of a process are found under the parent process and are shown with the process name in curly braces, e.g.
icecast2---13*[{icecast2}]
So, what does all this mean? Does it mean that 7735, 7736, 7737, 7743 are just threads but not processes? If so, why could I cd to /proc/<id> but not see them in "ps -elf".
I'd like to use Freemind mind mapping software on 11.3/KDE - Main Page - FreeMind - free mind mapping software
But when I try to install the RPMs, it needs some msv-xdlibs or something and then complains about un-Sun Java.
Has anybody successfully got freemind to work on 11.3/KDE - and can they give me few quick tips on how to get it operational?
Consider the following code:
Code:
int main()
{
int i=0;
pid_t pid;
for(i=0;i<2;i++)
[code]....
I get the following output:
Parent: chid_pid=4356 i=0 parent's pid=4355
This is child 4356 i=0
This is child 4357 i=1
[code]....
I can observe instead of two children(as I expect) processes there are three. This is because child process 4356 creates its own child. Why all the messages of the type "This is child X i=Y" are concentrated one under another? How exactly fork works? Is affected by the fact that I have a dual-core processor?
I want to install Ubuntu on many different new user's systems from a distance. I am looking for the simplest cleanest way to pull this off. These systems will only boot Ubuntu....no dual boot systems. Plus, I need a way to accommodate different size Hard drives such that the entire hard drive is used. There will be a novice computer user on site who can insert a cd or dvd for me and boot the machine.
View 2 Replies View RelatedCurrently one of my neighbours has his/her router transmitting open ( no encryption ) web access for anyone to enjoy. Unfortunately I do not believe he/she is aware others can use his/her internet or that the wireless feature is on at all. The reasons behind this are simple. The router is using its default SSID, and the access password and username are default. If I wanted to I could stuff up his/her router badly, but I am a nice person.
I need to locate his/her router. The only method I know of other than doorknocking is to locate it via three distance measurements from three different points. If I have 23 metres from point A for example, it could be 23 meters in any direction, creating a circle of possible positions. A second position and distance reading will allow me to narrow that down to exactly two positions, and a third distance reading with tell me exactly the spot the router is transmitting from.
I've drawn a diagram and attached it to explain what I plan to do. What I need to know how to do is get access to any information on the distance of the router from where my computer is. Even if each measurement is off by 1 or more metres, it should still be accurate enough to pinpoint a single house.
To be sure that the remote desktop was working, I tried from home, where I have both the laptop I want to connect to and the laptop from which I make the connection. It worked without any problem, but now I'm trying to connect from my work place and it's not working anymore. Both are connected to the same VPN, so I don know where the problem comes from.
View 8 Replies View RelatedI ran two scans in Zenmap: 1) Quick scan plus and 2) Quick Traceroute. Quick scan plus, under the Nmap Output tab, has a field called "Network Distance". The Quick Traceroute report under the same tab lists the HOP and RTT time. I was thinking that for a given server, the value for the Network Distance would be the same as the HOP field when initiating the scans from the same server, but they are not.

Using Linux and have an IPAQ that would like to get TomTom Navigator 5 running on. I've loaded TTN 5 exe on the IPAQ, but have not been able to get the maps loaded. The CD has the files listed as .CAB files, and I have used "cabextract" to extract those files to a directory in Linux. When I use the "file" command, I get that the extracted files are "Microsoft WinCE install header, architecture independent, 10 files, 1 registry file". Do not need TTN5 running on the PC, just want it on the IPAQ. The maps will be on an SD card as is the TTN5 exe. Still get "no maps found" error from TT5 on IPAQ with all the files extracted from one region map put onto the SD card.

I've been a Debian convert for several years now, and generally use the Iceweasel browser (currently 31.7.0) supplied in the Debian repo. I've noticed that since Google Maps added 3-D effects to its Street View interface, and changed things up a bit, that it siezes Iceweasel. You can't "drive" the streets without the screen hanging. I'm running Debian 8 AMD64, and the free Noveau drivers for a Radeon 7570 video chipset. And I duplicated the problem on another PC with an onboard Intel video chipset.
Here's what I attempting in debugging things:
1. Installed the latest Adobe flash (not sure this was necessary).
2. Tried using the non-free ATI drivers, but ran into issues and removed those.
3. Tried tinkering with about:config webgl settings -- but there's a number of those, and I didn't know the minimal number to tweak, so I reverted back to defaults.
4. And unless I'm simply missing something, the "Lite View" option for Google Maps seems to have recently disappeared.
So Google Maps Street View still wasn't working. Then I stumbled across some references to using "force=webgl" as an URL parm in Google Maps: [URL] ....
Out of curiosity then, thinking the issue is not at my end at all, I downloaded the User Agent Switcher for Iceweasel and changed my agent's response to the latest Firefox on Windows 8.1. Reloaded the Google Maps Street View, and bingo -- it works great. Google doesn't like Iceweasel because of that name in the user agent?
This is a klunky method of using Street View, and I have filed an issue with Google (but I give that about as much odds as writing one's congresscritter). Or is there some easier way to use Iceweasel with Google Maps Street View by making more about:config webgl tweaks?

When I try entering the "backslash" keys i get < and for the pipe key i get >. I have tried going through the keyboard layouts and trying other combinations but to no avail
System info
ASUS G51VX
Keyboard: Standard
Ubuntu 10.04 LTS the Lucid Lynx - released in April 2010 and supported until April 2013.
Centos 5.4 64bit fully updated. What I am doing is vsftpd is setup and nfs shares are mounted to a NAS server which is running openfiler 2.3 fully updated. openfiler is winbind to AD and pulling users and groups over.
I have it confirmed working when a ftp users connects the username/password is authenticated against AD which works. User can login and is directed to the users folder on the nfs share.
Openfiler shows me UID and GID numbers for users and groups, centos also shows me UID and GID but they are different which is causing permissions/quota's to not work right.
Both servers are setup with krb and winbind, openfiler has a more recent version of winbind.
Here is an example...
AD Users are
user UID of 160010 as an example
user1 UID 160011
When user logs into the vsftp server it works and chrooted into the directory for that user. When user uploads files I can upload but the UID in the ftp client shows 1600011 which is user1 UID
logging into windows to that share shows in the security tab that user1 uploaded the files.
Centos is mapping user as 160011
openfiler is mapping user as 160010
windows is showing the user1 in the security tab.
So it appears that centos is not mapping the right numbers to the right users and groups.
If you need details please ask for it and I will provide.
Both configs are nearly a match and I have made small changes to the config files smb.conf but it failed resolve these issues to work so I reverted back. kinit works with authentication, getent works, wbinfo -a and -u works. wbinfo -u user shows different results on both servers, but authentication works user/password and I tried a different password to test.
Is this a known bug or a silly misconfiguration? I had authentication GUI tool configure the winbind stuff so its all fairly standard on the centos machine and the openfiler gui configure winbind configs.
I've setup postfix using mysql tables and all works except for sending to an alias. The mysql logs show that postfix is only looking at the mailbox table for where to deliver the mail for the alias. However it is not looking in the virtual alias maps table. There are no complaints from postfix on startup to indicate that there is anything wrong, and if I send to a virtual domain listed as a relay on the server it does look up the virtual alias table... even though the domain is not hosted on the server....
So the question I have is where to look next? The mysql log shows the expected lookups from postfix EXCEPT for the virtual alias map queries.... why would it not be checking the table? Since it is not looking up the virtual alias it bounces the addresses back to sender complaining that the user doesn't exist... It does deliver to a virtal mailbox, however again it never checks the vitual alias table.... so it only delivers since there's a mailbox for it rather than needing an alias...

View 3 Replies View RelatedI don't start a network connection when my machine boots FC11 64 bit. When I start the connection and the Firefox browser, I always find that Firefox has set itself to work offline. I use File->work offline and uncheck that box. This fixes the problem, but only till the next reboot. Even if I exit Firefox "in an orderly manner", the next time it will have set itself to work offline.
I had this problem in previous Fedora versions. I read about two solutions on the web. One was to write a script that removed a file called extensions.cache before Firefox ran. The other was to type about:config in the address bar of Firefox, acknowledge the warning message, and use the right mouse button to togglethe value ofoolkit.networkmanager.disable from "false" to "true".Are either of these good solutions? What exactly does "network manager" do? I think of it as the gui under System->Administration->Network, but it must be more.
