I am working with NS-2, I am facing a situation where I need to re align the transmission range of a particular node. Can I do this by modifying the protocol's source code? I should not change the default value from 250, only few nodes who satisfy a particular criterion should be reset to some other range like 200 or 300. How can I do this?

View 8 Replies View Relatedthere are 3 nodes..A,B and C. Node A wants to send information to Node B but it does so by sending it to Node C first which then sends to B. And similarly Node B sends to A. In this simultaneously C doesn't send to both A and B. This is the in built algorithm..but i want to change it to: A and B send their packets to C and C sends both these packets to A and B..by ORing... In the receiver side...node A can receive the wanted packet and also B. Where do i change the algorithm?

After each bootup, I need to run the following on the master machine:

Do we need to specify which machine should be the primary node every time? Is there any method to make the machine "know" it's itself the primary node?
I have created a simple menu driven script for our Operations to take care of the basic monitoring and managing of our production application from the back-end. Now, the script when tested in UAT environment was fine, but when deployed to production it kind of behaved oddly.hen the Operator chooses an option from the menu he is given the output and at the end is prompted to return to the main menu by using ctrl+c. In production, this return does not occur for some strange reason and the program just sits there.The session becomes unresponsive after that and I'm forced to terminated it by closing the PuTTY.I tried enabling the debug mode too (set -x) and still was not able to find any useful hints/trails as to why.
View 5 Replies View RelatedI am familiar with windows 2008 cluster servers, and I just started testing with centos cluster. I am creating a simple 2-node cluster, for a simple ping test.
Node 1: 10.0.0.1

Virtual ip: 10.0.0.10
So far, I can ping a virtual ip, and manually relocate it between the nodes, but I didn't figure out, how to do this automatically. So this is my question: How can I setup the cluster, to it automatically failover the a service to another node case one node fails?
I don't have much experience in clustering. And I'm deploying a cluster system on CentOS.But I don't know how long a node failover and another node take over those resouces to continue running service is good, fast or slow? 1s, 10s or

Whenever I use lpr on the command-line to print a text file, it uses DejaVu Sans Mono as the font. Is there a way to change this? I'd like to use Terminus as the font instead. I found that CUPS uses Courier as the default font for text files, so somewhere Courier is being aliased to DejaVu Sans Mono, and I have no idea where.

How do I change my default keyring password in F11?
The instructions from here no longer work:
Code:
$ yum search gnome-keyring-manager
Loaded plugins: dellsysidplugin2, fastestmirror, refresh-packagekit
Warning: No matches found for: gnome-keyring-manager
No Matches found
Longer story:
Somehow I got my keyring and login passwords out of sync. I went to change my login password using passwd on the terminal. I meant to change it to (let's say) "abcdef" but typed "abcdfe" twice. Realizing my mistake I tried to used passwd a second time to change it to "abcdef", but passwd complained that the new password was too similar to the old. So I used "su -c 'passwd myusername'" - I was able to change my login password but I guess this did not update my keyring password. I've tried changing my password using passwd as myself (not root) to something completelydifferent, but my keyring password remains the first password (e.g. "abcdfe").

I'm trying to change the desktop to KDE so that it's persistent across boots. I did the usual thing of adding /etc/sysconfig/desktop and adding the appropriate parameters, but for whatever reason, whenever I reboot, it still loads Gnome. Now here's where it gets annoying: I can switch to runlevel 3, type startx, and then it will read /etc/sysconfig/desktop and load KDE properly. I've been banging my head against a wall over this one. Where is the call made to start gdm? I think I'll probably wind up changing the default runlevel to 3, but I'm still curious as to why those scripts are not executed on boot.
View 1 Replies View RelatedI've been trying to research this, but I don't really understand IP routing and it's bugging me that I can't fix this problem. I have a dedicated server (fedora core 7) with 3 IP addresses on the same eth0 interface. On the default IP address 62.193.226.127, there is some routing problem because I can't connect from the server to some other sites. Using one of the other IP addresses, like 62.193.252.129, I can connect fine. Additionally this address is better for sending mail because it coincides with the main domain name from which the mail is sent.My question is: how can I configure networking so that outgoing traffic from the box goes via 62.193.252.129?

I started a torrent earlier today and tried to use the default program "transmission". Never liked it all that much but, first thing it did was to present me with a list of the files in the torrent I was trying to dl. About 40 files and I only wanted to grab one of the files. For some reason, I have to unclick 39 files so that I can leave one clicked. There doesn't seem to be a "un-select-all" tool perhaps there is a hidden selector? Or do the developers of the program think that I really do need to download all the files?

Unfortunately, I have a minor issue that I haven't yet figured out how to fix: I can't change the default applications or the file type associations.

But after I end my session and log back it, Firefox is back to being the default browser.
I have the same issues when trying to change what applications open filetypes. .rtf files have been opening in Wordpad in Wine. When I try to change it to Writer through the "Open with" dialog, it retains the change for that session but resets after I log out.

I can't switch of the mainboard ethernet option (eth0) in the bios and have tried to change the settings in the ifconfig-eth0 and -eth1 files by changing the hardware addresses as elsewhere recommended, but that doesn't work. During start-up it then gives me an error message that the MAC number was not the expected one. This would indicate that the network options are kept/read elsewhere.
