Networking :: Existing Application Models For NS2 (Network Simulator)?

Jun 22, 2010

I am an undergraduate student doing some work in Cambridge, MA on NS2. As my project/paper relates to simulating different types of applications like FTP, RTP, and SIP, as they relate to commercial products (VoIP, email, bittorrent, http) and congestion, I was wondering if anyone knows of any simulation models already available besides the example ones released by NS2 and the contributed code found at [URL]. Also, does anyone know of any tcl scripts that simulate specific applications (including the transport layer and Internet layer)? I am using Ubuntu 10.04 LTS and NS2 2.34

Ubuntu Networking :: Finding Drivers For Network Adapter?

Jun 30, 2010

I've installed it and it looks great. my problem is that I cant connect to the net since I could not find the driver for my onboard network adapter. it is a Gigabyte GA 945 GCM S2L board. of coarse I searched their site but it says that Linux driver I have to achieve from 3rd party. the adapter's chipset is a Realtek RTL 8111C but I could not find the driver for it. the only one that I've found - doesn't work. I must point out that when I've searched driver for my Nvidia display adapter- I've found it on Nvidia's site and it works great.

Programming :: Perl: Determine Error Origin / Meaning In Code Call

Jan 20, 2010

I've been requested to modify a perl backup script we use which mounts a networked NAS machine. The actual mount command is called inside a system() command. In testing, I can do a test of the return value, so I'm able to tell whether or not I've mounted properly, but I can't make heads or tails out of the return on deliberate errors. (Such as mounting a non-existent box.) I'm displaying the returned value, which is 256 in my tests. The man page for mount listed error messages with values from 1 to 64, but no higher. Am I drawing this error value from the system command somehow? And what would be the best way to determine what this error means?

Fedora Networking :: Chrony Seems Very Poor At Finding A New Network Interface

Mar 21, 2011

I use chrony on my laptop thinking it would be better for it than ntp because I'm frequently connecting and disconnecting from wireless cafe access points and going in and out of suspend mode. But I've also noticed that if chrony is started before the access point is connected it never syncs to the time servers. I have to manually restart it via the service command after I connect. This doesn't seem right to me, if chrony fails to find a network at start time, doesn't it periodically try again ?

Networking :: Analyze Network Traffic For Attacks And While Finding The Attack?

Apr 9, 2010

I need to learn how to analyze network traffic for attacks and while finding the attack seems easy in my case I need to identify what hes doing. I will be happy right now if you guys can answer my question. How to identify if an attack has brought the server down? I have packet captures of an attack in progress and I noticed that every now and then the attacker would do something weird and the server would start sending packets with just the RST packet sent in response. Normally I had been seeing the RST ACK flags set or the FIN ACK bits set to terminate a connection. So once again my question is how do I tell if the traffic indicates a server crash?

Programming :: Bash Script For Finding And Replacement In Any Webpage Code?

Feb 19, 2011

I want to write Bourne-shell script that will be to do finding and replacement in any web page code (.htm file) name of the tied folder in which have been saved pictures, .css, .js and other files. This folder create a web browser when we save web page completely and has so name as web page and has ending '_files'. I have many web pages where name of their folder are incorrect. Of course, my web browser shows these web pages without pictures. I can count amount of web pages in a folder (/path) needed for me.

1) find /path -type f -name "*.htm*" -print | grep -c .htm or find /path -type f -name *.htm | wc -l I can get list of web pages.

2) ls /path *.htm > out-list But I don't know how to assign the value from out-list (2) or result commands from pipeline (1) to a variable. Then I want to do next:


# where variable 'list' is an amount of web pages
while [ $var -le $list ]


4)assign the 1st (then 2nd , etc. ) value from out-list (2) to variable 'webfile'
sed -n $var,+0p out-spisok

5)find the 1st string value '_files' in the 'webfile' grep -m1 _files $webfile

6)For example, 'abracadabra_files' is an incorrect folder in the 'webfile' I must to know start and end position 'abracadabra' without ending '_files', "cut" name of the incorrect folder and assign it to the variable 'finder' finder = 'abracadabra' BTW, name of a folder before '_files' is between '="' and '_files' in any web page code.

7)foldernew = $webfile (without '.htm')' foldernew' is equal with name of the tied folder without ending '_files' in the folder '/path'

8)find and replace in the 'webfile' and save result in the 'webfile-out'sed s/$finder/$foldernew/g $webfile > $webfile-out

Programming :: Finding A Partition Type Reader Script / Code?

Aug 6, 2010

I was wondering if there is anyone who has some kind of a small script/code (preferably in C/C++) which reads a partition and just displays the type. For example, the script/code would be called partype and should be something like this: partype /dev/sda1, will read sda1 and display for example ext4, because sda1 was formated as ext4.

Note: I'm not a developer so I have no idea how this should be done, plus I would like the script/code to do it by itself the checking, without using fdisk/sfdisk/cfdisk/parted/gparted, because none of this apps work quite well when it comes to the partition type or file system type.
