Networking :: Gateway Assignment And Use Of DHCP Relay Agents + DHRELAY

Jun 22, 2010

I am having some difficulties comprehending some networking concepts relating to multiple subnets and dhcp servers, or dhcp relay servers. I have built home networks many times before, and they have all followed a very simple formula. A single subnet, let's say 192.168.1.0 which is fairly typical for me. My network's DNS server is always also my networks DHCP server. Typically at 192.168.1.1. When a DHCP client broadcasts for an IP over the subnet, 192.168.1.1(My DNS/DHCP server) will not only tell the client what it's new IP is to be, but will also tell the client what it's Gateway server is. This is ALSO 192.168.1.1 for me typically.

In this manner, a client broadcasts for networking information and is given a usable IP, and told to use 192.168.1.1 for most other functionality. Very simple. However, I am uncertain how to expand this to other subnets. Say.. 192.168.2.0.

A: I can use a separate DHCP server for each subnet. or B: I can use a DHCP Relay agent for 192.168.2.0 to pass the DHCP requests to the primary DHCP server on the 192.168.1.0 subnet.

Option A: is fairly straight forward and have had it functioning fine, but it is really B: I want to know more about. It seems somehow much cleaner to me. I prefer to centralize as much of my network provisioning services as possible. It makes it easier to manage TYPICALLY. My question though is related to Gateways and the use of DHCP Relay Agents....

Networking :: Simulate A 500Mbps Link On A 1000Mbps?

Mar 31, 2010

I need to simulate a 500Mbps link with a 100ms delay and a loss probability of 0.0001% on an ethernet link between two gigabit ethernet cards...I tryed to use these commands:

# tc qdisc add dev lo root handle 1:0 netem delay 100ms loss 0.0001
# tc qdisc add dev lo parent 1:1 handle 10: tbf rate 500Mbit buffer XXXX limit YYYYY

But during some simulation throughputs are very low ( 190Kbps....210Kbps....) for different values of XXXX and YYYY.... (I don't want that the loss probability is caused by the buffer and the limit value but only by the loss probability setted on netem...)

Networking :: Simulate A Script For Two UES Connected With A High Speed Common Channel?

Apr 14, 2011

I'm trying to simulate a script for two UES connected with a high speed common channel. The file is the same I've used in not enhanced umts with some changes, and it worked perfectly. The changes are indicated in the EURANE guide.

There are two lines of code:

Code:
$bs setErrorTrace 0 "UE1_trace_file"
$bs setErrorTrace 1 "UE2_trace_file"
that give me an error when I try to run the file .tcl
I've downloaded files I needed from EURANE page: SNRBLERMatrix and Ray_corr-3kmh-300m-0-200s-UEnr1,Ray_corr-3kmh-500m-0-200s-UEnr1,Ray_corr-3kmh-700m-0-200s-UEnr1
I've tried to use the first and the third for UE1 and UE2 respectively

[Code]...

I edit: The definition of the connection of TCP agents and sinks was incorrect.

Kontact worked, but I had to manually start Akonadi (from system tray) to get contacts to work.After reboot, Kontact won't start, instead showing a red box with an X, and "Akondaki not operational".The box on the screen (selftest) says "MySQL server log contains errors", and "Akonadi server process not registered at D-Bus".The report is saves says Test 14: error "no resource agents found".If I close the Akonadi window, and try to start Akonadi from the system tray, it gives the same errors.

How could I use pty's to simulate a serial device?

Actually I would like to temporary replace the /dev/ttyS1 file by one end of the pty. How could I do this? Is there a command to create a pty pair?

Ubuntu Networking :: SSH To A Mobile Laptop?

Sep 13, 2010

I have two dual-booted Windows/Ubuntu machines--one desktop and one laptop--and both have SSH servers installed. At home, I use port-forwarding to connect to these servers externally.

I am interested however, in being able to connect to my laptop's ssh server no matter where it is. I am interested in this partly due to anti-theft precautions and partly just curiosity. I know there is anti theft software that lets you remotely modify your computer--from ANY IP address--and I want to know if you can do this with SSH. Imagine someone stole my laptop and connected to the internet in a random location. Assuming i somehow know this ip address, is there any way I could SSH to it? (I doubt the router would forward port 22 or whatever to this computer...)

Debian Multimedia :: How To Simulate The Enter Key In X Windows

Dec 16, 2014

When I drink tea, the water splashed on my keyboard. It didn't cause any problems until a few mins ago. Now my Enter and right hand side shift key don't function any more (The new line in this text is copied from other thread).

So I would like to know how can I simulate an enter key press so that e.g. a command can be executed in terminal. Because I have some source code uncommitted, I want them at least get committed first.

General :: Simulate Ack By Using Grep With The Right Combination Of Options?

Aug 25, 2011

I have ack-grep installed on my local machine, and find it indispensable for quickly 'acking' through a codebase when debugging. However, on my cheap shared hosting, there is no ack-grep. One of the testimonials on betterthangrep.com mentions a

Rube Goldberg mess of find/grep/xargs which sounds like what I need, but coming from the opposite direction.

Ubuntu :: Simulate Keypress Via Keyboard Shortcut?

Feb 21, 2011

I have a G15v1. After going through hoops and loops to get it working only to discover that you only needed to install g15daemon through the Ubuntu Software Center, I found myself with one big problem. I migrated from windows just now, and there, I had my macro keys(the extra ones) bound to CTRL+W, CTRL+T and to a simulated mouse-wheel scroll so I could navigate the web more easily. How would I go about doing that? I figured, if I used the System->Preferences->Keyboard Shortcuts thingy and bound my key, in my case XF86Launch5, to a command similar to "simulate keypress CTRL+W"(I know it's totally wrong, just to give you an idea), I might be able to get it working again. Only problem is, I can't find anything like that. Any of you has any clue about it? I googled but I only find C++/Java/coding related results, which are not exactly what I need to do.
