Had a go at using an old 2611 at home, connecting it to the cable modem.

The router gets it's IP ok via DHCP

Here's the config (just basics at the moment)

!
version 12.3
service config
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption ...

I think all the routers in PT work.

Send your config to BThomson1984@aol.com and I'll do it, you can the do a "show run" to see what I did.

But I'd defo have a look at some vids.

You need a router to configure inter vlan routing. Check out some youtubes, there's some great stuff on the subject

Bazza84

You could use the server as a domain controler, this would allow you to create logons for many users. All the accounts are stored on the server, and can be administered very easily.

Set up Active directory on the server
Put all the machines on the domain
Create ser accounts for everyone

There's ...

Not sure if this is what you want, but propagation time is simply a Distance/Speed calculation

roughly

100*10^3 / 3*10^8 = 0.000333s

Transmission time is

Data / Connection Speed in bits per second

From this, the normalised delay bandwidth can be found with
Propagation time / Transmission time

One more for you

I know how to convert signal to noise ratio's into dB, but how do you convert dB into SNR?

Bazza84

Thankyou gents

How long would it take to send 1.68 GB of data over a 2 Mbps link?

What is the formula used here?

Thanks

Bazza84

Thank you very much

How can I make it into a scipt?

Bazza84

Realy stuck, I'm a total scripting nooby

I need a bash-shell script that terminates all processes of a certain name which is given to the shell script as argument.

Any help would be so greatly appreciated

Thanks again

Can't for the life of me find the number of symbols Direct Sequence Spread Spectrum uses, anyone have any knolodge on this type of encodong?

Sorry if this is the wrong forum, although it is networking.

Thanks

Bazza84

Strange... Have you put enough serial interfaces on the actuall device? And then gone through each interface and assigned a DLCI and a name?

I'm using 5.2, but it seems to work fine.

Make sure you're not trying to use the same local DLCI more than once.

Bazza84

This is my set-up

S1: has these DLCI's:
101
102
103

S2: has these
101
102
103

S3: has these
101
102
103

So

S1 (101) to S2 (101)
S1 (102) to S3 (101)
S2 (102) to S3 (102)

DCLI's are only localy significant, but you need one for each Serial interface it's mapped to.

Bazza84

Thanks again

Aw it's University nonsense, have a hard time with one of the modules hate world!!

Bazza84

Does anyone know how many symbols a high end cable modem send, and what the symbol rate is?

Realy stuck here, any help would be muchly appreciated as always

Thanks

Bazza84

Thankyou

Anyone know how to get Mbps from 15 MHz?

Thanks

What would be the best error correction protocol for a 2km Coaxial cable WAN link?

The data crossing the cable is large file transfers and voice traffic.

Looking for the most efficient method.

Thanks again

Bazza84

First thing you need is to configure the addresses on the serial interfaces, or whatever interface is connecting the routers together.

To get them all talking, you can do one of these options

Create static routes for each interface (It's a pain in the ass)

Configure a routing protocol on each ...

Bazza84

What kind of router are you using? Most decent routers have multiple interfaces, all of which can be configured with seperate networks/subnets.

http://www.freeimagehosting.net/uploads/th.a286cddb12.png

The above is a simple topology that will work, for the networks to be able to talk to each ...

For Cisco networking you could try GNS3

http://www.gns3.net/

Or Cisco Packet tracer, whic is only available for Cisco networking academy student, but I'm sure if you keep an ear to the ground you will find it

Bazza84

Sounds like my 2nd year project, and that was 20,000 words and 200 odd pages of screen shots too, nine days...you might be cutting it a little short dude.

Bazza84

You'll need to supply more information

What's your public (Internet) IP, and is it a static address?
What interface is it on?
You'll probably be using NAT/PAT, so what pivate addresses do you want for you LAN?
What interface do you have (Ethernet/Fast Ethernet)?

Bazza84

This helped me

Bazza84

Yeah I'm just looking to extend it for now

Thanks

Bazza84

I've heard about making the second switch a VTP client? What about the 1st switch?

Then is it just a case making another trunk between the two switches?

Thanks kindly

Bazza84

Must be asking too much

Bazza84

How do I allow this network to access other networks such as the internet, other branches etc

Do I need another router, or can make use of the "router on a stick"?

What about the default gateways on the machines?

Thanks again

Bazza84

Why not take ripv2 off?

routerr rip
no net xxx.xxx.xxx.xxx

Bazza84

What about setting up a proxy server, is this needed to allow multiple subnets to access the internet?

Bazza84

Thanks

Is there anything else needed to get both subnets accessing the internet? Is it just a case of adding static routes?

Thanks again

Bazza84

Can this be done, just by using Windows 2003? If not, how else can I do it?

Bazza84

The two "routers" are actually just Windows Server 2003 running RRAS, they are meant to be in different departments (it's just a Uni project) But I do have to machines in my house set-up this way, all is working as it should.

1st network 172.20.24.0
2nd network 172.30.24.0

Both routers are running ...

Bazza84

Hi, I've set up a small home lab to practise for Uni.

http://www.freeimagehosting.net/uploads/th.4192a91102.png

Everything works fine, but now I would like to give the whole network internet access.

Do I need a third router for NAT or can I use any one of the current two?

Is there anything ...

Bazza84

Can I use this as a Router for my new cable broadband? If so, is there any steps I'll need to take to do this?

Thanks

Bazza84

Yeah Im looking for this on all machines on the domain

Could you help out a nooby with that batch file.

Stonecat, thanks again! Thats a cracker too!

Bazza84

It's a Windows 2003 domain

That is the very one!

Thanks Sir

Hi

I'm looking for a script that displays computer name, IP address and other such info.

I was told there were loads of such scripts available for free online, is this true, if so could you point me in the right direction

Thanks again

Bazza84

Thanks TonyT

Very much appreciated! :-)
