Confused as to how to connect network.

Hi,
Having successfully set up my server for the first time, (thanks to a lot of you!) my thoughts now are turning to a permanent installation here at our small school. Next to my server I have two network points. One for direct Internet - the other LAN (which connects to a switch or Hub). My current successful attempt involved connecting a Base Station Extreme to the Internet point, and then connecting the server via ethernet and Macbooks wirelessly to this. Great - it worked. But now I want to incorporate the wired computers. This is where is gets really confusing for me. I have thought of two possible solutions (but please tell me I am daft!, and tell me how it should be done - easily - in layman terms please!!).
Firstly I though I would connect Ethernet Port 1 to the internet, and then Share DHCP on Ethernet Port 2. But - this seems to be problematic to a new server user according to posts I have seen - or is it?
My second idea - and I have no idea if this will work - was to connect the internet, LAN and server to a small switch or hub by the server. Would this solve my problem? Could I then use only Ethernet Port 1? Will everyone on the LAN see the server and be able to connect to the internet - or will this just not work?

I'm with Roger. Putting a fileserver on the perimeter of a network is not the best bet. It can be done, but will require a bit of extra work, and is not the most secure option. If you get a firewall appliance, you can hook that to your internet connection and to your main switch. This will allow for some added security and well as allow you to to link aggregation on your two XServe ethernet ports for better file server speeds.. You can close all ports on the WAN side except for what is needed for internet access. Your file server will need several ports open for your LAN, while these same ports will be closed to WAN traffic. You'll also have a DMZ available for web, and mail services.
On the other hand if you already know all this, and are really adept with DNS and configuring ipfw, then nevermind...

How to connect network with java?

If I have already configured the network connection, my java application can work through it. But if I don't configure the network connection, how can my java application connect the nwtwork automatically? For example, popup a dialup dialog.
Please tell me how to solve it if you know, thanks a million.

I believe you will have to resort to native (C) code and JNI...

How to use an external start button for 6024E w/ sc-2345, I would like it to function like a start button in LabView but I don't know how to connect the external button to the sc-2345's connector block

I am confused as to how to connect my external start botton. I would like it to function like a start button on a front panel of a VI. I would like to use the +5V on pin 14 but I really don't know where to go from here. Any guidence for a novice would be most appreciated.

phod,
This is the LabVIEW Real-Time forum, so I suggest that in the future that you post this type of question to the Multifunction DAQ forum.
For the simplest solution you will have to connect your button to a digital line of your board, consult the sc-2345 user manual for a diagram of where these lines are exposed. You will have to connect your start button in series with a line that is high, such as your 5V pin or another digital line. Then connect this to a digital line that will be your start trigger.
Your program can poll the digital line that is connected to your button in a while loop and when it goes high, it lets the rest of the program execute. For the programming, I suggest you take a look at the shipping examples that come with LabVIEW. If yo
u have LabVIEW 7.0 go to Help>>Find Examples. Open Hardware Input Output>>Traditional DAQ>>Digital Input and Output>>E Series for some examples of digital I/O programming with E-series boards.
Hope that gets you started.

How to connect my macbook pro to a computer-to-computer network?

how to connect my macbook pro to a computer-to-computer network? My home computer is a Window 8 OS. Thx.

The easiest way, and it may work from scratch, is to share the folders/drives you want access to on your pc, noticing what are the default parameters (eg "workgroup" etc.).
Then, you can connect your mac directly by ethernet, for instance, and, in Finder, go to > Network, you should see the folders/drives. You may be asked to provide user/password.
Don't get confused by regular/crossed ethernet cable, as mac can cross by software, so a regular cable will be ok.
Anyway, either you isd modem has the ability to connect several devices (multiple ethernet sockets, or wifi), or you can buy a router, which isn't expansive.

How to Connect Airport Express to Existing Wireless Network (Client Mode)

I am posting this for everyone tearing their hair out trying to connect the Airport Express to your own existing home wireless network. After spending 2 hours last night installing this on my father-in-law's home network, I hope to be able to save someone else the agony we went through.
So here's the situation:
Say you already have your own home network set up, and all you want is to be able to use AirTunes to play music off iTunes into your speaker system. And, you don't need the printer sharing capability nor creation of another wireless network (2 of the features of Airport Express). Then this solution is for you - read on.
Unfortunately, Apple's user manual is very unclear how to connect Airport Express to your own network. When you look at the picture diagram they provide, they show Airport Express picking up its signal from another Apple-oriented base. This can make you think you need to buy another piece of hardware to make it work. DON'T If you read through the manual, the Support section here, etc., you will hear lots of talk about "Client Mode" - and that this is the only way to get it to work. Nice - but no one really tells you how to set up the Airport in client mode.
Do yourself a favor, toss that user manual aside and run these steps.
(Note: These directions assume your DSL/Cable Modem is hooked up to a wireless router or acts as its own wireless router)
1. Get a cat5 Ethernet cable (anything but an orange cable - that's a crossover cable) like you would use to connect your PC to your router to pick up the Internet.
2. Connect the Ethernet cable to the router on one end, and to the Airport Express unit on the other end.
3. Plug in your Airport Express unit to the wall (this will not necessarily become its permanent location - you will be able to move it later). The light will glow solid Amber for about 30-45 seconds while it starts up, then blink Amber. At this point, the unit is ready to operate.
4. Install the CD to the PC where your iTunes music is stored. This should be painless. Once you open the program, it should detect the Airport unit.
5. At this point, the on-screen wizard will present you with your options, and walk you through the setup. This is much like the user manual describes - and you should be good to go form here forward.
Some pointers:
- When asked if you want to create a new network, join an existing network, or connect via Ethernet, choose the middle option for joining an existing network. You will need to know the name of your network, the password to connect to the network (if present), and the type of encryption used on the network (e.g. WEP, WPA, etc.). Side note, WPA is recommended, as it is a higher level of security than WEP. You will be able to configure the Airport Express unit to automatically login to your network.
- I would recommend, when creating a password for the Airport Express unit, use the same password as your network, to avoid confusion.
6. The very last step will ask you to save the settings to the Airport Express. Here's the kicker - when you save the settings, you are TRICKING the Airport Express into no longer acting as a network broadcaster, but instead being a "slave" to your own network. What do I mean? You will lose the connection from your PC to the Airport Express - an error message will pop up telling you the unit can no longer be found. While you might think you did something wrong, you actually were successful!
7. Unplug your Airport Express, and disconnect the Ethernet cable from your router and the Airport unit. This will no longer be needed.
8. Go to your desired location where you want to plug in your Airport Express unit. Before plugging it in, connect your Audio cable from the Airport Express to your audio receiver. Once that is connected, then plug in the Airport Express unit. The light will glow solid Amber for 30-45 seconds while it loads, and then will blink Amber for a brief period of time before turning solid GREEN. When this happens, you have successfully connected the Airport Express to your home network!
9. Go back to your PC with iTunes. Open the Airport software - you should now have a listing for your Airport Express unit in the upper left. Click on this, and the wizard will guide you through connecting - you will need the password you created for the unit. You only need to go through this wizard once, and when finished, the software will tell you that can now use iTunes with your Airport unit.
10. Open iTunes. On the lower right, you will see a dropdown for Speakers, and it should be defaulted to My Computer. Click on that drop-down, and you will see the name of your Airport unit. Click on that name, and now your music will broadcast to the Airport unit!
11. Play a song in iTunes. Go to your audio receiver, and connect it to the channel for your external connection to the Airport Express unit. You should hear your music from iTunes. CONGRATULATIONS! =)
I hope these instructions were helpful - I am happy to answer any questions, so feel free to contact me, *******************@*****.**.

Thanks for the detailed directions. You are absolutely correct in stating that people should toss the user manual; it's pretty worthless. I have had a problem setting up my new Airport Express as I have described in an earlier post - http://discussions.apple.com/thread.jspa?threadID=1839873&tstart=45
One quick question - does using your setup process set the AE up as part of a distributed network where the AE is acting as a wireless router where it is extending the range of your network? Or, is it simply a wireless connection to your stereo for iTunes? I am interested in having both, since my AE will be at the other end of the house from the main wireless router.
Thanks

How to connect a Sony Bravia TV to the internet through your Airport network

Since it took me a lot of time to figure out how to connect my Sony Bravia TV to the internet through my Airport network, I better share how to do it. Hopefully saving others a lot of time.
My 32EX600 Sony Bravia TV is Ethernet connected to my Mac Mini, which is part of my Airport network, together with another Mac, an Airport Extreme Base Station and an ADSL modem/router. Moreover, the Mac Mini is connected to the TV by HDMI.
Whatever I tried in the TV’s Wired Network Set-up (Auto, or Manual with manual IP, Subnet Mask, Default Gateway and DNS IPs), I couldn’t get it right. Cable Connection and Local Access were mostly OK, Internet Access always Failed.
The solution lies in the Sharing panel of the System Preferences of the Mac Mini. In the Internet Sharing item of that panel, you should choose to “share your internet connection from WiFi to computers (the TV in this case) using Ethernet“, and NOT (as I had chosen before and seemed so obvious) “share your internet connection from Airport to computers using Ethernet“. After that change, the Bravia Network Set-up, using the Wired and Auto options, flawlessly connected to the internet. No expensive (Sony) WiFi USB dongle needed.

I have now had a detailed reply from Sony Europe and the way to do this is to:
1.       Press Home on the TV Setup
2.       Use the right and left arrow to select Setting.
3.       Use the up and down to select Network, press Enter.
4.       Select Network Setup.
5.       Select Wireless setup.
6.       Select Scan
7.       Select your network
8.       A new screen will appear asking for entering the security key.
9.       Enter your WPA2 key.
10.   Select Enter.
11.   It will take you back to the same screen asking for entering the
security key.
12.   Press the right arrow.
13.   Select Auto.
14.   Press the right arrow.
15.   Select Save and connect.
These instructions are not the same as shown on the TV but they worked fine for me so they may help others with a similar problem.

How to connect old aiport express to my new Airport Extreme? My Ipad says "base station e5713b cannot be configured" and my AirPort tool on my PC will not permit me to add my new Airport Extreme network (no network names to choose from)

How to connect old aiport express to my new Airport Extreme?
I have a PC running with Win7 and just replaced my Jensen With a brand New Airport Extreme.
I have set up the Airport Extreme to the internet, Iphones and Ipads and it work as it should.
I have downloaded latest Version of Airport tool on my PC. In addition i have downloaded the airport tool for Ipad.
I have reset one of my airport Express and it now shows up both on the Ipad and on the PC airport tool.
My Ipad says "base station e5713b cannot be configured."
I have wired the airport Express to my Ethernet to be able to "see it" on my Airport tool.
My AirPort tool on the PC will not permit me to add the airport Express to my new Airport Extreme network (no network names on the drop-down list to choose from). I wished for an easy set-up, but nothing seems to be plug and play as the Commercial says.. can you please help me?
Sigve

Hi
Thanks for Swift reply.
Yep - I in fact have two A1088 and one A1264
I actually bought the new router because the Jensen
router always lost connection to the Airport Express after some hours or days. I
always needed to restart my Jensen to play music and that was driving my wife
mad. The hope was that the Extreme should fix this. Both A1088 have been set up
to only stream music to two of my stereo amplifiers from my PC’s Itunes library.
Are the A1088 now useless?
The A1264 has been set up to feed internet into a Denon Reciever that needed Ethernet cable.
Please advise
Regards
Sigve

How to connect my mac book pro to network printer Canon IR 2010f?

I'm desperate to know how to connect my Mac book Pro to network printer Canon IR 2010f. This printer has an independent system, therefore, no need a PC to be on, in order to print. But this printer is a network printer. Help me please.

The Canon UFR2 v2.20 driver for Mac OS X does not list the iR2010F as a supported model. The same is so for the Canon PS driver so I therefore believe this model is PCL5e only.
What you should do is open Safari and type the IP address of the iR2010F. This will connect to the internal web page of the copier and from the provided pages you should be able to see what printer languages are supported.
If it only lists PCL then you will be able to print to this copier using the Generic PCL driver included with 10.6.
So if you open Print & Fax, click + to add and then select IP > LPD for the protocol you can then enter the IP address of the iR2010F and leave the queue name blank. For the name you can change that to iR1020F and for the Print Using, select Generic PCL Laser Printer.
One note with regards to this driver. It is defaulted to 300dpi so you will need to open the print dialog when you do print and change the resolution to 600dpi to get better print quality.

How to connect a "Clear Network" Modem to my Airport Xtreme?

Hello friends. I recently purchased the clear network modem. I need to know how to connect it to my Airport Extreme and get my local network at home working with 4 computers. Thank you!

Except that I don't know much about the Extreme, it should be simple.
Power down the computers, the Extreme, & the Clear Modem, wait 5 minutes, connect an Ethernet cable, (it is one with Ethernet right?), from the Clear Modem to the WAN port of the Extreme, power up the Modem, wait 3 minutes & power up the Extreme, wait 2 minutes & power up the Mac(s).
Windows directions, but basically the same to setup the Extreme to hand out IPs...
