Help needed setting up WebUI for Wireless Gateway

I have a problem setting up a webUI for my demo project.
I am just doing a simple WSN application measuring temperature on a WSN-3121 thermocouple node, and logging it on a wireless RT gateway NI 9792.
Then I wanted to create a web UI for it, and display whats in the gateway's UI - see project.
SO I'm coming up stuck with the web UI. I've tried reading as much as I can but I still dont know what I'm doing wrong.
As far as I can see, I need to create a web service in the build specs for my gateway, and place the gateway_main.vi as the vi to use. Then build it, and deploy it. Once that has happened and I run the vi on the gateway, I created a webUI as shown in the pic, where it imports the web service from the gateway using 192.168.0.16:8080 - that works fine.
When I run the webUI, it just sits there and times out.
I am using LAbview 2010. Please help.
Solved!

Hello markza,
Your approach to using Web UI Builder and understanding its use case is exactly right, the issue lies in the web service you have deployed. The VI you are building as a web service, i.e. gateway_main.vi, has while loops in it and hence cannot be used as a web service. The reason for the timeout is that your UI Builder app is calling the LV2010 web service and is getting stuck there waiting for the while loops to complete. Also, the cluster datatype is not supported in Web UI Builder so you would have to break up the Wireless Node Sampling Time input into two separate numeric inputs.
I would recommend creating a subVI out of your code inside the inner while loop in gateway_main.vi. This subVI should have two numeric inputs to replace the cluster (as mentioned above) and not have either of the Start or Stop boolean inputs. Outputs would stay the same i.e. two doubles and a boolean.
Let me know if that helps you and if you have any further questions.
Thanks!

Help needed - setting password policies for different types of accounts

Hello,
We have a situation where we have different types of users created on a solaris server. We have regular users, admins, functional accounts and device accounts. Of course solaris does not differentiate between regular user and other types, i think. The default password policy applies to all the users on the server. I want to configure different policy for different types of user accounts. Is it possible? The difference between the accounts on our side is
Regular user accounts - 8 digit numbers ( 00667265) - expire password every 90 days
Functional accounts - 8 digits starting with F ( F0253466) - do not expire, but password length must be 10-12 and complex
Device Accounts - 8 digits starting with Z ( Z2367249) - do not expire, but password length must be 12 and complex - like upper case, lower case, number, special chars etc.
Is it possible to set up different password policies, is so how?

The password expiration policy is pretty easy, it can be set on a per account basis when the account is created. I'm not aware of a simple way to define a complexity policy for groups of accounts but the policy is enforced using pam, so you should be able to write a pam module which would enforce your complexity policy. The pam manual page would be a reasonable starting point for learning about pam.

Desperate help needed to configure WVC210 for remote access?

Hi, I'm new and desperately need some help on setting up my WVC210 for remote access.
I manage to setup and see images from my WVC210 using my home LAN via both wired and also wireless.
I have 2 questions:
(a) for wireless connection, i only manage to get connection to my WVC210 if i disable the wireless security from my router. But that means i'm opening my wireless LAN to everyone. How can i still get connection to the camera if i enable the wireless security from my router. (FYI: my router is 2Wire ADSL from Singnet Mio)
(b) how can i get connection to my WVC210 from outside or in my office? I type in the camera Fixed IP address (displayed on the front screen) on the web browser, by it shows a error page. Is there some setting that i might need to adjust ?
Pls kindly help me
Thank you.

Bernard,
For Item (2) is there any difference between the camera built-in dyndns updater versus the software updater? I am under the impression that the software updater is easier to manage.
The biggest difference for you is that the camera always stays at the same location, and the laptop goes with you. Every time you access the internet from a different location with the laptop the software updater is sending the new IP address to dyndns.com. This causes you to lose access to your camera because the FQDN doesn't point to your home IP address anymore. Once the dyndns credentials are in the camera (or router) there is no management needed. The device will automatically update dyndns.com with your new IP address as it changes, and you do not need to do anything.
For Item (3), are you saying port forward 1025 is it for the 2nd camera only or for both? Or is it 2nd camera use 1025 and first camera use 8080?
Here's an example of what I mean:
Camera 1: 192.168.1.210 port 1024. In router, forward port 1024 to 192.168.1.210
Local Access: http://192.168.1.210:1024
Remote Access: http://bernards210.dyndns.org:1024 (Example)
Camera 2: 192.168.1.211 port 1025. In router, forward port 1025 to 192.168.1.211
Local Access: http://192.168.1.211:1025
Remote Access: http://bernards210.dyndns.org:1025 (Example)
Camera 3: 192.168.1.212 port 1026. In router, forward port 1026 to 192.168.1.212
Local Access: http://192.168.1.212:1026
Remote Access: http://bernards210.dyndns.org:1026 (Example)
to access the 2 camera outside, do i have to have another dyndns host name or can i use the current one for both camera?
As you can see in the above example, the dyndns name remains the same for remote access to all three cameras. The only change is the port number at the end. Your router will translate the port number to the IP address that the port is forwarded to, allowing you to select the camera that you wish to view by changing the port number in the address.
I was actually thinking that the camera web browser can show 2 camera at the same time. Is it possible?
No. Each browser window will display a single camera. You can however opens multiple instances of your browser to allow viewing of more than one camera simultaneously. A better solution is to install the Video Monitoring Software that is included with the camera which allows you to view multiple cameras in the same window.

HELP regarding making password work for wireless setup. should be easy...

Hi. i have read and tried everything. I am using a Linksys BEFW11S4 wireless access point router. Firmware version 1.44.2. i am trying to set it up so if someone wants to wirelessly use the internet (laptops, etc), they would need a password. should be simple, but its being frustrating...
i have tried to set the WEP to mandatory and set the passphrase to something and then when i try it out on my mac laptop, it doesnt work. i also tried doing line 1 of the key codes it generates and that didnt work either. this is per instructions.
i would grealy appreciate if someone could help me in this problem. i just want to be able to secure my wireless network so the only people in the apartment building that can use our internet would be me and my roommate on our laptops. thanks.

hi gizzy, what i ended up doing was making it 128 bit under wep and it gave me a code which was pretty long. then when using my mac, for wireless type on the network i chose 128 bit hex. i typed in the code that was generated for me and it ended up working to make my wireless secure. unfortunately its not some easy password i can remember, but it worked. i just had to write it down. let me know if this works for you. also, if there is anyone else out there who knows how i can make it an easy password that i can remember and have it work, please let me know.

New Feature for Wireless Gateway 3's

With the launch of our latest Wireless Gateway 3 device, we’ve introduced a new feature that guides you through personalizing your network name and password. By personalizing your network in this way, it is much easier to help family and friends connect to your network.
To make things easier, we’ve also introduced a new default behavior for our 2.4GHz and 5GHz network names. Instead of using different network names, a single network name will cover both frequencies. You get the same WiFi coverage within your home, but you don’t have to worry about connecting to both network names or knowing which of your devices can utilize the 5GHz network – your device will figure this out for you!
If you prefer to keep the networks separate, you can always login to the Wireless Gateway’s admin portal by doing the following:
Make sure you are connected to your home network over WiFi or via an ethernet cable connected to the Wireless Gateway
Open an internet browser and enter http://10.0.0.1 into the URL address bar
Login with your Wireless Gateway credentials
The default username is “admin” (without the quotation marks)
The default password is “password” (without the quotation marks)
Navigate to the “WiFi” section, found under “Gateway” > “Connection”
Choose “Edit” next to the network you wish to personalize
Change the name and password to your preference
Save your settings
Please note: If you were you connected to a WiFi network that you just changed, you will need to connect to your newly created WiFi network before accessing the internet again.

iTunes limits the number of active podcast downloads to avoid timeout problems. Since podcasts are stored on a huge variety of servers throughout the world, you can expect that at least some of those servers would choke or fill their outbound bandwidth if you tried to download all available episodes simultaneously. Limiting the active number is a tradeoff to ensure you get most of your podcast downloads.

Help needed setting up print server

i got 2 printer:
1 usb inkjet epson 1290
1 hp5100 network
i have 1 server:
serving epson for our col proof using powerripx as driver and shared via os x print server
i have 2 network interface card on the server.
my problem is: the position of the server in the office has only one network interface port, i want to have my HP connected to the 2nd network interface of the server and the server connected to the only available network point there and thus have the server serving both printer.
have set up the en1 interface, enable NAT, dhcp, firewall, but the server itself does not recognised the hp which is connected to the 2nd ethernet interface. when i move it on top of the ethernet list in system preferences it does recegnised it but the the whole print server is not accessible on the network.
can someone with more experience help me set this up.
thx

I didn't say it's impossible. I just offered an easy solution to your problem that will save you and you users some hassle in the long run (eg. when you come to troubleshoot you wn;t have to look at 2 networks and a firewall). I guess I just like easy solutions. And ,dude, 20 bucks...
If you want to go the hard(er) way you need to:
1. set up a second network address range on the second card
2. give the printer a fixed IP address within that range
3. ensure firewall is not blocking packets from/to the printer
4. config the printer on your print server & clients

Help Needed with HTML code for Image Positioning

Hi All,
Need a little help with some code for positioning images.
I initially used the following:
This is fine, but the border automatically puts a black border around the photo - how do I change it to white? Is there a way to set margins too, to prevent the text butting up against the photo?
I also used the following code with success:
<style type="text/css"
img
float:right;
border:2px solid white;
margin: 0px 0px 15px 20px
</style>
This code works, however the problem with it is it is not individual to just one photo - it moved all my photos and on that page, I wanted one photo floated to left and another to the right.
If I use this code, how can I make it photo specific, so that it only affects the placement, margins and borders of one photo?
Any help would be great.
Thanks

CSS question, not iWeb question. Regardless, use inline CSS styling for the image. You can also wrap the image in its own tag and declare an id or simply declare an id for the img tag, then set the style for the id_name:
<style type="text/css"
img#id_name
float:right;
border:2px solid white;
margin: 0px 0px 15px 20px
</style>
If you want to control the style of more than one image on a page but not all then use a class instead of an id.
the border automatically puts a black border around the photo - how do I change it to white? Is there a way to set margins too, to prevent the text butting up against the photo?
I believe you have discovered a solution for this according to your CSS code. You have set the border to white by looking at the code and adjusting it appropriately. Your margin is declared in the CSS also, adjust the pixels appropriately.
Read up some more on CSS to educate yourself further. I suggest w3schools.com or a CSS forum instead of the iWeb forum if you have CSS questions. It's kind of like if you drive your auto to the supermarket so you decide to go to the supermarket and ask everyone in the produce section to help when you have car problems. All the supermarket does is provide a place to park your auto. If you have car problems then ask a mechanic. iWeb (and most of its users) doesn't specialize in code, it simply provides an area for you to place it. Granted you might get lucky and find a mechanic in the produce section of the supermarket, but you're more likely to find a specialist at an auto swap meet (or CSS coding forum)!

Help Needed Setting Up IMAP Relay?

I an currently maintaining an OS X 10.4.11 Tiger server, running on a PowerMac G4 Mirror.
Currently, we have our mail setup through our isp via pop (they do not offer imap). All of our employees have set up several access points to the pop server (i.e. home, office, smart phone, etc.). However, the problem arises that as each device is maintaining its own mail, when accessing mail on each device, mail read on one device still shows as unread on the others. As well as, any mail sent from one device, does not exist on the others.
To eliminate the duplication, and missing mail, I thought setting up an imap server would keep all devices in sync.
My thought is, collect all the mail from the isp pop server, onto the OS X server and then have the employees access only the imap server from all the devices.
i.e.
Setup imap server
setup imap server to download mail from pop server, and save in the appropriate account.
setup all client mail accounts to access imap server.
I have been able to set up the imap server without any issues, however, I have not been able to figure out how to get the pop server mail from the isp into the local imap database.
I hope this make sense.
I know there are free services out there that will do what we want, but we do not want to rely on an external service if it is a process we can maintain internal.
If anyone can help me set this up, or suggestions on how to approach this problem, I would be very grateful.
TIA

I'd probably have a conversation with the mail ISP along the lines of "add IMAP, please" and that will either be followed by happiness, or by migrating to another mail vendor, or migrating to local mail services.
I've bucketed mail over (via imap), and it's not really a good solution; there are a number of wheels that need be kept spinning and by the time the dust settles (outages, glitches, the usual cruft), you might as well either re-host mail to to another mail ISP that offers imap (gmail, for instance), or simply run your own mail server.
Usual tools are imapsync and offlineimap, and those target (obviously) imap and not pop. (I haven't seen much that does a pop pull, but it's likely feasible.)
If you decide to host your own, you'll probably want to upgrade to something newer than the PPC gear, and you'll need to sort out your public forward and reverse DNS for your mail server, and ensure all that matches your MX record.

Help needed setting-up a Y-Cam on a WRT54GS

Has anybody set up a Y-Cam Knight surveillance camera using a WRT54GS router. I have set one up on my network. All my PC’s see it ok, the problem is I should be able it remotely access it from anywhere in the World with no PC’s on as it has a built in server, but I can’t nor can anybody else that I give my ip address (not the network address) to. I (and others) can access it using my ip address when I have the PC on and I run a third party program WebCamXP 5. It sends out a “movement detected” warning e-mail to me ok with no PC on, I have done all the setup as directed, static address, port forwarding ect .Has anybody got any ideas on the settings so I can remotely access it.

In order to Access camera remotely you need to forward ports for your camera on the router . And also make sure that the wanip address on router should be public.

NEED HELP TO SET UP SMALL NETWORK - WIRELESS SIGNAL FROM NOVATEL U760 USB

Hello -
I need help setting up a small network in my new home in Florida, which has no wired broadband capability - not cable, not dsl. My options are satellite (which I'd like to avoid) or wireless broadband via Millenicom (or now Virgin Mobile) using their Novatel U760 USB stick.
Here are the network components - someone please tell me how to set this up:
PC #1 (has wireless card, but I've connected it by ethernet to the router)
PC #2 (no wireless card; connected via ethernet to router)
MACBOOK, 1 1/2 years old (2.1 GHz Intel Core 2 Duo, 4 gigs RAM), running OS 10.58, connected wirelessly to router.
AIRPORT EXTREME BASE STATION, Model A1143.
I'm not thrilled about using a wireless 3G signal as my primary one, (sprint network, claims 600 - 1400 kbps speed), but it costs 1/2 to 1/3 of what a slightly faster satellite signal would.
I have not ordered this service yet. Before I do, I'd like a clear understanding that I can, in fact, set up my simple network, which I'd probably do the same as it's now configured with cable broadband - both PC's plug via
ethernet into the Airport Extreme router, the MacBook connects wirelessly - AND,
my question is this:
Can I plug the wireless card - a Novatel U760 USB-stick device - straight into that USB slot in the Airport Extreme base station and will it automatically recognize that device?
Or, do I have to plug it into the MacBook and somehow share that wireless signal between the 2 PC's (only 1 of which has a wireless card, so I'd have to get a card for PC #2)?
And help anyone can provide will be much appreciated!
Thanks,
Em

from the Airport FAQ #14:
"Question: Can I connect my Soundsticks or other USB speakers to AirPort Express?
Answer: No. The USB port is for connecting a printer, not for other devices."
Im assuming other devices include USB modems.
So, I would say your cheaper route would be to get a second wireless card and just share your internet connection from one of your PC.

Help setting up router for wireless printer

I recently purchased a wireless printer - but haven't been able to connect to the router. Router is a Linksys wireless G 2.4ghz w/ SecureEasySetup (SES). When I activate the SES button on the router - it will connect with the printer - but the router then re sets itself, my SSID changes to the Linksys default and I loose internet connection.
How can I use SES without the router resetting?

I assume that your wireless printer does not have SES.
When you use SES, the router resets the wireless settings. SES is designed to be used when both devices (router and wireless adapter) both have the SES feature. If only one device has the SES feature, then you cannot use the SES button, and the non-SES device must be setup manually.
Login to your router at 192.168.1.1, and write down the following settings on a piece of paper:
SSID
encryption type (probably WPA)
encryption key (sometimes called Password or Passphrase)
Next, follow the installation procedure for your wireless printer. At some point in the install procedure, it will ask you for the above info.
If you need more help, please state the model and version of your router. Also, please state the make and model of your printer.
