Datasocket 4.0 Network Client stops if Data are with Attirutes

OS: W2000pro, VB50pro, DSServer40(370)
Dear friends,
I have some misterious problem with DS40.
Configuration : I have one writer with DSServer 40 on one computer and several clients on the same and other computers.
Problem:
The Clients Data on remote computers is stopped after some number of writes (???). The last value remains the same and status is : "Active connected" .
Along the normal value I use some Attributes:
CWDataSocket1.Data.Value = Value
Call CWDataSocket1.Data.SetAttribute("Quality", 192)
Call CWDataSocket1.Data.SetAttribute("TimeStamp", Now)
CWDataSocket1.Update
This doesn't happen if The writer and Client reside on the same computor !
If I do this wit
hout attributes then everything is OK.
I think the problem is With Writer ?
The same happens in Labwindows CVI 5.01.
To test: I use OneWriter.exe and OneClient.exe on one computer. The Datasocket server is on other computer.
Thank you in advance,
Vojko

Have you noticed if there is any abnormal behavior in the connection between the two computers once the dataflow stops? Can you still ping the computer running the server? Does dataflow pick-up normally again if you just restart the client? It might be helpful to create an event handler for the status updated event in order to log the connection behavior so that you can tell us whether or not the status ever updates to anything other than connected while it is running.
If you try the following scenario:
Run the server on one computer, the writer and client on another, and a copy of the client on a third.
does the client on the second computer stop reading data when the client on the third does?
We have a couple of examples that show the use of attributes with Da
taSocket in CVI, and I would like for you to try them out with the scenarios that you presented to see if they exhibit the same behavior. You can locate them at the following two links:

"The data area passed to a system call is too small" NFS client Windows 2008 R2 SP1

Hi
I need to map a Hyper-V virtual windows server to a UNIX folder, but when i made de mapping and tried to navigate in to the mapped unit and shows me:
"The data area passed to a system call is too small"
I tried too many things like adding a registry key (and windows 2008 r2 already has)
Use a similar account between Unix and Windows domain
I done the steps in the document:
http://technet.microsoft.com/en-us/library/cc753302(WS.10).aspx
And nothing, this is just frustrating, also I disabled the firewall in the virtual machine and the host server.
I have a Windows 2008 Domain R2 functionality and the virtual machine is Windows 2008 R2 too.
The version of unix are:
AIX6.1 x64
AIX 6.3 x64
AIX 5.1 x86
Any Idea?
Thanks!

Hi,
You may perform the following troubleshooting suggestions:
l
Change how your NFS servers export the NFS shares and make them allow connections from high ports.
l
Add UseReservedPorts DWORD value under HKLM\Software\Microsoft\Client for NFS\CurrentVersion\Default and set it to 1. Restart the Client for NFS service to allow
the change to take effect.
For more information, please refer to the following Microsoft MSDN blog:
"Network Error 53", "The data area passed to a system call is too small" or "Unknown Error"

Dates issue with BAPI_NETWORK_MAINTAIN

Dear Frens,
I have issue with dates in the activities and in the header of network while using BAPI_NETWORK_MAINTAIN. I am creating a new network with the deleted activities of an already
existing network. The network is being created with the activity early_start_Date and finsh dates as
sy-datum and the network header has early start dates set to sy-datum.
While passing values to the table parameter I_ACTIVITY of the BAPI , the dates are as available in the
existing network. But for unknown reason, The newly created network dates are with the today's date.
Can any one please let me know the possible reason for this.
Also every time I create a new network with multiple activities the new network is being created without first activity of the set of activities to be created.
Here also the table parameter I_ACTIVITY has all the activities that are to be created for new network.
I appreciate your quick response on this.
Regards
Priya

Hi Lakshmi,
I was able to solve the problem but not by the answer you gave. I had to write a WAIT up to 3 seconds after commit and that updated the table.Thanks anyways

Memory management - Data area

Hi,
I need to define a data area with 65 channels and a channel length of 10000000. With different configurations DIAdem shows up the following error messages:
1-The defined area is too large for this computer to reboot
2-Numeric value out of valid range (6400000000>2147483647)!
Error occurred while installing the data matrix
Does anyone know how to solve it? Minimum necessary memory RAM? Free space necessary on HD? I tried with DIAdem 8.1 & 9.1 with same result.
Help will be appreciated,
Thanks.

Thanks for your quick answer,
Actually I solved the problem splitting the Data files to reduce the length and after the analysis I join the results channels. I did it in this way because I didn’t want to expend much time modifying the code that I already had to analyse the data. My code performs several filters to the data and then searches all the positive peaks over zero and the negative peaks under zero in order to plot some histograms related to the peaks.
I think that your solutions are well suitable but I thought that how I already had the code that was possible to generate that memory matrix…
Now just for my knowledge: It’s possible to generate that data matrix with 1GB RAM memory? The problem could be that due to my company policy our HD are in FAT32? If I use a NTFS HD then it’s possible?
Thanks for your interest,
Marc.

Airport Express Wireless Network Suddenly Stops Working

Hi, I have a wireless network set up with a single airport express using WPA/WPA 2 Personal wireless security. The 5 daily clients on the network are 2 Mac laptops (Both Mac OS X.4), 2 PC's (1 Windows XP and 1 Windows Vista), and an iPhone.
Internet comes in from a Comcast connection directly into the airport express, which is set to create a wireless network and play music wirelessly using AirTunes. The Base station software is up to date, on Automatic Channel selection, and connecting to the internet using DHCP, automatic configuration and sharing a public IP address.
For some reason, every couple of weeks the airport network just stops working altogether. My Macbook Pro shows that it still has a connection with full signal to the network but has no internet connection. When I disconnect and try to reconnect, all attemps to reconnect fail. No other clients are able to get internet at this point, and I cannot even access airport settings from my Macbook Pro unless I manually reset the airport by unplugging and plugging it back in. With this reset the network starts to work again immediately and continues for several weeks again. Does anyone have any idea why it would have this random shut-off every few weeks? Thanks

I have a similiar problem. Every now and then, connecting to my Airport Express network results in "there was an error joining the airport network". It appears to me that this happens at random. Usually, the problem is solved by rebooting to Windows XP using Boot Camp, connecting to the network and then rebooting to OS X.
Recently, it's become worse: the problem persist but sometimes even rebooting to Windows doesn't solve it anymore. When I try to find out what's going on using the Airport Utility, the program tells me "airport utility was unable to find any airport base stations". The only thing that helps in this case is resetting/unplugging my Airport Express and reconfiguring it.
The problems occur independently from the type of security I'm using. It's very annoying and disappointing, since my current high-end MBP has this problem and my previous mac (an iBook) never had it.

VPN Problem: Can't route to other network clients

Hi,
I can't ping the other clients on the network when I'm connected to VPN from outside.
But accessing internet trough VPN works. (Sending all data through VPN).
So in fact, I can only ping the VPN server I'm connected to.
Maybe someone here has an idea what I'm doing wrong here.
Here is my setup:
internet
I
I
Airport Extreme (internal IP 192.168.3.1, Router with NAT Port forwarding to 192.168.3.3)
I
I
Switch----macMini (192.168.3.3, OS X Server 10.4.10 with VPN, DHCP, DNS, NAT enabled)

Other Clients on the Network (Clients have DNS entry 192.168.3.3 192.168.3.1, Router is 192.168.3.1)
The services DHCP, DNS working well for internal clients.
Has someone an idea?
Thanks a lot.

First, ping is ICMP traffic, different from other kinds of (eg, TCP) traffic like AFP.
See http://www.cisco.com/en/US/products/sw/iosswrel/ps1831/productstechnote09186a00800a6057.shtml
traceroute also uses some ICMP traffic but might also be using UDP, see
http://en.wikipedia.org/wiki/Traceroute
http://www.linuxplanet.com/linuxplanet/tutorials/6524/1/
However, in testing, I can indeed ping the server, when I connect to a remote Mac OS X Server via the Mac OS X supplied vpn. But there is no AP Extreme in the path. So the two big factors are: limitations and/or configuration of the AP, and firewall settings for each/any machine involved.
The Airport Extreme is really quite limited, compared to any more full-featured routing device - in terms of just how granular you can be with controlling traffic flow.
(As a total aside, I'd recommend investing in something like a Zyxel Zywall 2 Plus (or similar or better) and running the AP in bridge mode for wireless clients.)
When you've connected via VPN, please run
netstat -rn to see what your default gateway is, that's actually being used.
Finally, what led you to try these tests ? What other problems are you having, what primary issue(s) are you trying to solve ?

Network card stops functioning

After a lightning storm the network card stop functioning.
The windows hardware manager re-installed it after restarting the system but it is not functioning properly.
It does connect to the network but it doesn't send or receive any data packets.
The MAC address has been changed by the windows hardware manager and the card's orange light is constantly on, even if I remove the network cable.

Hi
> MAC address has been changed by the windows hardware manager
This is improbable because in my knowledge the MAC address is fix and cannot be changed.
You said something about lightning storm for me this is a reason why the LAN card does not work correctly.
Maybe there is short circuit on the motherboard
I dont think this could be fixed in the easy way therefore you should contact an technician who could check the notebook to resolve the LAN card problem

Network Environment diadem list of network client

It is possible to get list of network clients through vbscript in Diadem?
Is accessible in Diadem Navigator network environment?
Thanks,
Yustas
Solved!
Go to Solution.

Hi Yustas,
Great, that makes sense now. You can not add a DNS name (\\ComputerName\...) to the list of "grey" folders listed under the "My Computer" node in the tree view of the NAVIGATOR. Any external folders officially mapped by Windows such that they have a drive letter (T: or Z will automatically show up in the list of "grey" folders.
You can add a DNS path to a folder when you create a new "yellow" Search Area under the "Search Areas" node in the tree view of the NAVIGATOR. My recommendation would be to add any folders you want to load data from on these remote computers as Search Areas. This will also give you the ability to look inside those data files without loading them and easily load selected channels, get curve previews, etc.
Ask if you have further questions,

Fms live stream server stops sending data around 4+hrs

Hi,
I am having some issues with fms servers livestream connection. My rtmp client connects to the server ok and rtmp data flowing ok for about 4hours, in the wireshark trace I can see that the server just stops sending data roughly after 4hours. The server version is 3.5.1, and I also try it on a 4.0 server the data stops coming from the server as well after 5+hours. There are no errors or any indication of session disconneciton in the diagnostic logs. I have also looked thru the settings in applicaiton.xml and server.xml I just don't see any obviious reason for the issue. I do send rtmp Acknowledgement to server after the client receives "window size" bytes, and the client sends ping response to server. Are there any other that client needs to send back to server? It would be greatly appreciated for any pointers and help. Thanks.

Updates:
An interesting observation is that the server stops transmitting data when server-to-client bytes reaches ~4G. The number sounds too much like a system resource limitation. It is a live stream and it is not being recorded so I am not sure where is the 4G limitation coming from. FLVCACHE_MAXSIZE is for recorded stream, I think, and it is set to the default 500MB.
Also, in the access log the check point for connect-continue and play-continue keep showing status of 100, which is supposed to be "Waiting for the application to authenticate.". Is this correct? The connection is successfully connected and play command is successful as shown in the access log. swfVerification is disabled in application.xnl. what does the server waiting for in respect to authentication?
Below is the log:

HT1178 Can I just use my airport express as the primary base station and the time capsule as the network client?

I bought a new airport time capsule 3tb to be used to save to file all my pictures. Can I use it as network client and the airport express as the
Primary base station?

To my opinion this looks a bit like what I'm looking for.
At the moment I have an Imac that is wireless connected to a 2TB time capsule (TC1).
To this time capsule I have another 2TB time capsule (TC2) connected via a upt wire connection.
At the moment there is a backup made via time machine from the Imac to the time capsule TC1 (the second TC is not used)
I'm not so technical so I hope you understand the configuration.
What do I want to achieve :
copy all my data from the Imac to TC1 so that the information can be accessed by more users.
create an automatic backup from TC1 to TC2 (mirror or raid system) for security.
give access to some users on the network to access TC1 to read and write data.
TC2 only serves as backup from TC1 and no direct access is needed to this disk.
If there is a solution, thanks for explaining it in 'IT kindergarden style' so that I can understand and use the info.
Many thanks in advance.

Need help regarding Simple Data Client and Simple Data Server VIs

Hi everyone.
I have a simple objective. I just want to test the 2 example VIs, "Simple Data Client" and "Simple Data Server" between 2 computers. I just want to check whether is this working between the 2 computers.
What I have done for now is that I changed the "address", from "localhost" in the "Simple Data Client.vi" to the IP address of the computer running the "Simple Data Server". I runned the "Simple Data Server" VI in one of the computers first followed by the "Simple Data Client" in the other computer. Nothing is received and the client just timed out.
Can anyone please help me troubleshoot and tell me what are the possible problems for this? Are there any wires connections between 2 computers that I am missing or any other configurations I have to make before I can successfully do this?
Thanks.
Regards,
Jonathan

Hi Lee.P.
I understand that. I was just feeling frustrated about the project not working. Sincere apologies from me.
I was wrong about the error number. It is not Error 60. It is Error 59 - The network is down, unreachable, or has been reset.. Yes, I have tried changing the port numbers at the 2 computers when trying to send/receive.
Could anything else be the problem?

Network clients can't log in some days...

but can on others!
Since upgrading to Mavericks and Server 3 I have an issue with local network clients not being able to log in to their accounts some days but can on others (yesterday was fine, today a problem again).
It seems that quite a few people are experiencing similar issues but I can't find a solution I am confident to try out or that replicates my situation.
Before you tart throwing techincal advice at me, I am not a networking expert nor a Mac genius, so please make your explanations clear and simple. Thank you.
I have tried rebooting the server and clients, no success (today - although three days ago that did work);
I have 'unbound' and re bound the clients (which worked four days ago, but not today - they are still showing green light);
I have verified the disk permissions on the server (there were a few errors all bar one are corrected).
Any other (simple) suggestions? Even if it is just things to check and to post more info here to help diagose the problem.
Many thanks in advacne.

I'll try to keep this simple, but network troubleshooting sometimes... isn't.   This reply will also probably get a little wordy.
There are three parts here...
First, ask the server about its own local network and DNS configuration.   Functional networking and proper local DNS being fundamental to how servers work, and how servers can authenticate with your remote clients. To do this, launch Terminal.app from Applications > Utilities and issue the following harmless, non-destructive, diagnostic command — this command will spot most of the issues that can arise with local networking and local DNS:
sudo changeip -checkhostname
The sudo will require entry of an administrative password. There may be a one-time warning displayed about the perils of using sudo. The command will then display some local network configuration output (including the IP address of the server), and finally an indication that either no changes are needed, or that there are network or configuration or DNS errors.   If changes are required, post the output. (If you want or need to obfuscate, please do so consistently here, and please switch the domain part of your host names to "example.com", "example.net" or "example.org".)
Second... On the client systems, launch System Preferences via  > System Preferences..., select Network, select the network connection (WiFi or Ethernet, most likely) that you are using, then select Advanced..., then select DNS, then confirm that the clients are referencing only the IP address of your local OS X Server or whatever DNS server you are using on your local network, and that your client systems are not referencing any ISP DNS servers, Google DNS servers, nor any other DNS servers that are not on your local network.
Third... Please also describe your network configuration in just a little detail.   For instance: are you using an all-wired Ethernet network, or are you using WiFi, or some combination of WiFi and wired networking?   Are you using a firewall? Any network switches? Do you have more than one switch?
If you are using WiFi for your connections, are you located in an area where there may be nearby WiFi networks?
