SNMP Discovery of clients through WLC problems

I have a client with a 2112 WLC and 1252AG radios. The clients work fine, but an SNMP management server can not reach any of the clients over the wireless. Before the WLC and new AP's were installed, they were running older Cisco Autonomous AP's and had no problems with SNMP. My monitoring system uses SNMP and it can reach the WLC just fine, so there doesnt appear to be any issues on the switched network.
What can be blocking the SNMP on the WLC?

the WLC, by default doesn't communicate when you bridge the VLANs. Do the clients need to be in the same subnet as the SNMP server? If not, remove the interface and they should be able to communicate.
If they do need to hVe in that subnet, then you need to enable management via dynamic interface

802.1x auth fail through WLC but OK on autonomous APs

Hello,
I migrate 1310 APs from Autonomous to Lightweight. Migration is OK with Cisco Upgrade Tool, and AP are registered on my 2504 WLC.
Previously, a 802.1x network was broadcasted by autonomous APs, supplicants were identified on a freeradius server with MSCHAPv2/PEAP method.
I send you in attachement a AP config which is OK.
But on the WLC, supplicants can't auth on Radius server.
I configured a WLAN with WPA/TKIP/802.1x with my radius server in AAA tab.
When clients try to authenticate, I get these messages where xxx is login:
AAA Authentication Failure for UserName:821 User Type: WLAN USER
AAA Authentication Failure for UserName:200 User Type: WLAN USER
AAA Authentication Failure for UserName:209 User Type: WLAN USER
Security info on client page is:
Security Policy Completed
No
Policy Type
WPA
Encryption Cipher
TKIP-MIC
EAP Type
PEAP
SNMP NAC State
Access
Radius NAC State
8021X_REQD
What is strange, there are some clients which are OK in RUN State, and 50 other % which are not.
In attachment there is a debug client "mac-address" on a device which cannot authenticate through WLC.
Thank you,
Clement

Hi Amjad,
I'm not using NAC.
Clients makes a MSCHAPv2/PEAP auth on a FreeRadius server through the WLC.
Because network is critical, I do a rollback so I passed the light APs into their autonomous original state.
Now all clients can successfully auth on the network. I don't understand what happens when APs are in lightweight mode :/
I have more information about the WLAN clients :
- Each client is an infrastructure which have a AXIS wireless modem in bridge mode, which is client of the WLAN. This modem have login/password for MSCHAPv2 auth.
- Behind the AXIS, there is a switch on which 4 devices in static IP are connected.
- If the AXIS is successfully authenticated on the WLAN, only one device of four is able to ping servers on the LAN. The others cannot, it seems to be a "token ring" like ?!
The WLAN clients infrastructures are very proprietary, it's very difficult to debug.
What I know, is all clients are OK on autonomous AP (auth 100% successfull, ping 100% successfull for 4 devices) and when the clients join a lightweight AP it is (auth 50% successfull, ping 100% successfull for 1 device, 0% successfull for 3 others devices)
Tell me if you need specific debug logs.

Facing issue while trying to disable automatic discovery of devices through Apple Bonjour

Hi All,
I am facing issue while trying to disable automatic discovery of devices through Apple Bonjour.
Background: Whenever our application is in running state, devices are automatically discovered if it connects to PC. We are using Apple Bonjour's auto discovery technology( mdnsresponder ).
We are registering a particular service type by using DNS API "DNSServiceRegister". Service type is getting registered properly and we are able to discovered that particular type of device.
Platform: Windows 7.0 / MAC 10.8
Issue:
But we are facing issue while trying to disable auto discovery of a device programmatically. i.e, unregistered a service reference programmatically from our windows application.
To unregistered a service we are using "DNSServiceRefDeallocate" DNS API. But looks like it is not working properly.
Is this DNS API “DNSServiceRefDeallocate” is correct one to unregistered the service?
Here is the step by step procedure that we are following to de-allocate a service reference:
1.Browsing / Query a service by using service type to get service reference (DNSServiceRef).
2.Get reference socket FD by using DNS API "DNSServiceRefSockFD".
3.Select a socket by using "select" API.
4.Close the socket that we got from step 2 by closesocket().
5.Delete the service reference by using DNS API "DNSServiceRefDeallocate" and service reference from step 1.
Are we missing any step to unregistered a service?

Goutam

Original problem I noticed was that regular websites I go to (such as msn) were only partially downloading. I could see the text on the site but no pictures or videos. All web surfing was extremely slow. When I would go to a site such as man I would see another address in the lower left corner for "ads1.msads.net" or "cdn.optimizely.com" that is was trying to connect to. I tried using all three of my browsers (firefox, safari, chrome) and got the same response on all browsers. After I spent some time researching the issue I decided I probably had a adware/malware problem so I decided to try adwaremedic.com. I could also not access that site along with thesafemac.com or apple.com. I was also getting the same response on my other devices (iPhone, iPad, and a mac air). I could not access any of these sites on any of my devices although I could get to almost any other site although it was very slow. At that point I decided to unplug the router. I also did a number of other things before then to try and manually get rid of any adware. Eventually I got msn back working, apple.com, and the speed was much faster. But, I still can not access adwaremedic and thesafemac.com. I could access these on my phone with 3G but not on my wifi. This is where the problem still stands. I am sure I still have some adware on my computer and need to find a way to remove it. I am no techie so the complicated manual fixes are difficult for me to do.

SNMP Discovery of Windows machine

I'm trying to install and configure the Netbackup management pack, which ultimately requires that you discover the windows machine that runs the Netbackup NOM Console as an snmp discovered device.    (the netbackup pack is essentially a trap converter).
My problem is that I cannot seem to discover the windows server using the snmp discovery wizard.   It just times out and says that the device was not discovered. I have discovered other SNMP devices, but this is the first time I've tried to discover a windows server via snmp. Here's what I've tried and/or verified:
- SQL Broker is enabled
- SNMP service and snmp trap service are set to automatic start and are running
- SNMP community strings are all "public" with read/create on both the NOM machine and the management server.
- "Accept traps from all hosts" is enabled.
- I've tried both snmp v1 and v2 discovery in the wizard
- I have verified that there is NO port blocking between the agent and MS. (using the portqry utility).
- Ping responses are successful to/from both nodes and name resolution also works fine.
I've found several forum postings about snmp discovery and everything seems to be set correctly.
Any other bugs or known issues about discovering windows server via snmp?   anyone every successfully deploy the netbackup management pack?
Thanks
What Gives?

John,
Couple things - I think since I posted this thread that Symantec has released a newer version of NOM and the Netbackup management pack that had a couple fixes.      The SNMP blocking issue was caused by the NOM Server service and I believe there was a configuration section in the NOM console that allows you to change NOM's snmp port so that the Windows SNMP service can use port 161.
Even after making this change, I found that the Netbackup discovery views were not getting populated.   I found that the designated management server that the nom server was focused on was generating the following WMI error and I found that I had to add the default agent action account into the local administrators group of the NOM server.   This allowed the WMI queries to complete and allowed the discovery data to populate.     Other than this, we just defined the alerts in NOM that we wanted to be notified on and chose SNMP as the delivery mechanism - then the alerts showed up in SCOM.       Please note that the nom/scom integration components do no maintain state information - it's really just a basic SNMP trap forwarder.   So you will have to manually close any alerts that come from NOM into scom.

Duplicating de confirmation for Clients with credit problems

Hi,
We are using GATP to confirmed the sales orders quantities. In the check instructions,
we are using check availability and then RBA (product substitution)
When I create a sales order for a client with credit problems the confirmed quantity
is being duplicated after releasing the order.
The steps I am following are next:
1.        VA01: create sales order (i.e: order product D 10 PC, I got 10 PC of product E confirmed because of the RBA)
2.        VKM3: Release the order
3.        VA03: display the sales order
(it duplicates the lines with confirmed quantity - i.e: I got line 10: product D 0 PC confirmed; line 11: product E 10 PC confirmed; line 12: product E 10 PC confirmed, so line 12 is repeating line 11)
We have explore any issues related to the availability check, but it seems to be a problem with the configuration of the credit processing.
Have you ever had this issue? Any recommendation to solve it?
Thanks a lot in advance.

777,
Are you using product allocation?
In what case you see duplicate confirmation? in case of partial delivered order? if so check OSS note 1442425.

Harshil Desai

Error installing MBAM client through SCCM task sequence error code 80070005

Hi
I'm getting a weird error when trying to deploy the MBAM 2.0 client through a task sequence, it was working but now keep seeing the below two errors in the AppEnforce log, after it has returned the 3010 soft reboot code.
CoCreateInstance failed on CLSID_ProductSrcUpdateMgr, error 80070005
Failed to update msi source list, error 0x80070005
does anyone have any idea what these mean?
thanks
Mark

What is the silent installation command line for MBAM client you are using. I would suggest to first test the silent installation manually and test whether it is working successfully or not.
Are you using the msi installer or the setup.exe

How can SAP tRFC server tell client through JCo that function carried out?

SAPs "Transactional RFC Technical Description" document (release 4.0) says in section Transactional RFC on page 6: "Finally, the server tells the client, that the function has been carried out and the client acknowledges this.".
How can the server tell this to the client when the server communicates with the client through JCo (Java Connector)?

System.out.println goes to console, which is not a file... This whole thing is much easier if you use standard logging:

Please read any moderators or anyone that has been through these problems.

Hey everyone,
I hope a moderator or someone who understands this stuff more than i do reads this post. I understand many of us are going through these problems, but since I've been through hours of tech support, driven down to the apple store near me (2 hrs away) 3 times now and talked to numerous "genious bar" employees about this and searched these forums for answers for long enough, i thought id share my problem with anyone who will listen because ive tried everything else.
I bought my iPod (5G 30g video) a week or so ago and before i could even put a song on it, i downloaded the update and it crashed. symptoms include: loss of backlight, the font becomes very small and the color turns to black and white, and then eventually i get the dreaded "www.apple.com/support" screen frozen on my iPod.
the second time i took my broken ipod into the apple store, someone found out my ipod was programmed for a Mac (im on a windows xp PC). he rebooted my ipod and got it to dl music and return its color/backlight when he plugged it into the Mac.
I took it home and did the steps he told me to do in order to reprgm mine to a Windows. But when i try to "Restore" my ipod like he suggested, i get the "Firmware update error" message and the iPod crashes again and loses the backlight/color and ultimately just shuts off.
I FINALLY got some answers my third trip to apple store where someone took my pod back to their windows computer in the back and for sure reprogrammed it to operate with windows. he said my ipod was fine and even put a few songs onto it to test out.
I took it home and actually got it to work. I put a few hundred songs on it and finally got to spend one day with a working ipod. it ruled.
But today I turned on iTunes and was gonna put more music on my pod, and i noticed that suddenly my iPod's name in the iTUnes menu had been changed. I clicked on it to see if all my songs from the previous day were still in it, but they werent. it was all gone. I have no idea why it changed the name of my ipod and erased all the memory. I never attempted to change the name of ipod, it just happened by itself...
I tried to just dl all the music back onto the newly erased pod, but my computer said it couldnt read the (newly named) ipod and to do a "restore"
When i tried to restore..."Firmware update error" and the ipod crashed for the 10th time.
Im speechless at this point and am desperate (as we all are) for answers. If anyone made it through this long post and has any suggestions or answers, please help.
And Apple forum moderators, please take note of this and help because at the moment im extremely dissapointed in the apple support (the guy at the apple store actually denied the fact that windows ppl are having trouble with the new update and said it was only me basically). I heard that apple support was among the best, but Ive spent the better portion of my last week trying to get my brand new ipod to work and so far, no one has any answers.
Thank you all for reading this and i really appreciate the responses,
B

Welcome to Apple Discussions!
Make sure that all software is up to date...
iPod Updater Download Page
iTunes Download Page
If they are restoring with the latest update and you don't have that on your computer, there could be problems.
Also, know that you could have called instead of driving there that many times...

Problem in downloading a file from AS to client through form using webutil

I am running oracle 10g sever & devloper 10g in the same machine. Almost every thing is working properly from a client PC in the network except the following aspect :-
From client pc, through form, I have created one export(dmp file) which is being saved in the AS. Now I want this file to be downloaded from AS to this client PC.
I have tried webutil_file.copy_file(server_filename,client_copy_name) which is not working. the error trace file says "Unable to open source file in server" & "Unable to read WebUtil configuration file".
I have also tried webutil_file_transfer.AS_to_Client_with_progress
which results in unsuccessful from server to client.
I modified the webutil.cfg file as :=
transfer.database.enabled=TRUE
transfer.appsrv.enabled=TRUE
transfer.appsrv.accessControl=FALSE
transfer.appsrv.workAreaRoot=D:\temp
transfer.appsrv.read.1=D:\temp

Problem while sending ByteArray from as3 client through netconnection call method to red5 server

Hi to all,
I'm trying to send from as3 client a ByteArray of more or less 3 MB using NetConnection's call method but I am unable to do it, cause I get a timeout on the server and the client get disconnected (I have also increased the timeout limit in red5.properties but nothing changed). If I try to send a smaller ByteArray I don't have problem, even if the trasfer is really slow.
Any solution?
thanks

put it in code tags so it's readable
CLIENT
public void sendLoginData(String data)
int c=0;
byte loginData[]=new byte[data.length()];
loginData=data.getBytes();
try
out.write(loginData);
System.out.println(client.isClosed());
// here i want 2 receive the 1 byte data whch i hv sent frm server's RUN() method
//following code is not working :( it gets hanged
while((c=in.read())!=-1)
System.out.print(c);
System.out.print("hi");
catch(Exception e)
System.out.println("Caught:" + e);
finally
out.close();
}SERVER
public void run()

WISM and NAC OOB/ Client in a different WLC problem

Guys,
I am using two WiSM modules in 6513 Chassi.
We have 3 SSID configured but on each WLC are using APGroups making a Layer 3 roaming.
Well, Everything is work out fine and we have hundreds of the connections per day but each day appear two or three clients that still on Quarantine mode and the WLC does not change Auth_vlan to Access_Vlan.
NAC appear that client as ONLINE on WLC 3 but that client isn't there, he is on WLC 2 in Quarantine mode.
anyone know can help me?
thanks a lot

I think the jndi service can be accessed froma remote m/c, you can initialize the context with the appropriate paramters, so the lookups on the topic and connection factories and continue with your work.
