How to replace the certificate of Cisco 2106 wireless LAN controller for CAPWAP ?

I have interested in CAPWAP feature and I download the open capwap project to make Access Controller (AC) and Wireless Terminal Point (WTP). I had built the AC which used PC and WTP which used Atheros AP. The CAPWAP feature work well when I enabled the CAPWAP that used my own AC and WTP. When I got the Cisco 2106 wireless LAN controller (Cisco WLC), I configured the Cisco WLC to instead my own AC but I got the authorize fail in Cisco WLC side. It seem the Cisco WLC could not recognize the CAPWAP message which sent form my own WTP. I think this issue just need to synchronize the certificate between Cisco WLC and WTP.So I need to replace the Cisco WLC's certificate manually. Does anyone know how to replace the certificate manually with Cisco WLC ?
Best Regards,
Alan

Unfortunately this Support Community is for Cisco Small Business & Small Business Pro product offerings. The WLC2106 is a traditional Cisco product. You can find this type of support on the Cisco NetPro Forum for all traditional Cisco products.

Software Version Upgrade for Cisco 4402 Wireless Lan Controller

Hi,
We have Cisco 4402 Wireless Lan Controller with Software Version 3.2.171.6 and we want to upgrade it to latest version.
So can anyone please let me know the latest version to upgrade the WLC?
Also since WLC is running on very lower version is it possible to upgrade to the latest version directly or we have to move it step by step to upgrade this to latest version?
Thanks

Take a look at the compatibility matrix below:
http://www.cisco.com/en/US/docs/wireless/controller/5500/tech_notes/Wireless_Software_Compatibility_Matrix.html
7.0.235 is the latest that you can go to:
http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn7_0_235_0.html
The release notes outline the upgrade process.
"Upgrade to 4.0.206.0 or later 4.0 release, then upgrade to 4.2.176.0, before upgrading to 7.0.235.0."

AIR-CAP3501I access point not joining the Cisco 2100 Wireless Lan controller.

Hello All,
I am installing a new LAP (AIR-CAP3501I ) through the wireless lan controller (AIR-WLC2112-K9) with software version 7.0. I have an external ADSL modem which will act as the DHCP server for the wireless clients and the LAP.
Please find my network setup as below:
The ISP ADSL modem , WLC and LAP are connected to a unmanaged POE switch. The LAP gets its power through the POE switch. When i connect the LAP and the WLC to the switch along with the ADSL modem, the LAPs are getting the ip address from the ADSL modem, however they are not joining the WLC for further process.
ADSL Modem ip address: 192.168.1.254
Management ip address on the LAP: 192.168.1.1 ( Assigned to port 1, untagged Vlan).
Ap Manager ip address: 192.168.1.1 ( Assigned to the same port i.e port1, Untagged Vlan).
The LAP is getting an IP address from the ADSL modem in the range of the DHCP scope.
I will paste the logs very soon.
Please let me know if i am doing anything wrong oe what will be the issue.
Thanks in advance,
Mohammed Ameen

The Acess point joins the Controller for 2-3 seconds and then unjoins again. I am not sure what i am doing wrong here. The access points are getting the IPs from the ADSL modem through the switch, then it talks to the WLC, however it does not join the controller for further process.
Note:
The Managemnet interface and the AP manager interface are assigned to the same port 1 with unassigned Vlan as mention above.

Certificate Signing request on Wireless LAN controller

Does anyone know how to generate a Certificate Signing Request on 5508 controllers running 7.0.116??

it can't be done on the WLC itself, you need to have OpenSSL on a seperate device. Check the following link for a walk through

Cisco Wireless Control System need wireless Lan Controller ?

Cisco Wireless Control System need wireless Lan Controller , for Rogue detection

Hi Joao,
The WCS is used in conjuntion with the WLC (Wireless Lan Controller) for Rogue Detection. It is not a must for this function but more of an add-on :)
The Cisco WCS is an optional network component that works in conjunction with Cisco Aironet Lightweight Access Points, Cisco wireless LAN controllers and the Cisco Wireless Location Appliance.
From this doc;
http://www.cisco.com/en/US/products/ps6305/index.html
Overview of WCS
The Cisco Wireless Control System (WCS) is a Cisco Unified Wireless Network Solution management tool that adds to the capabilities of the web user interface and command line interface (CLI), moving from individual controllers to a network of controllers. WCS includes the same configuration, performance monitoring, security, fault management, and accounting options used at the controller level and adds a graphical view of multiple controllers and managed access points.
WCS runs on Windows 2003 and Red Hat Enterprise Linux ES 4.0 and AS 4.0 servers. On both Windows and Linux, WCS can run as a normal application or as a service, which runs continuously and resumes running after a reboot.
The WCS user interface enables operators to control all permitted Cisco Unified Wireless Network Solution configuration, monitoring, and control functions through Internet Explorer 6.0 or later. Operator permissions are defined by the administrator using the WCS user interface Administration menu, which enables the administrator to manage user accounts and schedule periodic maintenance tasks.
WCS simplifies controller configuration and monitoring while reducing data entry errors with the Cisco Unified Wireless Network Controller autodiscovery algorithm. WCS uses the industry-standard SNMP protocol to communicate with the controllers.

How to replace the string in a file

Hi, I have a file which contains the following data
File.dat
<file>
<filenum>
W10
</filenum>
<hello>Heading </hello>
</file>
I need to replace the contents of file.dat
database sequence value (for example xx_seq.nextval)
Can some one please tell me how to search this <filenum>
W10</filenum>
and replace this with xx_seq.nextval
and write the entire contents of the file to new file
I am doing some thing like this
suppose if my database value returns 11 from the above sequence then
the output should be in file2.dat as
<file>
<filenum>
11</filenum>
<hello>Heading </hello>
</file>
declare f_in utl_file.file_type;
s_in varchar2(10000);
string1 varchar2(32000);
x number;
begin
f_in := utl_file.fopen('SAMPLEDIR','input.txt','R');
f_in1 := utl_file.fopen('SAMPLEDIR','input1.txt','W');
select xx_seq.nextval into x from dual;
loop
begin utl_file.get_line(f_in,s_in);
EXCEPTION
WHEN NO_DATA_FOUND THEN
EXIT;
string1:= string1 || s_in;
utl_file.put_line( (f_in1,s_in);
end;
end loop;
utl_file.fclose(f_in);
end;
In this case it is reading and writing as it is, but unable to replace the sequence value
Can some one please tell me how to do using replace function
Thanks

Qosmio G50-10J: How to replace the Optical Disc Drive (ODD)?

Hello there,
the optical drive of my Qosmio G 50 is not working properly anymore, it reads only some movie-DVDs, but sadly no videogameDVDs at all, so I cannot instal any games.
The warranty has already expired too. So I wanted to ask if it is possible to change the drive myself, if it is then how should I do it, and if by doing it would the laptop be in
serious risk of getting damaged?
I would be very thankful for every tip and every help you guys can give me!!!
Best regards,
a.z.

Hi
In different cases the ODD replacement is not very tricky.
If you want you can check this forum category.
Here you can find some videos how to replace the ODD on different notebook models:
http://forums.computers.toshiba-europe.com/forums/forum.jspa?forumID=115
Here is also a nice Youtube channel which provides the instructions how to replace the ODD:

But maybe the ODD laser lens is dirty. In my case I could solve similar issue cleaning the laser lens using a cotton-wool tip and alcohol.
But be careful doing this!

Satallite A100: How to replace the keycaps?

Is there a manual on how to replace the keycaps after they come off?
My Satallite A100, one year old, lost two keycaps a few weeks ago, and I am unable to replace them, although I have all the (little) parts. It got even worse when some more came loose recently when my little son peeled some off, using the room created by the already missing keycaps.
Thanks!

Hello Mike
Reading your posting I can not understand exactly what is wrong with your keyboard but removing and putting in place keycaps (plastic with written symbol) is not problematic. You must just put it right in place and gently press it down. You will hear click and the keycap will be in the place again.
Under this keycap is placed small plastic mechanism. It contains two small plastic parts. If they are removed from the bottom you can put them inside again. To see how it looks like remove keycap from any other key and see how is it placed.
I have done the same now and with a little bit patience you can put it in the right position again.

How to view the certificate that a component has been signed with?

Hi all,
Been using java webstart deployment for a while so understand how to sign and deploy java applications.
Question I have is how to view the certificate that was used to Sign a jar. For example, if I signed a jar "myComponent.jar" how can I then view the certificate details within this jar. I currently have an old component which I signed with an old certificate and want to view the experation details.
Thanks in advance

You can use command (it will show CN, OU, O, L, etc... and expiration date, of course):
jarsigner -certs -verify -verbose pathToYourJar.jarI'd suggest redirecting output (>>out.txt).

Hi Sridhar,
I would like to Replace the Charecter values with numeric value in my string.
Exp : first in my string I am having the value like this : 'ABCD1234' ( may be any char and num values ), and I want too get it by '99991234'.
So, if i understand you correctly, you want to replace all characters in a string with 9 as in the above example, irrespective of position of the character, if so try with the below code.
DATA: l_str TYPE string.
l_str = 'ASKHSIUDNSBDKJSDH124312431243124saasdfsf'.
REPLACE ALL OCCURRENCES OF REGEX '\D' IN l_str WITH '9'.
IF sy-subrc EQ 0.
WRITE: l_str. "Result will be 9999999999999999912431243124312499999999

You need to populate that field using cmod code. Find out from which table that field is and go to transaction cmod then enter project name and select component radio button then display.
Now select the FM EXIT_SAPLRSAP_001 if your datasource is transactional dataource
EXIT_SAPLRSAP_002 for master data attibute
EXIT_SAPLRSAP_003 for Hierarchies
EXIT_SAPLRSAP_004 for text
then populate code .
After your code then delete data from ods then reinit to populate the enhanced field.
Hope it helps..
