How can I restrict who connects with WPA?
Our current network is using WPA with having the users get authenticated via the windows domain. Anyone with a domain login can use the same credentials to log in to the wireless network.
Is there a way to keep some users from authenticating to the wireless network?
I was not sure if the windows domain had an option to set who can and cannot access the wireless.
What I am trying to prevent is a user installing a wireless card into their laptop,getting the SSID from another user and the accessing the wireless network with permission.
If your company standardizes on a given wireless NIC, you might be able to institute a MAC filter.
If you're using WPA with server-based authentication, you can usually install a policy (i.e., with Microsoft IAS, RRAS, and the user account, you can disable wireless logins by checking / unchecking the "Dial-in" attribute).
Are you using ACS, Microsoft, or freeRADIUS (or other RADIUS server)?
WPA is more of an encrytion thing, which authentication scheme are you using (WPA-PSK, LEAP, PEAP, EAP-TLS, EAP-TTLS, MD5 ...)?
IF you're using Microsoft-based authentication platforms, Microsoft has some pretty good white papers / step-by-step info on setting up their systems.
Good Luck

How can I restrict a vendor with certain value limit?
Hi Gururs,
How can I restrict a vendor with certain value limit?.
Scenario is like this
If my company was decided to purchase goods from a particular vendor upto Rs.1000, if cross the rs.1000 limit don't allow the Posting the PO and get the Message as warning/error.
Give the configuration setting's and T.codes
Thanks and regards
G.N.RaoHi
Go to T.Code oms4 and then select the material status BP (Blocked for purchasing)
Click on Details
In that under Purchasing select the option A= Warning or B=Error
Click on Save
Thus by doing this no further purchasing function for that material can be done. So the PO can not be issued
So as and when the value limit reaches see that purchasing option is blocked
So no further PO are generated in the future
I hope this helps you out
If found useful reward accordingly
Thanks

How can I establish bluetooth connection with my iPhone so I can share and modify my iPhone's contact list on my macbook?
The Mac and iPhone sync with iTunes though the charge cable that is included with the iPhone. Through this, you can sync your calendars and contacts.
Bluetooth is an impractical sync scheme as the time it would take to say transfer your song catalog could be longer than your phone contract. I suppose it is entirely possible to implement with hacks and jailbreaking, but I am fairly sure it is beyond the rules here to discuss such activities.
You may wan tto ask this same question in the iPhone section of the comminitie here. There may be some workarounds for just contacts. -
How can i improve database connectivity with connection pool
Hi,
I used to create a connection to DB per session since the application is pretty small. Now i want to improve the db connectrion with connection pool. However, i am still confused since the book i read says that i have to change something in server.xml in the tomcat server while other people in this forum actually implement a connection pool class. Isnt it has been built into the servlet container? if yes, how can i use it? I suppose i only have to open the connection and the connection pool will reclaim the resource when the session is terminated in the same way the gabage collector reclaim resource when no reference is associated to object, am i correct?
Thaithe documentation for Tomcat 5 DB pooling can be found at:
http://jakarta.apache.org/tomcat/tom...les-howto.html
Here are the Tomcat 4 docs:
http://jakarta.apache.org/tomcat/tom...les-howto.html
The administration console can be found at (under default install):
http:localhost:8080/admin
But, you have to set up a user and password in your
<tomcat-install>/conf/tomcat-users.xml file.
You need to add an "admin" role and a user that will be assigned this
role like this (obviously you won't be using "tomcat" as your password):
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="admin"/>
<user username="tomcat" password="tomcat" roles="admin"/>
</tomcat-users>
So, I can log in as Tomcat and have admin privs.

How can i find tables connected with structure?
hi experts,
i have a problem that i know one structure and i want know that which tables are connected with
that structure.please help.
thanks
Moderator message: FAQ, please search for previous threads dealing with this topic.
locked by: Thomas Zloch on Aug 17, 2010 11:46 AMHi Abhishek,
Just display the structure in se11 and choose the data element of the key field (probably you can choose the first field). then chk with the where used list.
From the list you just search for a suitable table. If you provide the infm on the tcode / structure name then probably we may help you with the table name.
But I request you to first try with yourself.

How can i create wifi hotspot with WPA for windows laptops?
I using Macbook with Mac OS X Mountain Lion. I can't create a wifi network with WPA Protected Access. I can create with 40bit protection access but i can't with windows..
No, not unless Apple introduce it for the iPad 2 in a future iOS update - but until if/when that happens you won't be able to use it as a personal hotspot.

How can I get internet connectivity with my iPod Touch cabled to my PC?
Most devices "tether" to a computer (PC or iMac) for internet connection. I cannot find any reference in the user manual on getting internet access from the connected PC to the "tethered" ipod touch. How can I accomplish this?
Hi,
The iPhone 3G and iPhone 3GS support Internet tethering over a USB cable, as described here: http://support.apple.com/kb/HT3574.
The iPod touch can connect over a Wi-Fi network, as mentioned here: http://support.apple.com/kb/HT2031.
If your PC has a wireless card, you may be able to create an Ad-Hoc Wi-Fi network that can share the Internet access to the iPod touch.
You can also get a wireless router, like an Airport base station http://www.apple.com/wifi/.

Windows 98 does not meet the system requirements. You will not be able to use iTunes and get the iPod+iTunes experience.
You would have to do something like this...

When I connect my iPod Touch to a new laptop (Macbook Air) the "Info" tab won't appear and therefore I cannot sync it with my new iTunes. How can I sync this iPod with the iTunes on my new laptop?
There is no Info tab in Mavericks
if you use OS X v.10.8.5 or earlier. If you use OS X Mavericks v.10.9 or later, your contacts, calendars, and other info are updated on your computers and iOS devices via iCloud. For more information, see iCloud Help at icloud.com.

My laptop died so I've installed itunes onto another PC and my music is all on an external hardive which is connected to the new PC. How can I sync my ipod with the new itunes and get all the music onto itunes?
You might consider itunes match for moving CDs you've copied into your itunes library if you dont have a way to use home sharing.
iTunes match is an optional service offered by apple that costs about $25 a year. It scans your music library and if it finds music that is already in apple's itunes catalog it'll automatically "unlock"/"store" these in the cloud for you. Items that it does not find in the catalog it'll upload and store these in the cloud for you and you can download them on your devices. See http://www.apple.com/itunes/itunes-match/ -
I have iPhone 4. After I upgraded to ios5 I have a problem with Wi-Fi connection with "WPA enterprize" protection. I can define the connection and everything works fine. But after I lose signal or shutoff the WiFi, I cannot re-connect, and need re-define the net. It is only in WPA enterprize.
Thanks,
EyalI tried this! Somebody suggested it in another thread. It did not work, sadly.

How can I restrict the total no. of recs. per physical page
Hi !
I have created a report and I am saving that in a text file. The
problem is that when I try to take the output on the printer
then the total no of records overflows to the next pages and the
next page heading comes much below to it's designated place.
Max.no of records property in the repaeting frame is for the
logical page.
How can I restrict the max. number of records per physical page ?
Any pointer will be welcome,
Thanks in advance,
Shobhit
nullJust for fun (and in case this wasn't done to death in the other thread), the rule posted here states:
Most years have 365 days, but a leap year has 366 days. That adds up to 52 weeks (where each week is exactly 7 days) PLUS 1 or 2 additional days. The year 2012 has exactly 366 days.Now if the year starts on a Sunday in a non-leap year, you end up with 53 Sundays. Or if either of the first two days lands on a Sunday during a leap year, then you can also get 53 Sundays.>
which allows a calculation like this:
with test_data as
( select rownum + 1999 as test_year from dual
connect by rownum <= 15 )
select test_year
, case
when first_day = 'SUN'
or ( first_day = 'SAT' and leap_year = 'Y' )
then 53
else 52
end as sundays
from ( select test_year
, to_char(to_date(d.test_year||'-01-01','YYYY-MM-DD'),'DY', 'NLS_DATE_LANGUAGE=ENGLISH') first_day
, case extract(day from last_day(to_date(d.test_year||'-02','YYYY-MM'))) when 29 then 'Y' else 'N' end as leap_year
from test_data d );
TEST_YEAR SUNDAYS

How can i do the RAC with Oracle 9i ?
How can i do the RAC with Oracle 9i ?
The Oracle 9i has a RAC(Real Application Cluster)module , please who can tell me how can i let it working .
Which hardware the RAC need's
Thank All ,
[email protected]That is right you need atleast 2 boxes. The two servers will use the same hard disks.
The concept is an extension of OPS(Oracle Parallel Server).
Basically, you install Oracle Server Software on both the boxes, One database will be shared by both the servers. You can access your database through the Server1 or Server2. If Server1 fails then the Server2 will take over all the connections. You can add or remove any servers to and from the cluster any time you want with out impacting your production.
They share load, reliable, scalable.... -

This seems a more user friendly option for thoes who are not ofay with IP addresses etc.
