Hi Mahesh,
Try running nmap against your switch: http://nmap.org/nsedoc/scripts/ssl-enum-ciphers.html
nmap --script ssl-enum-ciphers -p 443 <switch_name>
There is an open Cisco bug for this vulnerabilty:
https://tools.cisco.com/bugsearch/bug/CSCur23656
...which implies that this vulnerabilty is not fixed in any version of IOS!? If you are concerned, use the CLI and drop the HTTP(S) access.
cheers,

How to check if column_ name is used by any procedure ,package ,function

Help Is greatly appreciated .
Kindly please let me know for the folllwoing:
How to check if column_ name is used by any procedure ,package ,function ,trigger or in any dataabse objects

In general you can't. Code can always exist outside the database and it is always possible that you have dynamic code and there is no way to find references like that if used by dynamic code. That dynamic code reference could be based on a query stored in a table.
And there is no way of knowing if external code (e.g. a Java app) references that column.
Another issue is that a column could exist in multiple schemas and in multiple objects of different types in those schemas. So a global DB search for 'MY_COLUMN' might turn up references in multiple schemas and you may only care about one schema.
Unfortunately a reference to 'MY_COLUMN' in code could refer to many different objects or to an object in different schemas so how would you resolve those? Especially if you take synonyms into account which can ponit about anywhere.
Why don't you tell us what it is you are really trying to do?
Are you trying to find the references to a particular column? Why? Are you planning on removing/renaming the column? If so then the simplest way is to remove/rename the column and see what objects become invalid. Those invalid objects will have become invalid because that column is no longer available.
As suggested you can use DBA_SOURCE for references in code that use the standard names. But for tables/views you need to use all_tab_columns. And for dynamic code or client code (e.g. a Java application) there is no way.

How to check paragraph in Reader document using API?

Hi,
When I extract the content of the PDF (Reader) document through .Net code, I could see only carriage return character ('\r') when it's a new line.
But with '\r' character, I can not say whether it's normal new line or it's a paragraph.
Please let me know if Adobe has got any API which can show how to differentiate between 'a new line' and 'a paragraph'.
E.g.:
Test Test Test
Test Test Test <- I can easily say it's start with a new line.
Test Test Test Test Test
Test Test Test Test Test Test.
Test Test Test Test Test <- This is a paragraph but how to check from the code?
Test Test Test Test Test Test
Test Test Test Test Test Test.

We use 'PDDocCreateWordFinder' , 'PDWordFinderEnumWords' to extract the text from Adobe Reader document through Code, Not tool.
But, by using these APIs, I can't see any difference in 'new line/row' or 'paragraph' if exists in PDF doc.
I need such API which can give the exact format of Adobe Reader doc according to the content exists in that PDF doc.
Thanks!

HOw to check for the Child Elements USing only SAX Parsr?

HI Guyz,
How to check whether there are any Child Elements in an XML file using ONLY SAX parser ??? I have a requirement of checking first whether there is any Child Elements exists for a Element or not and based on that I have to take certain actions. Can anyone suggest me How to do that ???
Thanx
KK

Since SAX is event controlled, you wont know if there's a child element unless you actually bump into it with the Parser. You'll simply get another startElement event after your current one.

How to check files in the directory using JSP?.

Hi,
How can i check the file is directory or file and readable or writable and file size and type of file(Ex. jpg, txt, doc., etc). i want to list the specific type of file in the particular directroy.. please help me..
Regards
CHinna

With the File class, using the methods isFile(), isDirectory(), canRead(), canWrite(), length() and getName()
With File.listFiles() you can get a directory listing. If you want to limit the amount of files returned, you can pass your own FileFilter to it.

How to check whether database is in use or not

hi,
i have written a program for taking backup of database file(ACCESS).
i can able to zip it successfully, but i have to check before zipping that
whether it is opened or closed(using by any other).
How can i do it.I am not getting idea. please do help
Thanking you in advance
regards
shashi

I don't know if this is possible. Since you have access to the file system and know the Access MDB location, look to see if the Access lock file exists. It's usually in the same location as the MDB and has the same name with an LDB extension

How to Check In as facebook status using an Nokia ...

Can I do it on my Nokia E72? is it really that difficultfor you guys to develop? I have tried but I cant...there is a check in icon on FB but when I click on it it doesnt show any location. I think you have not been able to sync the FB check in button with your gps in the phone. Hope you would have worked out something by now...or sadly I will have to chuck my e72 for a BB or iphone. Thats really sad coz i have been using a nokia phones only since 2001.

Sorry if you mean something else, but just open the Nokia Maps and select 'Check In'.. It will ask whether to 'Go Online to use service?' Select 'Yes'.. You may need to sign in using the Nokia Account. Now it should show you the places nearby..Select the appropriate. In the next step, tap in the square box with 3 dots and then select 'Facebook' and then 'Done'. Now a square with the facebook logo displays at the bottom.. Tap on 'Check In'.. and you are done..

How to check my Oracle dbms is using ASM for storage?

Thanks.

On unix first check whether you have any ASM instance or not by:
ps -ef | grep pmon
It will show you an entry similar to:
oracle 6953 1 0 Jun24 ? 00:00:07 asm_pmon_+ASM
which means you are having ASM instance on the box, next to find out whether a DB is using it or not login to that DB and issue (from sqlplus):
SQL>select name from v$datafile;
If any of the datafile path is starting from a "+" sign it means you are using ASM diskgroup for that file.
You can also issue:
show parameter db_recovery_file_dest
to check if the flashback area of your database is sitting on ASM or not.

How to check if Connection Pooling is used in our application

We have an ASP.NET application designed by developer team.
All the files are .aspx
They are all hosted in an Windows IIS and connect to Oracle database.
I was reading some forums where people are suggesting to use "connection pooling" for better database performance.
Now is there anyway I can check in code of the .aspx files to see if our team is using connection pooling method or not.

Connection pooling is on by default. The easiest way to check is to check the connect string. If "pooling=false" is there, it's been turned off. If "pooling=true" is specified, or if it's not specified at all, it's on.
Hope it helps,
Greg

How to check if assignment is in use?

Hi,
before exporting a document to pdf I'm running few checks on links (if out of date or missing etc...). But I realized that you can have inaccessible assignment which is a little bit harder to find. Can anybody help me with this one... is there a way to check if the assignment is "in use" beside checking if lock file of assignment file exists?
The thing is that in some kind of workflow you could export document to pdf without knowing that someone else is still holding a piece of text in InCopy. Browsing through links is not helpfull with this situation.
TNX!

Marko

TNX!
This one works fine. Here is VB version also:
        'Check for Locked Stories
        For storyCount As Integer = 1 To myApplication.ActiveDocument.Stories.Count
            Dim myStory As InDesign.Story = myApplication.ActiveDocument.Stories.Item(storyCount)
            If myStory.LockState = idLockStateValues.idLockedStory Then
                Dim myStoryContent As String = myStory.Texts.Item(1).Contents.ToString
                MsgBox("Locked Story: " + vbNewLine + vbNewLine + myStoryContent.Substring(0, 100) + vbNewLine + vbNewLine + "Exiting...")
                Exit Sub
            End If
        Next
Thanks once again!
Kind regards,

How to check whether Java 3d is using hardware acceleration?

Hi
I just started looking into Java3d api. I am going through the tutorial examples. When I run it on Windows with JDK1.4.2, the app runs, but taskmanager shows cpu usage is around 55% of my 3GHz Intel processor.
I am sending the following VM parameters
-Djava.library.path=C:\progra~1\Java\Java3D\bin -Dj3d.rend=ogl -Dj3d.debug=true
I tried Direct3D as well by passing -Dj3d.rend=d3d. I don't see much difference in cpu usage. The sample I am playing is the one where you create a ColorCube and rotate it on a timeline. Pretty straight forward code taken from the tutorial.
I am wondering
a) Why is my cpu at 55% if it is using h/w acceleration?
b) Is there any way to find out whether Java is using software renderer vs h/w renderer.
I used sys internals processexp tool to look at the stack of java thread that is spinning the cube. I don't see any references to opengl or j3d dlls in the call stack.
I appreciate ur help.
Thanks

How to check which privileges user is using

Hello All,
I have a user assigned DBA role in mistake many years back.
During our security overview I is flagged and now I need to revoke the DBA role from that user.At the moment it look like as follows and I am on 10204 database
Privilege
Category Granted Privilege
Role Privs CONNECT
DBA
OEM_MONITOR
RESOURCE
Sys Privs ALTER ANY MATERIALIZED VIEW
ANALYZE ANY
CREATE ANY MATERIALIZED VIEW
CREATE PROCEDURE
CREATE ROLE
CREATE SEQUENCE
CREATE SESSION
CREATE TABLE
CREATE VIEW
DROP ANY MATERIALIZED VIEW
GLOBAL QUERY REWRITE
UNLIMITED TABLESPACE
Now I need to find what all privileges out of approx 158 in the DBA role this user is using so that I can revoke the DBA role and assign that sys privielege exclusively and later on trim down a bit on those as well if possible?
Can someone help me in finding or is there a way possible to find out which privileges are actually being used by the user assigned to him via DBA role?
I can find something on net on those lines, any help or useful pointers would be highly appreciated.
Many Thanks,
Rishi

Hello All,
Right I think auditing the DBA role could save my day.I have enable the auditing on the DB for dba role as shown below:
audit_file_dest string /oraadmin/tgtx/10/adump
audit_sys_operations boolean FALSE
audit_syslog_level string
audit_trail string DB, EXTENDED
Exact version of the database is:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - Prod
PL/SQL Release 10.2.0.4.0 - Production
CORE 10.2.0.4.0 Production
TNS for Linux: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - Production
I have enable the audit dba role for user exeter as shown:
SYS@TGTX> AUDIT DBA by exeter WHENEVER SUCCESSFUL;
Audit succeeded.
Now I expect to audit all the sys privs assigned to dba role but alas its not working as expected if anyone can shed any light ON it, what I am trying to do is as follows:
I am trying to use the sys priv that is create any table as user exeter who is assigned dba role as follows:
SYS@TGTX> select * from dba_role_privs where grantee='EXETER';
GRANTEE GRANTED_ROLE ADM DEF
EXETER DBA NO YES
EXETER CONNECT NO YES
EXETER RESOURCE NO YES
EXETER OEM_MONITOR NO YES
EXETER@TGTX> create table dbaschema.test2 (srno number(10));
Table created.
Now I expect to see some records in dba_audit_trail as a result of above commands but there is none, am I doing anything wrong here?
SELECT * FROM dba_audit_trail
WHERE USERNAME = 'EXETER'
ORDER BY timestamp;
No rows returned but I shall have expected atleast one row to be returned here after enabling the audit on DBA role by exeter.
Any Ideas?
Thanks
Rish

How to check where a table is used in other programes

Hi all,
I am facing one problem... there is a z-table created long back and still being used to store data.
There may be some transactions to fill / update this table. Those programs are not coming in where-used list.
As per the requirement, i already have one transaction to fetch data from this table... but this program is also not coming in the where-used list. So it means there might be some other programs also which are using this table.
So please help me in finding such programs.
Thanks,
Sujeet
