"Invalid CMS Connection" Error during DS 4.2 SP2 Installation

Question

Hi Everybody,
  Can anyone shed the light on the following dead end issue we are facing during Data Service 4.2 SP 2 Add On the EXISTING BOBI 4.1 SP2
  ( compatibility is confirmed by SAP through OSS Incident).
  Environment :
  Existing  Distributed Architecture of BOBI 4.1 SP 2 i..e CMS DB Oracle on One Host and BOBI 4.2 SP2 on Another Host
  Adding :  Data Services 4.2 SP2 on Separate Host
  OS :  Linux RED HAT 6.3 (VMware)
  At the initial Information Gathering Phase of   Data Services Installation I  face the following issue at the section of  " Enter CMS Name " :
   - We entered Physical / Virtual server name   with and without FQDN  i.e. Current CMS Host
   - Next is Admin and Password  i.e. Administrator and Password of Existing CMS
We get the following System Response / Error :
Invalid CMS Connection Information.
Installer could not detect a running Data Services Administrator Service with
the specified CMS connection information.
and no valid local SIA node was found.
Installer can not continue.
Please fix this problem by:
1. Making sure a Data Services Administrator Service is up and running with the specified CMS;
2. or creating a valid local SIA node to point to the specified CMS.
  It seems this is Known Issue and I  see two notes :
1837296 - ERROR: No valid local SIA nodes exist for the given CMS connection information - Data Services 4.x
                   - Not applicable as this is for IPS based installation
1682686 - Cannot connect to the CMS during installation of Data Services or Information Steward
                   - This note suggests to enter the TEMP variable pointing to location of Log Files Storing the Installation Logs
                      accordingly we did set " export TEMP=/usr/sap/<SID>/BOBI  "  as Temp variable but same error persists with the same message !!
                   - This note says valid for " DS 4.1 "
                         ..seems SAP Fall behind with the Rapid Frequency of  DS Releases and even in this note there's extremely brief so called solution
                         ...Defining TEMP should solve this issue in this case as per the note but, it is not solving issue at all !!
In addition to define TEMP Variable to resolve this, following verification, further attempts are made to fix it :
#1. I am able to ping from Data Services Host to CMS Host and there's no Firewall blocking this connection
#2. Using IP in place of  Host Name ( FQDN or without FQDN ) does NOT resolve
#3. With Administrator / Password mentioned - log in is possible
#4. Added entries in /etc/hosts of CMS Host and in DS Host ( cross entries )
#5  There's a Thread -
              http://scn.sap.com/thread/3469916 -- and as per that following sap note 1682686 resolves this specific issue but, in our case it does not !
In short : as of now we are at dead end  !!
Pl. share your knowledge, inputs - Thanks.
Thanks,

Hi Amit,
Thanks for the suggestion - telnet to CMS Host is successful.
I see the following entries in /tmp - file :
=======================================================================
//verify dataservices installation begin
CMS_CONNECTED=true
CMSVersion=14.1.0
BuildNumber=1278
DS_INSTALLED=false
//Local server hostname is : ITSBEBEL00<local_ds_host>.XYZ.COM
//SI_SERVER_NAME for EnterpriseNode is : <cms_host>.XYZ.COM
NODE_LIST=
IS_ADMIN=true
The service DS.AdminService could not be found on the client side (FWM 02027)

com.businessobjects.di.install.CMSConnect.main(CMSConnect.java:321)
DS_AdminService_Installed=false
RETURN_CODE=2
//verify dataservices installation end
====================================================================
It is puzzling that without the completion of Data Services Installation why the DS Installer is expecting ' DS.Admin services " running on 'client' ...this is an extension or add on of Data Services (to be installed on separated linux host) and communication is supposed to be from DS Host to CMS Host !! Where is the scope of client here ??
We do see that connection to CMS Host is possible ..I found few more notes related to this ( not for the identical OS+DB+DS ver. i.e. Linux+Oracle+DS 4.2 SP2)  e.g. 1824068, 1632561 but, none of it helps to resolve the issue.
Thanks,
