Issue/Introduction

Before applying SO15969 CONTROL CENTER ACCESS DENIED (XCOMM1613E) WITH SECURITY=NONE and SO14571 ABEND S0C4 AT XCOMHTTP+7CE DURING PORT SCANS attacks by Qualys servers would interfere with transfers and STC would need to be recycled.

After maintenance, attacks do not interfere with transfers, but now the attacks are getting message about Command Center rejections: This is occurring on all LPAR's where the Command Center has been implemented.

            XCOMM0805I TCP/IP CONNECTION ENDED WITH IP=10.162.16.39              
HTTP        XCOMM1610I Control Center Connection Rejected    - GET / HTTP/1.0    
         XCOMM0780E Txpi  228: Select exception condition for socket 0      
          XCOMM0780E Txpi  215: Socket send error return value = 140          
          XCOMM0805I TCP/IP CONNECTION ENDED WITH IP=10.162.16.39            
HTTP       XCOMM1610I Control Center Connection Rejected    - GET /console/login
          XCOMM1610I Control Center Connection Established                    
          XCOMM1611I User nnnnn  authorized to use the Control Center      
          XCOMM1610I Control Center Connection Established                    

Since there are different servers attacking each day, there is no way to prevent this via Internet Protocol Security IPsec.

Is there a way to officially logoff the Command Center, because when entering the URL it reconnected me w/o  password verification.

 

 

Cause

XCOM may need a larger region size

Environment

Release : 12.0

Component : CA XCOM Data Transport for z/OS

Resolution

The XCOMM1610I messages are produced by the scan since the Control Center is started using the GET command form the browser.

Use the XCOM Storage Usage Worksheet to calculate/determine how much storage the XCOM task needs.

Yes, when you enter the URL it will connect you to the server without asking to reenter the password because it is saved in a cookie, if you have the cookie box checked on the top of the Settings tab.
