This section provides information to enhance your experience with Server Administrator implementations and environments.

• To perform an Express Install on the Red Hat Enterprise Linux Server operating systems, run srvadmin-install.sh -x from the SYSMGMT/srvadmin/linux/supportscripts directory.
• Port 1311 is the default port for Server Administrator. It is a registered port number of Server Administrator. If another application is configured to run on port 1311 before Server Administrator is installed, the DSM SA Connection Service does not start after installation. Before you install Server Administrator, ensure that the port 1311 is not in use.

• If you run a security scanner tool such as Nessus and the Server Administrator web server, security warnings may be displayed against port 1311. It is the port running the Server Administrator. The engineering investigates the warnings and is determined to be false positives (invalid security warnings) that you can ignore. The following are the warnings:
  • The web server on 1311 allows scripts to read the sensitive configuration or XML files.
  • The web server on 1311 allows you to delete /. It implies that the web server allows a remote user to delete the files in root on the server.
  • The web server on 1311 may be susceptible to a 'www Infinite Request' attack.
• It is possible to make the remote thttpd server perform arbitrary code by sending a request like: GET If-Modified-Since:AAA[...]AAAA . Solution: If you are using thttpd, upgrade to version 2.0. Otherwise, contact the vendor for a patch or change the web server. The CVE on it is CAN-2000-0359.
• Enabling Integrated Windows Authentication in Internet Explorer is not required to activate the Single Sign-On feature.
• The Server Administrator security settings are not applicable for Active Directory users. Active Directory users with read-only login can access Server Administrator, even if the access is blocked in the Server Administrator Preferences page.
• Dell SNMP MIB files allow you to obtain and verify information. The supported software agents provide the information. PowerEdge software agents support the current MIB files at \support\mib on the Systems Management Tools and Documentation DVD.
  NOTE:A MIB-II-compliant, SNMP-supported network management station is required to compile and browse MIB files.
• OpenManage support for Encrypting File System (EFS): To improve security, Microsoft allows encrypting files using EFS.
  NOTE: The Server Administrator does not function when its dependent files are encrypted.
• If you have to uninstall and reinstall the operating system SNMP service, then reinstall Server Administrator. So that the Server Administrator SNMP agents are registered with the operating system SNMP agent.
• Server Administrator UI and CLI Response Time: On PowerEdge 13G or later servers, the response time for some components of the Server Administrator UI and CLI are increased to several seconds. It is because the Server Administrator does not cache some of the DRAC or iDRAC data. The data is retrieved from the DRAC/iDRAC when you request for it. Following are the Server Administrator UI pages for which the response time may have increased:
  • On the Server Administrator home page, log in to Remote Access > Users > Alert Management > Platform Events.
  Following are the Server Administrator CLI commands for which the response time may have increased:

  omreport chassis remoteaccess config=user

  omreport system platformevents

   omreport system pedestinations

  The time variation depends on the hardware and operating system.
• iDRAC also has its own CLI that is accessed through the racadm command. You can add racadm commands to a batch or script file to automate various user tasks. To limit the stress load on the managed system and RAC, add sleep or delay commands of one or two s between the individual racadm commands.
• Server Administrator Device Drivers for Linux: Server Administrator includes two device drivers for Linux, Systems - Management Base Driver (dcdbas) and BIOS Update Driver (dell_rbu). Server Administrator uses these drivers to perform the systems management functions. Depending on the system, the application loads one or both of these drivers. These drivers are released as open source under the GNU General Public License v2.0. They are available in Linux kernels from kernel.org starting with kernel 2.6.14.
