Applies ToRSA Product Set : SecurID
RSA Product/Service Type : RSA Authentication Manager
RSA Version/Condition: 8.1 Service Pack 1
Platform : SUSE Enterprise Linux
O/S Version : 11 Service Pack 3
Product Description : SecurID Appliance
IssueWhen connecting to the Operating System of the SecurID Appliance running RSA Authentication Manager 8.1 software an error message is seen "Server unexpectedly closed network connection".
Example; taken when using PuTTY as the SSH client:
User-added image
TasksDebug can be enabled allowing for an administrator to investigate why this error could be occurring.
  1. Logon to the local console as rsaadmin
  2. Use an editor to make a change to the sshd configuration file (e.g. vi /etc/ssh/sshd_config) and change the LogLevel from INFO to VERBOSE (or DEBUG for more information) and save the change
  3. Restart the sshd using the command: sudo service sshd restart
  4. Log data for sshd is written to the /var/log/messages log file
NOTE: values that can be used for LogLevel: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2 and DEBUG3
ResolutionEnabling the SSH debug would be one step in investigating why the server unexpectedly closed the network connection between the server and the SSH client.
Please note that the error message usually occurs due to a network timeout or interruption so please perform other network related checks between the SSH client and authentication manager instance. 
NotesPuTTY is a free implementation of SSH and Telnet for Windows and Unix platforms, along with an xterm terminal emulator. Refer to URL http://www.chiark.greenend.org.uk/~sgtatham/putty/ for information on PuTTY.
