How do I configure an AppManager for UNIX agent to use encryption?
Error: 'I/O Error with socket stream.'

AppManager UNIX agents grey-out over an encrypted connection.

To generate a new key and enable it on the UNIX agent:

1. Generate a new key on the management server(s):
   • C:\Documents and Settings\Administrator>nqkeygenunix -db qdb:sa:lodestone -new
     Please enter the SQL password: ******
     Database connection successful
     Current Unix Agent security level is = 0;
     0=none; 1=encrypt; 2=MS auth;
     This command is going to overwrite the existing key
     and install a new key.  Are you sure(y/n) ? y
     Please enter the key password: ******
     Saving into QDB successful.
     Operation succeeded.
2. Check the key out from the QDB and into a file on the MS:
   • C:\Documents and Settings\Administrator>nqkeygenunix -db qdb:sa:lodestone -skey AMUNIXKey
     Please enter the SQL password: ******
     Database connection successful
     Current Unix Agent security level is = 0;
     0=none; 1=encrypt; 2=MS auth;
     Extraction from QDB successful.
     Operation succeeded.
     Saving server key file successful.
     Operation succeeded.
3. Copy the file AMUNIXKey to your UNIX agent under AMUNIXAGENTPATH/conf/
4. In a text editor, edit the XML file AMUNIXAGENTPATH/conf/nqmcfg.xml
5. Insert or update this line (with the appropriate path and file name) immediately before the end of a configuration section, signified by </CONFIGURATION>:
   • <KEY_STORE_FILE>AMUNIXAGENTPATH/conf/AMUNIXKey</KEY_STORE_FILE>
6. Save the file.
7. Cold start the UNIX agent.

The key is invalid for the current time and date.
