How to generate encrypted passwords in the Nagios server?
Procedure: Step 1: Run the following command and verify that the OpenSSL function exists on the Nagios server: # rpm -qa | grep openssl The following information indicates that the OpenSSL function, which meets the encryption requirements, exists on the Nagios server: openssl-devel-0.9.8a-18.15 openssl-0.9.8a-18.15 compat-openssl097g-0.9.7g-13.5 Step 2: Run the following command to encrypt a device password, read and write community or trap community name: # cd /usr/local/nagios/bin/huawei_server # python genKey.py encryptPwd Information similar to the following displays the generated password cipher text: I2FsdGVkX19RU+Tr4ZoLg4Ji2Rpx4ZGAOeOsqLlxKpI= NOTE: The current key is encrypted by the default cipher key of the system. To manually generate a new key, run the following command and then go to Step 2: # cd /usr/local/nagios/bin/huawei_server # python keyhandler.py setkey If information similar to the following is displayed in the command output, the key is successfully generated and is automatically saved to the configuration file(configInfo.cfg): 45FsdGVk419RU_2344ZoLg4Ji2Rpx4ZGAOeOsqLlx34= Step 3: Record the cipher text for the device password, read and write community or trap community name.
