Working with SSL Server Certificates

Installing SSL Server Certificate on fresh NGS

Below steps describe how to install an SSL Server Certificate on a fresh NGS. This tutorial cannot be used to replace an SSL Server Certificate.

Copy both the .crt and .key file to the home folder of user root.

Verify the certificate file only contains the server certificate. A certificate bundle can't be used.

# vi server_certificate_file.crt

Only one certificate section should be visible.

Stop the nGeniusONE server process.

# pmbin
# ./stop

Step into the tools folder.

# cd ../tools
# ./nscertutil.sh

Now choose option 2 and follow the steps. You can use the server's hostname (without suffix) as alias.

Start the nGeniusONE server process.

# pmbin
# ./start

As a final step remove the certificate file and key file from the system.

# rm server_certificate_file.crt
# rm server_certificate_file.key

Replacing SSL Server Certificate on NGS

Below steps describe how to replace an SSL Server Certificate on NGS. This procedure applies to a certificate that is still valid. If the certificate has expired, this procedure can't be used.

Copy both the .crt and .key file to the home folder of user root.

Verify the certificate file only contains the server certificate. A certificate bundle can't be used.

# vi server_certificate_file.crt

Only one certificate section should be visible.

Verify the content of the certificate store.

# /opt/NetScout/jre64/bin/keytool -list -v -keystore /opt/NetScout/rtm/html/ngeniusclient.truststore

Record the alias of the certificate that needs to be replaced.

Now, remove the certificate using the alias.

# /opt/NetScout/jre64/bin/keytool -delete -alias <alias> -keystore /opt/NetScout/rtm/html/ngeniusclient.truststore
