APPENDIX A: UPLOADING SSL SECURITY CERTIFICATES
See below for troubleshooting instructions in case the unit's WebUI no longer loads.
A.1.8 HOW TO TROUBLESHOOT A FAILED WEB UI ON THE SEC5
NOTE: These steps are only for troubleshooting a bad SSL certificate file, which prevents the unit's Web UI from
appearing because the Apache service cannot start.
The SSL certificate which you can upload from the Web UI will be stored as this file:
/flash1/user/init.d/userkey.pem
If this file doesn't exist, then the unit's built-in certificate will be used. If the uploaded certificate is a broken file,
remove it and restart Apache to get a working Web UI.
1. Log in to the unit's SSH console as the root user. (The password is whatever the SNMP write community is named.)
You then have two options:
a) Remove the corrupt .pem file, which will cause the default certificate to be used by using the following command:
rm /flash1/user/init.d/userkey.pem
b) Overwrite the corrupt .pem file with a file that you know is good by using the following command:
cat >/flash1/user/init.d/userkey.pem
and then copy the certificate contents, press <Enter> and then press <Ctrl> <D>.
2. After removing or overwriting the certificate, restart Apache by using the following command:
/etc/rc.d/init.d/apache restart
3. Try to log in to the Web UI again.
