Environment
- EDR Server: 7.7.1 and above
- Email
Symptoms
The server URL being sent in the alert emails is incorrect
Cause
In 7.7.1 and above, code was added to check for available network interface cards and utilize the correct one to pull the IP and get the hostname.
- DNS server is returning the incorrect FQDN
- /etc/hosts first <ip> <servername> entry is incorrect.
Resolution
- Confirm your DNS server listed in /etc/resolv.conf are returning the correct FQDN based on the IP
- If this is returning an internal FQDN that is not accessible outside or need to work around what is being returned, update the /etc/hosts entry (127.0.0.1 will not work)
myip my_fqdn_servername
example, notice the use of the actual IP and not just the loopback in the first line. :
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 myservername
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.222.128 myservername
Additional Notes
- HEDR customers have been corrected as of 9/28/22
