Networking
Most of the information you need to properly configure networking is included in Configuration->Base System->Network Settings.
The initial network configuration is done during the installation wizard upon the first install. See the Installation Guide for more information on this process.
We have been made aware of a problem after a hardware crash on hypervisor (VMWare, Hyper-v, KVM) restart where all the network parameters are unset.
This seems to be caused by the MAC address of MailCleaner being changed and so the network is not necessarily able to address the expected MAC address when it comes back up with the same settings.
Udev store network informations in files (/etc/udev/rules.d/). One of them are the persistemt rules which match network interface and IP with MAC address.
If this happens, you should be able to remove the old MAC address assignment by :
- logging in on the MailCleaner console as root
- editting udev file : /etc/udev/rules.d/70-persistent-net.rules
- removing the line containing the NAME="eth0" string
- restarting the MailCleaner
