Some of our customers use eSafe as forwarding proxy for SMTP and HTTP scanning. Today I had to restore an eSafe, which is configured in NitroInspection II Router mode. I had created a backup configuration file from the running eSafe server and installed a new eSafe server with the default settings.

After the installation I connected my laptop to the eSafe server and opened the default browser page:

https://<IP Addr>:37233

After logging in with the default username (admin) and password (esafe), I browsed to the backup configuration file and started restoring to this configuration. The eSafe appliance needs to reboot after the restore.

I know noticed that after the initial restore and reboot, the eSafe server lost the IP configuration from both NIC’s in the server. I had to restore the IP settings manually, which can be done by editing the following files:

1. /etc/sysconfig/network-scripts/ifcfg-eth0
2. /etc/sysconfig/network-scripts/ifcfg-eth1

I always forget the syntax when editing the networking files, so I had to search the internet for the correct syntax. Below the configuration of eth0.

DEVICE=eth0
IPADDR=192.168.3.2
NETMASK=255.255.255.0
NETWORK=192.168.3.0
BROADCAST=255.255.255.0
GATEWAY=192.168.3.1
ONBOOT=yes

After rebooting the network service (/etc/init.d/network restart) I was able to communicate with the eSafe server and everything looked normal, but it wasn’t. I noticed that the service eSafe wasn’t able to start.

Contacting eSafe resulted in re-installing the eSafe appliance from scratch. Manually configure the correct IP settings through the web interface and only restore the file /opt/eSafe/eSafeCR/esafecfg.ini. Next I rebooted the server and this time the configuration was restored and the service was running.

eSafes technical personnel told me that the problem could arise, when restoring the tar.gz file to different hardware, and that’s exactly what I tried.
