I have searched through much material but have not found a straightforward answer to my two NIC question.

We have a small office network comprising ten laptops (all running WinXP) and a server (running Ubuntu 9.10). BackupPC is installed on the server and operates well except the following.

Connections to the clients are by SMB. Each client has both a wired Ethernet connection and a Wi-Fi connection. Either one or both connections can be active at any particular time depending on where the laptop is physically located and what the user is doing. On each laptop each connection has a unique IP (assigned by DHCP, but exactly the same IP is assigned each time).

Consequently, there are three ways one might reach a particular client: when only the Ethernet IP is active, when only the Wi-Fi IP is active or when both IP’s. Ideally at scheduled times BackupPC would connect to each client by wire or Wi-Fi (or even both if that made any sense) depending on the way the laptop is connected to the network at the time the backup is initiated.

The hosts file is as follows (this is just a fragment for laptops 11, 12 and 13)):

# Following have both wired and wi-fi connnections

# The Aliases are current as of 2010-10-10

# IP Address           NetBIOS         Aliases

#                      Name

#192.168.1.111         SSSS11         Sam-Wired

192.168.1.211          SSSS11         Sam-Wi-Fi

192.168.1.112          SSSS12         Peter-Wired

#192.168.1.212         SSSS12         Peter-Wi-Fi

192.168.1.113          SSSS13         Ned-Wired

#192.168.1.213         SSSS13         Ned-Wi-Fi

BackupPC works with each of these clients when only one connection (wired or Wi-Fi) is active. Note that both Wi-Fi (SSSS11) and wired (SSSS12) connections work well.

BackupPC cannot find the client when both connections (wired and Wi-Fi) are active.

My question: How can BackupPC be configured to enable it to connect to a client by either wired or wireless connections?
