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?
