问题
I have added eth0:1 with one more ip to the interface file of my debian box. The thing is now i want my ftp client which is lftp to connect using the new ip address. What was the directive to use a specific interface to communicate? Thanks

In lftp set the net:socket-bind-ipv4 option to the local IP address that you want the client to use:
set net:socket-bind-ipv4 a.b.c.d
You can type that directly into the client but if you're going to do this regularly then it would make more sense to add it into your $HOME/.lftprc or $HOME/.lftp/rc file.
If you're using IPv6 then there's also a net:socket-bind-ipv6 option.
