Adding an alias to an ethernet interface using ifconfig

To add an address to an ethernet interface :

ifconfig ethx:n [ipaddress]

where :
x = ethernet number
n = alias number

example

ifconfig eth0:1 10.0.0.10
will add 10.0.0.10 to eth0 in addition to the existing ip address [eth0]

To monitor ALL the incoming and outgoing mail that goes thru the system :


config setprop qpsmtpd Bcc enabled BccUser signal-event email-update


All the email will be automatically BCCed to .

To turn off this Bcc feature :
onfig delprop qpsmtpd Bcc enabled BccUser signal-event email-update

It won't delete user, it'll just disable the Bcc function.
