multiple IPs via PPP to ISP

multiple IPs via PPP to ISP

Post by David M. Fens » Fri, 27 Feb 1998 04:00:00



Can this be done?  

Setup up multiple IP addresses multiple domains on SCO 5.0.4 system where
the connection to the ISP is a dedicated PPP (dial up) connection.

I know this works fine over a network connection, but am unsure about using
a PPP link.

Thanks.

It depends on how you have PPP set up. If you're using the PPP adapter
as a default route, then you can just add domains to the ethernet. If
you don't have an ethernet connection at all, you might be able to
add them to the loopback. Or put a 10base2 NIC in and stick a T on it
with 2 resistors, and use that.

The latter way does work; I did it once (5.0.2 Fast Start)

1. ipconfig - multiple IPs - swapping IP effect on alias IPs?

Hello,

my IP structure looks like this:
# ifconfig -a
 lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
         inet 127.0.0.1 netmask ff000000
 hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
         inet 194.163.186.149 netmask fffffff0 broadcast 194.163.186.159
         ether 0:80:17:28:ae:8f
 hme0:2: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
         inet 194.163.186.158 netmask fffffff0 broadcast 194.163.186.255
 hme0:5: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
         inet 192.168.183.156 netmask ffffff00 broadcast 192.168.183.255

I enable and disable the various alias IPs using plumb and unplumb.
/usr/sbin/ifconfig hme0:1 plumb
/usr/sbin/ifconfig hme0:1 194.163.186.156 broadcast 194.163.186.255 netmask
 255.255.255.240 up

Can I also do a plumb and unplumb with hme:0, the hardware IP of the machine?
I unfortunately do not have a test-machine here. Would hme0:2 and hme0:5
get changed or stay as they are without being influenced?

Thanks,
    Armin
