Re: [foxboro] IP MASKS

Your IP address 172.27.8.74 on the second Ethernet port indicates that your
AW is part of the Class B network (128-191) 172.27.0.0.
So the entry you need to add to the /etc/netmasks file shoud be:
172.27.0.0      255.255.254.0

This should not impact your Nodebus settings since these are on a different
Class B network (151.128.0.0).

Hi Alex,

This netmasks file affect the I/A addressing?
In my case I need use 255.255.254.0 as our mask, with the 172.27.8.74 IP =
address, what I need to configure?

Best regards and thanks for your help.

Cordial saludo,

Asunto: Re: [foxboro] IP MASKS

The particularity of Solaris 2.5.1 is that netmasks can only be defined =
for a network number that is a class A, B or C network number.
For example, you cannot define a netmask for the 10.19.123.0 network =
(class
A) but you can define a netmask for the 10.0.0.0 network.
So some limited masking can be exercised but with care...
AW5101# more /etc/netmasks
#
# The netmasks file associates Internet Protocol (IP) address # masks with
IP network numbers.
#
#       network-number  netmask
#
# The term network-number refers to a number obtained from the Internet
Network # Information Center.  Currently this number is restricted to being
a = class # A, B, or C network number.  In the future we should be able to
support # arbitrary network numbers per the Classless Internet Domain
Routing # guidelines.
#
# Both the network-number and the netmasks are specified in # "decimal dot"
notation, e.g:
#
#               128.32.0.0 255.255.255.0
#
# AD 2006/05/05
10.0.0.0 255.255.255.0
AW5101# ifconfig -a
lo0: flags=3D849<UP,LOOPBACK,RUNNING,MULTICAST> mtu 8232
        inet 127.0.0.1 netmask ff000000
le0: flags=3D863<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICAST> mtu 1500
        inet 151.128.8.65 netmask ffff0000 broadcast 151.128.255.255
        ether 8:0:20:76:77:3b
le1: flags=3D863<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICAST> mtu 1500
        inet 10.19.123.199 netmask ffffff00 broadcast 10.19.123.255 =
<------
This mask is the result of the entry in /etc/netmasks !
        ether 8:0:20:76:77:3b
