I have inherited a Motorola System V R32V3.2 system. The system works fine, but we need to change the network settings. I've changed the IP address successfully, however I'm lost on the gateway and subnet mask. I've changed the default gateway using
, but it changes back to 255.255.255.255 on reboot. I have not found anything on changing the subnet mask.
I've been looking for documentation on how to stop this behavior. I have two nics in my system.

eth1: configured w/ dhcp enabled connected to router

say i have a system on thats on a network with access to the internet.
now, i have sensitive information on this system and i do not want the system to be connected to the outside world anymore. how do i get it off the network without actually having to disconnect the cables?

Hello Unix Gurus Who I Hope Reads This,

Hi
i have created a solaris zone but have not yet connected any network cables for this new zone,

Hello, Newbie question on scripting - I'm looking to create a simple script that will work on RHEL5 that will adjust the network settings: ip address, default gateway, and subnet mask. If anything else needs to be done (service network stop / start) or should be done to make settings active - I... (4 Replies)
Hello, I just installed Fedora 16 and wanted to add some apps to startup but realized System settings has only a small setup of utilities and does not have option for adding apps to startup.

netmasks
netmasks(4) File Formats netmasks(4)NAME
netmasks - network mask database
SYNOPSIS
/etc/inet/netmasks
/etc/netmasks
DESCRIPTION
The netmasks file contains network masks used to implement IP subnetting. It supports both standard subnetting as specified in RFC-950 and
variable length subnetting as specified in RFC-1519. When using standard subnetting there should be a single line for each network that is
subnetted in this file with the network number, any number of SPACE or TAB characters, and the network mask to use on that network. Network
numbers and masks may be specified in the conventional IP `.' (dot) notation (like IP host addresses, but with zeroes for the host part).
For example,
128.32.0.0 255.255.255.0
can be used to specify that the Class B network 128.32.0.0 should have eight bits of subnet field and eight bits of host field, in addition
to the standard sixteen bits in the network field.
When using variable length subnetting, the format is identical. However, there should be a line for each subnet with the first field being
the subnet and the second field being the netmask that applies to that subnet. The users of the database, such as ifconfig(1M), perform a
lookup to find the longest possible matching mask. It is possible to combine the RFC-950 and RFC-1519 form of subnet masks in the net-
masks file. For example,
128.32.0.0 255.255.255.0
128.32.27.0 255.255.255.240
128.32.27.16 255.255.255.240
128.32.27.32 255.255.255.240
128.32.27.48 255.255.255.240
128.32.27.64 255.255.255.240
128.32.27.80 255.255.255.240
128.32.27.96 255.255.255.240
128.32.27.112 255.255.255.240
128.32.27.128 255.255.255.240
128.32.27.144 255.255.255.240
128.32.27.160 255.255.255.240
128.32.27.176 255.255.255.240
128.32.27.192 255.255.255.240
128.32.27.208 255.255.255.240
128.32.27.224 255.255.255.240
128.32.27.240 255.255.255.240
128.32.64.0 255.255.255.192
can be used to specify different netmasks in different parts of the 128.32.0.0 Class B network number. Addresses 128.32.27.0 through
128.32.27.255 have a subnet mask with 28 bits in the combined network and subnet fields (often referred to as the subnet field) and 4 bits
in the host field. Furthermore, addresses 128.32.64.0 through 128.32.64.63 have a 26 bits in the subnet field. Finally, all other
addresses in the range 128.32.0.0 through 128.32.255.255 have a 24 bit subnet field.
Invalid entries are ignored.
