My friend, Thats true, I did manually network configuration when server is rebooted. But I am right configuration like below. I don't know. All of the network files are right. What is the main problem!. I have one NIC.
Code:
bash-3.00# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1

Hi all
I am facing some problem with network card

Hello,
I need explanations about physical disks and physical volumes. What is the difference between these 2 things?
In fact, i am trying to understand what the AIX lspv2command does.
Thank you in advance. (2 Replies)
How do you test the physical network connection of an interface in solaris. I know that if you have an active connection and the cable gets yanked, you can look in the messages file to check for link failure messages. But is there any better way to see if you have good layer 2 connectivity? (1 Reply)
I was in smit, checking on disc space, etc. and it appears that one of our physical volumes that is part of a large volume group, has no free physical partitions. The server is running AIX 5.1. What would be the advisable step to take in this instance? (9 Replies)
Hello All,
Can anybody please tell me what is the maximum limit of Physical IBM Power Machine which can be handled by single HMC at a single point of time?

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.
