when i finish installed rhel 4.4 to my hp dl585 box, ifcfg-eth0 and ifcfg-eth1 is not available.when i ifconfig -a,i can not see the eth0 and eth1, only lo0 and si0. Unlike to the other server i found eth0 and eth1 files in
/etc/sysconfig/network-scripts/.
what will i do? (2 Replies)
I have been looking in the scripts for interface management, in an effort to kick off a script of my own on any "significant network event" (I will qualify that in a bit)
I managed to add a check to tell netplugd to run my script every time there is a hot-plug event. Now I need to make it so my... (0 Replies)
I have a little script in the /etc/network/if-up.d (debian). It should do something and write the output to a log file. But it doesn't seem to work.
ifup wlan0 dosomething >> /var/log/dosomething.log
I would like to add the date to the output, can somebody help me please?
Thanks! (6 Replies)
Hi Guys,
is there a way to send traffic coming from the source iface (eth0, eth1)? i need to test traffic that will come from both eth0 and eth1 from a Linux box.
Thanks,

Hi Guys,
I am working as a L-1 support and i want to know that are the precaution need to take on eth0(Ethernet card) i heard on production server it is very much important, what are the steps need to observe on this tickets. (1 Reply)
hi there
the ethernet wire was out of the pc when the system started.
#ifconfig
#ifconfig -a
i did not get any ip for eth0.
i plug the cable into the pc
#ifdown eth0
#ifup eth0
now the ip address is assigned to eth0
Question is : IS this right way to bring ethernet down... (2 Replies)
hello,
first of all i am new to unix so maybe my problem is very easy for many of you but is very important to me.
So the idea is that i want to use a ubuntu 10.4 machine as a router from eth0 to eth1.
but the traffic routing is nor working properly
i configured the 2 interfaces to be... (2 Replies)

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.
