Hi there guys!
I have a small task that I have to accomplish, but I don't seem to be able to do that.
I have a server that I don't have physical access to, and I mostly control it with webmin. The server is running 2 websites. Both of these websites have their own domains that are linked to... (1 Reply)
if i have the command ifconfig eth0, what will the output be and how can i use either awk or grep to isolate and display the IP address, subnet mask and physical address of my host (1 Reply)
I saw an example on the web, it is an HP-UX command:
ifconfig lan0 unplumb
ifconfig lan0 plumb
so what is plumb actually, I check HP-UX man page and still no idea.
What is the difference if I do in this way?
ifconfig lan0 down
ifconfig lan0 up
:confused: (1 Reply)
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)
Hi,
Just installed Centos 5.1 on HP DL360, on this system I have to close to ten nic's. How can I find which one is eth0? When I do " ifconfig -a" I see all of them, but I can't tell which is eth0?
Please advice. (2 Replies)
Hi,
I have just installed RHEL 5.4 on a BL430c-class server and I am attempting to connect to the network only when I try and start eth0, I get the following error?

Hello,
I re-installed my laptop and installed a new copy of VMBOX, I created a VM Machine with my Rhel5 and a CEntos copy as well.
I am using a laptop HP DV4, I use wireless on the laptop.
Usually when I boot up in to either machine I would get eht0 and lo as usual now I just don't get... (4 Replies)
Hi,
I have noticed some performance issues on my RHEL5 server but the memory and CPU utilization on the box is fine.
I have a 1G full duplexed eth0 card and I am suspicious that this may be causing the problem. My eth0 settings are as follows:
Settings for eth0:
Supported ports: ... (12 Replies)
Hi all,
I am running a CentOS 6.4 box as an IDS and I need to configure one interface as the management interface which will require a firewall. However other ports (in promisc mode without IP) will have to be configured such that IPtables allows all traffic.
I need to achieve this by editing... (4 Replies)
Hi guys,
I really need your help with this.
My network interface eth0 is up but not running. I checked udev rules and ifcfg-eth0 files to make sure the mac address are the same.
It just would not come up. Please please I will really appreciate the help here.
Thank you in advance. (3 Replies)

IFSCHEME(8) Commands IFSCHEME(8)NAME
ifscheme - scheme control for network interfaces
SYNOPSIS
ifscheme [-v] [[-s] newscheme]
mapping <interface> script ifscheme-mapping
DESCRIPTION
ifscheme allows you to change network configuraton schemes or query the current scheme. It integrates with the ifup(8) command and inter-
faces(5). For example, you might use this program to configure a "home" scheme and a "work" scheme for a network device on a laptop. When
you move between home and work, a simple command can reconfigure your networking.
If you run the program with no parameters, it will tell what the current network scheme is.
The ifscheme-mapping utility is used to tell the ifup and ifdown utilities about the current scheme.
OPTIONS -v
--verbose
Run in verbose mode. This is passed in to the ifup and ifdown programs as well.
-l
--list list all schemes available/defined in /etc/network/interfaces.
newscheme
-s newscheme
--scheme newscheme
Change to a new network configuration scheme. When the scheme is changed, network interfaces that were using the old scheme will be
taken down and brought back up to use the new configuration scheme. -s or --scheme are mandatory if newscheme begins with a -.
CONFIGURATION
To make the program do anything useful when a scheme is selected, you must edit /etc/network/interfaces to add a mapping for the interface
(or interfaces) that can be controlled on a per-scheme basis. Suppose you want to control eth0 in this way. You might have an existing eth0
configuraton in there, such as:
auto eth0
iface eth0 inet static
address 192.168.1.5
netmask 255.255.255.0
gateway 192.168.1.1
To change this so you can chose between static routing and dhcp, replace it with the following (it helps to ifdown the interface first).
auto eth0
mapping eth0
script ifscheme-mapping
iface eth0-home inet static
address 192.168.1.5
netmask 255.255.255.0
gateway 192.168.1.1
iface eth0-work inet dhcp
Now if you run "ifscheme home" and ifup the interface, you'll get the eth0-home configuration stanza. If you run "ifscheme work", it will
be changed to the eth0-work stanza. You can add additional stanzas as desired, but the label must always be of the form <hardware inter-
face>-<scheme name>.
If you have a second interface (perhaps a wireless network card on eth1), you can duplicate the above for that interface, changing the eth0
and the configuration details as appropriate, but remember to add an iface stanza for every scheme name for the second interface.
FILES
/etc/network/interfaces
the interfaces definition file
/etc/network/run/scheme
the current scheme
/etc/network/run/ifstate
a record of the current state of the interfaces, managed by ifup and ifdown
BUGS
All schemed interfaces will have the same scheme.
Any schemed interface which does not have an entry for the current scheme and is not configured when the scheme is changed will not be suc-
cessfully configured when it is brought up.
