1. eth0 is set to automatic obtain IP from provider (DHCP)
2. wifi0 is set to static IP (local) 192.168.1.1
My ifcfg-wifi0 is configure in /etc/sysconfig/network-scripts/ifcfg-wifi0 as below
# Atheros Communications, Inc. AR5212 802.11abg NIC
DEVICE=wifi0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.1
NETMASK=255.255.255.0
HWADDR=00:17:9A:75:48:37
my /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=pc1.homeserver.in
eth0 IP is connected to broadBand internet service provider device WiMax and IP change time to time from internet service provider. How can I get IP for gateway in /etc/sysconfig/network. I am using Redhat enterprise Linux 4.
in my iptables script I define the environment like this:
Code:
# ENVIRONMENT
# Private interface
IF_PRV=eth1

if I give the IF_PUB interface the DYNAMIC IPaddress assigned by my ISP how can I define it in IP_PUB and also the NET_PUB so I can then use it for the firewall rules.
exemple rule:
Quote:
iptables -t nat -A POSTROUTING -s $NET_PRV -o $IF_PUB -j SNAT --to $IP_PUB

I need define a user /password for sasl but want the authentication at runtime be automatic - no explicit prompting the user while accessing a tcp socket with some applications that need the authentication (e.g libvirt)
so I try : saslpasswd2 -c -p -a libvirt <user>
and it hangs (if i now press Enter it says : "invalid parameter supplied") . if I avoid the -p flag the above commad works fine and prompts for password and later when using the tcp it prompts for the above defined user/password and autheticates ok .
But I want without the explicit authentication
The man pages says -p Pipe mode - saslpasswd2 will neither prompt for the password nor verify that it was entered correctly. This is the default when standard input is not a terminal.
In the past (before some upgrading of libvirt via rpm) I had the SASL authentication at runtime done automatically with no explicit prompting the user

Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.
My files are as follows:
I'm running Ubuntu 10.10 and I'm having problems trying to assign it a static IP address. No matter what I put in the Preferences->Networking area (identifying the interface as Manual)... it still will query DHCP for an address if I run the dhclient command. I'm using to using ubuntu server where I just set the IP in the interfaces config file.
View 1 Replies View RelatedI am running my own Postfix mail server. Some time ago I noticed that most email was rejected because of the server's dynamic IP address. So I got a fixed IP address. However then I noticed that some mails got rejected due to failing the reverse DNS check. So my ISP told me to get a range of IP addresses and they could then create a PTR record for one of those addresses. That is now running but it turns out that the IP address used for the PTR record is a ... dynamic IP address. So Spamhaus PBL rejects my emails again.

I have a few external IP's assigned to me by my ISP. I have IPcop as my router/firewall. I am wondering how to bind 1 of my external ip's to my internal ip address. So I do not have to port forward, etc. For Example, 77.77.77.77 to 192.168.1.123 and on the server it see's the external IP address.
View 2 Replies View RelatedSome people may need to change the mac address of their ethernet network cards. This can be easily done with fedora with command line. Just follow the steps below:
1. Log as root on a textual console (ctrl+F2) or through "su -" command in your console
2. Print your network configuration with ifconfig
[root@localhost ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:23:8B:6A:7E:9E
inet addr:10.1.128.244 Bcast:10.1.255.255 Mask:255.255.0.0
inet6 addr: fe80::218:8bff:fedb:7e9e/64 Scope:Link
[code].....
Here, eth0 is the ethernet interface of your system. The mac address is put in red.
3. Change your mac address using the following syntax
ifconfig eth0 hw ether 00:18:8BA:7E:90
The new value (in green) must be hexadecimal
4. if you have a dhcp server that distributes the adresses automatically, then request a new adress for your eth0 interface
[root@localhost ~]# dhclient eth0
5. Now, your interface is up and have a new mac and IP addresses. This feature may be useful if the network administrator ban you according to the mac adress, for example .........

I downloaded Fedora 10 32bit and put it on a Dell Dimension 8200 to save it from the recycle bin. Everything seems to work except I cannot get an IP addr. Roadrunner is my ISP using a cable modem and a Linksys Instant Broadband Series Etherfast Cable/DSL router model BEFSR41. In system-config-network, the nic shows inactive. If I activate it a window opens saying "determining IP information for eth0". After a short time the message adds the word "failed". Using a Windows PC on the same network, I can look at the DHCP connections on the Linksys and I see the MAC addr for the PC running Fedora.
From the OS installation, /etc/sysconfig/networking/devices/ifcfg-eth0 has following:
DEVICE=eth0
HWADDR=00:80:ad:d1:88:c9
ONBOOT=yes
[Code]....
I have specified Primary DNS address in Network Manager's DNS tab and saved those settings. But when I restart my PC, Primary DNS address will go blank. How can I save this address premanently?
View 6 Replies View RelatedWhat I am trying to do is the following: I have many IBM MT-M 6223 towers (Intel Xeon processor) that need to run a certain Fedora 9 configuration. It is working on one box, now it needs to be replicated on all of the others. What is being done is the working box is cloned, and then that image is loaded on all of the others.These boxes have 5 total Ethernet devices. There is one on-board port, and there are two 2-port expansion cards for a total of 5.
There was one initial problem out of the gate that has since been solved (or perhaps not completely). What was happening is that the boxes that received the cloned image had their Ethernet devices misnumbered. Instead of eth0 through eth4, they were numbered eth5 through eth9.This was eventually traced to the following file: /etc/udev/rules.d/70-persistent-net-config. That file contained the original settings from the box that was first cloned. It had eth0 through eth4 at the top with MAC addresses belonging the box that was the source of the cloned image. It looks like this mismatch was detected, and five more entries, numbered eth5 through eth9, got appended to the bottom with MAC addresses belonging to the new box.
Once /etc/udev/rules.d/70-persistent-net-config was deleted, and the machine rebooted, the 5 ethernet devices came up with the correct numbering (0 thru 4). /etc/udev/rules.d/70-persistent-net-config was rebuilt with the correct devname-MAC pairing.
Now for this new problem.... Part of the configuration across all these machines is that only eth3 should have an IP address. It is a static IP address set through the /etc/sysconfig/network-scripts/ifcfg-eth3 file. All of the other devices must NOT have any IP address. They are either not used or used only for raw Ethernet.After clearing out /etc/udev/rules.d/70-persistent-net-config, /etc/sysconfig/network-scripts/ifcfg-eth3 was edited to give the new box its own unique static IP address before rebooting.Sample ifcfg-eth3 file:
Code:
DEVICE=eth3
BOOTPROTO=static

How to set the ip address to particular device(ethernet device)
View 4 Replies View RelatedI've just reinstalled F14 with KDE rather than Gnome and I'm finding that I'm unable to assign a static IP address to my wired connection.
KDE automatically connects via DHCP, but when I go into KDE's network manager, the eth0 connection isn't listed. In fact, no wired connection is listed. If I manually add one with the correct settings (including a static IP), it switches back to DHCP upon rebooting.
How can I get around this? Should I install the networkmanager-gnome package?
