Networking :: Ip Address Keeps Getting Forgotten When No Device Attached?
Mar 24, 2011
I have a 2nd ethernet card in my system that I use to share my internet connection. eth0 is connected to the internet, and eth1 is used for my 2nd computer to connect into. Whenever the 2nd computer is turned off, eth1 forgets its ip address, then when then 2nd computer is turned on, it can't access the internet until I reset the ip address on eth1 ("ifconfig eth1 up 192.168.1.1). I only see this behavior under ubuntu 10.04, not the previous distro that ran on this box, slackware 12. How do I keep eth2 from forgetting the ip address when no computer is attached?

I am trying to setup a networked hP C6280 all in one device attached to my network via Cat5 cable. It has the IP 192.168.0.105 and I am experiencing problems with setting up HPLIP... I know I am not the only one to have this problem, but I cant find specific info for slackware and all the posts I've found on the web are outdated, often refering to slack 9 or having been posted prior to 2006....
I use Slackware -Current (prior to 13.1 release), CUPS V1.4.3 and HPLIP V3.10.2. When I try to setup my device in HPLIP (hp-setup), I select "network/ethernet/wireless device", then HPLIP discovers my printer @ 192.168.0.105 (like I expect), and then I click "add printer" and I get:
Code:
Printer queue setup failed. Please restart CUPS and try again. And then the setup exits. Of course restarting CUPS will not I reinstalled HPLIP and no luck. I can setup the device in CUPS, but if I proceed this way, I will not be able to select the attached scanner as a resource in XSANE.In other words, if I setup the all-in-one device with CUPS, it is considered only a simple printer..I remember that I had the same problem with Slackware 12.2 about 14 months ago, but cannot remember how I fixed it.

what would be the simplest way to find out device IP address? I don't know its factory set address, so my plan is to connect laptop directly to it with ethernet. it should respond to ping.

Currently my OS is Ubuntu 9.04 Jaunty Jackalope Desktop OS and my web server is Apache2. I have a public address 60.x.y.z and my pc local address is 10.x.y.z. I have a web app in my Apache2 which currently run in localhost(10.x.y.z).
I would like to enable the web app so that it could be browse from outside. I know there maybe some port forwarding process and some commands involved in order to do that. But I have no idea on the steps to do that.

Ubuntu was a good choice for free server O/S. I am currently downloading it. My ISP wants to bind my static IP to a MAC address of the device that will be making my connection for me. Should my server be behind my router or in front of it? I kinda wanted it to be the access point and be able to monitor the usage from all the terminals in my house. We have 4 other PC's, a laptop and a PS3. My server is a Acer Altos G530 with 3.2 Xeon Processor, 4 gb of ECC DDR,

I am trying to perform VM cloning using KVM in a centos 5.6 machines. I copy the memory contents of a running vm to an external state file and try to use that to start another VM in a different machine. While starting the cloned VM I provide a different mac address but once it resumes it has the old one . I tried changing the mac address in ifcfg-eth0 but I get the error: Device eth0 has a mac address xx:xx instead of configured xx:xx.Ignoring .
Is there some way to change the ip/mac of the cloned vm without the need to restart the VM ( Then the purpose of cloning will be defeated). Thanks a lot for the info.

I'm running ubuntu 10.04 and what I see is that after a few days up-time other computers on our LAN cannot resolve my ubuntu name anymore. This is critical since my NFS mounts stop working (my computer name is mentioned in the /etc/exports on the NFS server). My ubuntu is connected via DHCP.Is there some sort of refresh mechanism which needs to be configured in ubuntu?

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.

I 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.

We�re experimenting with deploying SUSE 10 SP3 systems and adding them to a Windows domain and DNS. Oddly, when we register in DNS, it gets registered under two address: the real IP address, and the address 127.0.0.2. Also, an ip addr command shows that the loopback device lo has two addresses: 127.0.0.1 and 127.0.0.2.
The above behavior is just on SP3. On SUSE 10 SP2, the lo device has only the 127.0.0.1 address, and the system is able to register correctly in DNS.
Do you know what the 127.0.0.2 address signifies, or how to get rid of it?

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.

I have got a Arch Linux laptop running KDE. I have recently purchased a Dlink DNS 323 network attached storage and have installed Debian Lenny on it. I have been connecting to it via ssh and have created a network folder on Dolphin for easy GUI access ( using ssh protocol). However I cannot seem to figure out how to download stuff directly to the network drives. In firefox, it does not allow me to browse to the Dlink when I try to specify the download path.

How can I find a MAC of hardware attached via ethernet cable? I have been working nicely with an industrial scanner that is controlled by a Linux PC via an ethernet cable, but the hard drive has died I need to get it working again. The problem is that the main PCB has a Realtek RTL8019AS ethernet controller chip: [URL] which I believe is used in the most basic way possible, applied straight off-the-shelf and unconfigured. To utilise the chip ARP commands are used to assign an IP address to the chips MAC address e.g. something like:
arp -s 192.168.2.5 00-05-a4-00-a8-f8
Unfortunately the actual MAC address was lost along with the HD Th only thing I could have a reasonable guess at is that the chip will have a default subnet of 255.255.0.0 or 255.255.255.0
