My test box is running 9.10 desktop,bind,dhcp,LAMP. Everything is working good, except for one thing. How do I configure the DNS to answer the IP of eth3 (192.168.0.2), no matter what the client asked for? If you ask my DNS for google.com, I want it to return 192.168.0.2. I know this can't be that hard, I just can''t figure it out.
View 4 RepliesHow can I set the outgoing port for the socket? In wireshark, my outgoing port is 1024, and i want to set it to 6800 (or a similar port) I see the outgoing broadcast-message in wireshark, but no answer. There are three ECU's in the LAN, which should answer. The following code is a mixture of C/C++ and jointed from different articles:
[code]...
In wireshark I can only see the outgoing message. But the "recvBuffer" (in the lower part of the code) contains the same content as the sendBuffer. Is it right, that I need a sender and further more a receiver? Or should I receive the broadcast-answer on the same socket on which I send the bc?
I have managed to get everything MOST of the way setup...Come to find out though that I cant get conky to function 100% due to my wireless card being named eth3 instead of wlan0...I can get everything to work except for the signal strength, since ubuntu thinks its an ethernet cared. (although it show up as wireless connection in the network interface on the top right of ubuntu control bar). It's not a BIG deal but I was wondering if anyone had a fix or work around for this. BTW it is a Broad 4311 using Broad STA drivers if that makes any difference at all...
View 1 Replies View Relatedyesterday without reason my eth0 dissappeared. I read through various threads, tried couple of things, and now its s back as eth3. If I bring up the network on the console it says [OK], but I cant ping my router or access any website.
BTW: During the proccess I removed network-manager-kde, which I regret now (cause I cant install it again w/o network). Even so my network was configured manually, it would be good to have it now for testing connections. The machine also got no CDROM-drive, I installed via USB.
EDIT: I booted up again, and now eth3 is gone again I get the former error message when I restart the network: "eth3: ERROR while getting interface flags: No such device"Same with all other ethX. As far as I can see w/ my basic knowledge, the realtek adapter is present and working. ifconfig only shows me "lo" nothing else.
I have a Fedora system that I just changed the mother board on. The old NICs were eth0 and eth1. Now I have only one NIC that shows up as eth3. The problem is no matter what I do, eth0 and eth1 will not go away and their configs conflict with eth3. I removed Network Manager via yum. I deleted the ifcfg-eth0/1 files from /etc/ sysconfig/network-scripts and /etc/sysconfig/networking/default and profiles. In all of these locations the ifcfg-eth0/1 files keep reappearing after a reboot. I am at a loss at this point how to get rid of these non-existant NICs.
View 2 Replies View RelatedI want to stop incoming ssh to NIC4 (i.e. eth3) and allow it any other interface. I am using following rule
-A INPUT -s 0/0 -i eth3 -p tcp --sport 1024:65535 --dport 22 -j DROP
-A INPUT -p tcp -m tcp --dport 22 -j ACCEPT
But unfortunately its not working.

View 2 Replies View RelatedI've been googling around and can't seem to find my answer. I've got an old ATI 9700 pro that I'm removing from my system. I'm replacing it with an Nvidia GeForce 6200. What do I need to do to switch these in Karmic? I tried switching the cards, but I only get a white screen with the pointer on the new card. I can't do anything else. I'm guessing I have to uninstall the open source ATI driver first. How do I do that?

I put my skype chat on another workspace so I can focus on my school work and I have two windows on my first workspace so that i can alt tab easily but every time someone talks on skype it comes to my first work space and ruins my alt-tabbing comfort. How do I make it stay in its workspace and leave me alone? I rather something in the taskbar blink or if that's not possible, I just want no blinking at all. This is frustrating me since I need my laptop for my homework.

The modem responds with O.K if interrogated in kppp but the response on AT are not there. It does not dial. The modem has been installed as dev/tty/USB0I did compile Gobi loader 0.7 and it did run make and make install without error. The gobi rules are correctly installed and I did copy the firmware in the respective directory. The problem is: did I copy the right firmware? Is there some other problem. How can I diagnose if the firmware is the correct one (I unpacked the windows ones on a windows machine and there are 6)? I do not see usb0 offered by networkmanager (the network traffic is regulated through networkmanager).

View 14 Replies View RelatedI am having issues getting the modem it the dial-in server I have set up to answer on the correct ring. I have the /etc/inittab set:
Code: S1:2345:respawn:/sbin/mgetty -n 7 -x 6 -D ttyS2 yet I have to play with 'init q' and minicom to get it to answer on ring 7. Then a reboot destroys the setting and I have to go through the whole hassle again and it goes back to answering on the first ring.
This is not acceptable. This dial-in server is only a very back door into my network. It is only turned on when needed. Most of the time it is not powered up. When it is turned on it is by a non-tech person with out the ability to jump through the hoops to get it to answer on the correct ring.
Ideally I want this modem to just listen to the line after it stops ringing to check for a data signal and if it does not find it just hang up. If it finds a data signal then establish a connection and all that. That way it does not interfere with answering machine on the line. Google has yielded very little info about setting up dial-in servers. Modems are not used very much any more.
i m using atoi() to convert char value to int. and then passing that int as a swtich variable.switch goes in a case and exectuing that particualr function but returning 0 value....for example: i am finding no of process() and system up time().when switch program goes in system up time it gives right values means correct no of days, hrs , min and sec but when it goes in no of process() it gives 0 answer.

View 1 Replies View RelatedI have a project in school that the requirement is to show the proof of concept of a high availability virtual servers. the guest operating system for the test case will be a Windows variant and a Linux variant that if the main host that hosts both of this VMs fails, both VMs will be restarted on the backup host. Simple enough with VMware vSphere and citrix xenserver with essentials with their enterprise features, But I am not allowed to use a software that one will need to pay-for or is only a trial version, i need to use an open source solutions, and i am not allowed to use virtualbox.
the school has provided me 2 server class 64bit hardware with intel-vt support, i have my laptop for management tools and to also run a virtual appliance for a iscsi target (openfiler as a vm in virtualbox in my laptop).
I have figured that i will use KVM on a ubuntu server as my hypervisor but i cant find any how-to on how to implement a high availability setup that will run a windows variant as a guest. can some one give me a step by step on how to do this.
from my research it looks like i will need DRBD and heartbeat, but i dont know how to use them and if they are applicable in my needs. I wouldn't probably use DRBD since I have a sudo SAN with my iscsi target, so i can probably use open-iscsi.
