View 2 Replies View RelatedI would like to set a double range of IP address with my DHCP3-server. Now, I have eth0 (which is my only network card) with this IP address : 172.16.93.1 and I have created a second interface eth0:1 with this address: 192.168.3.1. The goal is to give an IP address 172.16.93.X to phones (with option 66) and the IP address 192.168.3.X to the computers.
This is my DHCPD.conf :
ddns-update-style none;
option domain-name "mycompany.com";
option domain-name-servers 172.16.93.1;
default-lease-time 3600;
max-lease-time 2347200;
authoritative;
log-facility local7;
option ip-forwarding off;
default-lease-time 20;
max-lease-time 20; .....
Right now my DHCP server work fine, (I means, no error at the startup ) but the server give always the same kind of IP address, whatever if it's a phone or a computer. I notice something "wired", if I put the :
subnet 192.168.3.0 netmask 255.255.255.0 {
range 192.168.3.100 192.168.3.199;
option routers 192.168.3.254; }
(Which is first in the dhcpd.conf) after the "subnet 172.16.93.0 netmask 255.255.255.0", the server will give IP address 172.16.93.X at all the clients. Is it possible to give more than one IP range with one network card at the same time? And how set the option 66 to only give IP address (172.16.93.X) to the phones?
I'm assuming that the following should block the complete 178.123.xxx.xxx address range.
Code:
iptables -I INPUT -s 178.123.0.0/24 -j DROP
Then I believe that I need to save this change.
Code:
service iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]
However, I'm not so sure that it is actually working based on the fact that there continues to be access to my wiki from that address range. The following is after I made the firewall change.

I spent hours and hours digging through this thread, and other random ones, where everything succeeds. I have an onboard Intel ICH6. Its details are located at: http://alsa-project.org/main/index.p...x:Vendor-Intel (btw, the part of about going and finding your chipset from a dropdown and the green text is a broken link. I think it should point here, instead: http://alsa-project.org/main/index.php/Matrix:Main).
My resolution ended up being, in the sound preferences, to change the Connector under Output from "Analog Output/Amplifier" to "Analog Mono Output/Amplifier" (No Amplifier works too).
I didn't find this advice anywhere. I was going to give up, and was poking around, and saw the mono options. Since onboard speakers are mono, I gave these choices a try. So, hopefully, this helps someone else. I appreciate this sticky; maybe there should be some information about how to find the appropriate sound settings in the guide ... somewhere in the beginning, around where you should check that your volume is up and your mute is off
This is a quote from sound solutions thread. i had this problem too with ICH6 but now that i have sound i have a new issue. While a normal sound range is 0-100% my sound range is about 0-10% meaning that about if i put my volume on 3% it it as loud as about 30% should be normally.
get me understand the short range and the long range links from routing (and routing protocols') point of view.

I have installed Kubuntu Lucid x86 10.4 LTS for the first time. Has anyone got a link that explains how KPackageKit gets the IP address of the repositories? I can install packages using sudo apt-get install xxx OK . KpackageKit tells me I have updates from the repositories. I can select them all and apply , but I get an error that it can't find the repository under a 192.168.100.129:8080 address . Which is not a surprise . I am using mirror.optus.net as a repository and can ping it fine on the command line. So is there somewhere else that KPackageKit maps IP addreses ? I have tried another mirror mirror.aarnet.edu.au and got similar results. My local sub-net is not 192.168.100 and have tried setting fixed IP on the local sub-net and different DHCP addresses and still the same error.
View 5 Replies View RelatedI am running Debian Squeeze with the following basic services running:DNS
DHCP
Samba
Squid
The server is setup with three NICs: eth0 (WAN1), eth1 (WAN2), and eth2 (LAN).The server addresses clients with an IP range of 10.0.30.1 - 10.0.30.254. Some clients will be set with reservations so they fall into the 10.0.40.1 - 254 range.
What I want to do is have any outgoing external traffic coming from the first range (10.0.30.0) to use WAN link 1, and any outgoing external traffic coming from the second range (10.0.40.0) to use WAN link 2.
I have sort of got something working. I have created a bare minimum transparent squid3 setup on port 3128, and set the iptables as follows:
Code:
iptables -t nat -A PREROUTING -i eth2 -p tcp -m tcp --dport 80 -j DNAT --to-destination 10.0.0.1:3128
iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128
iptables -t nat -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128
I can get internet access, however obviously it only goes through one WAN link. It also seems slower than it should be. I experimented with tcp_outgoing_address, but seemed to not be my friend.

Suppose I have the usual wifi router, but unfortunately the signal doesn't cover the whole house; a solution is a range extender, but I thought: if I have a laptop, placed in the same room where I would put that range extender, can't I use THAT as a range extender too? After all, range extender at the very heart are "stripped-down" routers, which in turn are stripped down PCs equipped with a stripped-down version of the Linux Kernel...
View 4 Replies View RelatedI want to configure a VPN over the Internet.I installed the 'openvpn' package, generated the key file, transfered it by a secure way to the client, and setted up the configuration file.
So, in that configuration file I input the IP addresses of the tunneled interfaces. Both IPs are static in the tunnel.
Then, I've heard somewhere that I can assign a dynamic configuration IP for the client. I do this registering a range.
Well, when I tried to change static IP to dynamic IP (changing '192.168.0.2' to '192.168.0.0/24') in the configuration file, the OpenVPN didn't work.
Obviously I don't know what I'm doing, and I really, don't believe that simply changing the IP will make it work, but I tried.
I hope I explained my problem as well.
My configuration file:
# OpenVPN Server Configuration File
dev tun 0
ifconfig 192.168.0.1 192.168.0.2
cd /etc/openvpn
secret key_file
In client I execute the 'openvpn' without the '--daemon' parameter.Then I want that my client uses a IP in a range (192.168.0.0/24, for example), instead of a static IP (192.168.0.2).I also thought to use a DHCP server, but I'm not sure that will work.
if an admin decides this is security feel free to move, at the moment I can't decide where so posted here...On my laptop (msi-u100) my bluetooth stack creates rfcomm0 but is not applying the correct context label to it so selinux is bitching.

I want to plot a set of data in only one plot.The problem is that some points of the data should be better plotted in a linear scale (lets say 0 to 100,000) but there are other data points that, exceding the value 100,000, would be better plotted in a logarithmic scale, as they goes in the range 100,000 to 500,000,000. Let's say the data is:
Code:
X Y
0 100
10000 80
20000 75

Is there a way to plot all these points in the same plot in only one X-axis showing two different ranges in that axis: linear: 0-100,000 logarithmic: 100,000 - 1,000,000,000?The axis would be read, for example, as:
Code:

I want to build a bash script, which can ping a range IP adresses which will be filled in by the admin. If there is no IP-adress filled in, then the script must ping the subnet where the system is logged on. So if my ip is 192.168.1.6, then the script must ping from 192.168.1.1 till 192.168.1.255 Or else, if there is given a beginning and ending ip it must ping that!
The first part of the bash script is to ping a given range (see below). But there is one problem, how can I tell the script to ping from $begin till $end, [..] is of course wrong! But what must be filled in there???
echo "Enter beginning IP-adres:"
read begin
echo "Enter ending IP-adres:"
read end
ping -c 1 $begin [..] $end
The second part is to find my own ip and ping the whole range.. How to do that? I only can find my own IP, but I cant ping the whole range,, how to do that?
#!/bin/bash
ifconfig | grep 'inet addr:' | grep -v '127.0.0.1' |

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.
Consider the following program:
Code:
#include <stdio.h>
#include <stdint.h>
[code]...
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.

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.
