Ubuntu Networking :: Get A Router Configured Using Webmin
Mar 19, 2010
I'm trying to get a router configured using webmin this is how far i've gotten if eth1 is the iface connected to the modem and eth0 the internal LAN interface:I set net.ipv4.ip_forward=1 in /etc/sysctl.conf
I did a echo 1 > /proc/sys/net/ipv4/ip_forward
I configured following rules in webmin:
Incoming packets (INPUT)
AcceptIf input interface is lo
AcceptIf input interface is eth1 and state of connection is ESTABLISHED,RELATED
[Code]....

I encountered a a dependency issue when trying to install Webmin on Ubuntu Server Edition 10.04 Beta1.
When you try to install webmin, libmd5-perl is not available in any of the lucid repositories:
I resolved the dependency prob by adding the following repository to my /etc/apt/sources.list: deb [url]
Then I did a sudo apt-get update then sudo apt-get install and libmd5-perl installed fine along with webadmin. BTW. I got a GPG error when doing a apt=get update because I did not import the public key for the debian repos I used to get libdm5-perl, which doesn't matter to me as I commented out the repos once I got libmd5-perl installed.

I have had webmin running previously but i just recently installed Unbuntu server and i am now trying to install webmin. after typing this to install webmin sudo apt-get install webmin it started doing its thing and then it halts.
Giving me the following message: "Package webmin is not available, but is referred to by another package. this may mean that the package is missing, had been obsoleted , or is only available from another source."
The first thing i did after installing webmin was edit the sources.list
Then i tpyed sudo nano sources.list I uncommented everything with "deb" in front of it
I also uncommented
deb cdrom:
I then typed this sudo wget [url]
After getting that i typed this apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl
Then i tryed to install it and got that error.
I also tryed install it using this tutorial [url]
When i got to the part when i need to type
sudo apt-get install update this is what happened

Because of the configuration of my house, I need two routers.I have a DLink ADSL router as my main router and the Belkin N1 as my repeater.I have set up the IP address in the Belkin to be 10.1.1.10 - my DLink is 10.1.1.1. I have disable the dhcp in the Belkin and set the DNS as ISP provided. [URL]..I have set the channel to 11 and in the Ubuntu Network Manger I have set the IPV4 to Link Local Only. I can see the Belkin and connect with my PC.but it will not take me through to the internet.

I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.
As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?
My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?

I have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).
I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.
I have added this to /etc/sysctl.conf on the laptop:
net.ipv4.ip_forward=1
Then I tried this on the laptop:
sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT
This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.
But this doesn't work. The connection doesn't even establish between the laptop and the desktop.

I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

These r IP provided by my ISP that i've put on Fedora 8:
WAN IP:xxx.xxx.xxx.17 (eth0)
Subnet:255.255.255.252
Gateway:xxx.xxx.xxx.18
Valid static(public) IP set of 2:
IP:xxx.xxx.xxx.147 & 148 (eth1, eth2)
Subnet:255.255.255.240
i want to run xxx.xxx.xxx.147 as a web server & xxx.xxx.xxx.148 as a ftp server. but I'm able to ping only xxx.xxx.xxx.17(WAN IP) from outside world. Can any1 tell me that how can i bring my 147 & 148 IP online without router.

I'm pretty new here and I want to be able to set up my Linux box as a shared drive (so that I can use it as a backup drive to my win7 machine). I'm using webmin to administer Samba and I get to the point where it shows:
Share Name Path Security
homes All Home DirectoriesRead/write to everyone
When I go to my win7 machine it I can browse to the machine (called jira2) and see the folder called homes, but when I click on the folder it says Windows cannot access \JIRA2homes. if I expand the details it says Error code 0x80070035 I am running Ubuntu 10.04.

I have configured bridging based on information from a few web pages Google found. Traffic is being seen (using tcpdump) on both interfaces that are configured. However, the traffic is not going between them. What could be missing?The bridging machine has 3 NICS: eth0, eth1, eth2. eth0 is configured normally with an IP address (I can login via ssh to it just fine). The bridge is named br0 and uses eth1 and eth2 (a dual NIC card for convenience identifying which NICs are the bridge).
A script executes these commands:
Code:
bash-4.1# /etc/rc.d/rc.bridge-up br0 eth1 eth2
EXECUTING brctl addbr br0
[code]...

I have a hub with some VoIP phones attached as well as a machine that is used to record the calls. This all works fine as all packets coming to/from the voip phones are also seen by the recorder so it can process them as necessary.
What i want to do is put another machine between the hub and recorder and have it act as a transparent firewall. So far i've managed to successfully set up a bridge on ports eth1 and eth2 and all the packets destined for the recorder go through the bridge fine. The problem is that the bridge is acting as a switch so the packets from the phones are received on eth2 but don't get retransmitted on eth1. Is there any way to configure the bridge so that all packets received on eth2 are transmitted on eth1, i.e. have it act as a hub instead?

I have kubuntu 8.10 up and running however I am not able to get internet configured. this is on a laptop i re-purposed. I have ubuntu on a desktop that works just fine. however w/ kubuntu no such luck. i realize its just kde vs gnome and am connected to the same router and such so all should work just fine, but alas it doesn't.the desktop is configured using dhcp, not static IPs.
the laptop w/ kubuntu isn't recognizing eth0
>cat /etc/network/interfaces displays:
auto eth0
iface eth0 inet dhcp
after restarting and running /etc/init.d/network restart.there is no resolv.conf... i understand dhcp should auto-create this? furthermore running ifconfig desplays no results ?

I am using an eeePC with Xubuntu Lucid and I just configured a wireless network to run with WPA & WPA2 (wireless access point NetGear WG103). It tries to connect and then comes back with a request for reentering the passphrase. I have had this once before in a pub. The way I read this the driver is getting confused how to authenticate.

I've moved a linuxbox from being my gateway (nat, etc) to behind a new gateway (a DD-wrt router). For transparency purposes, I'd like to continue using the old box services, and just have the gateway in front of it.
Here's what I did:
The newgateway is setup for class C, 192.168.0.0
This configuration works, but sometimes it doesn't and I haven't figured out why yet.
At sometimes, clients on the LAN get throughput rates with very little speed loss (using speakeasy speed test). They will run at 33M on the LAN, running through both the newgateway, and the oldbox, and get about 35M with directly connected to the cable modem.
Other times, it seems nothing can talk with anyone, and I am not sure why.
I know what I have done is a little unconventional, but it's a transitional thing, and I am not sure it is the cause of the problem, although it was the last things changed.

My son lost his USB Wireless stick for his Computer. I had thought I heard that if you had a second wireless router, you could use it somehow to detect the wireless router you have already set up in your home (like using a wireless card)? Is this what Ad-Hoc is? Either way, can this be done and if so how? I use a WRT54Gx2 Lynksys router and have a TRENDNET TEW-432BRP wireless router and also a spare D-link DI-514. I use ubuntu 10.04, and also wanted to know if I connected one of the router to his on the LAn port could he connect msaybe through an Ad-Hoc on my local computer here? He uses XP on his. I'm a newbie to linux and networking in general.

Two machines:
fedora.local = F14 default
mingisapsycho.local = Mac OS X 10.6.4
I want to be able to ssh/scp between these two machines using:
ssh -l login fedora.local
and
ssh -l login mingisapsycho.local
rather than using IP addresses. Neither of these works, from either of the two machines. This does work between Mac OS machines. And I can ssh if I use IPs. So it seems that by default Avahi is not configured even though it is running? I really don't understand. By "does not work" I mean I get on both machines: ssh: Could not resolve hostname blah.local: Name or service not known

I would like an old desktop box to use my laptop as a router to access the internet. Here is my setup:
I have one ethernet port in the side of my laptop which I want to use to get internet access to my desktop computer. The laptop is connected to the LAN via a wireless link. Both systems run Linux. The desktop autoconfigures itself using DHCP. The laptop is a Kubuntu system. I do not have any crossover cables, though wireshark on the laptop sees the DHCP requests from the desktop just fine, so I doubt that I need one.
What do I have to do to make this work?

I added an init script numbered just before bind9 starts, which needs to see the ipv6 link-local address on eth0. Sometimes this address is not configured, yet. In all cases it eventually is configured.
I am unable to find any script that is configuring the ipv6 link-local address (which is in part based on the MAC address). Does anyone know if there is some script or program that is supposed to be doing this, or is it an internal kernel function?
One workaround I am considering is making this init script go into a loop around sleep 1 to keep checking for the ipv6 address. But I'm concerned this might cause some problems. Any suggestions? I don't want to let it move on to start bind9 until the configuration this script does (more ipv6 addresses) is done.
This is on Ubuntu 9.10 server (for which there is not a prefix choice).
