Ubuntu Networking :: Cannot Connect To Direct (hotel) Wired Connections Since Running Ppoeconf

Jul 30, 2010

i'm currently travelling in across Japan and facing difficulties connecting to hotel's ethernet connections under ubuntu 10.0.4- when plugging in the ethernet cable nothing happens- rebooting doesn't change anything either.this wasn't a problem before, and i can connect to hotel's ethernet under windows 7 which i'm currently using to post this, but something doesn't work under ubuntu, which is now my main os.

staying at my inlaw's house for a while, i ran pppoeconf to use their optical fibre connection, which worked, but also seems to be the root of the problems i'm now facing to go online via ethernet elsewhere. it seems like pppoeconf disabled something.

Ubuntu Networking :: BTHomeHub2 - Router Not Listed In Wireless Connections

Oct 21, 2010

I'm getting really tired of using windows, I love ubuntu but theres a big problem. I have a BTHomeHub2 and whats annoying is whenever I goto wireless connections there's only a bt home hub but its not my one. and I have tried connecting to hidden wireless network and nothing worked. I have a desktop pc with a usb plug in BT voyager that picks up the router but it will only find the one down the street not mine. It works fine when using Ethernet.

Networking :: Portforwarding Versus Other Options

Mar 14, 2010

i have some servers behind a server/router/firewall at [URL] that can be accessed using port forwarding. they are working quite well. [URL] gets you to the first server behind the server/router/firewall (the former link above).

i would want to make the server at the latter link accessible with its own domain name ie [URL]without having to add :<port> to the end of [URL] because ":" is disallowed for aliasing in the a and cname records at network solutions (my dns?). is port forwarding the best way to reach these servers behind my firewall? is it possible to assign them their own domain name? perhaps some method other than port forwarding should be used?

Ubuntu Installation :: 11.04: Remote Desktop Only Allows Connections As 'localhost'

May 3, 2011

Under 10.10 the settings dialogue for Remote Desktop said that other machines can connect to this one as kubuntu.local or but after u/g to 11.04 instead of hostname or IP it now just says 'localhost' - which won't work for obvious reasons. I use RD a lot.

Also, despite 'Always display an icon' being checked no icon is displayed in the panel. I tried checking 'Never display an icon' closing the dialogue, re-opening it and re-selecting 'Always display' it still doesn't appear.

CentOS 5 :: Tftpd Only Accepting Connections From Localhost?

Jul 12, 2011

Having a problem with tftpd on CentOS 5.5. I am only able to download files from the localhost address.

I have checked iptables (by adding rules and by turning the firewall completely off -- nothing changes) and enabled tftpd logging (by adding -v to the server_args section in xinetd.d/tftp) and I DO see the request coming in, but no response from the daemon. I've also tried upping the verbosity by adding multiple -vs and/or --verbosity 10 to the mix, but all I ever see is the initial request come in, nothing more. I've even tried running the daemon in foreground mode with -L but I get no verbosity then.

OpenSUSE Network :: Router With 2 DSL Connections Not Port Forwarding?

Apr 26, 2010

I'm running suse 11.1 which is configured as a router. Configured are two DSL connections with static IP's and one LAN connection (3 NIC's all together).

Problem: suse firewall will only port forward connections from one of the DSL connections and not the other.

Because I'm running two DSL connections is there something special I have to turn on/enable on the firewall?

Networking :: Can Nmap Detect Port-sharing

Sep 28, 2010

Since I no longer have access to a spare machine to actually test this out on, I was hoping some kind soul might know the answer, or be willing to try it out for me. I'm trying to find out if the port scanner nmap can detect two different services which are sharing a single port. For instance, if I'd managed to set up, I dunno, a web server and an ftp server to both run over the same port, would nmap with version detection be able to detect both of them, or just one?

Networking :: Nmap Showing Wrong Information?

Oct 16, 2010

I'm not too sure if this is the right topic to post in but if it isn't please move it to the correct topic. I recently opened some ports for my Playstation 3 and the connection test on the PS3 tells me that the ports are open . But when I execute this command

nmap -p 0-60000 I get this


Starting Nmap 5.21 ( http://nmap.org ) at 2010-10-16 20:54 AUS Eastern Daylight

All 60001 scanned ports on PS3 ( are closed
MAC Address: **:**:**:**:**:** (Sony Computer Entertainment)

Nmap done: 1 IP address (1 host up) scanned in 4.12 seconds

I could be executing the wrong command or something but I have read through the manual and couldn't find anything that helped. I have tried this command on other machines that I have opened ports for and get similar results except for a few Ephemeral ports (80,443 etc.) which also makes me wonder why these aren't listed as open on the PS3?

General :: Properly Portforwarding The External IP With Iptables

Jul 2, 2011

I am trying to forward all the incoming internet/LAN requests on port 80 to my local machine (running Apache), current iptables work (forward incoming internet traffic to my desktop, but if I try to access it from my local network it won't work. Interface connecting my Ubuntu server to the internet is ppp0 (dialed DSL connection through my router that is in bridge mode) which is connected to the eth0 and eth1 is connected to my internal LAN.


what i was able to gather so far (via logs), is that accessing external server ip directly from the LAN goes directly to eth1 which is understandable (i think). So what i need now (i guess) is an rule that will forward the LAN traffic on eth1 without interfering with the ppp0 prerouting rule (as forwarding all the incoming traffic on eth1 to my local machine will break the internet connection)

Networking :: Setting Up Linux Box As IPv6 Router To Replace Netgear WNR1000 Wireless Router?

Jun 18, 2011

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?

Networking :: Set Up A Laptop As A Router To Connect Wirelessly To ADSL Router?

Nov 6, 2009

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:


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.

Networking :: Network Setup - Router - Wireless Router Card ?

Apr 24, 2010

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 (itself) to, while the wireless router card assigns addresses from to (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 to, 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, 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.,,

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?

Here is a link to (picture) my network diagram. Network Diagram

Ubuntu Networking :: Crossover Direct Connect To Windows 7 Pc?

Apr 8, 2010

Ive just installed ubuntu on a small nettop type pc. It can connect to the internet but I want a direct network connection thru gigabit LAN using a crossover (apparently a straight cable would have been sufficient). Anyway, I have no idea where to begin. The network connection manager in Ubuntu shows Autoeth1 which is right and, if I manually set the IPv4 I can get the PCs to somehow see each other and the 7 pc to give a 'network access only' but that's it.

Ubuntu Networking :: Could Not Load A Single Page, Except Pages With Direct IPs?

Jan 14, 2010

Excuse me if such thread exists already, i carefully searched the forum so i wont create a second one concerning the following problem:So i downloaded (on my new fresh Fujitsu SIEMENS Li3710 running Vista the Ubuntu 9.04 distro.. im a complete Linux noob, but i wanted to give it a second try) so i downloaded it and burned it on the fast laptop, so there wont be any errors caused by low memory during burning I installed and then i went to the Ubuntu desktop - i had all drivers installed. Everything but Amarok sound worked, i turned off my laptop and went doing my job.. The next time i started up my laptop and went on the desktop .. a tradition is to browse the web, so i did that and i couldnt load a single page, except pages with direct IPs i had Skype working just fine and i had a friend there running SuSe and asked him for help. We identified it as a DNS problem, but because of my noobness i couldnt deal with it and i HAD TO switch back to windows, wich i regret so much.

I know that im a noob, but if i have an internet running at its best i can look at forums and resolve my other issues, so im asking for a screenshots on DNS settings so i can fix it the next time i install Ubuntu.Also! I was using cable via PPPoE (and the only terminal command i know is "sudo pppoeconf" ), now im with router, connecting my laptop directly via WI-FI, will i have the same problem and will i have to make settings so i can connect to my router? Because back then i tried to connect to wireless networks and the ones i could connect on XP/Vista/7 i simply couldnt connect on Ubuntu...I really want some real PC knowledge and to use Linux

Networking :: Load Balancer With Direct Routing - LVS-DIR

Jul 16, 2010

I am working on a load balancing project. The type of routing I am implementing is direct routing (LVS-DIR).

The following is a script that sets up the Linux Virtual Server (LVS) or the load balancer:

On both, the LVS and Real Server 1, the firewalls (iptables) are not running.

A few questions I have are:
1) On the LVS, is apache supposed to be running?
2) If so, what would be the ServerName for apache on the LVS?
3) What would be the ServerName for apache on the real server1, is it the server real IP or the VIP?

When I try to access the web content on real server1 in a browser on the LVS, I get Failed to Connect. A connection to the server cannot be established.

The load balancer has two NICS, eth0 and eth1. The real servers will connect to the load balancer via eth1, and the client will connect via eth0.

Ubuntu Networking :: NetworkManager Won't Connect Wired Direct To Cable Modem

Jul 9, 2011

I cannot connect my Dell Inspiron 1300 through the NetworkManager "wired" connection, when I try to go direct to the cable modem. It fails to connect.

If I connect the cable modem to my (linksys WRT54GS) wireless router, and then connect my laptop to a wired port in the router, it connects in seconds, successfully.

This has happened to me 2 other times, when I tried to connect my laptop to a client's cable modem, because my client did not have a wireless router available, in their home.

My wireless works fine. This has me perplexed. I'm using Ubuntu 10.04 LTS and NetworkManager Applet 0.8

I've tried some things to see what is going on, such as "ifconfig" "dhclient" as well as modifying the "Auto eth0" parameters and adding my laptop's MAC address, etc. Results were no fix or solution. I feel like I'm headed down the wrong road. Would someone set me straight? I have a feeling this is simpler than I think.

Do I have to actually reset my own or someone's cable modem to get this to work? I don't want to do that unless there's no other way. Is there? Let me know what commands I can or should run.

Networking :: Old Router Behind New Router - Configuration ?

Oct 30, 2010

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,

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.
