I've got a problem with 'seeing' other machines on my Network. I have two laptops both with F10 on them however I can't ping either of them. They can connect fine to the internet and ping the router, they are both on the same subnet with Firewalls disabled on both machines. When I try to ping it says: "Destination Host Unreachable". I've tried firing up Wireshark to see if that will give me any clue but even that doesn't show any packets whatsoever from the other machine across the Network. It's like they are completely invisible to each other.

I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.

I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."
I am trying to install some NVIDIA drivers on my machine. I went through the process and got this message:

I was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future.

Google Chrome could not connect to internode.on.net
As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)
ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:

Now, a couple of weeks ago, my neighbour has changed the password to this W-LAN and since then ubuntu is unable to connect. The network is being recognized, but after the request to unlock a key for the network manager (besides, how can I unlock it once for all?) there comes the window with the request for the network-password, after typing it (correctly), nothing happens. The request for the password comes two more times and then ubuntu states that it is unable to connect.

- On Windows I and my neighbours get the connection
- My Ubuntu is able to connect to all other W-LANs
I have an Ubuntu server dedicated to running an openVPN server on my VMware ESX 4 host. On my Windows clients I am able to connect to the VPN; however, on my Ubuntu 10.10 workstation I am unable to connect. Here is what I have done. I have network-manager-openvpn and dependices installed as well as the openvpn package. When I hit the add button in the network manager for VPNs, I fill out all the needed information, but am unable to hi the apply button. I have also tried using the openVPN method for connecting. I download the client.ovpn file from the VPN server, and issue the following command:
Code:
openvpn --config client.ovpn
It asks me for the authentication user and its password and produces this:

I have been using Windows XP, and last month i had Linux Mint installed. I was connecting to the internet with an external modem and everything was running fine, until while experimenting with the settings,i bust the whole thing. What i did was to do a "right click" on the 'computer icon' at the bottom right-hand corner to disconnect and from that day i am unable to connect from Linux, but i can still do it under Windows.I had done the same thing under Windows but after going to the 'control panel/network settings' i managed to get the thing working.I went to the 'control panel' in Linux, and under 'network ' i get the message: "Auto eth0 => never". i have been trying to 'edit' the 'settings'

Initially I thought that I need to upgrade CUPS and even downloaded its latest version (did not installed it though).
My trouble shooting started with the ping then telnet followed it. Following is the output of telnet
Code:

Trying 10.x.x.x...
Connected to 10.x.x.x.

I tried to telnet by turning off the firewall but no good. Hope someone has a solution to this issue.
BTW when test page print job is viewed in CUPS the following is the message.

Just throwing in a quick question to see if anyone got any ideas about this.I'm unable to create a remote X session with TightVNC viewer. The local computer is a windows XP box and the remote server is running Slackware 13.
Using Putty on the XP box to connect to Xvnc through a ssh tunnel works just fine. However, when I fire up TightVNC viewer and try to connect to 127.0.0.1 as I'm used to, TightVNC viewer is unable to establish a connection to X. I'm puzzled.
This has worked when I used another XP box as local computer. I'm running all within my LAN. Can this be a firewall/iptables issue? I've obviously posted this in wrong forum category. Sorry about that. Starts this thread in server category too.

I am playing around with transparent proxies, The current way I am doing things is the program makes a request to a computer on port 80, I use
Code:
iptables -t nat -A OUTPUT -p tcp --destination-port 80 -j REDIRECT --to-port 1234 to redirect to my proxy that I am playing with. the proxy will send out a request to port 81 (as all outbound port 80 are being fed back in to the proxy) so I want to do something like
Code:
iptables -t nat -A OUTPUT -p tcp --destination-port 81 -j DNAT --to-destination xxxx:80 The problem lies with the xxxx part. How do I change the destination port without changing changing the destination ip? Or am I doing this setup completely wrong,
I am doing a university course and am struggling to find a method of sending 1 message down route A and then the next message to the same destination via route B, alternating between the two with each new message sent.I am going to use a Linux computer with two Ethernet cards connected to two different networks via a routers and then to the destination host via a switch.
View 4 Replies View RelatedOn my system, I have built my own tunneling protocol, where I relay packets over a non-standardized but verified medium. What I do is capture the packets using iptables and NFQUEUE, relay them over my medium, and at the other end I reinject them using raw sockets. The packet going into the tunnel is exactly the same as the one coming out, verified. The problem is that this doesn't work for ICMP Ping (Echo Request) if the destination of the ping is the same as the tunnel endpoint. If the destination is not the same as the tunnel endpoint, the ping packet is rerouted and arrives as it should at the receiver, and the ping reply comes back to the sender. Does anyone know whats going on? Isn't it possible to send raw icmp to yourself? If not, anyone have an idea what I should do instead?
View 1 Replies View RelatedI have 5 1955 blades in an enclosure for an custom application cluster.All were running Centos 4.4 no problem.We wanted to start upgrading them cleanly to 5.5 so two of them got fresh installs of 5.5.The installs went well enough, no glaring errors.However they can only ping each other! The network settings are fine, no firewall or selinux. I'd run the info script but I can neither download it to them nor paste it in via kvm.Standard static entries, virtually identical to their 4.4 brethren. They ping each other so network drivers are fine, no built in switch configuration changes. It has to be some kind of network configuration issue that i'm just not seeing.
Edit* When i try and ping anything else, including the other blades, I get Destination Host Unreachable.

When I try to connect to any Wireless Networks in Fedora, the option at the top of the screen is grayed out. I can only connect to VPN, a hidden network, or create a new wireless network. My wireless works fine on the Vista side, so I am a bit confused at this

First off, I should state that I am still using Hardy. I realize that it is many versions from the current release, but my schedule is full and provides little time to ring out a new distro and considering the nature of my problem I don't see much need.
The problem is that I cannot connect to my WPA home network. The wireless card is working because I can connect to any WEP network and before upgrading to Hardy I could connect, although not at first.
Have recently installed WICD which has not helped. WICD tries to connect but reports that it cannot obtain and IP address. Network Manager did not report anything but did seem to translate the password into an encrypted key (saw posts relating to this before but no obvious fix) Since switching to WICD I have not had the opportunity to test connection to a WEP network.
I do not wish to change the security of my home network to accommodate the operating system.
Currently I have an Acer Aspire One netbook with Windows XP on it. I want to switch to Ubuntu, so I have the OS on a flash drive and I can run it fine. The only problem is,I cant see any wireless networks in range. I know the router is working because I can connect with Windows fine. A notification also pops up telling me i have to install missing drivers. But when i click on install, the progress gets to 99% and fails. It says i need the Broadcom B43 driver, but i don't know how to get it.

I just dual-booted my Acer Aspire 3810TZ laptop with Ubuntu 10.04. When I first tried to connect to my home wireless network, it connected fine. However, now whenever I start the laptop, it will not connect. The network appears in the available networks list, but it fails to connect. I know the network is ok, because I can still connect to it fine from Windows.
My network adapter is Intel Wifi 1000 BGN. Apparently (from [URL]) the drivers for this card should be part of the distribution.
I can't understand why it connected once, but (without any changes to the system at all) it won't work now.
