Fedora Networking :: Cannot Connect To Local Computers But Can To Internet?
Sep 28, 2009
I am using Fedora 11 all upgrades, wireless network WUSB54G network adapter. I can get to the internet but cannot get to any Windows (192.168.1.100) or Fedora 11 (...104) computers, printer (....101, 105). Here are the tests I have run.
[root@Fedora2 sbin]# ping 192.168.1.1

I have a Dell PowerEdge 1650 server with 3 NICs in it. I am trying to use one NIC (eth0) to connect to the internet, the second NIC (eth1) to share the internet connection to a LAN, and the third NIC (eth2) to connect to the LAN.
It is running Ubuntu server 8.10
The problem that I'm having is that NetworkManager (version 0.7.0) keeps setting eth2 as the default connection, and then I don't get any internet at all from the server.
My main goal is to be able to share files from the server to computers on the LAN. The secondary goal is to have a virtual machine hosting a Halo server, connected through eth2, so that it can host LAN games. But that is a secondary goal after I get the connections to work.
I've been looking around and finding other people who have done bits and pieces of this, but not the whole thing. I had been hoping to simply use the NetworkManger, but I don't mind editing config files.
Also I can't seem to find any good instructions on editing the /etc/network/interfaces file. The man file is incomplete, and everything seems to point back to the man file.
- CAN connect to other computers - ssh and vnc over the home network (via D-link 524 router). - CAN get an IP address via DHCP - CANNOT get internet connections - including router at 192.168.0.1 - CANNOT even ping router (but I get an IP address - weird) - Other computers on the network CAN access internet - Live CD could not access internet
results of ifconfig
I am wondering if his ISP could be doing this - he has received a warning letter about bitorrent. Could the isolate a single computer behind a NAT router?
This is the results from dmesg:
I have tried:
- to set proxy settings as "Direct internet connection" - disconnecting power to (including 30 sec wait): modem, router, computer + unplugging ethernet from computer - Live CD (he only had an old one 7.10) which also didn't connect to internet, but as I am remote, I couldn't do any more. We are downloading a 10.04.1 iso for him to burn tomorrow, and will try that again. - Uninstalled Crashplan which was the last software that we installed (and it was working ok).
I am currently ssh'ing into another computer on the network that IS working, and then ssh'ing into my Dad's computer - including a VNC session (tunneled through both machines and router).
I have 2 10.04 computers and one win 7 and one vista computer: The win computers can see each other and the ubuntu computers, but the ubuntu computers cannot see each other or the win machines. The ubuntu computers connect to the internet fine and can ping each other. I cannot find settings to correct.
I Have Ubuntu 9.10 Server installed and for some reason after updating our server with the ubuntu update manager, we can no longer connect to the network via remote desktop, let alone not even able to ping. We are actually able to connect to the internet itself just fine so I dont understand why this isn't working
I have been trying to remotely access another computer (which is outside my local network) with ssh and have not succeeded. I've done everything I've seen nothing to suggest and as I opened port 22 on both computers, I have ssh configured so as to allow access from any computer (with password) and tried to log in using the external IP (the encounter with these online pages of "what is my ip"), I have a firewall turned off, the pc from which I agree is Fedora 14 that I want to access MacOS 10.5.8.
I need this because I'm running a very heavy program at the university that I can not run on my personal laptop, but do not want to have to go every day to college for this.
I have dynamic internet connection. In my network one machine run glassfish server in port 8080 (it IP address 192.168.1.3). If I type http://192.168.1.3:8080/ that load my glassfish server page. What I want is using dynamic IP like http://<DynamicIP>:8080/ load my glassfish server page. How can I do it ? My router is Dlink GLB-802C > I haven't good knowledge about network.
Trying to share my internet connection with other computers on my LAN. I've tried doing this with Debian, Ubuntu & Fedora so far...
My Intended Setup is as follows;
The Problem: So far I've not been able to get an internet connection from any computer connected to the HUB. I currenty have Fedora 13 on PC1 but have also tried with both Ubuntu 10.04 & Debian Lenny. I am open to using any Linux based distro on PC1 as long it has a Gnome Desktop. eth0 on PC1 can be Static or Dhcp, but I would prefer to set Static IPs on eth1 & all of the Client PCs
To the best of my knowledge I have enabled ipv4 forwarding in sysctl.conf (& some other changes);
All changes I made to the Firewall (all other Firewall settings are still at default, no custom rules added yet);
Router is set up to assign dhcp from 192.168.xxx.100 & 192.168.xxx.200
At the moment I have only 1 PC attached to the HUB. It's Ubuntu 10.04 (PC2) It's details are; ip 192.168.xxx.103 netmask255.255.255.0 gateway 192.168.xxx.101
Thus Far I can't ping 192.168.XXX.103 from PC1 & I can't ping 192.168.XXX.101 from PC2. (unreachable) I have an internet connection on PC1 (of course)
This is my first attempt at a server, and I running Ubuntu 10.04 server. I had to reconfigure my network, so now I am attempting to use it as a server. I have a Linksys WRT54G2 connecting various machines-- Windows XP, Ubuntu builds, and LinuxMint 10 Julia.
The long and the short of it is that the server connects to the Internet-- I can get updates and install programs via terminal. The server also connects to the router, as tested by pings. The client computers all ping back and forth nicely, and I can access the file share via FTP from the local side and externally (this is part of a larger network).
How can I get it so that my client computers can access the Internet through the router and server?
In Ubuntu 10.10, I have my printer, an Epson D120, shared. I can print from the computer itself, but other computers cannot print to it. Both Ubuntu and Windows machines have the printer successfully installed. They can access it, I can access CUPS from all these machines and the the job queue even reports the jobs sent from these computers. But the page count is unknown and nothing is printed, although it says the job is completed.
I'm quite desperate to get this to work. It would suck if I need to go back to Windows just because some minor thing goes wrong. I really don't understand why local prints are OK, but prints from the network are not working.
I want to be able to access my desktop from work so I first set up a DNS. I can ssh into my own computer and using the ip address but when I try to ssh using my DNS (this is from my home wireless which is Linksys E2000), I get the following error:
debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to ****.com [18.104.22.168] port 50000 debug1: Connection established. debug1: identity file /home/andy/.ssh/id_rsa type -1
I set up the settings on the Linksys to accept DDNS but I am thinking there might be something else I overlooked? I do not understand completely what is happening to debug this. It seems like it initially accepts the connection and then something strange occurs.
i have two computer first one is the main computer, he is connected to the internet throught DSL ubuntu 10.10 beta installed
the second is ubuntu 9.10, and i want this computer to connect to the internet of the first computer
they both connected to a B-FOCUS router 270pr but i dont want to make the router to be the one that connects to the internet i want the first computer will connect to the internet and the second will be accessing the internet of the first computer connection.
I have 2 computers,one is connected directly to internet with a classic rj45 cable. it has a usb wireless dongle too (ralink)the second has a usb wireless dongle but no network card.is it possible to connect the second computer to internet through the first? (second computer connect to the first computer through wireless and through it to internet)infact in first computer share internet with usb dongle.
i have two machines both on ubuntu 10.4 connected to a network via port switcher, 2 rj45 network cables auto eth0 is setup to share with other computers, i can ssh in and out of both, so the network is all running but i want to know how to share my single dongle internet connection between the 2 computers
While using Ubuntu two other computers lose their connection. One (main) is connected to the modem, other from the switch to the wireless router, and the one with ubuntu wired via switch. Currently connected with Windows 7, other two are connected. Once booted into Ubuntu rest of the computers disconnect?
I have an old HP pavilion laptop (2005) that was useless.I installed Ubuntu 10.10 on it and it became a working computer again. It was excellent, snappy, it was as if I had bought a lower end modern laptop.Internet was working great.I did not have any complaints (in fact, I thought that a modern computer running Ubuntu would beat my so adored macbook, speed wise). For some time I had 2 efficient computer, a macbook and the hp with the Ubuntu OS. So on the last weekend of February, my internet got extremely slow on both computers. After that annoying weekend (February 28) the internet on my mac was good again,however, the internet on my linux continued to be messed up.I tried disabling IPv6 on my machine and on firefox, tried the openDNS, the MTU stuff, but nothing.I even formatted my disk and installed ubuntu again (all this using the installation CD).However, apparently the installation CD uses some of your existing configurations (for example, the layout of the close, minimize,maximize:menu buttons on the corner of windows did not go back to default). So I'm guessing whatever was messed up with the computer didn't change back to default or the previous configuration when I first installed ubuntu. To give you an idea of how slow the internet is, installing alien (terminal installation),I got low speeds of around 150B/s (no typo here, it was bites, not kilo bites) and the fastest around 5,000B/s. The fastest I got was downloading chrome at 6kB/s but that didn't last even a minute. So given that these transfer rates are obtained both on firefox and the terminal, I'm assuming it is not a browsing problem.
A thick headed solution, would probably be to install windows again to get the network configuration to "standard" and then install Ubuntu formatting the disk again (using the CD).I'm using ethernet,so,thinking it might be cable problems, I did try to use the cable that was on my mac on the machine with linux. No success there.
If I have a desktop with a USB wifi adapter connected to the internet through an ethernet cable, is it possible to create a wireless network using the adapter that will allow other users to connect to the internet through mine? I'm in a fairly low-tech place for the next few weeks and getting a router isn't likely.
If it's possible, anyone have links or instructions for how to do it?
I installed fresh copy of fedora 11. I can't activate or deactivate ethernet from system>Administration>Network. Why is this............I can connect to internet directly by enabling network icon on right topmost corner. Even doing so dosen't guarantee connection at times. What could be wrong here ? Also my network icon shows it is disconnected whenever I start my computer. Cant fedora 11 just connect to the internet while it boots ?
I just installed Fedora 14 on my laptop as a Dual Boot with Windows 7.The problem I am having is that I can't get fedora to connect to my wireless internet.I can access it just fine on the windows side.On my Fedora desktop at the top there a little icon with two little computer monitors there is also a little x by them. Here is whats in the computer as far as networking devices:
Realtek RTL8191SE Wireless Lan 802.11N PCI-E NIC
I also have a:
Realtek RTL8187 Wireless 802.11b/g 54Mbps USB 2.0 Network Adapter
No matter how I configure settings it don't work.If I have to download something on the windows side to fix this please let me know how to get it to the linux partition.
I have installed fedora 12 recently. after installation i tried to connect to the internet using BSNL broadband connection. I filled in the details such as IP, Netmask, Gateway and even DNS servers. In the services also I ensured that the network manager services is on. However even though my computer cannot connect to the internet. I then tried the ping test of the modem from the address 192.168.1.1 and found that the ping test is successful. Then i tried the network administrator and there I noticed something unusual.
There are two options in the devices eth0 and eth1 thats ok but the unusual; thing is that the Activate (green button), Deactivate (red button) and even the delete buttons are in the background and I cannot select them. Isthis the problem for the network connectivity.

I have an old laptop with wireless, 2 desktop computers without wireless and an Allied Telesyn gigabit ethernet switch (specifically AT-GS908GB). Is it possible to hook the 3 computers into the switch and use the laptop's wireless as the internet source for the other 2?
I have internet on my ubuntu machine (eth0) I am sharing with (eth1) My windows computers are getting IP addresses via DHCP from the Ubuntu Machine, and I can see (and use) samba/windows shares on all computers. Internet connection is not working on any of the windows computers.
I have eth1 set to "shared to other computers" under the IPv4 settings
I have installed Fedora 10 on my Intel system. I am not able to connect to internet from it. Mine is a broadband connection with ADSL+2 modem. I could connect once but afterwards it was deactivated and I got following bug report.

I've been trying to connect to the internet in Fedora 10 for the last week but can't figure it out. The OS has automatically connected to the internet a couple of times but now does not connect at all. The LAN ROM Boot option is enabled in my BIOS and am using a speedtouch 585v7 router provided by my ISP, I have an ADSL router and it's a standard ethernet connection to the router. What do I do to connect to the internet
I have just installed Fedora 10. After the installation I was able browse the Internet. However, I did a update: yum update and downloaded 287 updates. However, when I rebooted I could no longer connect to the Internet. I went to network manager and looked at the details of my connection. Everything ok there. IP address, DNS, etc. However, I cannot connect. I have windows xp running on the same system. I can still connect, so there is nothing wrong with my Internet connection.I am using Fedora 10 22.214.171.124-170 There is one thing I have noticed when I shutdown is I see this: "Network manager Int PIC disabled" However, this is only displayed for a few seconds before the computer swiches off.
