Fedora Networking :: 10 Terminal "error: The Network Appears To Be Unreachable"
Nov 12, 2009
I recently installed Fedora 10 and I'm trying to install a driver for my HP Deskjet F4200 Series All in One printer. I downloaded the proper hplip file and when i go to install it in the terminal it gets to the very end where it is trying to install the missing required dependencies. When it checks for the network connection it comes back saying "error: The network appears to be unreachable. Installation cannot complete without access to error: distribution repositories. Please check the network and try again."I am connected to the internet through hardwire cable (also tried it through wifi) and have no trouble accessing internet through mozilla or downloading packages elsewhere. Any ideas on why my terminal won't recognize my internet connection??

I installed Fedora 10 and are using KDE. I struggled to get my network up and running - error for ping was "network is unreachable". I eventually got it right by modifying my ifcfg-eth0 file manually.
Now I'm trying to install with yum, but yum fails to connect, probably because of the proxy. I've set the proxy in <System Settings><Network Settings><Proxy> but it doesn't allow me to also add the authorization - greyed out. I've chosen the manual configuration of proxy.
1. How can I enable or allow the adding of authorization in the proxy dialogs or
2. Where is the proxy file which I can modify from command line (and how)?

I am plagued by the following error when attempting port forwarded connections to my minecraft server. Port forwarding is good and test ok on router based firewall. No iptables entries. Natty N, all updates current.
[INFO] Disconnecting CascadianNW [/184.100.247.218:57787]: Failed to verify username! [internal error java.net.NoRouteToHostException: Network is unreachable]

Some discussion indicate jvm network connection issues related to ipv6, but they are old posts.

I use DNS on my server as a chasing DNS so its not fully configured. I seem to be having trouble with IPV6 addresses. I'm guessing this is linked to the 6to4 tunnel I have set up to my windows box, but I'm not really sure.
Code:
May 21 18:00:16 hyrule named[1148]: error (network unreachable) resolving 'D.ROOT-SERVERS.NET/AAAA/IN': 2001:dc3::35#53

I've got router with: eth2 - local network (192.168.1.1), ppp0 - uplink (x.y.z.a)
my firewall:
Code:
# Generated by iptables-save v1.4.5 on Mon Jan 11 12:22:25 2010
*raw
:PREROUTING ACCEPT [1038480:666298388]
[code]....
somehow iptables -t nat -A PREROUTING -i eth2 -d x.y.z.a -j DNAT --to-destination 192.168.1.1 helps, but imho there should be some other solution. kernel is 2.6.31.6, architecture is x86_64.
P.S. i've also tried iptables -A POSTROUTING ! -d x.y.z.a -s 192.168.1.0/24 -j MASQUERADE that didn't help either.

I've been having a lot of trouble with getting wireless networking devices to work. I guess I have a lot of company, since mfrs don't seem to be very interested in supporting Linux.It seems that one common symptom is that, when I try to "Ping" using the Terminal, I get "network is unreachable".Does this mean anything specific, or is it a general output whenever the network is not carrying on two way communications? Does it mean that the wireless interface is down? Does it mean that the wireless hardware is not transmitting? Not receiving?

My ubuntu installation was running fine with the Belkin F7D1101 v1 after using this install method:[URL]..But, after allowing ubuntu to autoupdate many programs (don't remember which ones), the device stopped working. I checked all of the commands in the link above. They are all still functioning. dmesg throws no errors, but it terminates with
<code>ADDRCONF (NETDEV_UP): wlan0: link is not ready</code> Are there any network files which may have been overridden from autoupdate? iwconfig wlan0 shows "Access Point: Not-Associated" What output can I show you to help me find the problem?

I have a network printer directly connected via ethernet cable to an Ubuntu netbook, but pinging the printer fails, giving "Host Unreachable". The network light on the ethernet socket is lit green, and there is nothing else cable-connected to the network - just a simple cable connection between the netbook ethernet socket and the Network printer (a HP Laserjet 4200n). Ping works fine if I plug the cable into a different machine (a Win XP box) and ping from there, so it's not a cable or IP address problem.
This sounds simple enough and should work, but I'm stumped. Clues, anyone?

I'm experiencing massive latency/unreachable problems on my Linux machine. It's true for all network connections, here's an example of me trying to ping my router:
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.
64 bytes from 192.168.0.1: icmp_req=1 ttl=64 time=15115 ms

64 bytes from 192.168.0.1: icmp_req=3 ttl=64 time=13107 ms

64 bytes from 192.168.0.1: icmp_req=5 ttl=64 time=11108 ms
[Code]...
I've tried now with both the maverick default kernel and 2.6.37-rc5 kernel (both 64 bit), same result. If I take the card up and down (ifup, ifdown) performance is restored for a little while, then it's back. I've tried changing cable, network card and router port but no luck.

I am building a v2.6 kernel floppy disk distro to run on a 1992 computer. FWIW The specs on the computer are
* 66 MHZ processor
* 12 MB ram
* 400 MB HD
* EGA monochrome video card
It runs Linux quite nice actually. I want to get it online with a null modem cable and use the other Linux box as a gateway to the internet. I have networking, TCP and slip support in the kernel. I do now know if I have all the needed network configuration files. I am able to ping 127.0.0.1. If I try to ping the other computer, I get a "network is unreachable" error. Tell me any commands to run on either box and I will attempt to do so. Remember the old computer is running a stripped down toolset since its only two floppies worth.

I have recently installed 10.04 on an old box I have sitting around and wanted to include it in my home network. After struggling with Network Manager I went in and set up the files manually.
/etc/hosts reads:
127.0.0.1 localhost
10.0.0.01 one.network one
10.0.0.02 two.network two
[code]....
then the IPv6 stuff
/etc/network/interfaces reads:
auto lo
iface lo inet loopback
auto eth0
[code]...
Now I can access the internet from this machine, but when I attempt to ssh to another machine in the network I get the message "Port 22 network is unreachable" Checking with google I found that there should be some ssh config files. I have one ssh_config but no sshd_config. I don't know if this is relevant. Also "network" is not the name of my network. Changed for anonymity.

I installed openSUSE on one of my work system. The network port wasn't working when I was installing, but works fine now (checked in Windows). But for some reason, I am not able to configure the network. I used both Dynamic and Static IPs (both work fine in Windows) but still no go. I am using Yast Control Center for this purpose. I can't even ping the default gateway when I am using custom settings. When I use dynamic settings, it says Unreachable Network.

I have a problem with the Fedora 12 Network Manager - OpenVPN configuration. If I use the same configuration and manually start openvpn (as client) I get connected to the OpenVPN server and I can ping the network that I am accessing. With Network Manager - I get connected but when I try to ping is giving me "Destination host unreachable". The routing table looks similar except that when connecting with network manager is giving me on more route in table
Destination Gateway Genmask Flags Metric Ref Use Iface
xxx.xxx.xxx.xxx 192.168.0.1 255.255.255.255 UGH 0 0 0 wlan0

0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0
Where xxx.xxx.xxx.xxx is the IP of the OpenVPN server. When connecting "manually" I this routing table
Destination Gateway Genmask Flags Metric Ref Use Iface

0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0
What I do wrong in Network Manager? If I try to delete the route with xxx.xxx.xxx.xxx is disconnecting the vpn connection.

setup my static network connection Here are my details :
IP : 172.16.152.137
Subnet : 255.255.255.192
Gateway : 172.16.152.191
Primary DNS : 172.16.0.1
[code]....
but after this setup when i restart my network #service network restart while bringing up the eth0 the following message is displayed before [OK] - RTNETLINK answers : Invalid Argument now it seems either this setup is wrong or not sufficient to set up the connection, whenever i try to ping 172.16.0.1 it showing connect : Network is Unreachable

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'm having some problems with my wireless connection. I'm on Ubuntu 10.04, on a HP ProBook 4520s, with a RaLink RT3090 wireless network card. I installed the drivers (hopefully correctly), the wireless seems to work correctly, it scans and finds networks, but when I try to connect to one, it times out after some time, while still attempting to connect. I also have a wired connection that works correctly and without problems. Other computers that try to connect to said wireless network manage to do so without any problems, so this has left me a bit baffled, since, like I said, everything seems to be in order.
I'm a new Ubuntu user, so please tell me what other information I need to provide in order to easily and successfully facilitate troubleshooting this, because it is, as you can imagine, quite aggravating, having a laptop that needs to be connected to the internet through a cable.

I set up Samba using command line terminal, and my network does not work. I have Samba username and keyring passwords all set, then I go to gui system-config-samba, and my samba user profile password is incorrect. In the past, I have used a 10 letter password, however, every time I boot the computer, I have to go back in and re-enter the password.I wonder if samba is truncating the password because it only accepts an 8 character password? I have deleted the user, and added a new username, and it is still doing it.
If I go into the gui and re-enter the password, usually I can get the network back up with my windows machine. All of the parameters are correct, I use the network to transfer files from my Windows to my Fedora drive all of the time when it works.

I have one server with 4 network interfaces:
eth0: 192.168.0.0/24 - local lan A
eth1: 200.1.2.3 - internet link - default route
eth2: 192.168.10.0/24 - local lan B eth3: 192.168.20.0/24 - local lan C
Lan A - Default routing to eth0
Lan B - Default routing to eth2
Lan c - Default routing to another server but the workstations has static routing to this server too.
Everything is working fine on Opensuse 11.1 until I upgrade this sever to Opensuse 11.2 ( Reinstall, not update at all ). After upgrade to 11.2 the routing across local lan interfaces simply not work, if you try to ping lan-to-lan you got the message: Network unreachable, even with the IP Forward enable, but the default route is working fine trough the SNAT.
I've come back to Opensuse 11.1 and everything become normal, does anyone have an problem like this? Maybe a bug? PS: I do not try to disable the AppArmor, next weekend I will try Opensuse 11.2 without the AppArmor and post here anyway.

I'm using Ubuntu 11.04 and I've been running into a bizarre scenario. So when I open a terminal, I can type commands into it. Then I open a tab (by pressing Ctrl+Shift+T) and can type into it normally as well. But when I close the tab (going back to the original terminal), I suddenly can't type into that terminal -- no characters appear on its command line. It is not a severe issue since if I jump to another window (say Firefox), then come back to that terminal, I can suddenly type again. Also as far as I know this seems to be the only scenario to which this problem occurs. Has anyone ran into the same issue?

I'm using debian lenny.When I boot with kernel 2.6.36, ping always respond with Network is Unreachable. But when I boot with kernel 2.6.26 it works. I can't even ping the dafault router of 2.6.26 kernel when I am at 2.6.36. Also, system/administration/network does not show any connections while it shows something at the other kernel.

Every time I log in, a terminal appears on my screen. Previously, I attempted to embed a terminal as part of the desktop but I have deleted all the scripts and packages used, yet the terminal still appears. It is not an embedded terminal, but it does not have the panel at the top. It appears as a window on the lower panel of my screen. Is there anyway to stop this from appearing, so I can then attempt to start over with embedding a terminal in the desktop?
