OpenSUSE Network :: Nmblookup Resolves But Cannot Ping Netbios Names Or Ping FQDN
Feb 23, 2011This applies to my 2 opensuse PC's, my Windows PC is fine.I can ping a hostname, say "PC1" but I can not ping PC1.domain.local (even the host PC can not ping it's own FQDN). When I ping just the hostname the ping stats even list the FQDN.Onto the next issue, since all my PC's, have the domain prefix domain.local, my Synology can not. I can ping it's IP and that is it. I can resolve it's name with nmblookup just fine tho and that is what is killing me. How is this not resolving.Even weirder, I can browse to "Synology" in Network Servers under places on the slab.

Apr 18, 2011I am working on ubuntu 10.10 in a VM. I went ahead and did updated the system when prompted. That has disabled my wired network connection. I am not sure what is the reason. If it is a device driver or any network service. I guess device driver is not an issue as I can detect my network card from ubuntu.
Does any one know the solution?
Networking :: Lshw -C Network Shows USB Wifi Disabled?
Mar 3, 2010[Ubuntu 9.10]
I was using my usb Alfa AWUS036H-v5 usb wifi card, and then after I rebooted, it randomly stopped working.. did some searching on the site, one idea was to do
Code:
sudo lshw -C network
which I did, and it shows my internal wifi card (iwl3945) working fine, but says my wlan7 (Alfa usb) as:
network* Disabled
Also, in the upper right hand corner, the antenna is greyed out and says "Device Not Ready"
Ubuntu Networking :: Can't Ping Outside Of Network
Apr 30, 2011I can ping the router, but I cannot ping anything outside of the network. The ping just sits there and eventually times out, no error message. I cannot download updates and it is the only box inside the network having any issues accessing the internet. I am running 10.10 server. I can get a list of packages on the update server, but not download them, it appears to be in an incoming issue. I'm using a motorola Netopia router in bridge mode with a netgear SRXN3205 as a router. Again every other system can download fine. I have tried running on one nic, no help dhcp, static again does nothing. I can pulls host [URL].. and I get
[code]...
It may be worth noting that I set the box up at home on a dlink router and it worked fine, however I am confused why it is the only system on the network having these issues every other box can ping just fine.

Jan 28, 2009cannot ping internal network
I am a new user to Linux but in the last couple of months gained some Idea about it,I am trying to set up a small network in my office having 3 windows xp PCs, two fedora10 PCsI have an adsl router with 4-port hub connecting to the internet, one switch (say sw1) and one linux PC (say linux1) is connected directly to the router, the three win xp PCs are connected to switch sw1.all the above is working fine, I am able to get connected to Internet In all the systems, and able to network among all the above four.Now I want to make the linux1 as a proxy server for, hence I added another network card into it connected it to another switch sw2, which is connected to another linux pc (say linux2).
I have tried a hundred things, and googled an equal no. and finally posting it here.In order to reduce confusion I have disabled DHCP in all machines, and given static ips insteadNetworkManager was not happy about it, hence to fix my static IP i disabled NetworkManager ('chkconfig NetworkManager off')

Jul 23, 2010I have a weird problem that I can't find the answer for in the forums or docs. I can see the wireless network in Network Manager, but it is grayed-out and inaccessible. Other wireless networks are white and I can click on them and connect to them (or could if I knew the password).
My work computer, an IBM ThinkPad T43 running Win 7, connects.
My personal computer, a Dell Latitude C640 running Ubuntu 10.04, sees the network as grayed-out and therefore I have no option to connect to it.
I have tried the following:Checked for hardware drivers - the system says "No proprietary drivers are in use on this system"
Verified that the network security settings are the same on both my work and personal computers: WPA2-Personal
Why can I see the network but it is disabled/grayed-out?

Ubuntu Networking :: Cannot Ping/network To Host On 2nd Nic
Aug 11, 2010I have a somewhat complicated network setup that I am testing on an internal network. I have the following route setup:
PC Client (192.168.2.100) --> Router (192.168.2.1) --> DSLAM (on our internal network) --> PPPOE Server (192.168.9.1) on Linux Ubuntu 8.04 on interface card eth2.
On the same Linux Ubuntu Machine on interface card eth1 (static IP 192.168.5.100), I have an Asterisk SIP server plugged into it. SIP Server = 192.168.5.101 (static) I need the PC client (192.168.2.100) to register via SIP soft phone to register on the SIP server (192.168.5.101). From the PC client I can ping as far as the eth1 interface (192.168.5.100)...but cannot ping the SIP Server (.101).
From the SIP server (192.156.5.101)...I can ping 192.168.5.100, I can ping 169.254.5.228 (Eth2:avahi), but not sure what that is. I cannot ping the pppoe default gateway (192.168.9.1), which I think you cannot anyway. No firewalls are running. My IPtables I cleaned out totally. I think it might be as simple as a route add, but I really have no clue. Tried building a virtual bridge using brctl LINUX betweeh eth1 and eth2, but that made things worse (could not ping anything after that)
Route table:
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.9.100 * 255.255.255.255 UH 0 0 0 ppp0

View 1 Replies View RelatedFedora Networking :: SSID Broadcast Disabled - Cannot Connect To Wireless Network
May 6, 2010I have just installed FC12 on my machine - and gone Windows free for the first time ever. Now I do use various flavours of Linux on a daily basis but not from an installation/sys admin point of view so my questions here may seem a little basic but pleas eindulge me if you will!
Now, my network connection works perfectly well under the following scenarios.
1) FC12, wired to router
2) FC12, wireless, SSID broadcast enabled
3) Ubuntu (laptop), wireless, SSID broadcast DISABLED
The only scenario that does not work is FC12, wireless with SSID broadcast disabled.
I can only assume that it is an issue with my USB modem (a linksys WUSB54GS) since the same set-up works fine from my laptop running Ubuntu with an internal wireless card.
Now, I know from reading the forums that it's pretty easy to get around a disabled SSID broadcast but this is an itch I just have to scratch....what the hell is causing this problem?
nm-tool ouput is as follows:
I have tried using wpa_supplicant but I am not sure which driver I am using here - is it ndiswrapper per chance?
(Driver: rndis_wlan)
How I can connect once again to my wireless router with SSID broadcast turned off.
Fedora Networking :: Telnet Works Localhost But Not Network / Firewall Disabled
Jun 3, 2011I'm working on setting up access for our developer via Telnet, we are on a local network behind a physical firewall. I set up the standard Telnet service for Fedora15 and from localhost I can login via any user and root.... However I cannot login from another terminal on the LAN, even though I can ping and FTP to the fedora15 box. I added the firewall rules for telnet, that did not work, so I disabled the firewall, still cannot get a connection via port 25. I feel either port 25 is closed in another manor or the telnet is restricted to the localhost.
Also I cannot login to root to configure the Firewall Desktop GUI, only standard users, is this an issue? I also cannot login to the console as root even though I use the correct password.I can only su to root and sometimes it is a PITA. There must be some settings to clear these issues up...
Ubuntu Networking :: Network Disabled On Acer Aspire With BCM4312 802.11 B/g (Broadcom)
Aug 7, 2010I'm running Kubuntu and Windows on the same machine but when I swap over to Kubuntu I can't get the wireless to work. The lshw command returns network disabled but the machine can see that there is a wlan0 connection.
I've been trying to install the broadcom Linux driver from their site but the instructions fall apart at step 3: cd bnx...version/ ( directory just created by tar). I'm guessing this is because I don't have a Live CD (after almost a week of trying to burn a disc I just broke down and got Wubi) but that doesn't change the fact I have no idea what to do now or if this will even work.
If it makes any difference, the wired connection will also occasionally die mysteriously after about 30-60 minutes of use and refuse to re-activate but work fine when I switch over to Windows or just plug it into the router.
Ubuntu Networking :: Can't Ping Machines On Local Network
Jun 23, 2010So in an effort to increase the speed of my netbook, I removed Ubuntu and installed Lubuntu on it. When I tried to mount my samba share as I normally do, I noticed it wasn't able to connect - mount error(113): No route to host. Sensing something fishy, I attempted to ping the machine (both by name and by IP) - Destination Host Unreachable.The machine I'm trying to connect to is using Ubuntu 10.04 x64. I attempted to ping the other way and it was able to connect to the netbook just fine. When the netbook was using Ubuntu, it was connecting fine. My iptables check out ok, but here is the output of iptables -nvL:
Code:
Chain INPUT (policy ACCEPT 213 packets, 21635 bytes)
pkts bytes target prot opt in out source destination
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
[code]....
Does lubuntu have some funky firewall built in to it that I can't find? (I've Googled for information on a Lubuntu default firewall and can't find any)
Ubuntu Networking :: Can't Ping Localhost When Not Connected To Network
Jul 8, 2010I'm having trouble pinging localhost, specifically, pinging localhost when I'm not connected to a network. When I try it keeps telling me the operation is not permitted:
Code:
matt@mubuntu:~$ ping localhost
PING localhost (127.0.0.1) 56(84) bytes of data.
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
if I connect to the network, start pinging then disconnect it continues pinging. Google seems to think it could be something to do with my iptables setup:
Code:
matt@mubuntu:~$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
[code]....
When not connected to network
Code:
matt@mubuntu:~$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
But as far as I can tell there isn't anything in there which would stop me connecting to the localhost (I also can't connect to my local apache instance when offline)... (It's worth mentioning that a couple of weeks ago I had the pc setup to share it's internet connection with a laptop, ala this guide, however I've since disabled the iptables rules and disabled ip forwarding.)
Networking :: Can Ping But Can't Wget / Strange Network Behavior
Apr 28, 2011I have a small ARM machine running an Arch linux variant, PlugApps. It was set up and working fine at my home, with a standard networking setup -- cable modem and router. I could do pretty much anything I needed to access the net fine.This machine is a remote monitoring system for another location. I shipped it to that location and am now trying to get it set up using another set of hands on site. There it is on the network behind a dsl modem and a router. I forwarded ports from the dsl modem to the router and from the router to the ARM computer.
In both cases the ARM machine is/was configured to use dhcp.So here's the deal:I can ssh into the ARM machine just fine.I can ping hosts on the wan fine (eg: stanford.edu).BUT:wget fails for not being able to resolve a valid address (eg: http://checkip.dyndns.org)the PlugApps package management system (pacman) cannot resolve the repository address the openntp time sync isn't working On the new network, I am able to connect to another client windows PC which has the same associated network info (Bcast address, Mask, etc. - comparing windows "ipconfig" vs linux "ifconfig" outputs) but which can resolve addresses for web browsing, etc.What am I missing? If it can resolve addresses for pings, why can't it work for other address requests? If I can ssh interact with it, why can't it connect to the net for other purposes?

Networking :: Server Can't Ping Other Boxes On Private Network
Jul 27, 2011I run a server that is connected to several other boxes in a private network (192.168.0.0). I have had no problems previously, but upon a reinstall of Debian squeeze I have no connectivity to the private network: a ping of other addresses on that network fail. Ping and connection to outside world is fine. This box is configured similarly to another on this private network which connects successfully. I have quadruple-checked all my basic information. I post my ifconfig below of the malfunctioning device, then the ifconfig for equivalent nic on a box connected succesfully to the private network.
Questions:
1.Could it be a cable problem? (I don't see how since the cables have not been changed I do not believe since my reinstallation).
2. What about the difference in the last lines of eth1 below and eth2 of the successful box. Is it significant that the bad eth1 reads Memory:fc3a0000-fc3c0000
