Ubuntu Networking :: Ping Fail But Can Browse?
Dec 23, 2010I have a DSL connection, DHCP, able to browse and no problem with that.
But I can't ping websites or their ip address. Should I be worried? I'm using Maverick through Wubi.

recently I got new wireless card, att usb Quicksilver(based/produce by Option?), for att.Regular gnome network manager freezes the computer when I am plugging it it therefore I installed the one from wicd.net.Also, I am using HSOConnect (to connect by to G3 network), and sometimes I connect to regular wireless g connection through router.
Under both cases I can ping the website by IP and can access the website by ip (ex. google) but can not ping or browse by name.As a side note... I can use and access Skype fine under g3 network and normal wireless.I tried browsing and finding other solutions in past few days but ended up breaking everything and reinstalling to get back to the point I am at now.I am working on the road, so not being to broswse is rather crippling to me.... also I can access internet normally only from home from different computer now.
I have a edimax USB wireless and as soon as I plugged it in it worked i.e., it is able to connect to a wireless.

I'm using FC10 on my box at work. It is behind an anthenticated proxy for internet connection. In Gnome, I configured the Network Proxy through the GUI, as my browsers too.
So I can browse internet pages, install packages thru Add/Remove Software GUI, but I cant do it in the command line, using yum install, for example. Then trying to figure it out, I saw that it cant reach the package mirrors. It isnt a DNS problem, I set the /etc/resolv.conf correctly, as the host command works correclty. I can ping the local pcs on the network too. Firewall is disabled. Below some simple tests:
[rtovo@davinci ~]$ ping mirrors.fedoraproject.org
connect: Network is unreachable
[rtovo@davinci ~]$ host mirrors.fedoraproject.org
mirrors.fedoraproject.org is an alias for wildcard.fedoraproject.org.

I've got a weird problem on my fedora 12.
My computer is running behind an ISP box, Firewall shut off, SELinux disabled.
I've a local IP address : 192.168.0.2 dynamically given by the ISP through DHCP
I've got bind installed. I've defined a domain (let's call it mydomain.com) in the /etc/named.conf this way :
Code:
//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
[Code].....
Finally, the named service is running.
Here is the trouble : I can ping my domain, but when I try to browse to this domain in my browser, the connection is rejected !
Background: In attempting to move from XP to linux, I have a F14 live USB stick -- can boot Dell M6400, see the internal drive and USB sticks. Wired ethernet network is seen only if ethernet cable is plugged in before booting. Then, I can ping sites by name (yahoo.com, google.com) -- however, FireFox does not load any web-page over the internet -- it does not put up an error message either, it just keeps waiting (it is in on-line mode).Info on the system

I have a small Dell PowerEdge 1650 server with Fedora 12 loaded. We can access the internet, (Google, our home page, Etc.) but can not ping any local or outside IP addressed. Our internal computers can ping each other but not the server. No, it is not the server firewall because we also disabled it and still the same results.

View 1 Replies View RelatedUbuntu 11.04, wireless adapter BCM4312.The connection works for a while, for a random length of time from a few minutes to a few hours, then stops working. The laptop says it's connected, and the router says it's connected, but the browser can't find any Web pages, it can't find the router, and there is no response to pings from the router or any other device on the local network or on the Internet. "Host unreachable." When I try to ping to the laptop from another one, it times out.If I shut down the computer and try again a few hours later, it works fine again for a while, then after a while it stops working again.
In case it's relevant, sometimes when I restart networking from the command line, it says "ignoring unknown interface eth1=eth1," even though ifconfig -a lists eth1 as up with an ip address. eth1 is the wireless adapter. Another laptop with Ubuntu 11.04 connects to the same router with no problems.Using a fixed IP address doesn't change anything.
I've just done a clean install of F14.have a wired ethernet connection (no wifi).Initially, I was able to browse the web with Konqueror... but after doing a big package update, and installing Firefox, I can no longer browse any website (Unknown host errors).The strange thing about this is that I can ping successfully via hostname
View 2 Replies View RelatedI can ping IP addresses of sites, say 209.85.229.99 (google.com), but I cannot ping google.com, nor browse it. Same thing for every alphabetic address and hence in practice I have no internet on my laptop. In windows, I'd just flush DNS but I don't know what to do in Ubuntu. I am using WICD.
View 9 Replies View RelatedI am using an virtual machine. where I need to ping from one machine to another. earlier I was able to ping. But after going to google.com once, I cannot ping back to this machine.
But if I gave ping -I eth1 <IP> then I can ping.
I cannot install any package, so tell me solution which includes not installing any package.
I have 4 centos5 apache webservers all on the same network, recently, 2 of the webservers have stopped being able to ping or browse one particular website where feeds are obtained from this site. I have checked and firewall and selinux settings are disabled. The two webservers are able to ping and browse other sites. Dns settings are the same for all 4 servers. traceroute for working and not working webservers are the same.

I have two machines on this network, one running Ubuntu and the other running Fedora.
When I'm using the Wireless network on the Ubuntu machine, I cannot ping the Fedora machine. Everything else works. I can browse the net fine.
If I switch over to the Wired Network then I can ping the other machine.
I don't understand why ping doesn't work only over the Wireless. I can ping the router so I'm guessing it's getting blocked by the router but I didn't block ICMP traffic.
I tried asking on IRC and they ran out of ideas too to find out where the problem is.
Ive got a problem on my server ....installed Debian 5 , Webmin and than syscp settung up syscp ready ....
I try to ping "localhost" ansver ping: unknown host
I try to ping "localhost." there is a host with IP 127.0.0.1
I need it to change it in "localhost"
Is that the bind9 maybe?
I just installed my first EVER bind DNS server. I am running bind9 on Ubuntu 10.04. Everything seems to be working great except one thing: If I ping a host that I have set up in bind by its HOSTNAME the pings take 5-6 seconds to reply/print to the screen between each echo response. If I ping by the host's IP address, they echo back very quickly.
I have read that IPv6 can cause this, but I have disabled it in /etc/sysctl.conf and the problem still exists.
I know everyone says this can't be a DNS issue, but this never was an issue with dnsmasq (which i was using prior), and it doesn't make sense that the ping are ONLY slow when pinging by hostname and not IP.
Configs below:
Ping by hostname - there is a 5-6 second delay between each one of the responses:
Code:
Ping by IP - the responses come VERY quickly one after the other:
Code:

So, I have an Virtual Machine running CentOS 5.4. It sits behind a hardware firewall which also does NAT'ing. I've set up plenty of these, so I know for sure the firewall and NAT rules are set up correctly. From the host, I can ping anything in my subnet and the gateway. But I can't ping anything else beyond the gateway. I can perform DNS queries and when I try to ping, it finds the appropriate IP address.But from the outside, I can ping the PUBLIC address (It's a 1 public to 1 private address NAT, not 1 public to multiple private). I've tried it with IPTABLES on and off, with no change.

Do I have to change some settings in router?. Or is it firewall issue on those two machines?. Both of these boxes are connected by cable. Symbol of the router: TL-WR340G.
I have connected xp and fedora through crossover cable . xp has ip address 192.168.0.1/24 (manually assigned) fedora has 192.168.0.2/24 with default route equal to 192.168.0.1
I can ping fedora from xp computer but i can't able to ping xp from fedora computer.
I have manully edit the /etc/sysconfig/network-scripts/ifcfg-eth0 file with correct subnet mask and ip address because when i tried to give ip address manully in network manager the subnetmask is replaced with gateway address don't know why.
Now i want to share internet through crossover cable . xp is connected to internet through wireless usb adapeter.

brand new install of 10.4 server and I'm having a strange issue. I cannot browse to any website by it's domain name, but I can connect via IP address.
I've been googling around and did the following:
added nameservers to /etc/resolv.conf based on an nslookup from my windows box:
nameserver 71.250.0.12
nameserver 68.237.161.12
I commented out the hosts line in /etc/nsswitch.conf per another site and changed it to: hosts: files dns
I can see other computers on my local network via IP and I can browse to the server's default apache page by it's hostname, so I'm assuming it's something about the server's dns resolution, but I'm not sure of my next step.
I have Ubuntu 10.10 at work and I've installed a Windows XP virtual box machine under it, that is joind to our Active Directory domain(but Ubuntu is/will not joined). I've set up VPN on XP box and I can connect to it from Ubuntu. I want to browse network shares(that use AD for permissions) and domain sites(like sharepoint) from Ubuntu. But even after connecting to VPN when I can't browse network shares, and nautilus asks for domain user/pass and tries to open share with no success. What extra steps is needed to browse my corporate network from Ubuntu via VPN?
