Ubuntu :: Can Ping IP Addresses Of Sites But Cannot Browse
Feb 16, 2010
I 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.
The problem that I have been struggling with is while connecting to VPN server, I can't connect to other sites.
I am on 11.04, but this have been happening on 10.10 as well.
On Win7, I was able to browse the VPN and the other sites at the same time without any issue.
I also tried by checking ON the "Use this connection only for resources on its network" option (under IPv4 settings tab) but doing that is allowing me to browse all sites except the VPN site. The method that I am using is "Automatic (VPN)".
A few days ago my wireless windows vista computer internet was running slow so i reset the modem. Then I went on the internet on my ubuntu machine machine and went to www.google.com and couldn't connect to the server so i tried linuxquestions and i couldn't connect but i could ping sites. My wired and wireless windows computers worked fine. So I called Comcast (my ISP) and said it was a router issue. So I looked online and it said to disable IPv6 on firefox so I did but that still didn't work.
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'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
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.
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
uname -a Code: Linux localhost.localdomain 2.6.35.6-45.fc14.x86_64 #1 SMP Mon Oct 18 23:57:44 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux [code]...
I have a box at home that I've installed CentOS 5 on to. I'm new to Linux, so before connecting it up to the router I wanted to try and understand the network settings, so I connected it directly to my other PC with an RJ45 cable. From Windows 7 I can ping all known static IP addresses, but from Linux I can only ping the Linux addresses, not the Windows 7 one. Below are the TCP/IP IPv4 settings, all IPv6 settings are set to auto-assign.
Windows box (uses wireless connection for the router): Local Ethernet Adapter IP Address: 30.10.0.1 Subnet: 255.255.0.0 No gateway, primary/secondary DNS.
Linux box: Three adapters: Two onboard LAN, both configured to: IP Address: 30.10.0.2 / 30.10.0.3 Subnet: 255.255.0.0 Gateway: 30.10.0.1 No primary/secondary DNS.
One LinkSys PCI card: IP Address: 20.10.0.1 Subnet: 255.255.255.0 Gateway: 192.168.1.1 (my router) Primary/Secondary DNS: my ISPs details.
The idea was to connect the box directly to the router (with RJ45) and to be able to remote login from my main PC to this one. This box is to be my home server, which I was going to put virtual machines on to for things like my development work and such.
I have strange issue on Centos 5.5 server.I have static IP address (192.168.58.2) on eth1 card and can't get ping response from some sites.PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
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.
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'm pinging a certain website and what happens is that each time the ping process freezes for an unknown reason ca. 10-15 sec then it starts to ping. Note that only this particular domain causes this hanging and Ctrl-c seems to have no effect at all! The domain is niteco. So far I've tried several independent linux systems all with the same result however other non-linux systems ping normally.
In my Fedora13 machine, while in mobile broadband, i can ping and skype outside, but cannot browse/yum etc. Few output that may be of relevence are here:
$ netstat -s IP: 149468 total packets received 6 with invalid headers 16174 with invalid addresses 0 forwarded 0 incoming packets discarded 118821 incoming packets delivered 101331 requests sent out 124 outgoing packets dropped 866 dropped because of missing route .....
new installation of fedora 14 intel pro/wireless 29251abgeverything ppears to be workingbut ping doesn't workand firefox doesn't workping resolves names but doesn't ping??
Do any one knows how to ping global inet6 addresses assigned between two systems. I assigned inet6 address through "ip addr add 2001::4 dev eth0" and similarly 2001::5 in another machine and tried to ping 2001::5 from 2001::4, but it is showing,
sait87@static-host:~$ ping6 2001::5 connect: Network is unreachable
I know this is not a win-doze forum but i always ask my questions here so here goes.I am having what appears to be a DNS problem on a friends laptop. He is running windows XP. I CAN connect to networks and even ping websites but i CANNOT browse in Internet Explorer or FIrefox.
Ubuntu 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 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.
In the past week or so I've noticed some weird network behaviour. I find accessing some sites such as Amazon, Paypal, and Bigstockphoto really slow. Sometimes the page will not load at all. Other sites are fine. The problem sites are not a problem for others on my LAN at home. When I try to open the problem sites, I can see in Firestarter blocked connections coming from 2.1(8/9).xxx.xxx on various ports such as 36007. This only happens for the problem sites. I attached a typical output from firestarter.
This happens with Firfeox or Chrome. Using Ubuntu 10.10
I dual boot XP and FC14 and have 2 routers. I can connect and ping one of these routers when I'm in FC and I have an IP address I just can't load any websites. When I connect to the other router (my main router) it works fine. When I boot into XP and connect to the problem router I can load pages fine. It's only when I'm on FC14 and connect to the problem router that I can't load pages even though I have an IP and can ping around.
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.
This 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.
