I was using my ISP's DNS server. When I would ping something that doesn't exist, e.g. blahtest.com, it would reply anyway. When I tried to go to the site in a browser, it was some page like "I hope we can help you find what you're looking for". I thought that was ridiculous, so I changed to OpenDNS's DNS server.

If I type
Code:
$ ping [URL]
or even
Code:
$ ping google.com
should I receive a reply?
I run an centos server. From the console I can ping google.com and get a reply. But when I ping another address say xyz.com, the IP address is resolved (11.22.33.44) but there is no reply. In the same network in our office from my desktop I ping [URL] and there is a reply.I turned of the firewall but still the same problem.

View 2 Replies View Relatedever since upgrading from karmic to lucid, i cannot ping fqdn hosts in .local tlds. nslookup & dig work, but most other utilities fail (ping, traceroute, etc...). i know .local is an invalid tld, but apple seems to have made it a defacto standard on private networks, so i'd imagine somebody else has seen this issue before... is there a simple fix that doesn't require managing hosts file entries on a bunch of systems?

I have a debian server installed with a static ip. Now i am able to ping my ip, but when i try to configure a domain name with the nameserver as my ip, i am not able to ping the domain name
eg:
As the title suggest, I have downlaoded the latest copy of Ubuntu Server from the ubuntu website.Everything installed fine. DHCP configured ok as far as I can tell. I can ping other machines on my network (which are running Windows) and they can ping the Ubuntu machine and conenct to Apache which is running on it.If I try to ping google.com or any other domain, it gives the correct IP address but gives no response to any pings, dont telnet on port 80 (or any toher potr for that matter) on any machine on the internet. I checked the settings using ifconfig to see what DHCP had assigned, and they matched the windows machines configuration (other than the IP address obvisouly). I tried assigning a static IP, even reserving a particular IP for my NIC.
Whatever I do, i cant connect to any machine outside the network via IP or domain.I have searched everywhere and tried everything i can find on the net but still to no avail.The Windows machines are part of a domain called alcom-uk.local and run off of a Windows Small Business 2003 Server. Not sure if i need to manually setup Ubuntu to connect using a domain or 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.
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.
At the school i work in i have a server2k3 server that provides a domain to all the windows clients, aswell as a fedora server that acts as an imaging machine and webserver.
Im rather concious of the fact that if for any reason the Server2k3 server was to die there is no backup of active directory, or anything that can take its place whilst a replacement is found.
So is it possible to use a fedora machine with samba as a secondary domain controller? so it can be used as a login server, and has a copy of AD.
I am trying unsuccessfully to have a more permanent fix so I can receive emails from an invalid domain. The message is 'Sender address rejected: Domain not found' in the postfix mail logs. Fair enough, there may be an A record or MX record problem there, but there is nothing I can do about this with the Sender at present. Mail *will* come through from the invalid domain if I delete
Code:
reject_unknown_sender_domain
from the list at: smtpd_recipient_restrictions in /etc/postfix/main.cf (see coded area below for full list). I have added the Domain in question as an 'OK', both by name and by IP address, to: /etc/postfix/recipient_access, then used postmap to successfully create the database which appears as: recipient_access.db
ie recipient_access (not recipient_access.db) has contents: invalid-domain-name.com OK ; the space betw is a tab space 123.456.789.012OK ; the space betw is a tab space I suspect the failure is something to do with postmap and the recipient_access.db database file created by postmap, but just cannot work this out. Running: postconf -d indicates that the hash format is the default database format
As indicated below,
Code:
check_recipient_access hash:/etc/postfix/recipient_access is listed up front in smtpd_recipient_restrictions Postfix was restarted on all occassions Everything above was done as root and permissions on the .db files are the same as other files in /etc/postfix
From /etc/postfix/main.cf:
Code:
smtpd_sasl_auth_enable=yes
smtpd_helo_required = yes
disable_vrfy_command = yes

For clairification, I can ping. I have tried several IP addresses and 100% success rate. When I noticed the problem I was trying to run sudo apt-get update && apt-get upgrade After some time I noticed these error messages to start with
[Code]
I tried to ping the adddress security.ubuntu.com from my Windows machine to verify that I could connect and was surprised when I could. I then pinged the address 91.189.92.167 which is what my windows machine resolved the name as and it went though.
My thoughts on this are that when my Ubuntu Router came up, for some reason it did not incorporate the ISP's DHCP servers into the ip address it obtained. Sadly I know to view ALL IP infomation in windows via ipconfig /all command but I do not know what this is in the *nix world. need commands that I can use to check and troubleshoot this apparently DHCP issue so I Can start to update my server and expand on its services?
I have been logging into a server remotely and trying to set up a mailing list on it. The server is the newest version of ubuntu server: uname -a: Linux Themis 2.6.28-11-server #42-Ubuntu SMP Fri Apr 17 02:48:10 UTC 2009 i686 GNU/Linux.I noticed I could not download packages with apt-get or ping domain names, and I can't even ping 127.0.0.1.And do you think there is something wrong with the network card?

Is that the bind9 maybe?
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.
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:

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.

My ISP (Insight if you know them) says I had open ports. OK I did! Shame on me! I'll blame my $15.00 router but I know it's my fault. OK took care of that.But when I run Shields Up from grc.com it keeps telling me it can ping (IMCP) me. I tried to get the firewall to stop, or drop the ping and it seems to on my local network, I can't ping my my boxes locally and I can't even ping my router. But Shields Up keeps telling me it can ping meAny one know how I can see what's sending the ping, or I guess they call it the pong, back to echo the ping?

I am using a dhcp network. Problem is I can SSH/ping to my machine but can't SSH/ping to my machine from the remote one(In internal network of my lab). What to do? I understand this is very little information....but I dont know what to provide.
Have installed fedora 14 on a HyperV virtual machine, have added a Legacy network adapter in the Hyper-V settings for this virtual machine that fedore pics up as eth0. I'm pretty sure this card is able to pick up an IP address from a DHCP server on our network but I'm unable to ping any boxes from this fedora virtual machine or ping the fedora machine from another box on the network. I have tried to disable the firewall and SELinux incase it was that stopping the pinging each way but that didn't help.

I have 4 installations of Fedora 14 running on a Win 2008 R2 server in Hyper-V.
When I try to ping my desktop or the host server via the hostname from within any of the Fedora installations, the ping fails. I can ping by IP without issue. Also if I try to ping the VMs from my desktop it fails. I have an XP VM setup that I can ping without issue via hostname and IP.
All of the VMs can access the Internet without issue. I have disabled all firewalls on all systems with no luck. My desktop can ping the Hyper-V server without issue so it would appear that the problem lies with the Fedora installations.

I have a problem with my F11. I don't know how to add it to a domain !
