Fedora Networking :: Cannot Ping By Hostname On 14

Jul 3, 2011

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.

My resolv.conf

Code:

Does anyone have anything I can try to get the name resolution working?

General :: Ubuntu 9.10 Networking Hostname / Can Ping The Linux Box Using Its Hostname From A WinXp. But Cannot Do The Reverse?

Jan 3, 2010

I have a network of 2 WinXP machines and one linux box. I have fiddled around with the settings as you do when learning. The network is working. The network neighbourhood on the WinXP machines recognise the linux box and vice versa, (the linux Places|Network recognises the 2 WinXP). I can Ping the linux box using its hostname from a WinXp. But I cannot do the reverse. I get an 'unknown host' response. I can ping the linux to itself using its hostname.

Networking :: FC13 Install Can Ping By Hostname - Ssh By Hostname Fails

Jul 29, 2010

I'm having an issue on two Fedora Core 13 machines where I can ping others by hostname, but the hostname resolution fails whenever I use ssh/scp/vnc/etc. I can still do these things by IP address, just not by hostname. RHEL5.3 machines on the same network with the same configuration do not seem to have this problem.

Here's the not-so-quick-and-dirty description of the situation:

I know that there is a virtual router at 192.168.31.1 and another at 192.168.30.1. I also know that there is another network (let's call it 90.90.90.0) and on that network lies a number of resources. By nature of this configuration, any machine on 90.90.90.0 can be accessed by any 192.168.x.x, but not the other way around. Beyond that is out of my hands and currently out of my scope of knowledge.

I have a dnsmasq server on 90.90.90.10 that operates as a secondary nameserver, another machine out of my sphere of influence is the primary nameserver (90.90.90.31).

The secondary nameserver on 90.90.90.10 holds the hostnames of our development machines. The problem is that in some cases, while I can ping by hostname all day long, services such as ssh, scp, vncviewer, etc all fail to resolve the hostname. In other cases I can do all of these things.

Every machine has an equivalent resolv.conf:

As an example, I will show the output of a handful of my development machines:

I also included columbia as a one-way test -- even though it cannot access 30.x or 31.x, they can access it:

columbia -- physical machine, Red Hat Enterprise 5.3, IP 192.168.100.200

Okay, so here are the various outputs. Remember, nibbler, discovery, and atlantis can ALL:
- Ping by IP address
- Ping by hostname
- ssh, scp, vnc, etc by IP addess

Additionally, the SERVFAIL reply from 90.90.90.31 is expected since my dnsmasq server is on the secondary server.

Note that the only machine that can both ping and ssh/scp/etc by hostname is nibbler, which also happens to be the only one of the three running RHEL5.3 instead of FC13. Other virtual and physical machines running on the 192.168.31.0 and 192.168.30.0 networks (all running RHEL5.3) work just like nibbler does. So the problem seems to only affect machines running FC13.

Final note: selinux is disabled, iptables is disabled, ip6tables is disabled.

Other than that, discovery is a brand-spanking-new install straight off of the FC13 DVD. atlantis has been around longer, but its just a file server so I haven't done anything too crazy to it.

Networking :: Fedora 14 Unable To Ping The Hostname From Any System.

Nov 24, 2010

I did a new install of Fedora 14. This is my first time using Linux seriously and I am trying to figure it all out.

I am able to ping my hostname of sinbad only from the linux system itself. On all my windows boxes, I am not able to ping it. I can only ping the IP address.

Here is /etc/hosts:

I disabled the firewall, disabled SELinux, and still not able to ping it.

Networking :: BIND9 SLOW Ping When Ping By Hostname

Feb 1, 2011

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:

/etc/resolv.conf:

Networking :: Cannot Ping Via Hostname Ubuntu 10.10 VM

Apr 6, 2011

I have a Windows 7 machine that I have an installation of Ubuntu 10.10 via VMware and am having an issue with pinging by hostname thorugh the VM. From the Windows 7 machine I can ping by name without any issue but not with the VM. I have the VM as bridged so it is pulling all the network stuff via DHCP including the correct DNS servers. I can ping all the DNS servers and host without any issue. I have verified my /etc/resolv.conf entries are all correct.

If I run nslookup via the VM it says:

I have also verified that AVAHI is running to cache the DNS stuff and still no success.

Networking :: Ping Debian On Hostname

Mar 31, 2010

How I can ping my debian computers on their hostname?

I have installed both samba and winbind and I have also changed the line in /etc/nsswitch.conf to:

Hosts: files wins dns

I have done the same thing on another linux box (ubuntu) just to see if that worked and it did - I could ping it on the hostname.

Also, I have trid to add the ip/hostname in /etc/hosts and even that didn't work.

The /etc/resolv.conf seems to be as it should.

In the /etc/hostname the hostname is updated.

I have tried to restart the samba service and the networking service and even the entire computer but none of it worked.

Ubuntu Networking :: XP Can Ping FreeNAS Hostname, Can't?

Jul 9, 2010

At work, I recently installed FreeNAS 0.7.4919 on a computer and set it up to be a samba server. Using a Windows XP Pro SP3 computer on the same subnet as the FreeNAS server, I can ping the FreeNAS server's hostname and it works just fine. However, using an Ubuntu 10.04 computer on the same subnet as the FreeNAS server, I am unable to ping the FreeNAS server's hostname. When I try, it says "ping: unknown host [the FreeNAS server's hostname]". I can ping its IP address just fine, though. Why is it that Windows XP Pro can ping the FreeNAS server's hostname but Ubuntu 10.04 can't?Here's the output of the ifconfig command on the Ubuntu 10.04 computer:

Code:
eth0 Link encap:Ethernet HWaddr 00:14:c2:cd:a6:39
inet addr:10.37.74.141 Bcast:10.37.75.255 Mask:255.255.252.0

Ubuntu Networking :: Can't Resolve Hostname For Ping - Ssh ?

Jan 7, 2011

I have a weird problem since yesterday that I can't solve. I can't ping / ssh my machine anymore using its hostname... says "unknown host", "network unreachable". I have no idea why - it used to work perfectly. I can still ping / ssh using the IP so it must be a problem of hostname not being resolved.

I have a dynamic IP (I'm at work...) but that doesn't seem to be the problem - network manager automatically adds a line in /etc/hosts with <mycurrentip> <hostname> (I checked, it's indeed the IP given by ifconfig and that I can use to ping/ssh).

2nd question: Another computer has a similar problem but slightly different: the hostname is resolved but points to a wrong IP (seen in ping or nslookup), different from what ifconfig returns. As a result, ping times out and ssh says "no route to host".

Ubuntu Networking :: Can't Ping Hostname In .local Domain

May 14, 2010

ever 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?

Ubuntu Networking :: Unable To Ping Windows 7 Box By Hostname?

I have a windows 7 desktop hardwired to my wireless router and a windows xp laptop connecting wirelessly on the same network. I am able to ping the windows 7 box by its ip address but unable to do so by its hostname. This is very inconvenient since I would like to set up a share by hostname (doesnt change) and not by ip (changes occasionally since its dhcp).

Ubuntu Networking :: Weird Can't Ping By Hostname, Nmblookup Works?

Sep 3, 2010

I can't ping by netbios name or fully qualified domain name, BUT nmblookup works just fine. I know it's a dns problem(s) I just don't know what or how to fix it. I'm very new to all of this(networking, domain administration, posting on forums etc) so I hope this is the right way to ask for help here. I've searched around the forums and the internet for a bit but I haven't found a solution to my problem yet.

here is some background on how the network is setup2 different domains sharing the same dhcp scope.

DC for DomainA is running windows 2003 std
DC for DomainB is running windows 2008 sbs
DC-A has ip of 192.168.1.249
DC-B has ip of 192.168.1.3
router is sonicwall (192.168.1.1)
DC-A is hosting both DHCP and DNS

there are 25 computers in DomainB and 1 computer (not in domain) with ubuntu 10.04 and Free Open Ghost running on it (dhcp off) all 25 computers can ping the fog server by name (and eachother) all 25 computers pxeboot to fog just fine

Networking :: Ubuntu Server Cant Ping Or Connect External / Can Resolve Hostname And Domain

Oct 15, 2009

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 setting up a NFS server and I would like to use my servers hostname when I do this. Why can I not ping my server by it's hostname? These are the 3 files I have changed...

Slackware :: Can't Ping Any Local Hostname

Feb 20, 2010

I've setup two slackware in a Dell Inspiron 640m e in Acer Aspire One D150.

In my router the domain is "home", the two slack use wicd (dhcpcd backend) to connect. I can go in internet.

The problem is that in my router panel I can see the hostname (so dhcpcd send the right one) but they can't ping other machine in the lan (windows 2000, nas or other linux box).

Now I can't use a fixed ip (i change several networks with different routers).

I think I miss something that can ask to my router the hostname.

Anyway I was able to ping Dell.local and Acer.local with Ubuntu karmic.

General :: Windows 7 Network : Can't Ping System Box Using Hostname / Fix It?

Sep 17, 2010

First off I should say that I am a total Linux and Networking Noob. I have used Windows all my life, but I am now trying to get into linux so I have set up an old PC with Fedora.

Currently I only have the Linux Box and a Windows 7 Box and they are both connected to my broadband router. I have set them up with static IP addresses in the router and they can both ping each other by IP address but not hostname. I would like to be able to use hostnames to access each box (e.g. for SSH access and File Sharing). My question is basically how can I do this, what are the options and which is recommended for a small home network?

So far I have been able to set up the linux box to be able to ping the Windows box by hostname by editing the hosts file. Is this the right thing to do? Should I just do this on the Windows box too?

Ubuntu Networking :: Hostname Changed But Email Still Using Old Hostname?

May 22, 2011

I have an ubuntu 10.04 server with hostname "abc.domain.com". However, due to migration, we had to change to hostname to something else, "xyz".

I have done changing /etc/hosts and /etc/hostname and run /etc/init.d/hostname start.

Checking the hostname and all shows it is now using hostsname of xyz. However, email sending out is still using old hostname. We have some scripts that will send out alerts like failed rsync or hdd space full to my email account. But I see the sender is still "root@abc.domain.com".

How do change that to xyz? I am using postfix. I have edited main.cf and restarted postfix but no go.

In windows, I go to view workgroup computers... only the windows systems. If I go to the F10 system with samba via the IP address it works fine, just can't get to it with a hostname.

I'm wanting a static IP of 192.168.1.22. And on the windows workgroup "workgroup".

I'm new to doing things with linux that are remotely difficult... and well, this has proven to be. I can't work out if this is a SMB problem, general networking...
