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.

Ubuntu Networking :: Pinging Hostname Rather Than Hostname.local?

May 24, 2010

I'm trying to ping another Ubuntu computer on my local network. If I try doing,ping <hostname>then I get the messageping: unknown host <hostname>however, if I doping <hostname>.localthen I get a response back. I was wondering how I can change it so that I can ping without having to append .localI've installed winbind and modified my /etc/nsswitch.conf file but this has made no difference.

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.

if you do the command conky in terminal, it starts conky ofcourse, but it also shows output to that terminal so you can't do any other commands to that terminal, Is their an option like you can do with the '&' sign in other cases? If you do the '&' sign with conky it still gives output, also the conky -d command gives output...

Software :: Terminal Shows Unicode Squares For Control Characters

Dec 27, 2009

My terminal shows unicode squares (the little square with it's 2 byte unicode value inside it), whenever I press a control character while running a program (ex. cat or ping).See this example. Here I show the key's I pressed then turn off echoctl, and repeat the sequence. http://imagebin.ca/img/mXbutJ1.png

the 0003 is when I pressed Ctrl+C, and the 001A is when I pressed ctrl+z.Can anybody tell me why this is or how to turn it off. This is inside a gnome-terminal session, though I don't think it's gnome-terminal.If, inside this exact same bash session I open screen (by typing "screen"), it doesn't do this anymore, and ctrl+c/z/etc is completely quiet.

Ubuntu Installation :: Screen Shows A Terminal Username And Password To Access The Computer?

Oct 20, 2010

I'm having a hard time installing Ubuntu 10.10 (32bits). I load the CD and everything's ok throughout the installing procedure, but when the installation is over and it says it's gonna reboot it doesn't do it!

The screen resembles a terminal with a message like "the computer is going to reboot NOW!" but it could stay like that for hours. The keyboard is locked so I can't reboot by commands, and if I press CTRL+ALT+DEL it just reprints the same message. Therefore I'm forced to turn off my computer manually.

After that, the Ubuntu desktop doesn't load. The screen shows a terminal asking for my username and password to access the computer. No graphics at all.

Networking :: Registering Hostname In DNS?

Jul 16, 2010

I have a Fedora 13 desktop I have at work that I want to use to back up data off my laptop, also running Fedora 13. I can ping the hostname of the laptop from the desktop, but not the other way round. I don't think I did anything to have the laptop register its hostname with the DNS server. Since my company uses DHCP, I can't just edit the hosts file on the laptop. I want to be able to use the hostname when I mount the NFS shares for the backup. I also want to run the desktop headless so Remote Desktop needs to be able to find it. Is there a way to force the registration? If I ping the laptop's fully qualified hostname from itself, I get back the correct IP address. If I do the same thing on the desktop, it tells me it can't find its own hostname. I do have the domain name configured in the dns search path under System->Administration-Network

Fedora Networking :: Hostname Cannot Be Resolved

Running Fedora 11.

Did get a Kimsufi dedicated server through [URL] When I did get it the hostname resolve does not work.

I have never got any of this problems before so this is my first time playing with the network settings.

Nothing works! Lynx, wget, yum and so on. IT works if I do enter the hostname by its IP. But thats not working in the long way

Fedora Networking :: DSL Modem PC Name Is Not Hostname

Yet, when I look at the name assigned by the modem (using URL... in a web browser),I need the PC Name to be mertensia, because otherwise it will complicate how I ssh immensely.

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?

Ubuntu Networking :: SSH Not Working By IP But With Hostname

Jul 19, 2010

I just finished installing ubuntu server 9.10 - fairly new. I couldn't run SSH when I use IP address of the server. I've also setup DynDNS that returns responses when I ping. SSH works fine when I use the hostname of my server (leopard) but SSH doesn't work when I use IP.I was expecting IP for "eth0" something starting with 192.168.x.x as are my other computers running WIN on the same network.Any ideas why

1) Why am I not able to run SSH from IP assigned to server by DHCP. It works when I use machine hostname (leopard)
2) Why SSH isn't working from DynDNS web hostname when it responses back the ping command.

# The following lines are desirable for IPv6 capable hosts

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.
