Ubuntu Servers :: No Ip Address Specified And Hostname Not Found Boot?
Oct 21, 2010
I have a ubuntu server 10.04 that will not boot. I saysno ip address specified and hostname not found refer to mount cifs blah blah blahmountall mount /directory/share [863] terminate with status 32I know its because I had a share mounted at boot but the server cannot mount the share for some reason. is there a way around this so I can boot the machine.I can ping the server. I just cant ssh to it. I need to get to a prompt some how so I can remove the mount from fstab.

I am using ubuntu 11.04.

ok so when i sudo apt-get update i get a bunch of crap that says no address associated with hostname
ive googled this and changed my /etc/hosts to all sorts of things and no luck apache wont even work now either. this server is for a few websites the company i work for hosts. currently i swaped it over to another windows based comp but we want it on ubuntu.
ive heard this is dns related? and that a FQDN is needed? if so im not sure how to re write my /hosts file but as of not it looks like this:
Code:
127.0.0.1localhost
63.119.120.135speed
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback

I have a machine running Slackware 13. Recently I had to modify network settings on it and now I cannot ssh into that box from my local LAN using machine's name. I can only ssh by using its IP address.I searched the forums, Google, but I cannot find the solution.

Right now my setup is as follows: I have an Asus Eeepc 900 running Netbook Remix named eeepc, and a media centre running 64-bit Ubuntu named media.When I try to ping or ssh into one machine from the other, for exampleCode:$ ping mediaI get an "unknown host name" error. However, pinging the device's IP address works. How do I get the computers to recognize each other's host names? Did I miss something in the setup?

New CentOS 5.4 system working fine. Sys admins came in and copied the hosts file from one of the servers down to my desktop and ever sincethen machine has been slow (progs take 10-20seconds to load). RunningGnome. Luckily I saved the old hosts file and copied it back and all is now well. But I'd like to understand why, particularly as I will need to change myhostname in the future.
As configured:
/etc/hosts (yes my hostname is "dummyName" that I will need to change later)
127.0.0.1 dummyName localhost.localdomain localhost

I can reach other hosts by means of their global addresses by either the IP address or hostname (that has the global address). What I want to (also) do is have a hostname that references the IPv6 link local IP address (an AAAA record in DNS, or just the fe80::<whatever> address in /etc/hosts) and use that host name in commands to access that host. The problem is, an interface ID is needed when making such a reference.
It sure looks like the programs just pass the host name string on to the resolver library, which does not understand the significance of the '%' even though it could find and see that the name preceding the '%' is consistent with that being an IPv6 link local address (e.g. the logic could have been "split at first % and see if preceeding name is found as a link local address and accept that if so, or ignore the split otherwise" ... but it isn't). Is there a different syntax for this ... or was it overlooked in the design of programming around IPv6?I want to be able to address a host by its link local address, while still using a mnemonic instead of having to type the IPv6 address.

I have installed a ubuntu 9.10 server to use mostly as a fileserver. When I installed the server I set it up as DHCP and later on I have changed the /etc/network/interfaces file, the /etc/hosts file and the /etc/hostname file. I have the ip 192.168.1.100 set on the server and I can ping and SSH this address. But I can not ping my server by it's hostname enighet. 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...
Code:
johan@enighet:~$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo

I've looked at several tutorials and since i'm a newb I can't figure them out. I'm trying to set my hostname on my LAMP 10.04. What files do I need to configure? (all IP's below are fake)
Here are the first lines from /etc/apache2/sites-available/default
Code:
<VirtualHost 111.111.111.111:80>

/etc/apache2/ports.conf has these lines after the comments

I have two computers.
Computer A = windows 7.
Computer B = Ubuntu Server 9.10
Computer B automatically receives an IP address from my router.
I can ping computer B from computer A using the IP address. I cannot ping computer B from computer A using its hostname.
My router did not show a hostname under it's active clients table. After some searching I found a threat where somebody suggested modifying /etc/dhcp3/dhclient.conf and adding 'send hostname "blahblah"' This allowed me to see the hostname in my router but I still cannot resolve it from my windows box.

I have a problem with server bcs of the machine name. I'm wondering how to change the server name to it's IP. bcs now it has name "chrochne". I've found hostname in /etc/host and in /etc/hostname. But I'm afraid of changing it in this files. I'm using webmin and virtualmin to admin the server so can I change the name somewhere in the GUI?

I saw in the tutorial "The Perfect Ubuntu 11.04 Server ISPConfig3" that it is possible to turn the internal ip into a hostname.
Example: 192.168.1.170 -> myserver.example.com
Example: 192.168.1.128 -> aserver.inet
However, when I edit my /etc/hosts file and after I echo the name to the /etc/hostname file, it still doesn't work. I am using Ubuntu Server 11.04 (Natty Narwal)

During install of 9.10 server, both ethernet adapters were found. One is built-in to the motherboard, the second is on a PCIe slot. Selected the on-board adapter for eth0 during install, set fixed IP on the web, connected, updated, etc. w/ no problems. The second adapter is for the LAN.BUT, on first and subsequent reboots after installation complete the second adapter is not detected at all, as if it were not even plugged into the PCI or the driver not loaded. This happens on either of two slots, with two different adapters, Intel or Netgear, both pretty recent, and both of which are detected and work in a different box. 'Ethtool eth1' says device not found.This is a fairly recent motherboard 3N78EM).Since the adapter was found during installation I'm assuming that the problem is not with not the board. I've built several server systems with two or three ethernet adapters and have never run into this situation.

I just built out an Ubuntu Server 10.04.
My problem is setting the hostname. I cloned the machine, then normally on the clone, I would change the /etc/hostname and /etc/hosts file.
However, when I do this, upon restart, I get the message, "init hostname main process (some process number) terminated with status 1"Then, when the machine finally boots, the hostname is set to (none). Literally has braces like: user@(none):
I've tried: sudo hostname machine_name but it says can't resolve hostname (none).
I've Google'd around a lot but can't get it. It may have something to do with 10.04? I have been using 9.04, 9.10 with no problems.
eric@(none):~$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface

I'm facing bit of a conundrum with my new server. It is essentially a distributed-virtual Plesk Virtuoso container with a rather simple LAMP setup (PHP5 etc) and virtual hosting. Running 10.04 LTS.
The issue is that on each reboot, the /etc/hosts and /etc/hostname files are reset with their original configs causing the virtual hosting to break, i.e. rather than hosting the vhosts correctly, it essentially routes all traffic to /var/www, or essentially 000-default ~ this beats the whole point of vhosting in the first place!
Is there any way to get around them being overwritten at boot? A very crude workaround would be to set a script to load at boot via init.d and have it rewrite both files to their correct configs - of course, I have no idea as to the point during boot at which they get replaced.

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.

We have an Ubuntu server running on Amazon EC2, hosting a website. We also have postfix, in order to send mail (receiving mail is done by another server which is specified in our MX records). My problem is that the internal hostname of the machine ("domU-xx-xx-xx-xx-xx-xx.compute-1.internal") appears in some "Received:" headers in the emails sent. Is that normal? It seems rather peculiar to me, and I'm thinking some e-mail systems might consider it spam because of this. GMail doesn't consider it spam, but not all systems are as smart as GMail

Im using bind9 as DNS server on my LAN, but it does not seem to translate its own hostname correctly for some reason. Other hosts is translated correctly, the problem only seems to apply to the DNS host itself. if i "ping <server_hostname>" from the server, it translates correctly. But if i "ping <server_hostname>" from the client it only says "unknown host" The client has the correct DNS-server assigned. How can i start troubleshooting this?

I have a home server running Ubuntu Server 10.10, it is running Samba for file sharing with a mix of Windows and Linux boxes in my house. My main problem is that the server is only accessible by IP or by using hostname.local, but it is not possible to connect to it by just typing the hostname. Further more, it is not being automatically discovered and listed by Windows or Linux clients.
What's really odd is that I also have an Ubuntu Desktop 10.10 install on a separate computer, and that computer is accessible using just the hostname and is automatically being discovered and listed by other computers.
What is missing on the server? What is responsible for resolving just hostname, avahi seems to only deal with hostname.local and that is working fine. I also compared the samba config of the desktop and server Ubuntu installs but wasn't able to find any setting that would be influencing this. Is there some package I'm missing on the server?

I am having a problem logging into my remote gentoo (2.6.23) linux machine using my hostname from my Windows XP machine using cygwin. I can login using my ip address, but not the hostname.
This works:
$ ssh me@xxx.xxx.xx.xxx
This does NOT work:
$ ssh me@my_hostname
ssh: connect to host my_hostname port 22: Connection refused
I have verified that my hostname is indeed "my_hostname" on my linux machine by using the "hostname" command.

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.

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.

I have installed Ubuntu on four machines at work and have been blown away. On my machine I have Apache setup for web development and other machines can "see" it using my IP address. I would like to have it so they can access by the name of my computer though. I have no local DNS server so I guess I need to hard code the relationship in each machine? Ideally I'd actually like to be able to use subdomains (which I use locally to avoid annoying .htaccess path problems). i.e. from another machine on the network to go to [URL].

I have my home network up and running. I can access my index file by the ip I gave to eth0 - 192.168.0.2
I put this same ip into etc/hosts:
192.168.0.2 localhost localhost.localdomain
One space separates the hostnames from the ip in /etc/hosts.
The hostname command returns: localhost.localdomain
I have /etc/resolv.conf configured the right way, so I can use my isp's DNS servers. I know this because yum works and I can ping anywhere by url. The next step is to learn to access the index file by url locally on my own network.
