Ubuntu Servers :: Unable To Resolve Host / Hostname Is Set To (none)?
May 25, 2010I 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.

General :: Ubuntu 9.10 Networking Hostname / Can Ping The Linux Box Using Its Hostname From A WinXp. But Cannot Do The Reverse?
Jan 3, 2010I 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.

May 11, 2010I'm trying to make an SSH script for my place of employment. This script, I want to go out to the server hostnames we have specified (in another file) and change a users account password. We use Kerberized telnet, so if telnet root hostname fails, I want it to use ssh username hostname and use the old password (specified). If both fail, I want it to ask the user what the port should be and input the port in the ssh command.
But I'm having a issue having it try telnet root hostname and if it fails then, try to ssh in, I have no clue how to have it proceed. Is it an if statement? Here's the telnet failed message: telnet: Unable to connect to remote host: Connection refused

Networking :: FC13 Install Can Ping By Hostname - Ssh By Hostname Fails
Jul 29, 2010I'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.

View 2 Replies View RelatedUbuntu Networking :: Hostname Changed But Email Still Using Old Hostname?
May 22, 2011I 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.
General :: Transfer Large Number Of Files Host To Host
Oct 20, 2010I have two servers, one has an empty / and the other has a subdirectory with a large number (4 gig) with many, many files. I need a way to transfer the files en masse from the server with the large number of files to the one that is essentially blank.I don't have space on the used host to simply gzip all the files. I've googled this and see that there may be some combination of tar and/or gzip that will let me do this with some sort of redirection.
I really need and example line of how this can be accomplished. If my explanation seems rather sparse, I can supply more details.

May 5, 2010I tried posting this before and I'm not sure what happened but I don't think it worked, so if it did please forgive the double post.am very very new to centOS and linux in general. I just want to setup a test web server that more closely mirrors our actual web server that is hosted by rackspace. I've installed centOS and tried to setup Apache, PHP and MySQL from a guide on the web using Yum. When I go to localhost in the web browser I'm able to see the default apache page. However when I create a php page it's just blank.When I look at the apache error logs I get this: PHP Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0
I've been searching alot on the internet and I know the issue is permission related, but I don't know how to fix it. I've seen some forum posts that say you need to use the chmod 775 command on the /var/www/html folder.Currently when I do ls -l /var/www/html it returns
-rw------- 1 root root 19 May 5 13:16 index.php
-rw------- 1 root root 19 May 5 13:15 index.php~
I'm sure that this isn't correct but like I said I don't know much about how to set permissions or who the owner needs to be. I've done alot of searching and seen similar posts, but no one seems to explain it clearly.
