How do I make/find a host name in Ubuntu (10.04) so someone outside my local network can connect via VNC (Remote Desktop). I went to System> Preferences> Remote Desktop, but then it says
"Your desktop is only reachable over the local network. Others can access your computer using the address 192.168.1.102 or geordie-desktop.local."
*Note, would this error be due to my ISP?
Normally each machine should have a host name such as [URL] Where should this HOSTNAME to be define normally? In ' /etc/sysconfig/network'? Else where?

ANything I have tried tells me that my computers hostname and fqdn is localhost.localdomain. The people on the service request seem to not believe me. Is there anyway that the computer hostname is hidden? This is what I have tried:

I'm writing a bash script that executes a few perl scripts. One of the perl scripts that I need to execute requires two arguments with it. The arguments are stored in a txt file, each line contains a hostname and its corresponding IP address separated by a ":" (colon), the txt file looks like this below:

I'm not sure if it's the best way to accomplish this but here it goes. In the bash file, let's call it getHosts.sh, I create an array and assign each line of the file to an element in that array. I then think I need to create a new array where I take the hostname (which is before the ":") separate it from its IP address and place the IP address on a new line just below the hostname (this way I can reference to it like $hostNames[$x] would be the hostname, and $hostNames[$x+1] would be its IP address). So the new array would now look like this below:

I have a server running centos 5 located in a datacenter. I am setting it up as a web server but haven't bothered to move the domain from my current registrar to the server as there are a lot of things I need to get done before that. I am having a problem where I couldn't install httpd. So i tried some of the basic fixes i knew as far as yum clean all and checking that my /etc/resolv.conf was ok. I have the two nameservers I am using listed there but I have no hostname set because I simply dont have the domain transferred or anything like that yet. Is that the reason I am having these issues. I installed the system with a network install fine about a month ago so im not sure why I am having problems now.When i try to ping centos.org I get an unknown host www.centos.org error. I tried changing the resolv.conf to have localhost as the hostname and I still have the same issues. I havent made any changes to anything that would potentially cause this.
My etc/resolv.conf looks like this:
search
nameserver 12.34.567.8
nameserver 12.34.566.8
Also it seems the problem may have got worse after yum clean-all because before that when I would try 'yum install httpd' it would show the files and filesizes and ask to install, when I would select yes It would give an error showing it could not find the fastestmirror. Now it doesn't give any file size or files or an option to approve the install. It just responds with an error saying it could not retrieve mirrorlist

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.

View 2 Replies View RelatedI 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'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.

We are running Ubuntu and I want to install an oldish drawing program (inkscape, although that's not relevant). The configure file for inkscape wants libpng and the configure file for libpng wants something called "zlib" which it checks for via the "-lz" option.
There appears to be something available online called zlib but it only makes "uncompress.so" I am getting absolutely nowhere trying to figure out whether I should just rename it as libz.a (seems wrong) or whether I even have the right package to make whatever libpng wants when it is asking for the "-lz" option.

Both show this error:

I'm have been tasked with created a base Ubuntu image that can be used for cloning to multiple machines. As this is a network environment, each hostname will obviously need to be unique. Rather than manually changing the hostname each time a new, cloned machine is rolled out, I was wondering if there is a way to use a variable in the hostname (i.e., use a variable to truncate the the last 6 digits of the MAC address to the end of the static hostname--or any other unique variable for that matter--so it would look like hostname00E6D4).

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 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...

(side note: man hosts says that the name is based off the hostname file, but that's clearly not the case here. It's being named off the /etc/hosts file. Why did we move away from /etc/hostname? It's SOO much easier)

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.
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

# The following lines are desirable for IPv6 capable hosts

What is the difference between /etc/hosts and /etc/hostname?
I think the /etc/hosts file stores all ip address associated with this computer, but what about /etc/hostname?
It sounds almost like the computer name, but what is it used for?
