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 24, 2010I'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.

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.
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.

General :: Explanation Of Command To Uppercase First Letter Of Filename
Jun 10, 2010I'm trying to learn to rename files with the command line, and after browsing around a lot of pages I finally found a command that uppercases the first letter of a file, but the problem is that I want to understand the meaning of each command. The command is:
for i in *; do new=`echo "$i" | sed -e 's/^./U&/'`; mv "$i" "$new";done
I understand the 'for' kinda... but not the 'echo' or '`' and especially the sed command.

Server :: Uppercase Usernames In / Etc / Sudoers Triggers Warnings
Jan 6, 2010We're syncing users from Active Directory over to our linux LDAP server (Red Hat Directory Server). The user names on the AD side are all written in uppcase letters, which is the company policy.The uppername usernames causes problems when setting up /etc/sudoers, since uppercase words are interpreted as aliases. For example, if I add user KENNETH to a User_Alias (i.e. something like "User_Alias ADMINS = KENNETH"), I will get a warning from visudo which expects KENNETH to be an alias and thus not a username. Despite the warning, sudo does seem to work correctly. But is there a way to tell visudo or sudo that usernames are uppercase, and should not trigger a warning? Or are there other ways to go about this sort of thing?

Sep 21, 2010I'm trying to convert all file extensions for files in many sub-directories from uppercase to lowercase. I have two problems, how to list the absolute path to the files recursively over many sub-directories for which I so far have this:-
Code:
find ~/Photos -print which would be fine, except it gives the directories on their own when it finds them rather than just the files with absolute paths. I couldn't find a switch for the "ls" command to do this, so I had to improvise with "find". and once I get grab each absolute file name, to just change the file extension rather than the entire file, which is what I have at the moment.

View 5 Replies View RelatedUbuntu :: Using Variables In Hostname?
Aug 27, 2010I'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).

Ubuntu Servers :: Can't Ping By Its Hostname
Jan 3, 2010I 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

Ubuntu :: Hostname Is Getting Set To 'localhost' On Startup?
Feb 22, 2010Everytime I turn on the computer, the hostname is getting changed back to localhost.
Code:
cat /etc/hosts
127.0.0.1najilelocalhost
# The Following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
[Code]....
(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)
These computers (It's more then one) were all installed with the minimal Ubuntu disk and then installed basic software such as xorg, nautilus, gdm, and openoffice.
Ubuntu Networking :: SSH Not Working By IP But With Hostname
Jul 19, 2010I 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.
