Ubuntu :: Sudo Broken After Hostname Change
Nov 2, 2010
I changed my hostname by running sudo gedit /etc/hostname and changing the word there. Then I discovered that hadn't done anything so I used sudo hostname newname. My hostname was changed then but I tried to run sudo gedit /some/thing/else.txt and it said:
Code:
sudo: unable to resolve host newname
No protocol specified
(gedit:5512): Gtk-WARNING **: cannot open display: :0.0 and it says the same with sudo or gksudo for any program that has a gui including synaptic. I can run vi but I have no idea how to use it. I think the problem lies in the lines in /etc/hosts which still say
[Code]....
with the problem being that it still says localhost and my local IP address are ubuntu instead of newname. So if you could tell me how to edit that with vi or some other command line program

In Ubuntu 9.10, sudo was working properly except it would not let me run speedy as sudo. I would get an error message, which I believe stated "No such file or directory. However, I could run the command as my regular user (being prompted it needed escalated privileges), and I could run the user as root. So I tried to "fix" it so that I could run it via the sudo command. My fix, in turn, ended up breaking sudo. I edited a file which contained the directories for PATH (I made a backup of said file), and that didn't work. It further broke sudo. So I attempted to restore the backup file, however, sudo was still just as broken.
Now, whenever I try to execute any command with sudo I get:
tim@linux-hp:~$ sudo -i
[sudo] password for tim:
env: -i: No such file or directory
tim@linux-hp:~$ sudo gedit
env: gedit: No such file or directory
tim@linux-hp:~$ sudo apt-get update
env: apt-get: No such file or directory
tim@linux-hp:~$ sudo nautilus
env: nautilus: No such file or directory
tim@linux-hp:~$ sudo update-manager
env: update-manager: No such file or directory
tim@linux-hp:~$ sudo speedy deploy
env: speedy: No such file or directory
I have since upgraded to Ubuntu 10.04 Alpha 3, with mild hopes that the upgrade would remedy my problem, but alas - it did not. How to get sudo back to a working condition?

I have a fairly old debian distribution running on the linux Kernel 2.6.18-4-686 and I did something silly which has broken multiple packages. I use the manual package installation command (sudo dpkg -i filename.deb) to install a single package (gcc base) however I did this using the latest version of the package which seems to have broken my GCC package completely and I am unable to compile c++ anymore.
When I now load the Synaptic Package Manager it tells me that I have 10 broken packages and when I use the fix feature it tells me I need to update other packages to fix the depencies (it selects almost every single package on my system to be removed at this point!).
I cant change the system too much because the software packages are set up specifically to run a certain application and I don't want to change anything incase I make it stop working!
So my question is this:
If I go to the synaptic Package Manager and uninstall the broken packages (they are all gcc related), will I be able to use the aptitude command to install GCC again? If so will it automatically install the version of GCC that will work with my system? or will it try and install the latest version and then update the rest of my system?

I broke sudo when I wrongly edited a file in /etc/sudoers.d in vi(did not use visudo :-().I read that I could fix the same by rebooting into the 'Recovery Mode' by selecting the same from the grub menu.
However I'd earlier disabled the showing of the grub menu by editing /etc/default/grub. As a result I can't seem to go into recovery mode to fix my broken sudo.

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 tried to change hostname through ssh.
Old hostname = server1
New hostname = server1.domain.local
I changed the hostname by editing the /etc/hostname file
Old:
/etc/hostname
server1
New:
/etc/hostname
server1.domain.local
Then I executed /etc/init.d/hostname.sh, and get as below, looks OK!
hostname -f
server1.domain.local
hostname
server1.domain.local
hostname -s
server1
The logs are still just showing server1.
Example:
tail -f /var/log/auth.log
Apr 15 13:30:01 server1 CRON[22783]: pam_unix(cron:session): session opened for user root by (uid=0)
Apr 15 13:30:02 server1 CRON[22783]: pam_unix(cron:session): session closed for user root
Do I really have to reboot, or is this normal behaviour that it does not show the full hostname?

I have changed my hostname to - ns1.searchdns.net by
1) editing the files /etc/sysconfig/network
2) then run the command - echo "ns1.searchdns.net" > /proc/sys/kernel/hostname
3) then restarted the service /etc/init.d/network restart
I run the command hostname and it returns ns1.searchdns.net. But I am also supposed to modify the /etc/hosts file. I am not sure about this. The content looks like this at the moment
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.0.20 abc.com
What should my host file look like now? I am not sure if I should also modify the second line or delete it etc.

Yesterday, while trying on establishing mobile broadband, my hostname changed, and I can't make it yet. My /etc/hosts is
1 127.0.0.1 pc-194-101.fysik.uu.se localhost.localdomain localhost
2 127.0.0.1 pc-194-101.fysik.uu.se roddur
3 ::1 localhost.localdomain roddur
The second line I edited but after a reboot it inserted the first line all automatically and my /etc/sysconfig/network is
1 NETWORKING=yes
2 HOSTNAME=roddur
What I have to do if I have to change my hostname to "roddur"?

How do you change the hostname in SLES11? I have normally used the /etc/hostname file and rebooted the server in other distros. I only notice the way to change it is in yast2 -> network devices -> network settings -> Hostnames. I am looking for where it is stored because I want to write a script to update it (apart of a server deployment process).

I've a little trouble: I reinstalled on my notebook OpenSUSE 11.3 yesterday and I'm unable to change the hostname. I modified it, but when I type on terminal
Code:
uname -a
it doesn't give the right answer but returns
Code:
host
I don't know where I wrong because I did this action many times with Opensuse 11.1 and 11.3 without any problem.

When browsing in WinXP Windows Explorer to view an OpenSUSE computer, the displayed name is:
Samba 3.5.4-5.3.1-2489-SUSE-SL11.3 (*hostname*)
Other Windows computers display as:
[computer description]([hostname])
How can I change the "computer description" within OpenSUSE?

I'm trying to write a script to change the hostname of the computer at the first boot. The reason why I need this script is because I manage a number of training computer and I use Ghost to re-image it every 2 months. The script will read the mac address and the hostname from a csv file and compare it with the mac address on the current machine. I have stuck and don't know what is wrong as I'm new with script.
csv format:
Code:
00:11:22:33:44:55 host01
00:11:22:33:44:56 host02
script:
Code:
#!/bin/bash
# Description
# Change HOSTNAME for each machine from CSV file
#
# CSV File Format
# Each line contains two columns - mac address & hostname
# Description End .....

My colleague changed the hostname using "system-config-network", but now I want to change it using any how (either system-config-network or /etc/sysconfig/network). Even I changed it from /etc/sysconfig/network. But when I reboot the system its getting old hostname. Is there some other place to change hostname?

I built the system with one name and now want to change it.I do the usual things. change the /etc/hosts file change the hostname with the command hostname newname changed /etc/sysconfig/network and then mail stops working. Put it back to the old name and it works fine.So I am guessing I am missing something in the configuration for sendmail. I checked the sendmail.cf file under /etc/mail and no reference back to the hostname was found.I also tried the GUI on the console to change the hostbname.

first time user of F14 here. Used PCLinuxOS so far. Installed F14 fine , got samba up, set the hostname of the box to fedora.linux BUT when I connect to my wireless router (Belkin) the hostname shown in the routers DHCP client list is different:
Router shows:
IP Address-----Host Name-----------------MAC Address
192.168.2.4----ralf-FK790AA-ABA-m9---00:22:5F:17:dE:98
In terminal it shows
[dagaz@fedora ~]$ hostname
fedora.linux
[dagaz@fedora ~]$
When I search the forum or google, I end up with hostsfile or samba howtos. Those settings all show the right name : fedora.linux Why does the router show ralf-FK7 etc..? and where can I change it?

I installed openSUSE on my notebook with an usb drive using openSUSE 11.4 KDE LIVE iso. The installation process set the name to "linux-ygrl" which I don't really like. (I probably just missed the setting during the installation.). I tried to change it through YaST -> Network -> Hostnames and I set everything where needed to the new name and restarted but the changed weren't applied. I searched the web and found out about the /etc/HOSTNAME file which still contains "linux-ygrl". Now I could change it manually but I was wondering if there is a GUI for it? (I mean, openSUSE has for alsmost everything a GUI.

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.

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'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.

My first post. I've been using Ubuntu Server edition (Hardy) happily for some time now.
I use sudo regularly during configuration of new services. It always works/authorises within seconds, however, it recently became very slow, to the point of being nearly unusable.
In /var/log/auth.log I noticed a regular working pattern like this code...
