http://askubuntu.com – When I try to edit my /etc/hostname file, using: sudo nano /etc/hostname (or any other editor) I get the following: Error writing /etc/hostname: Permission denied I then tried to: sudo chmod u+w ./hostname and got the error: chmod: changing permissions of `./hostname': Operation not permitted I get the same error trying to add write permissions to any use or group. This is what ls show: -rw-r--r-- 1 root root 22 2012-06-18 12:25 /etc/hostname Any idea why and what can I do about it? I'm running ubuntu 11.10 (HowTos)

Stories similar to no sudo permissions to /etc/hostname

I used hostname NEWHOSTNAME and set a new hostname. Then I restarted, and tried accessing the internet and nothing happened.

I tried to change my hostname according to this guide for Debian based system:

I edited /etc/hostname file run /etc/init.d/hostname start

Though there are errors. Always when I write a sudo command it tells me it can't recognize hostname. After I restarted the system, graphical environment wasn't working, startx command wasn't successful.

I've already tried changing the hostname by editing both:

/etc/hostname /etc/hosts

However when I try to use sudo it doesn't work. I have to restart the computer to make sudo work again.

Before the switch to systemd, I was able to ssh between my two machines via user@hostname but now I get a "could not resolve hostname" error and have to use the IP address instead.

I have several Amazon EC2 servers and I'm using Chef to manage the configuration. I'd like to set the hostname so that the default bash prompt is more helpful.

Right now after launching a new server it's just set as:

root@ip-10-123-123-123

Since I'm using Ubuntu 12 on these boxes I consulted the corresponding man page for hostname.

going step by step through the hostname bit of the startx script, it appears that, with a random hostname, `hostname -f` hangs indefinitely. Setting this simply to `hostname`lets X start up without a hiccup, but it does seem to interfere with sudo to some extent. I attempted to run netcfg (and I have the appropriate 'NOPASSWD' line in my sudoers file), and it asked me for my password.

I want to change the hostname of my computer. I can do it by editing (as root) the files /etc/hostname and /etc/hosts (unless I missed some other important place). But that's ugly. Is there a straightforward way to do it? (The hostname command only modifies your home directory.)

This would be a useful addition to System Settings.

I have a virtual server running Debian Squeeze. I can change the hostname by running the hostname new.host.name command or by editing /etc/hostname and then running /etc/init.d/hostname.sh, but after a reboot the hostname will be reset to the preconfigured hostname chosen by the server-hoster.

Error w/ SFTP connection 44 weeks 2 days ago

When trying to connect using sftp with key authentication, we are getting this error message.

$ sftp client@hostname.net#2222 Connecting to client@hostname.net#2222... ssh: client@hostname.net: Hostname and service name not provided or found Connection closed

Regarding the error message:

Hostname and service name not provided or found

This mainly has to do with DNS being not s
