hostname issues after upgrading to systemd

view full story
linux-howto

https://bbs.archlinux.org – 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 set the hostname with hostnamectl and in /etc/hostname but curiously enough, my wireless router no longer displays the hostname under DHCP clients. kahlil88 https://bbs.archlinux.org/profile.php?id=39911 2013-01-15T06:03:57Z (HowTos)

Stories similar to hostname issues after upgrading to systemd

Since the demise of rc.conf I have been unable to find out how to set the system's domain name. I tried "hostnamectl set-hostname hostname.domain" but it just set the hostname to "hostnamedomain". I also tried setting it manually through the hostname utility but it broke GUI applications (could not connect to display error). No luck with google or tge wiki either.

@ghen, you are right about this.  But when I have seen this fudging things up, it usually ends up the hostname being the comment (in this case #hostname).  Do you think that it is actually setting it as a blank line?

Thank you very much, that was it!I tried removing /etc/hostname and it just went fine. However $HOSTNAME was not defined anymore after that so I tried to define it in /etc/rc.conf and that worked properly.

/etc/hostname   (or old style, HOSTNAME in rc.conf)

No connection to localhost 25 weeks 5 hours ago

Thanks, moetunes! My /etc/hostname has already been set to mybox .## /etc/hosts: static lookup table for host names##<ip-address>    <hostname.domain.org>    <hostname>127.0.0.1    localhost.localdomain    localhost# End of fileThis should be correct. Unfortunately, the problem is still there. Could /etc/hosts be innocent, after all?

Forwarding to a dynamic ip isn't possible, it must be fixed, and providing a static lease to the machine also "deletes" the hostname.

Propogating hostname to router 14 weeks 4 days ago

How do you propagate changes to your hostname from your Linux machine (I am using Linux Mint 13) to your router (I am using DG834Gv2)?

I changed the hostname in /etc/hostname and restarted. The router still resolves the old hostname to my IP address.

Thanks.

Change the Hostname in Linux 3 years 10 weeks ago

Just a short Tutorial today. It’s surprising how many people do not know this. To change the hostname under Linux, open a terminal window. Type the following code. sudo nano /etc/hosts and change the text to your new hostname. Changes will take effect on Restart.
