Pi Zero W is set up as AP & connected to my wifi. When connected, hostname resolves to 127.0.1.1, so I must use an IP address. Can it be fixed? [closed]

Question

Using the guide found at http://imti.co/post/145442415333/raspberry-pi-3-wifi-station-ap, I have a successfully working AP that is also connected to my home wifi, and passes thru internet -- I'm connected to the Pi right now, not my home wifi.

However, I can't utilize it's hostname to connect (ssh, nginx/web, etc), I must use the IP address.

I've tried restarting avahi daemon.

Pi has hostname altoid.

If I do host altoid from my local (connected) machine, I get 127.0.1.1.

Can I preserve this setup, and instead have it resolve to the IP I am using for ssh, etc?

EDIT: Adding file contents

/etc/hosts

127.0.0.1   localhost
::1     localhost ip6-localhost ip6-loopback
ff02::1     ip6-allnodes
ff02::2     ip6-allrouters

127.0.1.1   altoid

Answer 1

You may have been able to use the hostname, before enabling host AP mode, because you had the DHCPv4 client running that was registering withnyour LAN's default gateway that may also be running a DHCP and DNS proxy server. Now that you've disabled dhcpcd, your Pi doesn't get registered anymore with its name. A lot of platforms and applications only use DNS, but not mDNS (avahi), unless explicitly enabled.

Answer 2

When you troobleshoot your hostname, you must check some points :

• cat /etc/hostname should show your hostname.

• In /etc/samba/smb.conf file (if you use samba), netbios name should also point to your hostname.

You must also check that your hostname doen'nt contain invalid characters. Try to use one with only alphanumerics characters.

You may also try these commands, made for live hostname edition :

echo "Hostname">/etc/hostname
sudo hostname "MyHostname"
sudo /etc/init.d/networking restart
sudo systemctl daemon-reload
sudo /etc/init.d/samba restart
