I have a Ubuntu desktop PC and a Windows 7 laptop. They have network connection over a wifi router, which gives them local IP addresses. Both computers see each other when pinged by IP. The Ubuntu pc can ping the Windows machine by hostname, but the Windows laptop can't ping the Ubuntu PC.
It looks like this is a common problem with a well-known solution, as seen from this question: Access server by host name?, as well as some duplicates. However, the solution there is "install avahi". I have avahi running, and it does not help for me. I have no idea how to troubleshoot from here.
From the Ubuntu PC:
rumtscho@bradbury:~$ sudo service avahi-daemon restart [sudo] password for rumtscho: avahi-daemon start/running, process 3019
and then on the Windows laptop:
C:\Users\rumtscho>ping bradbury.local Ping-Anforderung konnte Host "bradbury" nicht finden. Überprüfen Sie den Namen, und versuchen Sie es erneut.
which means, roughly, "hostname not found".
I didn't find anything suspicious in avahi.conf. Here are the working lines of the file (everything else is commented out):
[server] use-ipv4=yes use-ipv6=yes [wide-area] enable-wide-area=yes [rlimits] rlimit-core=0 rlimit-data=4194304 rlimit-fsize=0 rlimit-nofile=768 rlimit-stack=4194304 rlimit-nproc=3
I tried both pinging
bradbury.local. I also tried uncommenting the line
publish-addresses=yes in the conf file. Both didn't work.
Any ideas what I am doing wrong? How can I find it out, what are my options?
Update I was told in chat that the Windows PC needs a "multicast DNS resolver", so I installed Bonjour. Now the error message is different:
Ping wird ausgeführt für bradbury.local [*IPv6 address edited out*] mit 32 Byt es Daten: Zielhost nicht erreichbar. Zielhost nicht erreichbar. Zielhost nicht erreichbar. Zielhost nicht erreichbar. Ping-Statistik für *IPv6 address edited out*: Pakete: Gesendet = 4, Empfangen = 0, Verloren = 4 <100% Verlust>,
"Zielhost nicht erreichbar" means "cannot reach target host", and there is 100% packet loss. So what should I do to make the Ubuntu PC reachable
