I'm new to BBB, and my linux experience is limited. But I kind of thought changing the /etc/hostname file would be all I would need to do to connect to it by name.

I set the hostname file to LorenzBBB1, but cant ping LorenzBBB1 from the windows PC (or ping the windowsPC by name from the BBB). But can by IP address. (the BBB can also ping google.com just fine).

From a Linux PC (unbuntu) I'm able to ping LorenzBBB1.local (but only with the .local). And the BBB can only connect to the linux with the name.local as well.

All the widnows PCs on the network can ping each other by hostname no problem.

For this I conclude the mDNS is working, but for some reason the DHCP server is not updating the DNS records for the BBB?

If I ping LorenzBBB1.local from the BBB it works, but LorenzBB1 it doesn't. Only the mDNS seems to work.

This is more of a how to get linux to play nice with domain names than a BBB question, but anyway I'm out of ideas on what to check.

I guess it could be an issues with the company router, but what configuration on a router could make lan dns not work for linux, but work fine on widnows?

Useful question. For newbies like my self, modifying hostname requires rebooting or systemctl restart avahi-daemon so that ping LorenzBBB1.local works from Linux (Ubunto in my case). Still doesn't work from Windows... –  Mark Lakata Jan 22 at 21:31

The answer for me at least was you need NetBIOS

The easiest way to get this seems to be install samba.

opkg install samba

On reboot it then just started working.

If anyone knows of or finds a lighter weight package than samba (all I need is the netBIOS) I'd be really interested in hearing about it.

After adding the hostname you also need to update your dhcp client configuration file

Try adding the following steps

Open the dhcp client config file located at

/etc/dhcp3/dhcpclient.conf

Replace the current hostname or add to file if none exists

send host-name "LorenzBBB1"

And restart networking

sudo /etc/init.d/networking restart

BBB comes with the argstrom distro, and as you can see from my update I just didn't have a /etc/dhcp3. After a "opkg list | grep dhcp" I noticed a dhcp-client. I did "opg install dhcp-client", and got /etc/dhcp as a result (no dhcp3), and it had a dhcpclient.conf, I edited it as you suggested. and rebooted. No change in behavior. –  Lorenz03Tx Oct 10 '13 at 15:02

I'm just learning about this too, so forgive obvious answers.

The *.local pattern is served by the avahi-daemon service. The avahi daemon only works with the Bonjour/Zeroconf/mDNS system, which not part of Windows by default, but it is on Apple and Linux typically. You can install bonjour for Windows. See this link for ideas: How can I resolve .local addresses in Windows?

I'm guessing that to get the BBB to work for everyone, I think you want to have both avahi and netBIOS running.
