raspbian wheezy does not send hostname to DNS

Edit the hostname into /etc/dhcp/dhclient.conf

Gordon

Hi,

I already tried to hardcode the hostname in /etc/dhcp/dhclient.conf like

send host-name "andare.fugue.com"; #send host-name = gethostname();

as this is recommended in some fora, but in the DNS there's still "name = noname."

Do you know some other tricks?

Thanks in advance, best regards,

Markus

It does. Out of the box. Both of my Raspberries have their hostnames in /etc/hostname. Usual way is to set the hostname in raspi-config -> Advanced Options -> Hostname when installing/configuring.

Hi,

primary config during install indeed writes the desired hostname (raspbian) into /etc/hostname.

Also, in the /etc/hosts there's a line reading "127.0.1.1 raspbian".

Networkmanager ist not (yet) installed.

And, both raspberries can send the hostname to the DNS server when loaded with the "pidora" SD card. So, the hardware, as well as the DNS seem OK.

Try this link.

I used this years ago to tell my router what my debian box was called..

I wonder if it's the /etc/dhcp3/dhclient.conf file instead then...

All mine have static IPs so it's never been a problem here..

Hi Gordon,

some years ago I was able to use static IPs, but well, mea culpa -- in the meantime I have so many machines and often use them in parallel, that it's impossible to remember all their IPs, or to put them into all the /etc/hosts files. I need dhcp, I have no other choice :-)

Well, out of these files

root@raspbian:/etc# find | grep dhcp ./dhcp3 ./dhcp3/dhclient-enter-hooks.d ./dhcp3/dhclient-enter-hooks.d/samba ./samba/dhcp.conf ./dhcp ./dhcp/dhclient-exit-hooks.d ./dhcp/dhclient-exit-hooks.d/debug ./dhcp/dhclient-exit-hooks.d/rfc3442-classless-routes ./dhcp/dhclient-exit-hooks.d/ntp ./dhcp/dhclient-enter-hooks.d ./dhcp/dhclient-enter-hooks.d/samba ./dhcp/dhclient-enter-hooks.d/debug ./dhcp/dhclient.conf

I edited the downmost one.

Installed packages are

root@raspbian:/etc# dpkg -l | grep -i dhc ii isc-dhcp-client 4.2.2.dfsg.1-5+deb70u6 armhf ISC DHCP client ii isc-dhcp-common 4.2.2.dfsg.1-5+deb70u6 armhf common files used by all the isc-dhcp* packages

Hi Gordon, Philosopher, Paul, hi everybody!

Many thanks for your help -- finally I remembered a trick that helped a lot on Mandriva Linux some time ago.

Since it seems to be just destiniy whether dhclient works or not in debain OSes, I threw it down and replaced it with dhcpcd ==>

apt-get remove isc-dhcp-client isc-dhcp-common apt-get install dhcpcd

After reboot nmap, nslookup &Co finds the box by name now and I can log into it by simply doing a "ssh root@raspbian".

Thanks again, best regards,

Markus

Markus,

I see you already solved this by going with dhcpcd, but in case someone looks at this in the future...

Is it possible that the missing '=' in the uncommented line messed things up? (I could try removing the '=' from my dhclient.conf, but I'm not in the mood to mess with things which are working :-)

Cheers.

Jim
