It was really confusing, because with the hostname set in the hostname file, I was able to ping 'Myname' successfully, but DNS didn't work and the command hostname returned 'box'. Once I added the bootcode, everything worked. I think I've established that this bootcode method is (if not unique) special to TC; presumably so that a LiveDisc user can set the hostname of a CD based system. I don't have a problem with that, but they shouldn't be independent. I'd have expected the bootcode to write to the hostname file, to keep everything consistent.

Cheers, Ralph. FC14 seems to use the /etc/sysconfig tree to hold this kind of info /etc/sysconfig/network:HOSTNAME=myhostname /etc/rc.sysinit reads the sysconfig tree Regards Andy -- Next meeting: Bournemouth, Tuesday 2011-04-05 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ How to Report Bugs Effectively: http://goo.gl/4Xue
[Dorset] Setting up hostname in Linux
Hi,
Here is a really basic question; how is the hostname defined in modern Linux
distributions? Generally this is done for us by the installer, so we don't have
to know how to do it, other than fill in the name of the PC into the box
provided.
The reason I'm asking is that I've just spent about a week (off and on) trying
to get DHCP and DNS to work on a Tiny Core Installation. I cracked it about
half an hour ago, when I discovered that the hostname file had one thing in it
('Myname', which I had written there) and the output of the command 'hostname'
gave 'box', which is the default for TC. I had to add the bootcode
host='Myname' to get the right answer and then my DNS server started answering
requests for pings etc to 'Myname'.
Maybe my memory is faulty, but my recollection of doing this on earlier Unix
systems, (like Solaris), is that the hostname went into the file called hostname
(or similar) and that did it (after a reboot). Is that right, or should I be
worried about my powers of recall?

Generally this is done for us by the installer, so we don't have to know how to do it, other than fill in the name of the PC into the box provided. I believe it's actually somewhat distro-specific. On Arch, it's stored in /etc/rc.conf, and further repeated in /etc/hosts on the first line, which is usually the loopback 127.0.0.1 line. -- Next meeting: Bournemouth, Tuesday 2011-04-05 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ How to Report Bugs Effectively: http://goo.gl/4Xue

If the system has a fixed IP address, use it; if not, use 127.0.1.1. Your /etc/hosts will then look like: 127.0.0.1 localhost 10.0.0.100 system.example.com system or 127.0.0.1 localhost 127.0.1.1 system.example.com system That will fix the 'hostname -f' problem. -- You can have everything in life you want if you help enough other people get what they want - Zig Ziglar.
