[Bug 90388] Re: hostname supplied by dhcp server is not used
Hello?? It used to work in Hardy!!! Therefore either a newer version of dhcp3-client or network-manager or a change to the default configuration by the ubuntu developers must have caused this to stop working. The ability to centrally manage large numbers of workstations includes the ability to set the hostname from the server. I want to express my irritation and frustration over this and other alterations made to ubuntu that makes System administrators lifes miserable. Do you know how much time I have spend to debug this stupid non-bug? Another problem are these UUID's that popped up in /etc/fstab, in the grub config, even in the initrd for specifying the `resume partition'. In a network of Ubuntu workstations, I want to: * set hostnames from the server, via DHCP. NOT the other way around, i.e. let the client change the DNS server records. I do not want to have to create lots of little scripts like in the solution of Christoph Dwertmann for something that used to work without all that. * I do not want to have network manager at all in managed clients. The users are not allowed to alter the network settings, the network is configured once at boot via dhcp and that is that. No network-manager needed. Make it removable. * be able to use a single image to roll out to clients. This means that UUID's are not handy to have in /etc/fstab, or in the grub config files. The UUID of partitions in the master image will be wrong for the clients. I do not want to have to fix all the places in /etc/fstab, /boot/grub/grub.cfg, /etc/grub.d/*, the initrd file even, to replace the UUID for the clients UUID's. I just want to use the bloody device files! Just /dev/sda. Can the developers please make it an option to use device files throughout?

It's a shame Ubuntu can't get hostname from DHCP server. It's 2010. Bug is almost three years old. But before I read the comments I didn't realize that X server may be affected by hostname change. Any thoughts how can this be handled? I really want this fixed. I don't use NetworkManager, for me networking script is preferable. I read on some forum that people just use another dhcp client to get things working. Won't it be better to ship Ubuntu with fully working DHCP client?

Another approach might be to set /etc/hostname to the value from DHCP server, and leave the current hostname alone. That would set the host name to correct value at next boot, without any clash with netowork manager behaviour or a running X [ and hopefully the name would not change between reboots :) ] As 9.10 enables parallel initscripts with upstart, having the network up before gdm(or kdm) can be hard, you may need to change ordering of initscripts, or it may be undesirable (startup seems slower).

[Bug 90388] Re: hostname supplied by dhcp server is not used
We solved it by putting hostname $new_host_name into a file at /etc/dhcp3/dhclient-exit-hooks.d/ Thanks Thomas for the tip. default host-name NO-NETWORK did not work, when network was not available hostname was none (or blank, i'm not sure) as jason said. Booting the machine took ages, so we fleed to other solutions. Maybe as a fix, for this bug, a sethostname script can be included in dhclient-exit-hooks.d. It can be disabled by default like the debug script there. Be aware that, we had problems with default ubuntu installation(and loads of packages we install afterwards). smart NetworkManager made DCHP client ask for leases after gdm started, so no-X-running condition was not satisfied at that stage. We solved this by populating /etc/network/interfaces as usual. The default had only loopback interface there. Here is a script, checks for only a running gdm though. $new_host_name is set by dhclient before calling this; === /etc/dhcp3/dhclient-exit-hooks.d/sethostname == # This script sets the machine hostname to the hostname sent from the DHCP server. # Beware, if this happens while X is running, there will be problems, so the script checks # for a running gdm and does not change the hostname if it detects one. # If you want to enable this script, change SETHOSTNAME to yes SETHOSTNAME=yes if [ $SETHOSTNAME = yes ]; then if test -r /var/run/gdm.pid ps -ef | grep $(cat /var/run/gdm.pid) | grep -q /usr/sbin/gdm ; then echo $(date): GDM running, not changing host name /tmp/dhcp-sethostname.err ; else hostname $new_host_name; fi fi ** Attachment added: sethostname http://launchpadlibrarian.net/13221941/sethostname -- hostname supplied by dhcp server is not used https://bugs.launchpad.net/bugs/90388 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi, dhclient.conf does not need modifications. On ubuntu, /etc/network/interfaces file has only loopback interface, This causes the eth0 interface to be down until glorious NetworkManager kicks in.

at least in dapper, i couldn't tell if that's what this bug was attached to, you can remove /etc/hostname and the hostname from the server will be used. however, there is the problem that if you do this and there isn't an entry for the ip address, the /etc/dhcp3/dhclient-script will set the hostname to blank which is no good. sudo will no longer work for starters. i think that might should be a different bug. -- hostname supplied by dhcp server is not used https://bugs.launchpad.net/bugs/90388 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The reverse lookup can return a different host name than declared for the kernel; I do not see any problem with that, given that different network interfaces can belong to different domains, let alone have different names. -- hostname supplied by dhcp server is not used https://bugs.launchpad.net/bugs/90388 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 90388] Re: hostname supplied by dhcp server is not used
A hook script in /etc/dhcp3/dhclient-exit-hooks.d/ should be able to
fix this.
As has been mentioned, X might get angry, but you could always check for
a running X before changing the hostname (assuming it's better to have
the wrong hostname than it is to have a non-working X).
Signaling a no network error to users could be done with /etc/motd,
/etc/issue and/or xmessage
A slight improvement on the interface guessing might be chasing up the
default gateway:
host $(ifconfig `ip route | awk '/^default/{print $5}'` | sed -rne
's/.*inet addr:(.*)Bcast.*/\1/p') | cut --delim \ --field 5

This cannot be enabled by default in dhcp client. X becomes very angry if you change the hostname underneath it, so this should only be done at boot time, not when changing the lease at runtime.
