Try "dpkg-reconfigure nbd-server". That should ask some questions and generate a correct config file.

If it doesn't, remove the config file and try again.

[Richard Huddleston (rhuddusa)]

dpkg-reconfigure nbd-server correctly generated the config file

I am running Lucid 64 and there is no config file either. What should the correct values for the reconfigure command be?

In the future, please don't send mail to me directly. Instead, use the
bug report. That way, other people can also benefit from what I may or
may not be able to answer.

In this particular case, you need to just call 'dpkg-reconfigure
nbd-server', and fill out what files you wish to serve to your clients.

Alternatively, just read 'man 5 nbd-server', which documents the
configuration file format.

Actually, you did do that. Never mind, sorry about that.

Could you please provide a sample config file for comparison, for use with LTSP on Lucid Lynx?

I have attempted to fill in what I think are correct answers [1 server, serve /opt/ltsp/i386 and port 2000] but this does not seem to be making much difference and I still get blank screens on my clients.

The output of

man 5 nbd-server

contains two at the end.

Also, if you call 'dpkg-reconfigure -plow nbd-server', you should get a
set of questions that help you generate a config file.

Actually, /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default includes the following line by default:

  append ro initrd=initrd.img quiet splash nbdport=2001

So which port number should I use: 2000 or 2001? Using one or another doesn't seems to be a difference, because all works exactly equal in both cases.

Aside from that, I got messages like the following from inetd into the syslog:

  Jul 16 21:43:17 servidor inetd[2095]: 2001/tcp: bind: Address already in use

Any clues?

For those in this bug report that are using LTSP:
LTSP in Ubuntu doesn't use a configuration file for nbd-server. It launches it via inetd instead:
$ grep nbd /etc/inetd.conf
9572 stream tcp nowait nobody /usr/sbin/tcpd /usr/sbin/nbdswapd
2000 stream tcp nowait nobody /usr/sbin/tcpd /usr/sbin/nbdrootd /opt/ltsp/images/i386.img

The nbdswapd and nbdrootd wrapper scripts then launch nbd-server with a "-C /dev/null" option, so user configuration files are ignored.

Anyone using LTSP who is having a problem with the nbd-server configuration should file a bug report under LTSP (ubuntu) instead, or just visit the IRC #ltsp channel in freenode or use its mailing list to get help in troubleshooting his problems.

[Juan Pablo (juanps90)]

Like he said, nbd in Ubuntu should run under inetd ( sudo apt-get install openbsd-inetd ), and the lack of a configuration file for nbd-server shouldn't be an issue.

[David McNeill (davemc)]

The message about no config file happens because you accepted the default of 0 number of servers to run in the ncurses dialog 'Configuring nbd-server', hence no config file is written, since no servers were requested.

Number of nbd-server instances to run: 0 <<<< change this to 1 for example, and then specify the file and port.

Then you will get a config file that you can look at and modify.

If you run dpkg-reconfigure nbd-server and still specify 0 servers, you will still get no config file.

Jaunty is EOL, closing this bug report.
