I have configured the two servers that the first one serves the image and there I have 28 process-pairs of the combo: nobody /bin/sh /usr/sbin/nbdrootd /opt/ltsp/images/i386.img nobody /bin/nbd-server 0 /opt/ltsp/images/i386.img -r -C /dev/null The second server holds the swap files. On this I have 248 pairs of: nobody /bin/sh /usr/sbin/nbdswapd nobody /bin/nbd-server 0 /tmp/tmp.yRYaPc2913 -C /dev/null Obviously the 'rm -f $SWAP' doesn't work quite well. Concerning /etc/hosts.allow: After the ubuntu hardy installation, only the nbdrootd-line was in there. I added the nbdswapd-line now, but this should be part of the installation. I'll see during the next week, if the keepalive options helps.

The client are not switched off every night. It's a production environment and people stay logged in or only log out without powering down the machine. So you cannot simply remove all swapfiles. The servers run for months without reboot. In my original post, I mentioned an older discussion, where vagrant at freegeek.org wrote at Wed, 16 May 2007 09:04:56 -0700: > you're free to implement whatever scheme for the filename you like by > putting it in the configuration file /etc/ltsp/nbdswapd.conf: > IP=$(magic_command_to_get_ip) > SWAP=/path/to/your/preferred/swap/file/$IP I personally would prefer, if the swapfiles are named like /tmp/<clientname>.swap, but I have no idea, what the 'magic_command_to_get_ip' could look like. What environment is passed to /usr/sbin/nbdswapd to extract the ip/name of the caller?
