These clients (Compaq Deskpro SFF PII 400 with 128MB RAM) don't work. It was also working fine previously with Hardy. As I have upgraded from Hardy, there is an old lts.conf file that I will rename. Maybe there is a setting there that is causing the problem, (like nbd swap). I will let you know how I go when I try it at school tomorrow. Have the options in lts.conf changed since Hardy? If so where can I see what the choices are? <div class="gmail_quote">2009/3/17 Stéphane Graber <<a href="mailto:stgraber@ubuntu.com" target="_blank">stgraber@ubuntu.com</a>><div> <div></div><div class="h5"> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Something seems to reset your nbd connection. The part of code you commented is the one forcing nbd to reconnect in persistent mode so by commenting it you disabled the automatic reconnection of the nbd link. That still doesn't explain why just after that, the nbd link is disconnected as AFAIK there's nothing in the code that causes another disconnection. Do you have nbd swap or something similar to that enabled ? It might be a conflict between regular nbd (squashfs image) and the nbd used for network swap although this one should no longer be used as compcache should be preferred. What kind of thin client is that and did you try with another one ? Is your network reliable ? - -- Stéphane Graber Ubuntu developer <a href="http://www.ubuntu.com" target="_blank">http://www.ubuntu.com</a> -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - <a href="http://enigmail.mozdev.org" target="_blank">http://enigmail.mozdev.org</a> iEYEARECAAYFAkm/FxYACgkQjxyfqkjBhuw7aQCgizSUOeGaPlWDRz789fiB8c3J APYAn1Kjnsew/2dFEfYRdSUE1FZWqJtd =6gjB -----END PGP SIGNATURE----- </blockquote></div></div></div> </blockquote></div>
