<div class="gmail_quote">2009/3/17 Krsnendu dasa <<a href="mailto:krsnendu108@gmail.com">krsnendu108@gmail.com</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I have just upgraded Hardy to Intrepid with LTSP backports from Stefane. On the server I added ppa repository, then apt-get update then apt-get install ltsp-standalone-server I moved the old changeroot (actually I deleted it. It would have been interesting to try the old one again.) then ran ltsp-build-client to create a new client changeroot. I have two types of clients: ones that work and ones that don't. The ones that work are P4 with 256MB RAM. The ones that don't work are Compaq Deskpro EN Series SFF P2 400MHz 64MB RAM. These worked fine with Hardy (ltsp 5) and K12LTSP (ltsp 4.2) Tried with 128 MB RAM. Still failed. The ubuntu flash screen comes up then freezes part way across. Pressing Alt-ctrl-F1 reveals..this is the error message Negotiation: ..size = 175556KB bs=1024, sz=175556 Kernel call returned: Broken pipe Reconnecting Negotiation: ..size = 175556KB Error: Ioctl/1.1a failed: Bad file descriptor Any ideas what might be wrong? Size = 175556KB seems a worry. It is much more than the RAM on the machine. Can I downgrade to the Intrepid ltsp packages and see if they will work? Is it possible to use Hardy changeroot? </blockquote></div> I tried this fix from another thread. <div style="margin-left: 40px;">In my case(ubuntu 8.10), the problem was caused by the ltsp-client-setup init script. I solved the issue by comenting out the stuff about NBD configure_nbd() { # Restart nbd so -persist will work nbdcmd=`pgrep -l -f "/dev/nbd0 -persist" | cut -d " " -f "2-"` if [ -n "$nbdcmd" ]; then nbd-client -d /dev/nbd0 sleep 0.5s nbd-client -c /dev/nbd0 if [ "$?" = "1" ]; then $nbdcmd fi fi } </div> I commented out this part and got a bit further. This is the error I have now. Setting up LTSP client... Disconnecting: que, disconnect, sock, done [ 30.519994] nbd0: Receive control failed (result -32) Kernel call returned: Broken pipe Reconnecting Negotiation: ..size = 175556KB Error: Ioctl/1/1.a failed: Bad file descriptor Any clues how to fix this?
