Hi everybody. I have to clone a large number of machines, so i installed udpcast on the linux partition of my dual boot machines. I'd like, from the server, to do something like this: for i in `seq 0 9`; do ssh machine$i "udp-receiver -f /dev/hda1"; done to start on every machine the udp-receiver and clone the windows partition. udp-receiver starts (i see it listening on port 9000), but when i start cloning it exits... I tried also putting the process in background, using nohup and using the option --nokbd, but nothing changes. Anybody tried somthing like this before or have any idea of what's going wrong? ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/
You have to register udp-reciever as a service in /etc /rc.d/ There is usualy skeleton code in this directory that you can just replace the [service] with udp-reciever Then change your script to /etc/rc.d/yourscript start Stephen Kaspersen Software Developer Spectrum Visual Networks A Top Technology 100 Company ----- Original Message ----- From: "sistemista windows/linux cosenz int.5834" <matteo.balduzzi@cdc.polimi.it> To: <udpcast@udpcast.linux.lu> Sent: Wednesday, September 15, 2004 8:51 AM Subject: [Udpcast] Udpcast and ssh

I'm not sure what you're talking about here, but normally udpcast doesn't use any files in /etc , nor in /rc.d Busybox does use files in /etc/, but for purposes not directly related to udpcast. Regards, Alain

If he edits for example /etc/rc.d/skeleton in Suse 8.2 changes the line ' FOO_BIN=/usr/sbin/FOO ' to ' FOO_BIN="udp-receiver -f /dev/hda1 -nokbd" ' and saves the file as /etc/rc.d/udp-reciever Then ssh in type : /etc/rc.d/udp-reciever start After exiting udp-reciever will be running as a service the same way one uses /etc/rc.d/xinetd start to allow ftp-ing to a server If udp-reciever was stopping because it was bound to a session this would no longer be the case I have tried it and it works Stephen Kaspersen Software Developer Spectrum Visual Networks A Top Technology 100 Company ----- Original Message ----- From: "Alain Knaff" <alain@knaff.lu> To: <udpcast@udpcast.linux.lu> Cc: "Stephen Kaspersen" <stephen@spectrumvns.com> Sent: Wednesday, September 15, 2004 10:40 AM Subject: Re: [Udpcast] Udpcast and ssh

I tried this myself on SuSE (using openssh version 3.8p1-33 and udpcast version 2004-05-31), and it worked (both with and without the --nokdb version). What output or error message are you seeing when you try it? Did you confirm that it works when starting the same udpcast command locally on the target machine? Regards, Alain

If it works for you then probably is because i use the commercial version of ssh (3.2.9.1) on server and on clients...

Yes, the same command works if executed locally. Beeing in a hurry i "resolved" with 39 xterms connected to the 39 clients, but i hope not having to do it again... ;-)

Alain
Anyway, thank you all for your help Ciao, Matteo

Or use the -f option to ssh, which is imho a better solution. Although, you probably already make use of certicates for this, if you don't you would first need to type passwords and -f will wait untill you authenticated before backgrounding the ssh process.
