i don't know if this has been answered yet or not, but try this: 1. have one of the machines mirror the debian archives, including the non-US crypto-related stuff (secure shell - "ssh" - is essential). set up /etc/exports so that all local machines can NFS mount them. 2. set up all machines so that they NFS mount the debian main archive as /debian, and the debian non-US archive as /debian-non-US. 3. install ssh on all machines, and set them up to allow one machine to have password-less root access to all of the others. 4. when you need to install/upgrade a package, write a little script like this: #! /bin/bash # list of hosts to execute commands on hosts='host1 host2 host3 host4 .....' # command(s) to run. can be multiline command if needed cmd='dpkg -iBE /debian/path/to/package.deb' for i in $hosts ; do ssh $i $cmd done if you need to do more complex things on each machine in turn, then start by write a shell or perl script to do the job, then copy it to each machine (using scp) and execute it on each machine. e.g. if you have written a script called "fix-stuff.sh" which understands the command line options "foo" and "bar", then a little wrapper script like the following would copy it to all machines and execute it: #! /bin/bash # list of hosts to execute script on hosts='host1 host2 host3 host4 .....' for i in $hosts ; do scp fix-stuff.sh $i:/tmp ssh $i "/tmp/fix-stuff.sh foo bar" done these samples could easily be made generic so that they got $cmd or the name of the script to copy&exec from the command line. craig -- craig sanders -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
