License

I put this code under the GPLv2

Download

Until I figure out how to upload a tarball to the wiki, you can download fai-updater from [1]

Required packages

for the frontend, you need the Curses::UI perl module, in Debian you get it via

apt-get install libcurses-ui-perl

On the client side, fai-client is needed and of course a FAI configuration which is update-safe.

Install

Just unpack the tarball.

Command line options

 updater-curses [options] <netgroup|-H host1,host2,...>
 --help            display this help message
 --version         print version
 -o                ordered mode: don't randomize order of hosts
 -s <number>       number of updates running simultanously
 -n                dryrun mode: use a dummy-script instead of really 
                   contacting the clients

Connecting to the clients

A script using ssh is included, but of course you can edit it to match your own needs.

To be able to connect to the clients using the provided libexec/faiupdate, you need to have some way to access them via ssh as root without entering a password.

A solution for this is to install a matching file as /root/.ssh/authorized_keys, start ssh-agent and load the private key into it _before_ starting fai-updater.

Another, but from a security point of view dangerous, possibility is to use a passphrase-less ssh private key into the account under which you run fai-updater.

Some comments on the code

I know the code is quite rough, as though I tried programming cleanly, a lot of hacks have slipped in, and I don't have the time to clean up the code right now due to my diploma thesis' deadline ;)

If you have any questions or suggestions, feel free to write me.
