Silent client registration for Subscription Management Tool (SMT)

Question

In the documentation for the Subscription Management Tool (SMT) for Suse repository management, there are 4 ways to register a client with the SMT server.

One of these is by running the clientSetup4SMT.sh script. The documentation does not explain any way to perform a silent installation using this script, but is there any way to achieve it?

Answer 1

In the source of the clientSetup4SMT.sh script the following line of documentation can be found:

Usage: $0 --host <hostname of the SMT server> [--fingerprint <fingerprint of server cert>] [--yes]

The two options --fingerprint and --yes are the options we need.

--fingerprint is the CA certificate fingerprint. The CA certificate can be found on the SMT server at http://FQDN/smt.crt (FQDN). Alternatively it can be accessed at /srv/www/htdocs/smt.crt.

Getting the fingerprint from the server is most easily done by deliberately specifying an invalid fingerprint in the script's --fingerprint option:

clientSetup4SMT.sh --host <hostname of the SMT server> --fingerprint 'somestring' --yes

This will return:

Server fingerprint: <actual server fingerprint> and given fingerprint:  <wrong server fingerprint> do not match, not accepting cert. Abort.

Copy the server fingerprint and paste it into the command as so:

clientSetup4SMT.sh --host <hostname of the SMT server> --fingerprint '<actual server fingerprint>' --yes

The above command will run silently.

Answer 2

Just rem out the bits that ask for input etc in the .sh script itself...
