Follow-up, amrecover gives the same error whether run from the server/client or from another client.
On the server/client I also ran: $ amservice mums.jgcomp.com bsdtcp noop < /dev/null Request failed: tcpm_recv_token: invalid size: "Executing: \ /usr/sbin/amandad -auth=bsdtcp amdump amdumpd\n" According to one wiki document, http://wiki.zmanda.com/index.php/Selfcheck_request_failed this suggests a failure in bsdtcp authentication. BTW the string "/usr/sbin/amandad -auth=bsdtcp amdump amdumpd" matches the "ExecStart=" value in the systemd service file "/usr/lib/systemd/system/amanda@.service".
