Fix up for review with https://github.com/candlepin/subscription-manager/pull/1562 To verify this BZ I did not have to edit the /etc/dbus-1/system.conf file. The send_type did not have to be edited to get dbus to work and dbus.service did not need to be restarted:
[root@stoner-rhel-74 subman1.9.7]# cat /etc/dbus-1/system.conf | grep send_type
<deny send_type="method_call"/>
<allow send_type="signal"/>
<allow send_requested_reply="true" send_type="method_return"/>
<allow send_requested_reply="true" send_type="error"/>
And running the original command that got an access denied now works successfully:
[root@stoner-rhel-74 subman1.9.7]# dbus-send --system --print-reply --dest='com.redhat.RHSM1' '/com/redhat/RHSM1/RegisterServer' com.redhat.RHSM1.RegisterServer.Start
method return sender=:1.37865 -> dest=:1.37926 reply_serial=2
string "unix:abstract=/var/run/dbus-hFLSsUWi7q,guid=1cc8ab09c9c716d9f755819358f50415"

Description of problem ====================== Making a dbus call to start the RegisterServer using the dbus-send or busctl utilities fails with an Access Denied. This appears to be caused by the /etc/dbus-1/system.conf file rejecting send_type="method_call" Version-Release number of selected component (if applicable) ============================================================ [root@stoner-rhel-74 ~]# rpm -qa | grep subscription subscription-manager-gui-1.19.1-1.git.9.908316a.el7.x86_64 subscription-manager-1.19.1-1.git.9.908316a.el7.x86_64 subscription-manager-initial-setup-addon-1.19.1-1.git.9.908316a.el7.x86_64 subscription-manager-migration-1.19.1-1.git.9.908316a.el7.x86_64 subscription-manager-migration-data-2.0.34-1.git.0.2384ef4.el7.noarch How reproducible ================ Always Steps to Reproduce: =================== See Actual results below Actual results: =============== [root@stoner-rhel-74 ~]# dbus-send --system --print-reply --dest='com.redhat.RHSM1' '/com/redhat/RHSM1/RegisterServer' com.redhat.RHSM1.RegisterServer.Start Error org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 1 matched rules; type="method_call", sender=":1.26" (uid=0 pid=2324 comm="dbus-send --system --print-reply --dest=com.redhat") interface="com.redhat.RHSM1.RegisterServer" member="Start" error name="(unset)" requested_reply="0" destination="com.redhat.RHSM1" (uid=0 pid=812 comm="python /usr/libexec/rhsm-service ") Expected results: ================= [root@stoner-rhel-74 ~]# dbus-send --system --print-reply --dest='com.redhat.RHSM1' '/com/redhat/RHSM1/RegisterServer' com.redhat.RHSM1.RegisterServer.Start method return sender=:1.5 -> dest=:1.4 reply_serial=2 string "unix:abstract=/var/run/dbus-XP0szXbntD,guid=e234053b12b7e78b2c48cac758a60d17" Additional info: ================ The fix I made was to edit the /etc/dbus-1/system.conf file like this: <!-- <deny send_type="method_call"/> --> <!-- Signals and reply messages (method returns, errors) are allowed by default --> <allow send_type="method_call"/> Then systemctl restart dbus.service, and reissue the dbus-send.
