Description of problem: not sure what exactly causing this but I am seeing generic ppp0 profiles created here and there I've executed 3 times this test and one ppp0 was created * Add a new connection of type "gsm" and options "ifname \* con-name gsm apn internet" * Bring "up" connection "gsm" When "gsm" is visible with command "nmcli con show -a" in "10" seconds * Bring "down" connection "gsm" And Unable to ping "redhat.com" When "gsm" is not visible with command "nmcli con show -a" in "10" seconds * Bring "up" connection "gsm" Then "gsm" is visible with command "nmcli con show -a" in "10" seconds And Ping "redhat.com" debug log attached Version-Release number of selected component (if applicable): NetworkManager-1.0.6-27.el7.x86_64 ModemManager-1.1.0-8.git20130913.el7.x86_64 usb_modeswitch-1.2.7-6.el7.x86_64 kernel-3.10.0-327.el7.x86_64 debug log attached it has > 8000 lines as the test was executed 3 times. Consider just the last test

[root@wlan-intel-6150 ~]# nmcli d DEVICE TYPE STATE CONNECTION ttyUSB2 gsm connecting (getting IP configuration) gsm eth0 ethernet disconnected -- eth1 ethernet disconnected -- eth10 ethernet disconnected -- eth2 ethernet disconnected -- eth3 ethernet disconnected -- eth4 ethernet disconnected -- eth5 ethernet disconnected -- eth6 ethernet disconnected -- eth7 ethernet disconnected -- eth8 ethernet disconnected -- eth9 ethernet disconnected -- lo loopback unmanaged -- ppp0 unknown unmanaged -- for a little while I can see ppp0 device too, this may be a reason ppp0 connection is assumed
Is this still a problem on recent versions of NM?
Pavlin, could you please retest and close if it's not visible with current version? Thank you a lot.
