Sorry this is long.... I'm back getting to grips with NM, after time out on other aspects. I'm using the git master (1.9.1), on a SysV system, no graphical desktop, no netconfig or resolvconf. Looks like quite a few updates since I was last engrossed in it, so it may be that my configs and - more likely - understanding is a bit out of date.
The system has eth0 and a gsm connection (via ModemManager). I have in /etc/network/interfaces: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp NetworkManager.conf is: [main] plugins=ifupdown,keyfile dns=default rc-manager=file [connectivity] [ifupdown] managed=true First off, up/down: from reboot root@wg:~# nmcli -c no conn show NAME UUID TYPE DEVICE eth0 129206d8-d28f-47c7-9f9a-f9ddb1cb5218 ethernet eth0 Ifupdown (eth0) 681b428f-beaf-8932-dce4-687ed5bae28e ethernet -- O2 42bf3c07-9dd7-45f6-ba08-37dfc8a7a537 gsm -- Vodafone e0f97177-2f8e-4ed4-9942-7b4e499397cc gsm -- root@wg:~# nmcli -c no conn down eth0 Connection 'eth0' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/1) root@wg:~# nmcli -c no conn show NAME UUID TYPE DEVICE Ifupdown (eth0) 681b428f-beaf-8932-dce4-687ed5bae28e ethernet eth0 O2 42bf3c07-9dd7-45f6-ba08-37dfc8a7a537 gsm -- Vodafone e0f97177-2f8e-4ed4-9942-7b4e499397cc gsm -- root@wgs:~# nmcli -c no conn up eth0 Error: unknown connection 'eth0'. root@wg:~# nmcli -c no conn up 681b428f-beaf-8932-dce4-687ed5bae28e Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/3) root@wg:~# nmcli -c no conn show NAME UUID TYPE DEVICE Ifupdown (eth0) 681b428f-beaf-8932-dce4-687ed5bae28e ethernet eth0 O2 42bf3c07-9dd7-45f6-ba08-37dfc8a7a537 gsm -- Vodafone e0f97177-2f8e-4ed4-9942-7b4e499397cc gsm -- root@wg:~# nmcli -c no conn down eth0 Error: 'eth0' is not an active connection. Error: no active connection provided. Puzzling how eth0 is-then-isn't a valid connection name..? Maybe it's to do with the ifupdown/managed setting - and, really, I'm not sure whether I want to be using this or not. [The overall goal is to understand whether/how the system will behave, for example, if the eth connection dies for some reason. But it looks like I've got something fouled up that I need to better understand first] This also causes me confusion if I try to take the eth down: root@wg:~# nmcli -c no conn show NAME UUID TYPE DEVICE eth0 e76aaae3-b320-4f64-9402-2a4ff8f28e01 ethernet eth0 Ifupdown (eth0) 681b428f-beaf-8932-dce4-687ed5bae28e ethernet -- O2 42bf3c07-9dd7-45f6-ba08-37dfc8a7a537 gsm -- Vodafone e0f97177-2f8e-4ed4-9942-7b4e499397cc gsm -- root@wg:~# cat /etc/resolv.conf # Generated by NetworkManager nameserver 192.168.10.254 root@wg:~# nmcli conn up O2 PPP generic driver version 2.4.2 PPP BSD Compression module registered PPP Deflate Compression module registered Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/2) root@wg:~# cat /etc/resolv.conf # Generated by NetworkManager nameserver 192.168.10.254 nameserver 82.132.254.2 nameserver 82.132.254.3 root@wg:~# nmcli conn down eth0 Connection 'eth0' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/1) root@wg:~# cat /etc/resolv.conf # Generated by NetworkManager search lan nameserver 192.168.10.254 nameserver 82.132.254.2 nameserver 82.132.254.3 root@wg:~# ping www.google.com PING www.google.com (172.217.17.100): 56 data bytes 64 bytes from 172.217.17.100: seq=0 ttl=51 time=22.627 ms <- Ethernet speed ^C --- www.google.com ping statistics --- 2 packets transmitted, 1 packets received, 50% packet loss round-trip min/avg/max = 22.627/22.627/22.627 ms root@wg:~# nmcli -c no conn show NAME UUID TYPE DEVICE Ifupdown (eth0) 681b428f-beaf-8932-dce4-687ed5bae28e ethernet eth0 O2 42bf3c07-9dd7-45f6-ba08-37dfc8a7a537 gsm ttyMux1 Vodafone e0f97177-2f8e-4ed4-9942-7b4e499397cc gsm -- root@wg:~# nmcli conn down 681b428f-beaf-8932-dce4-687ed5bae28e Connection 'Ifupdown (eth0)' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/3) root@wg:~# cat /etc/resolv.conf # Generated by NetworkManager nameserver 82.132.254.2 nameserver 82.132.254.3 root@wg:~# ping www.google.com PING www.google.com (173.194.122.242): 56 data bytes 64 bytes from 173.194.122.242: seq=0 ttl=41 time=592.168 ms <- GSM speed 64 bytes from 173.194.122.242: seq=1 ttl=41 time=531.795 ms 64 bytes from 173.194.122.242: seq=2 ttl=41 time=511.506 ms 64 bytes from 173.194.122.242: seq=3 ttl=41 time=531.117 ms 64 bytes from 173.194.122.242: seq=4 ttl=41 time=510.785 ms ^C --- www.google.com ping statistics --- 6 packets transmitted, 5 packets received, 16% packet loss round-trip min/avg/max = 510.785/535.474/592.168 ms Any advice please on things to check and a good way to work through and tidy this? (Not at all keen on the new style 'standard input' presentation on a console/tty, tbh - the old style colouring used to work ok I think) _______________________________________________ networkmanager-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/networkmanager-list
