I've been having trouble the last week or two ssh'sing into the machine, and printing from the machine when I am sitting at the keyboard. I also could not connect to my external firewall when sitting at the keyboard. I keep a Google Pixel 4a tethered to the USB hub for charging. The Android phone is running Android 12, and the phone is set to "USB Tethering". The phone is fully patched, too. I found if I reboot the machine with the phone tethered, then the machine uses the Android phone as the ethernet connection. It literally calls the connection "ethernet", as if it was using the network adapter. This is new behavior over the last week or two. This is unexpected behavior for three reasons. First, it is new behavior. Second, the wired gigabit ethernet connection is not used by default. And thrid, the Android phone's connection is called "ethernet" instead of something more meaningful like "USB" or "Android" or "wired hotspot". The third item ("ethernet" name when using Android phone) was misleading enough to waste a lot of time troubleshooting the issue. I thought I had an odd firewall issue or a mDNS issue. The reason I was having so many troubles, like printing and ssh, is the Android phone uses Wifi and it is on a different VLAN and subnet to keep traffic segregated from my trusted internal network. ----- It looks like I am running network-manager via systemd: # service systemd-networkd status ● systemd-networkd.service - Network Service Loaded: loaded (/lib/systemd/system/systemd-networkd.service; disabled; vendor prese> Active: inactive (dead) Docs: man:systemd-networkd.service(8) # service network-manager status ● NetworkManager.service - Network Manager Loaded: loaded (/lib/systemd/system/NetworkManager.service; enabled; vendor preset: > Active: active (running) since Mon 2022-05-23 21:16:52 EDT; 59min ago Docs: man:NetworkManager(8) Main PID: 928 (NetworkManager) Tasks: 3 (limit: 76693) Memory: 12.0M CGroup: /system.slice/NetworkManager.service └─928 /usr/sbin/NetworkManager --no-daemon ... --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.24 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: KDE DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2022-02-05 (107 days ago) InstallationMedia: Kubuntu 20.04.3 LTS "Focal Fossa" - Release amd64 (20210819.1) IpRoute: default via 172.16.1.1 dev enp4s0 proto dhcp metric 100 169.254.0.0/16 dev enp4s0 scope link metric 1000 172.16.0.0/12 dev enp4s0 proto kernel scope link src 172.16.2.10 metric 100 Package: network-manager 1.22.10-1ubuntu2.3 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 5.13.0-44.49~20.04.1-generic 5.13.19 Tags: focal Uname: Linux 5.13.0-44-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dialout dip lpadmin lxd plugdev sambashare sudo _MarkForUpload: True nmcli-con: NAME UUID TYPE TIMESTAMP TIMESTAMP-REAL AUTOCONNECT AUTOCONNECT-PRIORITY READONLY DBUS-PATH ACTIVE DEVICE STATE ACTIVE-PATH SLAVE FILENAME Ethernet 5d31ea14-c1cd-318f-a982-09ce6723dadb ethernet 1653403311 Tue 24 May 2022 10:41:51 AM EDT yes -100 no /org/freedesktop/NetworkManager/Settings/1 yes enp4s0 activated /org/freedesktop/NetworkManager/ActiveConnection/4 -- /etc/NetworkManager/system-connections/Ethernet.nmconnection nmcli-nm: RUNNING VERSION STATE STARTUP CONNECTIVITY NETWORKING WIFI-HW WIFI WWAN-HW WWAN running 1.22.10 connected started full enabled enabled enabled enabled enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1975549/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
