Answered in post below
I have a network interface I don't recognize or understand.
ip a s provides the following (sanitized) output:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: wlp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff inet 192.xxx.xx.xxx/xx brd 192.xxx.xx. scope global dynamic noprefixroute wlp2s0 valid_lft 2347sec preferred_lft 2347sec inet6 xxxx::xxxx:xxxx:xxxx:xxxx/xx scope link noprefixroute valid_lft forever preferred_lft forever 4: enx9cebe80718e1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000 link/ether xx:xx:xx:xx:xx:x brd ff:ff:ff:ff:ff:ff
The relevant output from
ifconfig (which I installed for familiarity) is:
enx9cebe80718e1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 ether xx:xx:xx:xx:xx:xx txqueuelen 1000 (Ethernet) RX packets 138 bytes 30067 (30.0 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 573 bytes 98070 (98.0 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Traffic is happening, but small.
My understanding of networks is next to nothing, but nevertheless, all the interfaces I have seen are short, e.g.
My question is, what is
enx9cebe80718e1? And where is the entry for
system and background:
- Lubuntu 18.04 (recent reinstallation due to confirmed hack) on a Dell XPS13 L321x.
- Internet connection via a) Android phone's hotspot (now), b) wireless 4G dongle (last fornight)
