I have an interface dev6273 on my laptop listed by ifconfig, which I am finding very difficult to get rid of. I don't understand why it persists, as there is no mention of "dev6273" anywhere in /etc, /var/lib or /var/run . [It is referred to in /sys and /proc , but I assume this arises from its existence rather than the other way round.] The interface was created about a month ago, when I was in a different country, and connected the laptop by ethernet to a router. It is mentioned quite often in /var/log/messages, always in connection with NetworkManager, eg ------------------------------- Oct 15 00:35:30 carrie NetworkManager: <info> dev6273: Device is fully-supported using driver 'tg3'. Oct 15 00:35:30 carrie NetworkManager: <info> Now managing wired Ethernet (802.3) device 'dev6273'. Oct 15 00:35:30 carrie NetworkManager: <info> Deactivating device dev6273. ------------------------------- It doesn't do any harm. I just wonder if it will ever go away ... ------------------------------- [tim@carrie ~]$ ifconfig dev6273 Link encap:Ethernet HWaddr 00:16:41:A7:C7:FC UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:18 ------------------------------- -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
