Error with getting interface flags
Vodicka 15 comments, this article is step-by-step tutorial how to fix a problem which occured after, i restored my virtual machines from backup to my, eSXI server. If you don't use the correct interface name, then it won't work.
BCM2046B1 USB.0 Hub (part of BCM2046 Bluetooth) Bus 003 Device 001: ID 1d6b:0001 Linux Foundation.1 root hub # pcmcia card info # # rfkill # # lsmod # wmi 20480 0 # interfaces # auto. # module infos # # module parameters # # /etc/modules # lp rtc # modprobe options # /etc/nf blacklist ath_pci /etc/nf blacklist b43 blacklist b43legacy blacklist ssb blacklist bcm43xx blacklist brcm80211 blacklist brcmfmac blacklist brcmsmac blacklist bcma /etc/nf blacklist evbug blacklist. My arch system is configured to give older interface names, but the newer names (automatically configured by ubuntu) give newer (more complicated, harder to remember, and type) information.
attraddress" MAC address attrdev_id"0x0 attrtype"1 kernel"wlan name"wlan0" # dmesg #.554383 wl: module license 'mixed/Proprietary' taints kernel. ALL the commands work fine except the last command. Eth0 Interface doesn't support scanning. So, I found my network adapter.
attraddress" MAC 'enp0s25' IF1 attrdev_id"0x0 attrtype"1 kernel"eth name"eth0" # PCI device 0x14e4:0x432b (wl) subsystem"net action"add drivers"? Man ifconfig then, afterwards, you'll understand what ifconfig does.
Ifconfig ifconfig when eth0 is not available when, i used lspci, result was lspci lspci result, so network adapter is correctly available in my virtual machine.

You might want to do some googling on some basic networking commands and how they work.
The Ubuntu Server Guide has some detailed information on how to accomplish configuration, bringing the interface down, and back.

As next step I need to found out which alias is used for this adapter. Wireless 365 Bluetooth Bus 003 Device 004: ID 413c:8162 Dell Computer Corp. Linux Linux network virtual-machine.

Lo Interface doesn't support scanning. Modprobe: error: could not insert 'wl Unknown symbol in module, or unknown parameter (see dmesg) update-initramfs: deferring update (trigger activated) Processing triggers for initramfs-tools (0.103ubuntu4.9).
I didnt find any easily way than try et0,eth1.

Diff between built and installed module!)

Sudo ip link set eth0 up will bring the interface up if it was down. Ip address will also display similar information. Now as last step its necessary to update network interfaces to this adapter sudo nano /etc/network/interfaces #and change all eth0 to eth1 values /etc/network/interfaces As last step restart your machine and everything should work correctly.
DNS (a.b.c.d is your, iP address or, if you're using, dHCP: device'enp2s0' typeethernet bootprotodhcp onboot'yes' NM_controlled'yes' Once you've checked/edited the file above, restart networking with: systemctl restart rvice). Also, ifconfig is considered to be a deprecated tool (i still use it however, it's handy because it's familiar and easy to use).
