What is the loopback device and how do I use it? - Ask Ubuntu So there are a few other ways loopback is use in Ubuntu that should not be confused with the loopback device in networking Loop Mounts To mount a disk image in Ubuntu, you could run: sudo mount -o loop image iso media label This is usually called a loop device (and not a loopback device), but the term loopback file interface is occasionally
networking - What is the difference between Pinging loopback address . . . The two are on different "interfaces" - the lookback address is on the loopback interface which should be present always (unless you've done something really freaky with your config) The local IP address is on one of your other network interfaces If that interface didn't come up, then that ping will fail but the loopback IP should still work
Whats the default etc network interfaces? - Ask Ubuntu # The loopback network interface auto lo eth0 iface lo inet loopback # The primary network interface iface eth0 inet static address 192 168 10 33 netmask 255 255 255 0 broadcast 192 168 10 255 network 192 168 10 0 gateway 192 168 10 254 dns-nameservers 192 168 10 254
Grub command `loopback loop. . . ` does not work on Ubuntu 19. 10 loopback loop (hd0,gpt2) ubuntu-19 10-desktop-amd64 iso grub hangs, there is no more output or activity on the terminal, and eventually the laptop fans spin up because the laptop gets hot The path (hd0,gpt2) ubuntu-19 10-desktop-amd64 iso is valid on my system
Get the audio from Line-in to output to the speaker Try use the pulse audio: module-loopback, this module loops all incoming audio back through your outputs ,that isn’t enabled in Ubuntu by default # Manually start the module-loopback pactl load-module module-loopback # Configure your system to load module-loopback on startup
Additional IP address to loopback via etc network interfaces auto lo iface lo inet loopback iface lo inet static address 169 254 255 254 24 but it did not seem to have any effect So I hacked it as auto lo iface lo inet loopback post-up ip addr add 169 254 255 254 24 dev lo:0 pre-down ip addr del 169 254 255 254 24 dev lo:0 which works, but feels hacky
Port listening on localhost:8000 but not on ip:8000 - Ask Ubuntu As @JamesHenstridge points out, the behaviour you're observing is not due to Ubuntu blocking your application on some IPs, but due to your application explicitly binding only to the local loopback interface (127 x x x) At least if you didn't install and set up a firewall to specifically block that port
encryption - LUKS and loop device - Ask Ubuntu NOTES ON LOOPBACK DEVICE USE Cryptsetup is usually used directly on a block device (disk partition or LVM volume) However, if the device argument is a file, cryptsetup tries to allocate a loopback device and map it into this file
How to enable microphone loopback into headset - Ask Ubuntu pactl load-module module-loopback latency_msec=1 On the Recording tab of pavucontrol, you can show all streams (combobox at the bottom) and then configure which microphone (if you have more than one) should loopback into the built-in analog stereo To stop it running, run: pactl unload-module module-loopback
