Hi,
I'm just doing some tests where to use an ubuntu machine as a router
and thus plugging in an USB Ethernet devices as it's second ethernet
interfaces.
Unfortunately I can't keep that damned Network manager from renaming
the device (i.e. from eth0 to enxe80006d8), even if I tell NM to
ignore the device. Since this happens before udev, it confuses several
udev scripts).

[Touch-packages] [Bug 1535648] Re: ifquery crashing
I've found two problems: 1.) See /lib/systemd/system/ifup-wait-all-auto.service the line for i in $(ifquery --list --exclude lo --allow auto); do INTERFACES="$INTERFACES$i "; done; There is a space missing in "$INTERFACES$i " it concatenates all device names into one 2.) This ifquery-call just crashes: # ifquery --state vlan0 Segmentation fault (core dumped) # ifquery --state lo Segmentation fault (core dumped) for some reason it does not crash with eth0 # ifquery --state eth0 So please fix ifquery. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ifupdown in Ubuntu. https://bugs.launchpad.net/bugs/1535648 Title: ifquery crashing Status in ifupdown package in Ubuntu: New Bug description: Hi, I'm just doing some tests where to use an ubuntu machine as a router and thus plugging in an USB Ethernet devices as it's second ethernet interfaces.
