I use USB Gigabit adapter based on RTL8153. So far it worked OK but I have found today that I cannot configure alias with ifconfig. Try to configure alias IP address with ifconfig changes default interface. It looks like a bug in the RTL8153 driver. $ ethtool -i enx00e04c68002f driver: r8152 version: v1.12.13 firmware-version: rtl8153b-2 v1 10/23/19 expansion-rom-version: bus-info: usb-0000:00:14.0-2 supports-statistics: yes supports-test: no supports-eeprom-access: no supports-register-dump: no supports-priv-flags: no $ lsusb | grep 8153 Bus 002 Device 004: ID 0bda:8153 Realtek Semiconductor Corp. RTL8153 Gigabit Ethernet Adapter Steps to replicate: 1) Connect USB adapter to a LAN, I assume I received IP address 192.168.1.11 from DHCP server. 2) check with ifconfig what is IP address on interface enx00e04c68002f 3) define alias, 'sudo ifconfig enx00e04c68002f:33 192.168.33.11' 4) check with ifconfig the result I see that there is no new interface enx00e04c68002f:33 and that IP address on interface enx00e04c68002f was changed to 192.168.33.11. That is a bug! Expected behavior: Interface enx00e04c68002f will keep IP address assigned from DHCP server, like 192.168.1.11 New interface enx00e04c68002f:33 will be added with IP address 192.168.33.11 This report is for an older kernel and older Ubuntu distribution. I assume the bug is still in the newer kernel, this has to be retested... --- When I use this method on my WiFi interface (based on rtl8821ce), IP alias works as expected. This points to an issue with r8152 driver... --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.27 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: psl 196710 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: X-Cinnamon DistroRelease: Linux Mint 20.3 InstallationDate: Installed on 2022-04-12 (1043 days ago) InstallationMedia: Linux Mint 20.3 "Una" - Release amd64 20220104 MachineType: ASUSTeK COMPUTER INC.
