In Linux, you can rename your interfaces with nameif tool. This is a very useful feature for boxes containing more than one interfaces. But after renamed an interface ethtool does not accept. Example: root@medeia> cat /etc/mactab internet 00:C0:DF:14:22:1F home 00:01:02:0B:B2:E6 root@medeia> ifconfig home home Link encap:Ethernet HWaddr 00:01:02:0B:B2:E6 inet addr:172.16.36.254 Bcast:172.16.36.255 Mask:255.255.255.0 UP BROADCAST RUNNING 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:5 Base address:0xc400 root@medeia> ethtool home home does not appear to be an ethernet device ethtool version 1.8 Usage: [...] root@medeia> ethtool eth0 Settings for eth0: Cannot get device settings: No such device Cannot get wake-on-lan settings: No such device Cannot get message level: No such device Cannot get link status: No such device No data available root@medeia> ethtool eth1 Settings for eth1: Cannot get device settings: No such device Cannot get wake-on-lan settings: No such device Cannot get message level: No such device Cannot get link status: No such device No data available Reproducible: Always Steps to Reproduce: 1.rename the eth0 interface with nameif command (for example to home) 2.try to use ethtool on it. Actual Results: root@medeia> ethtool home home does not appear to be an ethernet device ethtool version 1.8 Usage: [...] root@medeia> ethtool eth0 Settings for eth0: Cannot get device settings: No such device Cannot get wake-on-lan settings: No such device Cannot get message level: No such device Cannot get link status: No such device No data available Expected Results: List of the settings of the ethernet device "home"
just added ethtool-3 which seemed to work for me ... renamed eth1 to 'blah' and then ran `ethtool blah` and it worked
