Hi aexl, In order for the ethtool command to work, you need root privileges. Try using sudo:
$ sudo ethtool -K eth0 tso off That should work. BUT: the more recent patched kernels from Ubuntu do not have that problem anymore (at least for me). If you make sure your system is up to date with the latest fixes, the problem should go away without needing to use the ethtool fix. Try a full update first. If it still doesn't work, then try the ethtool fix. Beyond that, I'm not sure what you could do... -- VMWare networking extremely slow https://launchpad.net/bugs/51363 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
