Topic: SME Server 7.4 on VMware Server 2.0 - can't access server manager

[Marco Hess]

A while ago now I moved my SME7 server to a new hardware platform. At that time I had trouble with the networking of VMware guests.

Some of these problems are discussed here  http://bugs.contribs.org/show_bug.cgi?id=5730.

After A lot of trial and error I could solve it by switching off the offloading options in the ethernet driver as follows:

Code: [Select]

/usr/sbin/ethtool -K eth0 sg off rx off tx off tso off
So it may be worthwile to try this and see if it fixes it.

To make this fix permanent, I ended up with a small script that is run at startup:

Code: [Select]

#!/bin/sh
#
# This script disables the offloading options for the eth0 driver as these
# options enabled cause problems with the the network connections on VMware guests.
# See also http://bugs.contribs.org/show_bug.cgi?id=5730

ETHTOOL="/usr/sbin/ethtool"
DEV="eth0"
OFFLOAD_OPTIONS="sg off rx off tx off tso off"
case "$1" in
  start)
    echo -n "Disabling eth0 offloading options to fix VMware networking bug  ...";
    $ETHTOOL -K $DEV $OFFLOAD_OPTIONS;
    echo " done.";;
  stop)
