</div>But don't do it if it hurts :)<br></blockquote><div><font color="#888888">Dejan</font> <br></div><div>Thanks a lot for your reply Dejan and Lars,<br>Actually I just restarted network using the command<br><br>"# /etc/init.d/network restart"<br>
<br>And its taking a bit of time, may be 40 sec for restarting network and ntp.. And I am not doing a kind of "ifdown eth0"..
