[lugs] Pinging shows unknown host<BR><BR></FONT></DIV>
<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT color=#0000ff face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm connecting to a network with the domain
name test.com. My PCs with the windows OS (hostname is pc1 and pc2) could
ping each other with their hostname or hostname with domain name. I
installed Redhat 7.2 on another system and change the hostname to pc3 by
modifying the /etc/hosts and /etc/sysconfig/network files and restarting the
PC (another other elegant way to change the hostname using a system command?
did I miss out any other files?).</FONT></DIV>
<DIV><FONT face=Arial size=2>pc3 could ping pc1 and pc2, but pc1 and pc2
couldn't ping pc3, and shows the unknown host msg. When I type domainname in
pc3, it shows none. Therefore, I run domainname test.com on pc3 to set the
domainname (is this necessary? I believe so. What files are changed by this
command?). I still couldn't ping pc3 from my windows or other linux systems.
Could someone help me with this? Thank you.</FONT></DIV>
