Description Vince Hoang 2004-10-22 20:10:01 UTC 
Description of problem:

In the lab, the instructions tell you to make changes to your
interfaces earlier in the steps than enabling ip_forwarding. The
result is `service network restart` sometimes does not complete, and
/etc/resolv.conf gets overwritten, since the client workstations are
configured for DHCP.

I would suggest changing the order so that ip_forwarding should be
done BEFORE modifying interfaces to avoid confusion.

Version-Release number of selected component (if applicable):
2.1

How reproducible:
Always

Steps to Reproduce:
1. Walk through lab objectives in the order described
  
Additional info:

The curriculum recommends restarting the network to enable
ip_forwarding. It should be noted that ip_forwarding will NOT be
enabled unless /proc/sys/net/ipv4/ip_forward is modified, either
directly or by restarting the network. Mentioning
/proc/sys/net/ipv4/ip_forward is also good, because it provides a
means to check that ip_forwarding is enabled, rather than having to
inaccurately rely on /etc/sysctl.conf being updated.

not sure i fully understand lab issue, but change in ordring is simple
enough... done.

had wanted to avoid /proc filesystem, but went ahead and added an 
"under the hood" note to the curriculum to imply if /proc not yet
fully understood, it's not that big of an issue.
