I have just discovered that there might be a possible conflict in setting
some networking parameters when booting a RH system.
There exists a file /etc/sysconfig/network and in my case it contains:
NETWORKING=yes
FORWARD_IPV4=no <---------------------
HOSTNAME=hero.lannet.com.au
DOMAINNAME=lannet.com.au
GATEWAY=203.41.237.73
GATEWAYDEV=eth0
There is also a file /etc/sysctl.conf and in my case it contains:
# Disables packet forwarding
net.ipv4.ip_forward=0 <----------------------
# Enables source route verification
net.ipv4.conf.all.rp_filter = 1
# Disables automatic defragmentation (needed for masquerading, LVS)
net.ipv4.ip_always_defrag = 0
# Enable the magic-sysrq key
kernel.sysrq = 1
# Disable tcp_timestamp
net.ipv4.tcp_timestamp = 0
# Enable tcp_syncookies
net.ipv4.tcp_syncookies= 1
Notice how the ip_forward flag is referred to in both files. What if they
are set in conflict, which one will get the guernsey?
