Subject says it all-- I'm having trouble getting fc3 configured, & can't get packets into or out of the box. It does answer pings from other nodes, and 'ifconfig eth0' looks right.
"Network is unreachable" is one of several hundred standard errors encountered by any application.
Any application can report this error message.
Check your routing table, run the 'route' command.
Possible reasons:
â Your default route is not set.
â Your netmask is wrong. ifconfig may look right, but the netmask setting is frequently overlooked or ignored. If you do not explicitly specify a netmask for an network interface, a default one will be picked based on old A/B/C classes, which may not necessarily be right, in this day and age.
