I'm seeing weird errors trying to add a route:
[Stone - root] 242> route add default 10.1.1.2
writing to routing socket: Network is unreachable
add net default: gateway 10.1.1.2: Network is unreachable
This is weird because...
[Stone - root] 243> ifconfig tun0
tun0: flags=43<UP,BROADCAST,RUNNING> mtu 1000
inet 10.1.1.1 netmask 0xfffffffc broadcast 10.1.1.3
and "netstat -rn" prints, among others, a line
10.1.1/30 10.1.1.1 U 0 0 1000 tun0
So the question is, what am I missing? I've been trying to follow the
code paths, and so far haven't found any reason why this attempt would
fail. For what it's worth, if I have "route monitor" running when I do
the "route add", I get
got message of size 112 on Sun Nov 21 03:46:04 1999
RTM_ADD: Add Route: len 112, pid: 3174, seq 1, errno 51, flags:<UP,GATEWAY,STATIC>
default 10.1.1.2 default
I suppose I could just add debugging code all through the code path
followed by "route add", but that would be a mess, not to mention
rather tedious to do.
The kernel calls itself "1.4J"; it's built from the sup of 1999-08-13.
Could this plausibly be something that would be fixed by upgrading to
-current instead? I'd rather avoid that if possible. The hardware is
a SPARC IPX, not that I expect that to matter. The only patch I have
that goes anywhere near routing code is a fix to ip_rtaddr (ip_input.c)
to keep it from cacheing stale routes indefinitely - and I don't think
ip_rtaddr is involved here.
