Not having 1.3 available I can only use 4.3 as a start. The command:
netstat -r should list your routing tables. I don't know if 1.3 has SMIT or its equivalent but there should be some way to add a default gateway which is your router.

Thanks for reply

My copy of AIX 1.3 does not have SMIT or equivalent, just pure command line.
#netstat -r
DESTINATION GATEWAY FLGS REFCNT USE INTERFACE
localhost localhost UH 0 0 lo0
192.168 aixps2 U 2 13 wd0

Machine is actually 192.168.0.25 with a host name of aixps2.
wd0 is the Western Digital NIC.

Will search on how to set up a default gateway

Basil
Found out how to set up a default gateway in AIX 4 and applied it to AIX 1.3

#/etc/route add 192.168.0.1 aixps2 0
Screen said the command activated okay but still cannot ping ISP.


Looking at the /etc/rc.net file I see that the command to add a gateway is: route add 1.2.3.4 gateway
Does this work?
Otherwise you might want to look at the /etc/rc.net and rc.tcpip files to see if there are any hints in the comments.

Is my interpretation of the AIX 1.3 #man route correct ?

DESCRIPTION

The route command is used to manually manipulate the network routing

tables.
It normally is not needed, as the system routing table management

daemon,
routed, tends to this task.

The route command accepts two commands: add, to add a route, and

delete, to
delete a route. In addition the route command accepts the following
parameters:

destination
Is the destination host or network.

gateway
Is the next-hop gateway to which packets should be addressed.

metric
Is a count indicating the number of hops to the destination.

The metric is required for add commands. It must be zero if the

destination is
on a directly-attached network, and nonzero if the route utilizes one

or more
gateways. If adding a route with metric 0, the gateway given is the

address of
this host on the common network, indicating the interface to be used

for
transmission. Routes to a particular host are distinguished from

those to a
network by interpreting the Internet address associated with

destination.

The optional keywords net and host force the destination to be

interpreted as a
network or a host, respectively. Otherwise, if the destination has a

local

address part of INADDR_ANY, or if the destination is the symbolic name

of a
network, then the route is assumed to be to a network. It is presumed

to be a
route to a host. If the route is to a destination connected via a

gateway, the
metric should be greater than 0. All symbolic names specified for a
destination or gateway are looked up first as a host name using

gethostbyname.
If this lookup fails, getnetbyname is then used to interpret the name

as that
of a network.

The optional keyword default may be substituted for the destination

parameter.
This causes the gateway specified as the next parameter to be treated

as the
default exit point for the network. This "default gateway" will be

used for
any packet with an unrecognized address. This provides a place for

packets to
be sent when the host handling the packet can not find the Internet

address in
its own route table. A "default" gateway" is very useful; it is

often
specified when there are hosts in the network that are not running

routed.

The route command uses a raw socket and the SIOCADDRT and SIOCDELRT

ioctl's to
do its work. As such, only the superuser may modify the routing

tables.

FLAGS

The route command options are:

-f Flushes the routing tables of all gateway entries. If this is

used in
conjunction with one of the commands described above, the

tables are
flushed prior to the command's application.

-n Prevents attempts to print host and network names symbolically

when
reporting actions.

EXAMPLES

# /etc/route add newnet thishost 3

# /etc/route delete newnet thishost

MESSAGES

add [ host | network ] destination gateway

Explanation: The specified route is being added to the tables. The

values
printed are from the routing table entry supplied in the ioctl call.

If the
gateway address used was not the primary address of the gateway (the

first one
returned by gethostbyname), the gateway address is printed numerically

as well
as symbolically.

delete [ host | network ] destination gateway

Explanation: As above, but when deleting an entry.

Flushing routing tables: destination gateway

Explanation: When the -f flag is specified, each routing table entry

deleted
is indicated with a message of this form.

network is unreachable

Explanation: An attempt to add a route failed because the gateway

listed was
not on a directly-connected network. The next-hop gateway must be

given.

not in table

Explanation: A delete operation was attempted for an entry which

wasn't
present in the tables.

routing table overflow

Explanation: An add operation was attempted, but the system was low

on
resources and was unable to allocate memory to create the new entry.
