How to connect to Home LAN

[ssukjir]

Hello,

Just bought a RS/6000 43P-150 and I am quite new on AIX. I wonder if anyone have configured AIX with Cable Modem. I have a simple router D-Link 640 at home, which now links my Thinkpad (Win2000) to Roadrunner. I would like to do the same thing with RS/6000 or at least have my notebook connected to the RS/6000 server though the router. However, still can't find a way to configure.

-- I connected a twisted pair cable between the RS/6K and my router. The problem was, after starteding AIX (4330-11), I did not see a green light lid up on router, as usually does when I connect my notebook with the router. Is there a way I can find out if something wrong with my network set up? or if my router doesnot support AIX?

I tried to diagnose the problem with follows:
-- lsdev -Cc adapter shows 10/100 Ethernet PCI Adapter available
-- lslpp -l devices.pci.23100020.* shows device driver are installed
-- I did smit inet and changed current STATE for en0 to UP to start the ethernet interface
-- lsdev -Cc if shows both en0 and lo0 are available.
-- I did setup TCPIP and use Automatic configure TCPIP using DHCP. Then reboot the machine.
-- After reboot, the RS/6K still can't connect to router.

Any suggestion or if you have a step by step would be very appreciated.

hi,
divide th problems : hardware, software, ecc

1st
after 150 has booted, the nic ( I belive you are
using that in mother board) is hw activated.
Then if you connect a right cable between

Computer <-> NetworkDevice (Hob,switch,router...)

you have to see the connection led go ON.

You speack of twisted-pair-cable: I hope you mean a
CAT5 cable as that of PC : for simply, all 8 wire
connected, in stright mode ( 1-1 .. 8-8 )
(For a test, detach the cable from PC and connect
this to RISC)

If the hw is ok, test the SW: continue by DHCP, but
if it does not go, see following

using
ifconfig -a
(you can see what address has your nic )

try to config manually the risc (always for test: the best
is to leave boxes do their job):


switch-off dchp client, reboot, smitty mktcpip

to choose ip-parameters, go at pc end enter in a command prompt window the

ipconfig /all

from the output note :

PC ip-adress
Network Mask
Default gateway

Go at the smit panel and put same mask and def-gateway

For ip-adress, choose an one that differs just in the last
octet

eg:

PCadr : 192.168.1.20
DG : 192.168.1.250
netmask : 255.255.255.0

choose

RISC-addr : 192.168.1.21

or (detach PC or shutdown, and use the same, always for test)


Probably my help does not resolve your problem, but
you could understand better where it is located.

all the best

ciao, Vittorio

i got the same problem but fixed now.

1. usually internet cable provider provide 2 IPs which when you connect your PC (or say MS system) to the modem cable or hub/router connected to the cable modem - will connect automatically.

2. for AIX-RS/6K, check your:

/etc/resolv.conf for the name_server,
/etc/hosts,
/the subnet_mask, etc.

in short, once you fill up parameters under smit tcpip, it should be fine.

goodluck...
