NETWORK CONNECTION

[johny2K]

aix/perts,

can anybody help me pin-point what i've missed re connecting to Internet?

i'm using AIX 4.3.3 on a powerserver with BNC port and trying to connect it to my cable connection. from a cable modem, i attached a hub with bnc port. at the back of my powerserver, after connecting it to the port - i terminated the other end of the BNC connector by a ethernet terminator (50 OHM).

1. lsdev -Cc adapter shows:
:
ent0 Available 00-02 Ethernet High-Performance LAN Adapter (8ef5)

2. two network interfaces:

en0 Standard Ethernet Network Interface
et0 IEEE 802.3 Ethernet Network Interface

3. can ping localhost

4. no errpt

i want it to pick-up an Internet connection same as my Linux server (on the same hub).

do i really need some info from my internet cable provider re default gateway or DNS? or i can pick it up from my linux server. cable provider doesn't usually give you these things, specially if you are not using Microsoft.

thank you - in advance.

you will need to do the following:

cp /etc/nsswitch.dns /etc/nsswitch.conf
vi /etc/resolv.conf and add the nameserver (your ISP dns) entry into it.
vi /etc/defaultrouter and add the Cable Modem internal IP address.

You should be good from there.

Did you attach IP configuration to the interface? I mean en0. You can try:

ifconfig en0

It should show the interface UP and having a correct IP/netmask, etc. If it does not, you shoud run
smit mktcpip
to set up ip to the interface.
Another case if the interface is running well on the LAN but does not "see" the internet outside.
Which one is your case?

BNC connections need to be terminated on BOTH ends. You should have a BNC "Tee" connected to both the RS6K and the hub with the connecting cable connected to one side of the "Tee" and a 50 ohm terminator on the other side of EACH "Tee".

If you haven't done that already, give it a try.

and don't forget the other items mentioned in the other responses either.

thank you aix/perts,

it's working now!!!

first, for comtec17 - i tried what you recommended to do, but i don't have the following file:

/etc/nsswitch.dns (i have /usr/include/nsl/nsswitch.h)

instead i added the second nameserver under /etc/resolv.conf and added the Cable Modem internal IP address (smit tcpip) together with the subnet mask as mentioned by trifo with reference to my Linux server.

what matter most eventually is by terminating each "Tee" connection with a 50 ohm ethernet terminator. coz as i tried to connect without it, i got nothing and seems it hanged but when you check the hub (LEDs), it keeps on blinking.

again, thanks to everyone.
