You said that you entered the ethernet address that was listed on the back of the card. I just installed 2 ODT systems using the WD8003 also, and nowhere did I enter the ethernet address, instead I entered a IP address ie: 129.126.55.28 which was automatically put into a file called /etc/tcp, which starts up tcp/ip on boot up. You also need to enter your IP address in /etc/hosts as well as those for the systems that you wish to reach ie: 127.0.0.1 localhost local 129.126.55.28 brandon <-------------------local system 129.126.12.158 brandy When the system comes up then you should be able to ping the remote system. If this information is not there or incorrect (ie: your IP address does not match your machine name), you can still ping localhost and yourself, but you will not get out onto the wire. You also mentioned that you just ran thinwire ethernet (RG-58 50 ohm cable with BNC connectors) between your 2 machines, did you put a terminator at each end? If not your WILL have problems. Forgive me if this has already been done on your system. I am NOT an ethernet expert, but I have put together about 20 systems of various types and connected them with TCP and NFS and struggled through the configuration and setup. -- ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ | Mark Hilliard, N2HHR | AWK is not just a | | Fax 315-986-5882 | LANGUAGE | | mark@gizzmo.kodak.com | It is a way of LIFE! |

I'm trying to set up a TCP/IP "network", but I've got rather stuck.
I am using SCO UNIX 3.2.2 and SCO TCP/IP Version 1.1.1. Hardware is Western
Digital WD8003 Ethercard Elite ethernet cards (1x16bit and 1x8bit).
At the moment, all I want to do is be able to TELNET into the UNIX system
from my PC.
So far, I have installed the 16-bit WD card in the UNIX system and the
8-bit one in the PC, and have joined them together with some 'cheapernet'
cable. The DOS-based diagnostic utilities supplied with the cards work and
show that packets sent by one card are received OK by the other.
The UNIX installation has been completed successfully using mkdev wd and
mkdev tcp. When I was asked to enter the Internet address of the ethernet
card, I entered the 'network address' number which was on a label on the
back of the card. I've been able to 'ping localhost' and TELNET to myself
with no problems.
The difficulties I've been having relate to getting the PC connecting to
the UNIX system. I've got CUTCP V2.2 (Clarkson University's version of NCSA
Telnet).
It seems to be setup OK (when I use the loopback address, 127.0.0.1, what I
type is echoed correctly). However, when I try setting up a connection to
the UNIX system using TELBIN (I type ALT-A and then enter its network
address), CUTCP puts up the trying to connect message, and then quickly
clears the screen and goes into 'session' mode where presumably I should
get a login prompt. However, nothing is displayed -- even if I type RETURN
several times.
After about 30 seconds, the screen clears again and the program exits.
The odd thing is that after I've tried to connect from the PC, if go to the
UNIX system and run a netstat -A (which shows the addresses of 'protocol
control blocks'), an entry is displayed for each attempt I have made to
connect from the PC. The entries stay on the list for about 5-10mins. Here
is an example:
$ netstat -A
Active Internet connections
PCB Proto Recv-Q Send-Q Local Address Foreign Address (state)
d1108a04 tcp 0 0 morag.telnet 192.1.164.48.7183 SYN_RCVD
d1108a84 tcp 0 0 morag.telnet 192.1.164.48.6643 SYN_RCVD
d1108c84 tcp 0 0 morag.telnet 192.1.164.48.3638 SYN_RCVD
d1108d84 tcp 0 0 morag.telnet 192.1.164.48.3048 SYN_RCVD
$
Finally, when I put TELBIN.EXE in server mode and try to 'ping' it (using
ping followed by the network address) from the UNIX system I get
the error:
ping: send: Network is unreachable
Now, my questions:
Does anyone know what the SYN_RCVD means?
Should I have put details of the PC (network address or..?) in any of the
tcp/ip config files on the UNIX system?
Are the network addresses printed on the ethernet cards the same
as the IP addresses? If not, how (or where) should I map one to
the other?
Does anyone have any ideas as to why this setup might not be working?
Can anyone give any pointers as to how I should proceed?
As the answers to these questions may be fairly specific, please
reply by mail, and I'll summaries to anyone else who is
interested.
Thanks.
