1.0 INTRODUCTION
This HOWTO describes the steps to follow when configuring LU6.2
sessions to execute the sample 'sendto' and 'rcvfrom' code found
in the /usr/lpp/sna/samples directory. This code will transfer a
file between two RISC System/6000's running SNA Services/6000.
Token-Ring is used for the physical connection between the
two systems.
This HOWTO assumes the user is familiar with the System Management
Interface Tool (SMIT) and that SNA Services/6000 has been installed.
It is also assumed the token-ring adapter has been installed and its
data link device defined. This HOWTO was tested with AIX version 3.2.5
and SNA Services/6000 version 1.2.101.315.

2.0 CONFIGURATION CHECKLIST
The steps to configure SNA Services/6000 and LU6.2 sessions to
support the sample file transfer programs (sendto.c and rcvfrom.c)
supplied with the SNA Services code are described below. The RISC
System/6000 configured to receive files will be referred to as the
"Receive Host". The RISC System/6000 configured to send files will
be referred to as the "Send Host".
Step 1 - Login as 'root' user.
Step 2 - Compile the sample programs "sendto.c" and "rcvfrom.c".
These are found in the directory /usr/lpp/sna/samples.
Compile with the following commands:
cd /usr/lpp/sna/samples
cc sendto.c -o /bin/sendto -l sna
cc rcvfrom.c -o /bin/rcvfrom -l sna
Step 3 - On the Receive Host, run 'netstat -v' and record the
Hardware Address here for future use _____________________
(ie. 10:00:5a:a8:6d:ec should be listed as 10005AA86DEC)
Step 4 - Configure the SNA profile definitions necessary to
link the two RISC System/6000's over a Token-Ring attachment
using SMIT's Quick Configuration option for LU6.2.
Step 5 - Update additional SNA profiles as noted below.
Step 6 - Start SNA on both machines:
startsrc -s sna
Step 7 - On the Receive Host, start the sna connection:
startsrc -t connection -o REC_LU6
Step 8 - On the Send Host, start the sna attachment:
startsrc -t attachment -o SEND_LU6
Step 9 - Check to see if everything became active:
lssrc -ls sna
On the Receive Host you should see:
"sna" Program, Process ID xxxx
REC_LU6 Attachment - active
REC_LU6 Connection - active
Step 10 - To send a file from the Send Host to the Receive Host:
sendto SEND_LU6

3.1 DETAILED SMIT SCREENS FROM STEPS 4 & 5 FOR RECEIVE HOST
>> On the Receive Host, use the following SMIT fastpath:
smit _snaqc

Quickly Configure an LU6.2 Connection
Type or select a value for the entry field.
Press Enter AFTER making all desired changes.
-Entry Fields-
* Quick Configuration NAME (maximum 12 characters) -REC_LU6-
-------------------------------------------------------------------------

Quickly Configure an LU6.2 Connection: New Attachment
Type or select a value for the entry field.
Press Enter AFTER making all desired changes.
-Entry Fields-
* Select a default network ATTACHMENT type from the token_ring_listen
list.

Quickly Configure an LU6.2 Connection: Information
Type or select values in entry fields.
Press Enter AFTER making all desired changes.
-Entry Fields-
Quick Configuration NAME REC_LU6
-------------------------------------------------
Fully qualified LOCAL LU name -NET.REC-
Local LU ADDRESS (1-255 0=Independent LU) -0-
If Local LU Address is specified (other than 0),

-------------------------------------------------
Fully qualified REMOTE LU name -NET.SEND-
Remote Transaction Program (RTP) name -rcvfrom-
-------------------------------------------------
ATTACHMENT token_ring_listen
-------------------------------------------------------------------------

>>
1. Enter the fully qualified LOCAL LU name. The LOCAL LU name must match
the
the REMOTE LU name of the Send Host.
2. Enter MDEFAULT for MODE name. (MDEFAULT is used for convenience only).
Note: The MODE name must match on both Send and Receive Hosts.
3. Enter /bin/rcvfrom for Local TP name.
This needs to match the target executable program (compiled in Step
2).
4. Enter REMOTE LU name. The REMOTE LU name must match
the LOCAL LU name of the Send Host.
Note: In the fully qualified LU names above, NET is a Network name.
Allocation 112 errors occur when this is left off.

4.0 ERROR RESOLUTION
If you get the following errors, follow the listed Action described
below.
0513-056 Timeout waiting for command response.
Action: Make sure SNA services is started and try again.
0105-732 The datalink device for attachment "REC_LU6" is invalid.
Action: Add SEND as LOCAL LINK name in Token Ring Physical Link Profile
0105-734 The profiles for attachment "SEND_LU6" have an invalid
value. Check the local link name in the physical link profile.
Action: Add REC as LOCAL LINK name in Token Ring Physical Link Profile
0105-920 Start attachment cannot find the specified remote station.
Action: Make sure SNA services is started and try again.
allocate failed, errno = 112
Action: This is returned from the sendto program. Check to make sure that
the LU names (entered in the Quick Configure Screens above) are fully
qualified. They need to contain a network name or else a period is
prefixed onto the rest of the name, which is unexpected and usually
creates this problem. Otherwise you may have a typo in one of your LU
names.
