Managing SNAplus2 Clients
Client Networking Requirements
Client Networking Requirements
Before you can run SNAplus2 on a client computer, you must configure
TCP/IP port addresses on both the clients and servers in your network. If
you encounter problems with the default port assignments, you may
need to resolve conflicts as described in “Setting Up IP Port Numbers”.
In addition, you may wish to set clients up so that the TCP/IP connection
is dropped automatically when the client is finished using SNAplus2, as
described in “LAN Access Timeout”.
Setting Up IP Port Numbers
SNAplus2 uses both TCP/IP and UDP/IP communications to send
client/server data across the LAN. By default, it uses the port number
1553
for both types of communications. For most installations, this port
number should be suitable; you do not need to change it.
If you encounter problems enabling the SNAplus2 software, check the
error log file for messages indicating that the port number used by
SNAplus2 clashes with the port number used by another program. If you
find such messages, take the following steps:
Step 1. Check the
/etc/services
file on the computer where the error
occurred, to see if another program is listed as using the port number
1553
for either TCP/IP or UDP/IP communications. If this is the case,
first try to change the other program to use a different port.
Step 2. If you cannot do this, or if no program is listed as using port 1553, find
another port number that is not listed in the file as being used by any
program. Check the
/etc/services
file on all other SNAplus2
computers in the same domain, to ensure that the number is not used on
any other computer.
Step 3. In the
/etc/services
file on each computer in the domain, add two
lines in the following form:
sna-cs
nnnn
/tcp
sna-cs
nnnn
/udp
The nnnn entry is the new port number. This must be set to the same
value on all computers in the SNAplus2 domain.
