Testing a Client Connection

Client applications communicate with ACSLS over TCP/IP using the RPC (remote procedure call) protocol. If a client system cannot communicate with ACSLS, you can use rpcinfo to test whether ACSLS is reachable from the client machine.

From the ACSLS server, verify that ACSLS is running.
```
psacs
```
From the ACSLS server, verify that the RPC daemon is running.
```
ps -ef | grep rpc
```
From the ACSLS server, verify that program number 300031 is registered for TCP and IDP.
```
rpcinfo | grep 300031
```
This program number confirms that ACSLS is running and that ACSLS has registered with RPC.
From the client machine, or any UNIX machine on the network, use rpcinfo to exchange a packet with program number 300031 on the ACSLS server.
Specify the IP address of the ACSLS server along with the program number.
```
rpcinfo -t <ip address> 300031
```
If the communication exchange was successful, the rpcinfo utility will display the following message:

program 300031 version 1 ready and waiting

program 300031 version 2 ready and waiting

This confirms that ACSLS is available for client connections across the network.
