10-7 Results Storage Area Response Codes

Response UNIX error
code message
0003 ESRCH
0006 ENXIO
0009 EBADF
000D EACCES
186
Probable cause
The same socket service is already in
progress at the specified socket number.
The specified socket is not open.
The internal buffers are full because there
is too much traffic at the local node,
preventing data from being sent.
IP address conversion failed.
IP address conversion is set for automatic
conversion only.
For network relay errors using SEND(090) or RECV(098), check the path of the
command using the routing tables and the nature of the error using the response
code to eliminate the cause of the error.
For network relay errors using CMND(490), the location of the relay error is re-
corded in the second through third words of the response, as shown below.

The response codes stored in the Results Storage Area can be used to trouble-
shoot socket service problems. Refer to 6-2 Using Socket Services with Socket
Service Request Switches or 6-3 Using Socket Services with CMND(490) for the
location of the response codes stored in the Results Storage Area.
The UNIX socket service error messages corresponding to the response codes
are given in the following table. Refer to the documentation for the devices in-
volved when communicating between an Ethernet Unit and other devices.
Description
No such process
No such device or address
Bad file number (incorrect socket
specification)
Permission denied
(Broadcast address specified for re-
mote IP address for active TCP
open)
Use the socket status flag in PC memory to be
sure that socket service has finished before
starting services again.
Open the socket. For TCP sockets, be sure to
wait until connection is made.
Correct the user application to reduce traffic at
the Ethernet Unit.
Check the IP address and subnet mask in the
System Setup and be sure that settings are
correct.
Check the mode settings in the System Setup.
This error will be generated for the READ IP
ADDRESS command only.
