5. Error Codes

Error codes and error names associated with messages displayed on UNIX hosts are listed here. Some of these messages are also generated by MultiNet.

The below table lists the error codes alphabetically.

Error Name	Error Code	Description
E2BIG	7	Arg list too long
EACCES	13	Permission denied
EADDRINUSE	48	Address already in use
EADDRNOTAVAIL	49	Can't assign requested address
EAFNOSUPPORT	47	Address family not supported by protocol family
EAGAIN	11	No more processes
EALREADY	37	Operation already in progress
EBADF	9	Bad file number
EBUSY	16	Mount device busy
ECHILD	10	No children
ECONNABORTED	53	Software caused connection abort
ECONNREFUSED	61	Connection refused. This can occur when a connection is attempted to a non-existent server process. This message indicates that even though a path was established to the remote host, the remote host is not prepared for the type of connection attempted. Therefore, the connection was refused. The most likely cause is that a server (daemon) has not been enabled on the remote host. Servers are enabled automatically when a host is booted. Check with the system administrator of the remote host.
ECONNRESET	54	The connection was reset by the remote node. This occurs when the remote node has rebooted and the local node attempts to transmit on a stale connection.
EDEADLK	35	Operation would block
EDESTADDRREQ	39	Destination address required
EDOM	33	Argument too large
EDQUOT	69	Disc quota exceeded
EEXIST	17	File exists
EFAULT	14	Bad address
EFBIG	27	File too large
EHOSTDOWN	64	Host is down
EHOSTUNREACH	65	No route can be found to the host you are trying to contact, an intermediate router is not working temporarily, or an intermediate router is set to prevent access to the host. If you are attempting to access a remote host via modem, this error means the terminal port is set /MODEM but no modem carrier (DTR) is present.
EINPROGRESS	36	Operation now in progress
EINTR	4	Interrupted system call
EINVAL	22	Invalid argument
EIO	5	I/O error
EISCONN	56	Socket is already connected
EISDIR	21	Is a directory
ELOOP	62	Too many levels of symbolic links
EMFILE	24	Too many open files
EMLINK	31	Too many links
EMSGSIZE	40	Message too long
ENAMETOOLONG	63	File name too long
ENETDOWN	50	Network is down
ENETRESET	52	Network dropped connection on reset
ENETUNREACH	51	Network is unreachable. The IP network you are trying to contact is not reachable. No route to the remote host or network can be found. This can be due to one of the following conditions: · Two hosts on the same network were assigned Internet addresses containing different network numbers. · The remote host is on a different network but you have not added the proper route entry using the MULTINET SET/ROUTE command. If you have a single gateway available, you can set a DEFAULT ROUTE to send all packets to this gateway. · If your network is a Class C network (that is, the first byte of the network is 192 or larger), make sure the first three bytes of the Internet address are the same for all hosts. To correct these problems, check the routing tables and HOSTS files to resolve the incompatibility, and make sure the hosts have the same network number.
ENFILE	23	File table overflow
ENOBUFS	55	No buffer space available
ENODEV	19	No such device
ENOENT	2	No such file or directory

ENOTDIR	20	Not a directory
ENOTEMPTY	66	Directory not empty
ENOTSOCK	38	Socket operation on non-socket
ENOTTY	25	Not a typewriter
ENXIO	6	No such device or address
EOPNOTSUPP	45	Operation not supported on socket
EPERM	1	Not owner
EPFNOSUPPORT	46	Protocol family not supported
EPIPE	32	Broken pipe
EPROCLIM	67	Too many processes
EPROTONOSUPPORT	43	Protocol not supported
EPROTOTYPE	41	Protocol wrong type for socket
ERANGE	34	Result too large
EROFS	30	Read-only file system
ESHUTDOWN	58	Can't send after socket shutdown
ESOCKTNOSUPPOT	44	Socket type not supported
ESPIPE	29	Illegal seek
ESRCH	3	No such process
ETIMEDOUT	60	Low-level packet transmission could not be accomplished in one or both directions. Either the connection request or its reply failed to get through.
ETOOMANYREFS	59	Too many references: cannot splice
ETXTBSY	26	Text file busy
EUSERS	68	Too many users
EVMSERR	65535	VMS-specific error code for non-translatable errors from VMS to C
