Table 12-9  UUCP Error Messages by Number
Message Number
Base Value for Error Messages
Error messages begin at this value.
Command–Line Usage Error
The command was used incorrectly, for example, with the wrong number of arguments, a bad flag, or a bad syntax.
Data Format Error
The input data was incorrect in some way. This data format should only be used for user's data and not system files.
Cannot Open Input
An input file, not a system file, did not exist, or was not readable. This problem could also include errors like “No message” to a mailer.
Address Unknown
The user that was specified did not exist. This error might be used for mail addresses or remote logins.
Host Name Unknown
The host did not exist. This error is used in mail addresses or network requests.
Service Unavailable
A service is unavailable. This error can occur if a support program or file does not exist. This message also can simply indicate that something does not work and the cause currently is not identifiable.
Internal Software Error
An internal software error has been detected. This error should be limited to non-operating system-related errors, if possible.
System Error
An operating system error has been detected. This error is intended to be used for conditions like “cannot fork”, “cannot create pipe.” For instance, this error includes a getuid return of a user who does not exist in the passwd file.
Critical OS File Missing
A system file such as /etc/passwd or /var/admin/utmpx does not exist, cannot be opened, or has an error, such as a syntax error.
Can't Create Output File
A user-specified output file cannot be created.
Input/Output Error
An error occurred while doing I/O on some file.
Temporary Failure. User is invited to retry
Temporary failure that is not really an error. In sendmail, this means that a mailer, for example, could not create a connection, and the request should be reattempted later.
Remote Error in Protocol
The remote system returned something that was “not possible” during a protocol exchange.
Permission Denied
You do not have sufficient permission to perform the operation. This message is not intended for file system problems, which should use –NOINPUT or –CANTCREAT, but rather for higher-level permissions. For example, kre uses this message to restrict students who can send mail to.
Configuration Error
The system detected an error in the configuration.
Entry Not Found
Entry not found.
Maximum Listed Value
Highest value for error messages.
