Description
Define tracing operations for TCP port forwarding processes.
Options
file filename—Name of the file to receive the output of the tracing operation.
Enclose the filename within quotation marks. All files are placed
in the directory /var/log.
files number—(Optional)
Maximum number of trace files to create before overwriting the oldest
one. If you specify a maximum number of files, you also must specify
a maximum file size with the size option.
Range: 2 through 1000
Default: 3 files
flag flag—Tracing
operation to perform. To specify more than one tracing operation,
include multiple flag statements. You can include the following
flags:
all—Trace all eventsconfiguration—Trace configuration eventsconnection—Trace TCP connection eventsinit—Trace TCP port forwarding initialization events
level—Level of tracing to perform; also
known as severity level. The option you configure enables tracing
of events at that level and all higher (more restrictive) levels.
You can specify any of the following levels:
all—Match all levels.error—Match error messages.info—Match informational messages.notice—Match notice messages about conditions requiring special handling.verbose—Match verbose messages. This is the lowest (least restrictive) severity level; when you configureverbose, messages at all higher levels are traced. Therefore, the result is the same as when you configureall.warning—Match warning messages.
Default:
error
match regular-expression—(Optional)
Refine the output to include lines that contain the regular expression.
no-remote-trace—(Optional) Disable remote tracing.
no-world-readable—(Optional) Disable unrestricted
file access.
size maximum-file-size—(Optional)
Maximum size of each trace file. By default, the number entered is
treated as bytes. Alternatively, you can include a suffix to the number
to indicate kilobytes (KB), megabytes (MB), or gigabytes (GB). If
you specify a maximum file size, you also must specify a maximum number
of trace files with the files option.
Syntax:
sizekto specify KB,sizemto specify MB, orsizegto specify GB
Range: 10240 through 1073741824
Default: 128 KB
world-readable—(Optional) Enable unrestricted
file access.
Required Privilege Level
trace—To view this statement in the configuration.
trace-control—To add this statement to the configuration.
