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 events
configuration—Trace configuration events
connection—Trace TCP connection events
init—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 configure verbose, messages at all higher levels are traced. Therefore, the result is the same as when you configure all.
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: sizek to specify KB, sizem to specify MB, or sizeg to 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.
