fw ctl get

Description

Shows the current value of the specified kernel parameter.

Notes:

Kernel parameters let you change the advanced behavior of your Security Gateway.
There are two types of kernel parameters - integer and string.
Security Gateway gets the names and the default values of the kernel parameters from these kernel module files:
- $FWDIR/modules/fw_kern_64.o
- $FWDIR/modules/fw_kern_64_v6.o
- $PPKDIR/modules/sim_kern_64.o
- $PPKDIR/modules/sim_kern_64_v6.o

Important:

In a cluster, the value of the specified kernel parameter must be the same on all members of the cluster.
In VSX Gateway, the configured values of kernel parameters apply to all existing Virtual Systems and Virtual Routers.

In addition, see the fw ctl set command.

Syntax

fw [-d] ctl get

int <Name of Integer Kernel Parameter> [-a]

str <Name of String Kernel Parameter> [-a]

Parameters

Parameter	Description
`-d`	Runs the command in debug mode. Use only if you troubleshoot the command itself.
`<`Name of Integer Kernel Parameter`>`	Specifies the name of the integer kernel parameter.
`<`Name of String Kernel Parameter`>`	Specifies the name of the string kernel parameter.
`-a`	Specifies to search for this kernel parameter in this order: In `$FWDIR/modules/fw_.o` In `$PPKDIR/modules/sim_.o`

Example for an integer kernel parameter

[Expert@MyGW:0]# fw ctl get int fw_kdprintf_limit -a

FW:

fw_kdprintf_limit = 100

SIM:

fw_kdprintf_limit = 100

[Expert@MyGW:0]#

Example for a string kernel parameter

[Expert@MyGW:0]# fw ctl get str fileapp_default_encoding_charset -a

FW:

fileapp_default_encoding_charset = 'UTF-8'

SIM:

Failed to get from ppak
