Hi,

How to check telnet services is enable or not.

Please share cli command or Web GUI steps so I can check.

Telnet is not enabled by default, nor is it recommended.
The clish command to check is show net-access.
You can check in WebUI under Network Access.

Hi,

Thanks for update, but the command your shared "net-access" is not work in clish & expert mode.

I have checked in WebUI I it's showing it's disabled. I have total 5 checkpoint firewall gateways & in two gateway (Open Server R77.30) WebUI I got the details, but other 3 gateway I am not able to check because "Network Access" option is not showing.

In this 3 gateway are appliance 2200 & R77.30 GAIA OS is installed, but when I logged in this gateway WebUI the login page is showing as R80.X. I have management open server R80.10.

The command show net-access should work in R77.30 and later for sure, assuming it's Gaia OS.
Here's a screenshot of what it should show in the WebUI (from R77.30).

Please post a screenshot of the relevant systems.

Telnet is disabled by default. There is no telnetd rpm packet installed on GAIA.

Check the telnet port😀.

# netstat -an | grep 23

Kindly enter the below command in clish mode,

> show configuration net-access

Then verify output which must be in below format to ensure about telnet is off, "set net-access telnet off"

This is basic hardening point of firewall.
