The WSTLSD daemon is responsible for handling HTTPS Inspection related issues on the Security Gateway. It performs SSL/TLS termination and re-encryption, certificate validation and generation, and URL categorization for HTTPS traffic1. The WSTLSD daemon can be debugged using the command wstlsd debug on TDERROR_ALL_ALL=52. The debug file is located in $FWDIR/log/wstlsd.elg2. The other daemons, such as FWD, HTTPD, and VPND, are not directly related to HTTPS Inspection, but rather to policy installation, web server, and VPN, respectively. References: 1: sk65144: HTTPS Inspection Architecture 2: sk83520: How to debug the WSTLSD daemon

 The CPD process controls logging on the Security Management Server or the Log Server. It is responsible for receiving logs from the Security Gateways, storing them in the log files, and forwarding them to the SmartLog and SmartEvent servers. It also handles the communication with the SmartConsole clients and the CPM process. The CPD process runs on the Security Management Server or the Log Server as part of the Management High Availability module.

To see the list of processes monitored by the WatchDog process (CPWD), you use thecpwd_admin listcommand.

Option A (cpstat fw -f watchdog): Shows firewall status and statistics for the "fw" context, not necessarily the list of monitored processes.

Option B (fw ctl get str watchdog): Not a valid parameter for retrieving the list of monitored processes; “fw ctl” deals with kernel parameters.

Option C (cpwd_admin list): Correct command that lists all processes monitored by CPWD, their status, and how many times they have been restarted.

Option D (ps -ef | grep watchd): This will list any running process that matches the string “watchd” but will not specifically detail which processes are being monitored by CPWD.

Therefore, the best answer iscpwd_admin list.

The simplest and most efficient way to check all dropped packets in real time is C. fw ctl zdebug + drop in expert mode. This command is a shortcut command that sets the kernel debug flags to a predefined value and prints the debug output to the standard output. It is useful for general debugging of common issues, such as traffic drops, NAT, VPN, or clustering. It has a small buffer size and does not require additional steps to start or stop the debugging. However, it has some limitations, such as it cannot be used with SecureXL, it cannot filter the output by chain modules, and it cannot save the output to a file12.

The other commands are not as simple or efficient as the fw ctl zdebug + drop command. The command tail -f $FWDIR/log/fw.log |grep drop in expert mode will only show the drops that are logged in the fw.log file, which may not include all the drops that occur in the kernel. The command cat /dev/fw1/log in expert mode will show the raw binary data of the kernel debug buffer, which is not human-readable and may contain irrelevant information. The command Smartlog will show the drops that are indexed and stored in the SmartEvent database, which may not be in real time and may depend on the log server performance12.

The Check Point R81.20 Gaia Administration Guide describes fw ctl zdebug as a key troubleshooting tool for real-time packet analysis, particularly for drops. The CCTE R81.20 course emphasizes using fw ctl zdebug for kernel-level debugging, including monitoring dropped packets.
