Check Point Quick Reference – Tcpdump
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. NOTE: fw monitor operates above layer 2 and does not include mac address information - cant see ARP messages. tcpdump can see layer 2 ARP messages This is one of the most common tcpdump commands: (looks for packets from a src to dst, need to specify interface) tcpdump nn-i eth2 host 11.11.11.11 and host 22.22.22.22 08:02:15.043273 11.11.11.11.62044 > … [Read more...]
Check Point Quick Reference – FW Monitor
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. Overview: FW Monitor is a built-in firewall tool which needs no separate install on the device you wish to capture packets and interrogate connections. It is a functionality provided with the installation of the FW-1 package and syntax is also identical across all FW-1 installations. FW Monitor allows for sampling the connection from 4 different points in the firewall, … [Read more...]
Firewall Commands For Identifying Specific Routes
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. The Question: Using firewall commands, identify the route to specific destination/target without using the routing table (more specific) I was asked the question today, and blanked out... I have ran the Cisco and CheckPoint IPSO versions, but not Splat and still couldn't pull it from memory. Once I looked it up I felt silly, but knew it will be a good addition to my … [Read more...]
CheckPoint SmartDashboard – Missing Menu
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. Hello All. I was bouncing around in the Checkpoint SmartDashboard, updating rules in some firewalls and noticed that the menu bar at the top of the window was missing... After some searching, I found that a registry setting needed to be modified to restore the SmartDashboard menu bar. Here is the registry path that needed to be … [Read more...]
Check Point Firewall – Nokia IPSO CST Hanging or Taking Forever?
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. Is your Nokia IPSO CST Not finishing? Trying to run a CST on your Nokia, but seems to be taking forever? I have had the same issue on various Nokia security appliances running on IPSO 4.2 and older. The problem ended up being hung process that was spawned by the CST program. It seems that CST calls "fw tab -u -t", and sometimes it just gets hung up, but will look to … [Read more...]
Check Point Firewall – Detect SSH over Non Standard Ports
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. Many enterprises deploy proxies these days, but many are not aware that if they are not configured correctly they may be allowing SSH over Non Standard Ports, giving a tech savvy employee the keys to exploit this fault. Most times this is SSH over HTTP/HTTPS, but can also be over other ports, which is less common. Blue Coat proxies detect and drop this type of activity by … [Read more...]
Check Point Firewall – Interfaces Reordered Upon Upgrade
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. A few days ago, one of our Check Point IAS M6 Firefly equiped, R70.20 Splat clusters, had a member fail due to "PLANAR VOLTAGE FAILURE", so says the IBM iLO event log. Since this is not solved by a simple power supply replacement, so an RMA replacement unit from Check Point was obtained. The new device came pre-loaded with R65 and no HFA's or hotfixes. So we distributed … [Read more...]
Check Point Firewall – Backup vs Snapshot
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. Backup procedures Check Point provides three different procedures for backing up (and restoring) the operating system and networking parameters on your appliances. • Snapshot (Revert) • Backup (Restore) • upgrade_export Each of these procedures backs up certain parameters and has relative advantages (such as: file size, speed, and portability), which are fully … [Read more...]
Check Point Firewall – SPLAT CLI Commands
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. Here is a list of SPLAT CLI Commands commands for Checkpoint Secure Platform, that I have compiled from my studies, checkpoint documents, and places around the web. This is by no means an exhaustive or comprehensive list, but is rather meant to be a command line KB of sorts - mainly for my quick reference. The list is split into CP and FW commands. If the list proves … [Read more...]
