Dynamic Trunking Protocol (DTP) is used to allow switches to share trunk information to reduce configuration however it poses a security risk should a Threat Actor plug into a port with DTP enabled. *Always* keep unused ports in `shutdown` mode and assign them a dead VLAN.

Running `command1 & command2` will run `command1` and >immediately< run `command2`.
Running `c1 && c2` will run `c1` and >only< run `c2` if `c1` exited successfully.

On IPv4 networks, Address Resolution Protocol (ARP) is the mechanism used to locate the physical address of NIC and map it to the IP address. ARP does not cross Layer-2 boundaries so the skid saying he sees your MAC address across the internet is lying.

Network Address Translation (NAT) modifies either (or both) the source and/or destination Layer-3 address of a packet. There are two ways to implement NAT:

Hide NAT which is a "many:one" ratio and
Static NAT which is a "one:one" ratio

You can NAT with IPv6 but... Why? 🙃💚

Infodump on #VPN #Networking #NetSec #SSH #TechTipOfTheDay

Traditionally, VPNs use ISAKMP (IKE) on UDP/500 or TCP/4500 for Phase-1 negotiation and IPSec on IP/50 for Phase-2. This would make it easy for ISPs to block "VPN" traffic. Of course, VPNs have evolved over time...

UK government asks everybody to stop using VPNs.

"everybody who's out there thinking of using VPNs...verifying your age keeps a child safe...So let's just not try and find a way around. Just prove your age."

To check the connections currently running through a #CheckPoint firewall, run: `fw tab -t connections -s` for a full summary. Be careful! Running `fw tab -t connections -x` will drop all the connections. Always verify which command switch you've typed especially in prod.

Getting rid of a disk? Zero it out (at least) three times by "imaging" it with the `/dev/zero` character device.

dd if=/dev/zero of=/dev/sda bs=4M

⚠️ Make SURE you triple-check which device you're using as your output file (of=) to make sure you don't lose your active disk.

Sub-policies in #CheckPoint #firewall let you create one overarching rule to cover an entire section and then narrow down specifics. This saves on processing time as packets not destined for the parent rule are skipped.

Most numeric keypads have a Braille button on the "5". Memorize this so that you can cover your PIN entry with your other hand to prevent cameras from seeing what you're PIN is. Bonus points for having repeating digits in case the camera is thermal. Also, jiggle the keypad.

/tmp and /dev/shm are two temporary storage areas on a *nix system. While /dev/shm may not be there (depending on your OS), /tmp is always there. Contents stored in /tmp are stored in virtual RAM so if you have swap space configured, the contents *may* end up on disk.

Just for fun, here's a really old one...
To load the first binary on device 8 on your #Commodore64, you would run `LOAD "*",8,1"` Once loaded, you issue the `RUN` command to execute it.
Want a directory listing of the device instead?
`LOAD "$",8` followed by `LIST`

You don't have to send the output of a command to pipe through grep if the targets of the command are grep-able.
