Key material (random bits and other mathematical data) as well as an agreement on methods for IKE phase II are exchanged between the peers. The point of my answer was that whether or not RSA is used for key exchange or for used for data directly depends on the use case. Wireshark supports TLS decryption when appropriate secrets are provided. Most of the example utilizes openssl. By applying the formula fm=b^c, the value will be calculated.

If you have a copy of the private key (such as the RSA private key used for signing and authentication in cipher-suites utilising RSA), and the cipher-suite in use does not provide perfect forward secrecy (through the use of diffie-hellman key agreement, instead of traditional RSA key exchange for example), then yes.

Having issues with PXE — not sure where to go next
I recently got some new Raspberry Pi 4’s I’ll be using for various serving tasks on my network. I’ve got a 2U rack printing for them as we speak!
Problem, though: I forgot to get SD cards. Fine. I had been meaning to try out PXE on a Pi before, and this is a good opportunity.
So, a little bit of context on the topology. We have an ISP-provided, disgusting, absolutely horrible 2-in-1 DSL modem/router. I do IP passthrough to a router immediately behind it.
Ethernet goes off every which way, including to two unmanaged switches. The PXE client is on one of these switches. My DNS/DHCP is on the other (Pihole).
On the same switch as the DHCP server is a fileserver I built. It’s what I’m attempting to use as the PXE server.
I mention the topology because I’m not sure if maybe it matters for some reason.
If I watch packets on Wireshark, I see the typical DOR of DHCP DORA, but no ACK packet. If I inspect the dnsmasq logs on the pihole, I see the full DORA exchange. On Wireshark, the OFFER packet comes from my fileserver — I don’t see an offer from the pihole. However, I can see all other DHCP DORA conversations from the pihole with other devices requesting leases.
The PXE client, after not receiving an ACK, sends out another DISCOVER, triggering another DOR loop. This goes on forever.
So, some questions:
Why would the PXE client not be receiving the ACK packet? Why can’t I see it on the network, even though the DHCP server claims to be sending it?
Why can I see an OFFER packet from my fileserver, but I cannot see the OFFER from the DHCP server?
Why is this the case only for the PXE client? I can see the full DORA for other clients.
Really at a loss here. Not sure what to try next. The dnsmasq man pages weren’t particularly helpful, nor are the large number of blog posts that appear to be verbatim copies of the Raspberry Pi Foundation’s PXE tutorial.
Priortizing InfoSec skills
To that end, I wanted to get everyone's opinion on how they prioritize which skills to spend more time working on. To better clarify, I'm certainly not saying anything should be overlooked, just what I should focus my time on to the greater extent.
The way I've been thinking about it, is kind of like a primary and secondary skill and then a base level skill. And for the purposes of this post, the term "skill" is referring to the high level area of information systems
As far as credentials go, as of now, I have;
- BS in CS
- CCNP Enterprise
- I am knowledgeable about configuring and troubleshooting core switching, WAN routing, VPNs (or at least using GRE/IP sec).
- I am excellent at using wireshark for a wide array of purposes (malicious traffic monitoring, troubleshooting several network issues, etc.}
- I am pretty good with nmap
- To a lesser extent I'm pretty comfortable with (that is to say that I have routine hands-on experience with them but no formal training) NGFWs (SonicWall) and SEGs (Barracuda).
With that said, I would say, outside of the C++/Java that was my entire CS curriculum, I haven't done much programming. I'm familiar with PowerShell and TCL but outside of that, I haven't had much hands-on experience with any other language. I will mention that I do tend to pick them up fairly quickly as the I could easily follow a flowchart of a program/script, I would just need to pick up the syntax.
After that, one of my weaker areas is Linux in general. By that, I mean the OS as a whole, not specific tools. Almost all of my Linux knowledge is based on using Linux tools (Aircrack, Nmap, etc) and Cisco IOS. I am pretty well versed in RegEx but outside of that, I don't know much.
The last point I'll make is SQL. Outside of knowing what it is, I have no experience in it.
So with all of that said, how should I split my time in terms of keeping/developing my stronger skills and picking up some of weaker skills. I know there is no one-sized fits all approach to this as it entirely depends on your job, so take it in the context of "general things infosec professionals should know."
Should I look into some cert training for things like ASA/FirepowePA/CP? Should I spend a great deal of time on learning things like Perl/Bash/Python? How important is linux knowledge at the system level, should I get a Linux+/LPIC or is the bits and pieces I pick up from utilizing various tools enough? Should I dive more into VMware?
I know there is no right or wrong answer here, I am just looking for your opinions based on your experiences and anecdotes.
