comment Is it possible to save data as per the incoming protocols in ascii?
Let us continue this discussion in chat.

comment Is it possible to save data as per the incoming protocols in ascii?
E.g., I tend to use wireshark/tshark, not tcpdump (no reason, just habit) for looking at stuff, and for capturing packet data for processing I would just write code (it's probably simpler than parsing a capture from an application), so I'm aware of but not so familiar with tcpdump. But seeing this led me to the man page -- hopefully the answer helps.

Okay. Part of the reason for wanting people to be clear and demonstrate they understand what they are trying to do is that most people (including me) don't have an infinite amount of time and will tend to shy away from questions where it looks like either a lot of back and forth prying has to go on, or where it is likely to end up in, "Oh no that's not what I want" or "Oh I already tried that"...

To ask this question properly, I think you need to explain the nature of the data you are receiving explicitly, and in reasonable detail and what form you want it to end up in ("ascii" is very ambiguous). If you are waiting for someone to come along who works regularly with automotive gateways, you are going to be waiting a long time. If instead you target someone who understands IP communication inside out, that is a much, much easier order to fill.

For example regarding the XY problem: If this is about interpreting pcap data, look into interpreting pcap data (as purplepsycho says). It doesn't matter where it came from. If this is about extracting data from network packets generally, that's not the same as "saving a stream in ascii", even if that is the end goal.

"this packs all the data in to a single Ethernet frame" -> Note an ethernet frame is max ~1500 bytes. I sense an XY problem here in that your (no offence) hazy understanding of networking fundamentals is getting in the way. I suggest you look at what it is you need to do for aspects you are uncertain of, or may have made drawn wrong conclusions about, then research and ask questions about those. Right now, your description is so vague it is really impossible to say much.

comment How to change color of a character while tailing and tr
@DavidEverlöf Good question...I'm guessing I meant to explain that as whatever character (as in "replace a with b") ??? But the OP got it so I never noticed. Anyway, I've replaced that with \001 to match the question.

comment How can I find available network interfaces?
[Later] Sometime in the past year Fedora or systemd corrected that? My PCI ethernet is now eno1.

It is a bit obtuse. Have a look in /var/log/boot.log -- I don't have a SysV system to check except for logs from <= Debian 7, and I don't save copies of that one. WRT "Did it run?", look at dumpe2fs; it will say how many mounts since the last check.
