When I opened wireshark (fresh install of live usb kali with persistence) for the first time it complained about me being root. This is what I found in googling it:
Yes it's recommended and advisable not to run such tools in super user or high permission account. Giving root to such tools can go sideways should the tool malfunction. You can create a non-super user account or non root account and that should fix the error dialog. Also, the tool should still work when that error dialog shows up, It just warns you of the privileges you are assigning to the tool.
But when I create a user and try to log out as root, I get stuck in an autologin loop as root. I also saw elsewhere that most of the tools in Kali require root permissions (I figured I'd just sudo everything. I started in ubuntu years ago and have become so used to sudo I prefer it to root account).
But my question is: which is the proper way of doing things in Kali? Creating a sub-account and disabling the log in (thus, my sub question is how?) or disabling the warnings in
wireshark. What can go wrong with
wireshark if you run it in root ?
And finally: is this some kind of hazing ritual with Kali? (Bill Labanovic jokes in his book on python that installing pip is a kind of hazing ritual for new programmers in python. I thought maybe this is like that).
UPDATE: Even when I find a way to log in as non-root (by waiting for the screen to lock and selecting a different user) I can't run wireshark because I don't have the permissions! And I can't seem to figure out a way to run wireshark with permissions without resorting to cli!
Update2: I am not new to linux. By a "fresh install of live usb with persistence" I mean I just set up a live usb stick with kali linux and configured persistence following tutorials like this.
The error message in wireshark is this one. Most of the tutorials I found online are about disabling the warning.
I have set up a sudoer account but every time I boot Kali or attempt to log out of Kali, I go through the boot process and the last item is always something along the lines of 'Started up User Manager for UID 0.', as in root. How do I disable this?
Update3: I'm going to clarify my question: what is the normal, correct way of doing this in Kali. According to the meta question on Kali questions, Kali doesn't even have proper apt support. So I'm afraid to go following the directions Draconis posted, because it requires installing special libraries. I'm not trying to run Kali as a production environment or a normal desktop (I have it on a flash drive), I'm just trying to use some tools in it to pentest my server (I am totally new to pentesting, and even though pentesterlab says not to bother using Kali, but just use the distro you're already comfortable in, I didn't want to go installing wireshark and a bunch of other tools in my desktop distro--I figured I'd start learning the basics of pentesting in Kali with pre-rolled tools. Perhaps this was a mistake). I did figure out how to log out as root: it requires using the lock screen button. Sounds amateur not to know that, but I'm not used to gnome and I spend more time in cli than not. I run an ubuntu server and mostly use my bunsenlabs box to mess around with mysql databases and write python scripts with
vim. And it seems funny to me that I can't log out as root without getting stuck in an autologin loop.
I am not new to linux. But I have been using, for the past 10 years off and on, somewhat easier distros (ubuntu, crunchbang, and now bunsenlabs. Have even dipped my toes into slackware and fedora). But for a tool that I figured was meant to be started up on a flash drive, there's an awful lot of configuration that has to happen before I can even get started using wireshark. This doesn't make sense to me. There is no way that a pentester goes and sets up special accounts to run wireshark every time he boots his flash drive (given most people, I would imagine, wouldn't even bother setting up persistence).
So my question is: is it thoroughly normal to run wireshark as root in Kali Linux when running it from a flash drive? If it is not, what is the typical way of doing things in Kali?
