I have no idea why there are strikeouts in part of the debug, I just copied the entire contents of -vvv
That's ok, one of the Ubuntu version banners contains the ~
character
which GitHub then interprets as the markdown for "start strikethrough".
There isn't another one for a while to end it, which is why so much is
struck out. Happens often and nothing to worry about, we're happy reading
around it. 5;)

As to the issue, I don't know how the symbols were constructed, as
symbol_maker
isn't an official tool. That means it may produce an
incomplete ISF which could cause problems (as I say, I don't know how it
does it, it might be fine but I've no way of telling). Lastly, I don't
think --dump
take a parameter, it just outputs all files in the output to
the dump directory (which can be set as a volatility wide value with
vol.py -O directory <normal vol options> <plugin> <plugin options>
. So
if you're looking explicitly for a file called passwd.txt, it probably
won't be there.

Hey @PNW-Hacker,
On the one hand, the CachedPages field, as follows, shows 0 pages, meaning that no pages are currently stored in the Page Cache for the /etc/passwd inode.
$ python3 ./vol.py \
-r pretty -f ~/Downloads/linux.mem \
linux.pagecache.Files --find /etc/passwd
Volatility 3 Framework 2.11.0
| SuperblockAddr | MountPoint | Device | InodeNum | InodeAddr | FileType | InodePages | CachedPages | FileMode | AccessTime | ModificationTime | ChangeTime | FilePath

Also, as you can see below, the plugin doesn't produce any backtrace like the one shown in your output, confirming my suspicion that the tool you're using isn't generating the ISF correctly.
$ python3 ./vol.py \
-f ~/Downloads/linux.mem \
linux.pagecache.InodePages --find /etc/passwd
Volatility 3 Framework 2.11.0
PageVAddr PagePAddr MappingAddr Index DumpSafe Flags
On the other hand, for the /home/paco/pkexecc
file inode, 5 out of 5 pages are in the Page Cache.
$ python3 ./vol.py \
-r pretty \
-f ~/Downloads/linux.mem \
linux.pagecache.Files --find /home/paco/pkexecc

This allows you to recover the entire file content.
$ python3 ./vol.py \

Please read Steps for constructing a new kernel ISF JSON file
in https://volatility3.readthedocs.io/en/latest/symbol-tables.html
In your case, you could have used, for example:

@ikelos please close this issue, not a bug.
@PNW-Hacker , as mentioned symbol_maker
is a tool we don't have much (any) experience with and it appears not to produce suitable symbol tables. There doesn't appear to be a bug in the plugins, hopefully the discussion has given you some direction to follow. If you feel there is still an underlying bug, feel free to reopen this and explain what specific change you think is necessary...
Describe the bug I'm not entirely sure it is a bug (probably), but also the memory dump isn't mine, so idk how much y'all are able to help in this case. But nevertheless, I'll create this and let y'all decide how to proceed (rather that be assist in troubleshooting or classify it as out-of-scope)
There is a TryHackMe room (it's a free room) called Profiles. https://tryhackme.com/r/room/profilesroom While the room does say it's best to be completed using Vol2, I was hoping it could be completed with Vol3.
Context Volatility Version: Volatility 3 Framework 2.11.0 Operating System: Kali Linux (most up-to-date version, running within VirtualBox) Python Version: 3.12.6 Suspected Operating System: Ubuntu 20.05 version 5.4.0-166-generic Command: python3 /home/kali/Desktop/volatility3/vol.py -f linux.mem linux.pagecache.InodePages --find /etc/passwd --dump passwd.txt
To Reproduce Steps to reproduce the behavior:
Within folder: /Volatility_Symbols/volatility_symbols run: python3 symbol_maker.py -d ubuntu -k '5.4.0-166-generic' Since I was running these commands from the github clone I copied the xz file to: /home/kali/Desktop/volatility3/volatility3/symbols/ and then ran unxz to extract it
Use command 'python3 /home/kali/Desktop/volatility3/vol.py -f linux.mem linux.pagecache.InodePages --find /etc/passwd --dump passwd.txt' (I just git cloned the vol3 repo to that directory within Kali, so how you run vol3 probably doesn't matter)
See error I don't get an error with the passwd file, nothing is there
The file I am trying to pull down: /home/paco/pkexecc This file does give me an error: https://github.com/volatilityfoundation/volatility3/issues/1312
Expected behavior I was hoping that the data file would be dumped along with its contents (how you can do in vol2 using enumerate_files -O) If you search for Question 3 within this repo, you'll see that this user uses vol2 and extracts the file, and is able to then grab the md5sum of said file: https://medium.com/@lukwagoasuman236/tryhackme-profiles-write-up-60202db52210
Example output Please copy and paste the text demonstrating the issue, ideally with verbose output turned on (
vol.py -vvv ...
).python3 /home/kali/Desktop/volatility3/vol.py -vvv -f linux.mem linux.pagecache.InodePages --find /etc/passwd [ 3:26AM ]

Additional information This is where it comes into play as to if y'all would be able to help me or if this is out-of-scope. This is for a TryHackMe, so I don't know anything when in regards to how the memory dump was compiled and such, I just know that when running the linux.bash.Bash command, I could see the version of Ubuntu it was running, so I could then build the symbols file
