How to encrypt /home directories in Ubuntu 20.04 with an alternative to eCryptfs?

I have a specific use case in which there are multiple users and I only need the Home folder for each encrypted using something like eCryptfs – – but it is buggy and under-maintained and many have reported does not work with Ubuntu 18.04+ and even sometimes stuck in a login loop. Any alternative to eCryptfs? Thanks

MAKE not detecting nested directories for #include

I’m attempting to build OBS-studio-webrtc (live streaming software) from source on a Linux box running Ubuntu 18.04.

There are two main git clones – OBS-studio-webrtc itself, and the webrtc package.

I’m encountering a recurring issue in which most of the .h and .cpp files (possibly all; haven’t checked the 267,544 files in the webrtc directory) do not recognize the directories implied in the #include calls.


audio_processing.h, located at webrtc/include/audio, contains the initial includes:

#include "rtc_base/criticalsection.h"  #include "rtc_base/thread_annotations.h" 

both of which are located in webrtc/include/rtc_base

but running -make returns “No such file or directory”.

Changing the syntax to <rtc_base/thread_annotations.h> produces the same result.

I can write the full directory "home/arctos/Desktop/stream/webrtc/rtc_base" for each include call and that works, but the webrtc package is massive and I’d rather find the root cause as opposed to working through each fatal error one by one.

I’ve used a variety of different OBS-studio-webrtc forks as well as a few different webrtc packages but this same error always presents itself. The webrtc directories and include files are all listed on the Findlibwebrtc.cmake file and appear in the output when

cmake -DUNIX_STRUCTURE=1 -DBUILD_BROWSER=ON -DCEF_ROOT_DIR="../../OBS-studio-webrtc" .. 

is called prior to the -make call. I’ve experimented with installing webrtc both as local user and as root, but no difference. I currently have the builds inside a single folder on the desktop.

I’m assuming the issue is my unfamiliarity with CMAKE, but I’m unable to resolve the issue.

Rsyslog not saving logs from another servers into custom directories [migrated]

I am receving logs on UDP 514 from another server and i have configured rsyslog.conf to save the logs to another custom directory but i am unable to do so, i confirmed through tcpdump logs are getting on 514 but not getting saved. Any thing i’ve missed?

Here’s the config i’ve made in rsyslog.conf

$  umask 0000  # ownership and permissions $  FileOwner punk $  FileGroup punk $  FileCreateMode 0640 $  DirCreateMode 0755   # save that when possible $  PreserveFQDN on   # local ruleset (to control local syslogging) $  RuleSet local $  template CustomFormat,"%TIMESTAMP:::date-rfc3339% %HOSTNAME% %syslogtag%%msg:::sp-if-no-1st-sp%%msg:::drop-last-lf%\n" $  ActionFileDefaultTemplate CustomFormat  $  template prod1,"/ab/cs/edl/172.x.x.x/%$  now%.log"    if $  fromhost-ip == '172.x.x.x' then ?prod1   

How can we protect encrypted files and directories from being fingerprinted when stored on online storage services?

Assuming that online storage providers are considered untrusted, if files and directories are encrypted, how can these be protected against fingerprinting?

The files are encrypted using rclone’s implementation of Poly1305 and XSalsa20 before being backed up to the cloud provider.

According to rclone’s documentation, the available metadata is file length, file modification date and directory structure.

  • What can be identified?
  • What can be inferred?
  • What attack vectors are there against the encrypted files and directories if the online storage provider is compromised assuming the passphrase is at least 24 characters long and is a combination of alphanumeric and special characters (uppercase and lowercase) as well as salted with similar entropy?

The encrypted data is considered to be sensitive.

How can I protect those files from being fingerprinted and the contents inferred such as ownership, source and the like?
