rkhunter returned warnings after upgrading to openSUSE Leap 15.4

Linux Questions - Thu, 10/06/2022 - 06:11
Hi,

I need help understanding the results I got with rkhunter after upgrading to 15.4.

So my practice is that every time I do an update, I always run

Code: sudo rkhunter --propupd --pkgmgr RPM afterwards so that whatever was updated by me gets updated in rkhunter's records (and thereby not inadvertently flag such updates as a warning later on). I did that after running the upgrade and just before rebooting to allow the distro upgrade changes to take effect. After rebooting, however, I got a couple of warnings (see below):

Code: Checking for group file changes [ Warning ]
Warning: Group 'sgx' has been added to the group file.
Warning: Group 'games' has been added to the group file.

Checking for passwd file changes [ Warning ]
Warning: User 'games' has been added to the passwd file.
Warning: User 'brltty' has been added to the passwd file.

Checking for hidden files and directories [ Warning ]
Warning: Hidden file found: /usr/bin/.hmac256.hmac: ASCII text The warning for the group and passwd files were gone after the next reboots, but the warning for the hidden file seems to persist. My questions are:
  1. Are these changes normal after doing a distro upgrade? (This is my first time to do a distro upgrade with rkhunter in active use)
  1. What were those group file and passwd file changes for?
  1. Is that hidden file a threat? If it is, what remediation steps should I do? If not, what can I do to tell rkhunter that it should not be detected going forward?

For number 3, I believe it that file previously existed in Leap 15.3 then was changed to a hidden file upon upgrading to 15.4. I'm not sure what that file is and why it was made hidden after upgrading to 15.4. If in case it is because it was replaced by something else, then why wasn't it removed?

Please advise. Thanks in advance.

Slackware installed EFI to wrong ESP in dual boot scenario

Linux Questions - Thu, 10/06/2022 - 05:59
hey guys, i'll try and keep this short, but it's somewhat complicated:
i started properly dailydriving linux with slackware current in dualboot with windows on a 1tb nvme ssd.
since the linux install was an afterthought, the partitioning was done pretty dirty, so eventually i decided to redo my whole system on a dedicated new nvme.
i installed windows, and afaik it installed its boot files into the correct esp (it has about 30MiB used). with the help of a friend i managed to install slackware 15.0 in an encrypted LVM. i use grub2 for dual booting, and in itself it's working flawlessly.
when installing slackware, i probably overlooked the dialog about detecting the EFI partition - it must have selected the ESP of my old disk and installed the EFI there. i noticed when checking gparted and doing a sanity check on my files - /boot/ is mounted correctly, but /boot/efi is mounted from the wrong ssd.
i would like to wipe that old ssd and use it for different things, but now i first have to move slackware's files from the old esp to the new one, re-configure grub and keep the preexisting windows files in the new ESP intact.
since i'm still fairly new to linux (and especially to problems like this) i would really appreciate some guidance.
my current partitioning is like this:

old disk (i want to wipe this)
Code: /dev/nvme1n1p1 249.9G NTFS # my old windows
/dev/nvme1n1p2 500M  vfat # esp
/dev/nvme1n1p3 431.5G NTFS # some space for storage
/dev/nvme1n1p4 249.6G EXT4 # my old slackware (current) new disk (i want to keep this)
Code: /dev/nvme0n1p1 100M  vfat # new esp
/dev/nvme0n1p2 16M        # magic windows partition
/dev/nvme0n1p3 224.6G NTFS # my new windows
/dev/nvme0n1p4 2G    EXT4 # unencrypted /boot/ partition
/dev/nvme0n1p5 239.1G EXT4 # encrypted LVM for my new slackware (15.0)

mtpaint scripting

Linux Questions - Thu, 10/06/2022 - 05:55
Hi,

I have trouble following the mtpaint handbook in getting my own mtpaint scripting going.
My version calls itself mtPaint 3.50 while the package it came from calls itself mtpaint-3.49.32-x86_64.

I read https://mtpaint.sourceforge.net/hand...B/chap_10.html and have issues here:
Quote: First is direct execution. Select 'Image->Scripts->Configure' menu option, choose a free script slot in the list on top, enter the commands in the window below, press "Execute", and it will happen. If there is an error in your script, execution will stop on it and the problem will be reported. There is no such thing as Image->Scripts->Configure'
When I click Image->Scripts I get this
https://abload.de/img/mtpaint_scriptgqfdh.png

Do I do something wrong, or do I need to find a more in depths HOWTO about mtpaint's scripting ability?

I want to create a simple script:
resize to 1920x1080
Unsharp Mask - Radius 5 Amount .5 Threshold 0 [x] Gamma corrected
save with same file name

or minimal variants, like
resize to 1920x1080
Unsharp Mask - Radius 5 Amount .7 Threshold 0 [x] Gamma corrected
save with same file name

or
resize to 1920x1080
Unsharp Mask - Radius 5 Amount .4 Threshold 0 [x] Gamma corrected
save with same file name

Any tips appreciated on how to get to the 'Image->Scripts->Configure' part.

Two disks have been cloned and look same, since UUID is identical. The OpenSuse Leap 15.3 won't mount it.

How to force it?

LXer: Use OCI containers to run WebAssembly workloads

Linux Questions - Thu, 10/06/2022 - 03:20
Published at LXer:

WebAssembly (also referred to as Wasm) has gained popularity as a portable binary instruction format with an embeddable and isolated execution environment for client and server applications. Think of WebAssembly as a small, fast, efficient, and very secure stack-based virtual machine designed to execute portable bytecode that doesn't care what CPU or operating system it runs on.

Amavis RelayedOpenRelay

Linux Questions - Thu, 10/06/2022 - 01:24
Hello,

I have a mail server running Amavis and Postfix, which were configured from a web-based tutorial.

I really have no idea about the inner workings of these email protection solutions, and I really hope I've configured them correctly.

However, in my Logwatch, I see lines like this:

Code: 1  (702006-13) Passed UNCHECKED-ENCRYPTED {RelayedOpenRelay}, [127.0.0.1] [xx.xx.xx.xx] What does "RelayedOpenRelay" mean ?
It means that my Postfix is open ? I really hope not!

I've done some testing at mxtoolbox.com and it doesn't seem to be open.
However, I think mxtoolbox.com tests on Port 25.
What about other open ports used by Amavis ?

I really don't know the flow of events of how these solutions work.

I googled for a few hours before I found that something must be done in @mynetworks and local_maps, I don't know... However, I don't have amavis.conf file in my system...

Anyone has any experience with Amavis ? Can anyone help me set up amavis accordingly ? And what does "RelayedOpenRelay" mean ?

Thank you !!
