ser2net - unable to connect to the server

wicKeD deVianT
Hiya there. Subject line kinda' nails it; I'm thoroughly Wicked, and noticeably Deviant. I am also -allegedly- about 46 years into this life, living in Sweden, and most likely male. I mainly use Ubuntu Studio, Mint Cinnamon, Open Suse with KDE, and Manjaro, also with KDE. Additionally I admit to taking way too much pleasure in recreational Distro-hoppin', but the aforementioned quartet tends to always come out on top, no matter how many new ones I try out.
I also claim the title of multi-instrument-wielding musician.
That's about how the cookie crumbles. Unless you eat it prior to said crumbling.

How to retrive mail from nobody
Hi everyone,
I reconfigured (badly) postfix because FQDN changed (fixed now) and all root emails temporarily were sent to nobody account '/var/mail/nobody'
Now I have a chunk of emails and I do not know if it is a way to retrieve then to root. The /etc/aliases has the relevant entries:
Code: nobody: root
postfix: root
postmaster: root and newaliases updated the db.
I am thinking of a command to let MDA to move from to root all the emails. This is not about postqueue!
I switched MTA to sendmail/exim4 but no success obviously
Thanks a lot!

XDG_SESSION switching from X11 to wayland automatically when I switch User in RHEL 8
I'm executing a shell script inside profile.d, which needs x11 as the default gnome-session. It works fine when I login into system as USER1, but the XDG_SESSION_TYPE is shifting from x11 to wayland when I try to switch user to USER2 as a result not executing my script in profile.d. I've removed the comment for the line Wayland=false from the custom.conf located in /etc/gdm/ to make x11 as default XDG_SESSION_TYPE. Can anyone help me with making x11 as default for the second logged in user as well!?
I've found that multiple TTY sessions can support Xorg simultaneously, but I'm unable to do that in my RHEL 8 system. Second User session is being started in wayland.

Python Script to Download LinuxMint
Hi all,
I cobbled up a little Python script to download the latest LinuxMint releasesboth the main LinuxMint isos and the LMDE ones. You can find the script attached to this post.
It will look at the LinuxMint home page and extract the latest LinuxMint version, as well as the latest LMDE version, from the Download dropdown on the page. It will ask you if you want to download them (to the current directory), assuming by default that you will want to do so if you do not yet have the latest version.
To use it, you will first have to edit it and specify your preferred LinuxMint mirror site on the following line:
Code: LINUXMINT_MIRROR_SITE = '<<<SPECIFY YOUR PREFERRED LINUXMINT MIRROR SITE HERE>>>' To find the list of available mirrors, navigate to the download page of any LinuxMint or LMDE edition and scroll down to obtain the list of locations and the corresponding mirrors.
Feel free to use it or to not use it, as you see fit.

Create a script that mounts a share, checks a file if it has not been modified in 2 or 1 days, and then unmounts it?
Hello
In a monitoring system I have, I had a plugin that remotely checked a SMB share and if the file hasnt been modified in 1 day, it should return a warning. if it is 2 days or more, it should return a critical.
Returning the warning and the critical isnt the issue, its the entire logic of the script itself.
I mean, I dont think it should be too difficult but Im not used to shell scripting. Also, the downfall exists, of having to check if the mount is correct, etc.
Could someone tell me the basics of the shell script?
Thank you.
