[Solved] Erasing/editing SanDisk Cruser Fit 64GB that is "READ ONLY" (it wasn't!)

[RHEL 8] I remember seeing a fairly recent post either here or FedoraForum regarding marking/unmarking a USB key as read-only but I'll be 'dang-ed' if I can find it. That said: I started transferring my music collection to this (whatever default FAT version) USB key using the Gnome copy/paste - unti...

Re: Logging all executed instructions

I think it's already being logged. Does this help?

Code: Select all

sudo grep "CMD" /var/log/secure
and for script commands executed by cron:

Code: Select all

sudo grep "CMD" /var/log/cron

Re: email server - VERY small scale

As far as my 'email server' experiment: I'm undecided where to go from here - non-working (certificate complaints) but all services running fine. The machine mail command results (I think) are winding up in that users' system var/mail. Clearly, I need more knowledge before attempting this; I've mess...

Re: email server - VERY small scale

:lol: I'd sensed displeasure some time ago! Thanks - knowing that I will feel better about exploring, playing with, & learning nftables without fear of creating conflicts with the few things I'd done in firewalld. I'd never really tried anything with iptables as I didn't feel I knew enough about the...

Re: email server - VERY small scale

Thank you - I got all the expected results you mentioned. An Aside: May I gather from this that firewalld is essentially a 'front-end' to nftables? I've been trying to figure this out for a long time; I always thought it was a '3rd' option to nftables and the old.iptables and never understood the co...

Re: email server - VERY small scale

So, in there I found smtp-submission.xml. Then:
# systemctl enable --now smtp-submission
Failed to enable unit: Unit file smtp-submission.service does not exist.
I am learning, but don't know enough to understand what I need to do now. :?

email server - VERY small scale

RHEL 8 Experimenting with trying to set up an email server for perhaps 6-8 users and following RHEL 8 Documentation. I've NOT yet forwarded ports from 'the outside' - and that may be a while, or never at all! That said, I run across these instructions: Configure the firewall for sending and receivin...

Re: CentOS 9 : desktop functionality question

I have a RHEL 9 VM (not CentOS) and, for now, dislike that it starts by default in "Activities" mode with the oval of commonly used activities at the bottom center. Because of your query, I paid attention to that oval, 2nd from the right was Terminal". Simply <click> on it. This might be a good thin...

Re: tracker-extract 100% CPU

Additional tracker info: I run RHEL 8 with Gnome and used 'rpm -e --nodeps tracker' and 'rpm -e --nodeps tracker-miners' on one of my systems. The operation worked and my system still ran/booted well. Today I learned that Gnome uses them heavily to operate it's GUI menu file services (spinning 'busy...
