Re: F38 adding user to dialout group without reboot

I have added me to group dialout:

But I cannot access /dev/ttyUSB0

Does not work but:

sudo screen /dev/ttyUSB0 115200

does.

Dr. Google seems to think I need a reboot for this to work.  I have 
too many things running to want to reboot.


Actually I am trying to get the Arduino IDE stuff to work and it wants 
to use the ttyUSB0 and gets permissions denied.


Is rebooting the only option?




Logout and login again must work

No idea, but you could try

sudo su -

Then:

If Zoom is not a requirement (only video appointment) you can use Jitsi
Meet from browser.

https://jitsi.org/

You can create Meetings in: https://meet.jit.si/ Use a random Meet name
to avoid anyone "guess" and joins it, something like

Re: Printing From Fedora to HP Laser Jet 1020 on D-Link Print Server

I'm going to ask the obvious question:  Is your Linux computer in the
same subnet as the printer?  (i.e. 172.16..)


Yes

Is that the IP of the printer?



For what it's worth, even if it is, browsing to that IP may not do you
any good.  They may simply have the printer listening, without
providing
any interface.  That's what my HP LaserJet 4M does (it's there on the
network, listening and printing, but doesn't provide any kind of
interface to the outside world).


Exactly. It does not let me browse.


Is that the IP of the router?


The printer's IP is the same as the wireless router (i.e. 172.16.100.1 
and the Linux system is 172.16.100.x)



In that case, I'd expect that the router is acting as an internet
printing server, and ought to have some kind of interface.  But
you may
have more luck going to the root of the server (instead of directly to
the printer address), , to see if that gives
you an interface.

Tried that also, and it did not show anything on the browser. The 
process list on the DLink Router shows a program named ippd running 
which provides the interface to the printer.



Can you access the router's print server port via telnet?

telnet 172.16.100.1 631

If not try disabling the Fedora's firewall.

Also, last week i had a problem with a customer, and it was he 
configured a wrong net mask in the Linux box.


I suppose that ping and traceroute to the printserver's IP give the 
expected results, did you tried it?

Did you install tftp-server? ( yum install tftp-server )

What mode did you set the files in tftpboot?

Re: httpd fails to start

On a newly installed F24 I have a /home/... directory with a
collection of movie files - *.m4v and such, that I want to googlecast

this directory listing when the local machine name is entered in the
address line of google-chrome, and when a file is clicked, it plays
and can be "cast" to the TV.  Neat!

However, when the machine boots (quiet, without rhgb) the messages
include
   [FAILED] Failed to start The Apache HTTP Server.
   See 'systemctl status httpd.service' for details.
and, sure enough, httpd isn't running.

journalctl -b shows this:

   Jun 27 10:33:17 garfield systemd[1]: httpd.service: Failed with
   result 'exit-code'.

It can be started manually later, readily enough, with
   systemctl start httpd
but that's a PITA.

So, why could httpd not
   "make_sock: could not bind to address 192.168.10.99:80"
Could it just be that the network isn't up yet?
Why isn't httpd more patient and persistent?

This seems like yet another systemd problem.
Can anyone suggest how to fix this?

Perhaps this helps you (search in this link for
