currently I perform operations between different computers in my local
network using open SSH; however, when I do this, I always use the
computer's IP number to reference the host. (ex: sudo ssh
I'm wondering without yet finding an answer how to do the same thing using
(instead of the IP address) the name of the computer ..
Do I have to Installase BIND? And then what else is needed? ...
thanks for every suggestion
So, after upgrading the RAM in my Lenovo ThinkPad T-420 I thought I'd get
faster performance. But even with two 8GB sticks?....it's running even
SLOWER?! Is there something I've done wrong? It's got a 320GB 7200RPM hard
drive....and it's running F30. Funny thing is? .....before the upgrade it
had just 8GB of RAM (two 4GB sticks) and seemed to run smoother and faster.
Is there anything I can check to find out what the problem could be?
The upgrade to Fedora-30 is done. This included upgrading Thunderbird
to version 68.1. Unfortunately, this also lost all preferences,
calendar data, set-up, filters, etc.
Fortunately (I hope!), I did back up my ".thunderbird" directory before
doing the upgrade. I seriously need my e-mail filters and my calendar
(lightning?) data. How do I restore those?
Fedora 30 x64
Did I typo something here? This happens on more
than one stick.

What did I do wrong?
We shuffled some systems around at work. An NFS server now has
a new IP address. On my fedora 30 desktop I see:
nslookup <server> shows the new IP address
host <server> shows the new IP address
ping <server> still pings the OLD address!!!
mount /mountpoint apparent still uses the old IP because it times out.
I'm not running nscd. I'm not running systemd-resolv. I'm
not running dnsmasq or bind as a local cache. I don't have
entries in /etc/hosts for the old IP.
So where is this "helpful" cache that has the old
Hi! Does anyone have any idea why there is such situation:
[root@localhost ~]# systemd-analyze blame | grep tables
This is on a new nvme laptop but the same behavior is present on any
other systems that i have (but annoying on the laptop)
The overall situation is :
[root@localhost ~]# systemd-analyze
Startup finished in 2.070s (firmware) + 5.323s (loader) + 837ms (kernel)
+ 1.218s (initrd) + 2.067s (userspace) = 11.517s
graphical.target reached after 1.160s in userspace
Does anyone have an idea how can i speed up this? (firewalld usage is
not good for me)
I have a LAN using CentOS and Fedora installations (currently its
CentOS 7 on the server). At times it insists on doing double-sided
printing, and will not let me choose single-side. Erratically the
option is either unavailable (the drop down menu is not clickable, and
says "not available"); or when the option is responding, my selection
is ignored; and some days it works properly. The printer is a HP
LaserJet P3015. I get this erratic behaviour on any of the PCs, and it
used to do this, too, when the server was previously a Fedora install.
Anybody have any clues?

With one of my computers I have problem to set permanent default start
order of the kernel. I can change it with "sudo grub2-set-default 0" but
when I update the kernel I get oldest kernel as default boot order.
How do I make the start order so the latest kernel is default?
