IP address or DNS name (bug or feature)
by Walter H.
Hello,
as this is the first time I'm using Fedora, I noticed the following ...
(a) when open a SSH connection, it tells e.g.
Last login: Mon Jun 5 20:14:37 2017 from 192.168.1.1
all other Linux VMs and/or the Router box show there
Last login: Sat Jun 3 21:41:45 2017 from winpc.local
(b) when configuring Firefox using a proxy, this works only
when entering a IP address; when entering a DNS name
a 'Proxy server not found' error is the result ...
(c) when configuring a line printer I had to enter e.g. this
lpd://192.168.1.11/CP1515N
when entering a DNS name e.g. printer.local
then this result in a 'printer.local' could not be found;
a nslookup shows the correct IP addresses
this means the DNS server is working properly ...
Thanks for explanations,
Walter

by jayshankar nair
Hi,
I have written a snippet of code to generate core dump.
a.c#include <stdio.h>main(){char **c;c=10;
}
gcc a.c -o a -g
Run:./a
In fedora 25 after segmentation fault, core dump file is not being created.
I have also set the core file to unlimit with the command ulimit -c unlimited.
Thanks,Jayshankar

The SMS data is in a protected directory on Android phones. I believe
the call logs are as well. Unless your phone is rooted, you won't have
access to them. There are utilities out there in Android-land that will
let you back up SMS data and call logs, or you can root your device.
>From what I can remember, the SMS data is in
/data/data/com.android.providers.telephony/databases/mmssms.db
on the phone. Unless you're rooted, /data reports as an empty directory.
Android is essentially saying "Nah, it isn't empty, but you ain't root
so you can't see what's here. So there! Nyah! Thhpt!" <insert emoji
with a thumbed nose here>
There are times I absolutely hate Android. It's my phone. I should be
able to do what I want with it. Why the hell can't I move stuff to and
from my SD card as I see fit? Truly annoying.
This web site
https://www.maketecheasier.com/airdroid-connect-android-phone-to-linux/
says you can
# See Messages and Call logs
Not sure if that means I would be able to copy them to linux.

Update to libdb-5.3.28-21.fc25 in F25 will break the rpm database.
Repairable by rebuilding rpm database with rpm --rebuilddb
by stan
There is an update (or test update) of libdb for F25 that, when
installed, breaks the rpm database because it is incompatible. The dnf
update completes, and then hangs (at least it did on my system). The
fix is to remove the old rpm databases (this might be optional), and
rebuild the rpm databases.
rm /var/lib/rpm/__db.00? # optional?
rpm --rebuilddb
I did a reboot to sync everything that uses libdb (anything that uses
the Berkeley db). It might be possible just to restart affected
applications if that isn't an option. That worked for my mail client
before I rebooted.

postgresql and firewald startup
by Jeandet Alexis
Hello,
I have a server running F25 with postgresql and firewald configured.
On startup postgreslq always fail to start complaining about port 5432.
I did allow this port on the firewall, if I start manually postgresql
after it works.
So I did plot the startup sequence (systemd-analyse plot), I saw that
pgsql start after dbus.service but much before the firewall. Is there
something wrong with the default config of pgsql systemd unit?
Or more likely, what did I miss? mess :)?

Using mrtg to monitor cable modem utilization
by Alex
[first time went without a subject somehow...]
Hi,
Anyone still using mrtg these days? I'm trying to set up mrtg on my
fedora25 system connected to a cable modem (35Mbit up, 5Mbit down) on
one side and a gigabit ethernet on the other and can't figure out how
to reflect that in the config file.
Maybe you have an idea for monitoring utilization using another method?
I'm trying to set it up to determine utilization, so it's important to
define the upper bound for both upload and download. Is this possible?
If I recall, isn't there a way to define input max and output max?
I've run the following cfgmaker command:
# cfgmaker --ifref=descr --ifdesc=alias -zero-speed=5000000
mysnmppass(a)orion.example.com
Here is the ifconfig output for my system. I've also included the
generated cfgmaker output (with 'example' as my domain) below. I don't
understand why it's defined eth0 and eth1 as 125MBit when it's
connected to a bridge on a gigabit network, and why it's chosen
625kbit for br0 when I've tried to define it as 5Mbit.

Seem to have screwed my F25......
by DB
Evening all,
I thought it would be a Good Idea to "improve" my Fedora system if I
added an SDD.
I put it in, plugged it in & it seemed to work - sort of....
What I now have is a selection window from grub which has 2 new versions
of F25 Workstation (on sda), then an F19, also on sda, followed by the
F25 on sdb (my SDD).
What I would like to do is to remove the 2 new F25s because the one was
only stated to allow me to boot the system; remove the F19 & put F25 on
sdb as the default. I hope that doing something like this would mean
that (system) updates would be applied to the SDD F25, and that I would
be able to access all the software I have on /home......
Does anyone have any ideas how I might be able to do this???
Would I need to change any of my SATA cables to make sdb into sda???
Many thanks for any suggestions!!!!!

2 mice: left & right handed
by andrea
Hi,
running F25 GNOME on Wayland and have 2 mice.
One on the left and one on the right of the keyboard.
I would like to set the left as left handed and the right as right handed.
In GNOME settings I cannot change it per mouse, rather for all of the at the same time.
I read that this is a libinput matter, but I cannot find how to do it.
Any suggestions?
