dnsmasq won't start
by Patrick O'Callaghan
For some reason I'm getting this:
$ systemctl status dnsmasq
● dnsmasq.service - DNS caching server.

Can't figure out what is sitting on port 53 (the DNS port). I'm not
running bind.

Cross compilers, but not libraries?
by Tom Horsley
In fedora 23, there are cross compilers available in the repos.
For example:
gcc-aarch64-linux-gnu.i686 : Cross-build binary utilities for aarch64-linux-gnu
gcc-c++-aarch64-linux-gnu.i686 : Cross-build binary utilities for
: aarch64-linux-gnu
binutils-aarch64-linux-gnu.i686 : Cross-build binary utilities for
: aarch64-linux-gnu
But, there are no cross libraries apparently. Is there some
standard way people get libraries for cross development?

Hylafaxm without modems - SIP?
by Gary Stainburn
I've just had to replace my Hylafax server as the cooling fan in the rack case
has died and could not be replaced.
My box runs three fax modems, one for each of the original 3 fax machines that
got skipped years ago.
This means that I now have 3 lots of:
USB to seral converter (new box doesn't have any COM ports.
9pin->25-pin serial cable
Modem
power supply
phone line
analogue port on our Mitel 3300 controller
I was wondering if there a better way?
I've done lots of Googling and there is a lot of conflicting - and mostly very
old - information out there.
Does anyone have any more up-to-date opinions or advice on doing this?
Most of the concerns about reliability were based on IP latency, but my fax
server and my Mitel controller are both on the same Procurv Gigabit switch so
hopefully that would be quick enough

how to automatically clean /tmp
by Walter Cazzola
Dear Linux Experts,
I've recently passed from Fedora 20 to Fedora 23 on my laptop.
I've a separate partition for /tmp that I'm used to see it wiped out at
any reboot on my previous installation but now this is never wiped out.
This is a real partition:
/dev/sda10 5029504 1154204 3596772 25% /tmp
whereas previously it was a tmpfs partition. I've read on the web that
after Fedora 20 the tmpfs has been dropped in favor of real partition
but I was expecting anacron/cron entry that wipe the content of the
partition at boot but my system doesn't have any.
It is also difficult to create my own anacron/cron entry because this
should take effect before the system starts and create its temp
files/sockets in there.
I'm also puzzled because I also have a couple of tmpfs partitions:
tmpfs 1633640 0 1633640 0% /run/user/989
tmpfs 1633640 16 1633624 1% /run/user/526
that I don't what they are for and if I can (and how) rid of them.
Probably I could add an entry like this
tmpfs /tmp tmpfs rw,seclabel 0 0
in /etc/fstab but this would means a waste of the space I currently have
reserved for /tmp (4Gb not much but I would prefer to use them).
So there is a way to wipe out the /tmp partition before it has been
mounted and the system creates its files and use the current partition
for it?
Thank you
Walter

Thunderbird doesn't accept password/username
by Martin S
Hi,
Before the community sighing begins.
Yes I've double, triple and quadruple checked that the setting to the
server are correct.
And googled umpteen hits starting with Account can
not be verified - most of them telling me GMail changed their login
routine ...
No, it's not a Gmail account, it's a regular mail server.
Yes, other clients (Evolution, KMail) are able to connect and yes I've
tried accessing my mail account through webmail.
I still get "Account can not be verified - are you sure your username
or password are correct" in Thunderbird.
Any ideas before I apply to the loony bin?

GNOME Extensions for time/date and autologin
by Alex
Hi all,
Does anyone know of a GNOME extension (fedora23 desktop) to control
the date/time in the top menubar thing to change it to 12-hr time
instead of 24-hr? Is an extension even necessary for that, or am I
missing some other ability to control that?
Is there an extension that enables autologin? I'd like to save my
password and have it login automatically, since it's only my desktop
with no other users.
Any other extensions you think are really useful you might recommend?
Thanks,
Alex

selinux??
by bruce
Hi.
In testing out creating/setting up remote droplets on digital
ocean/fed (centos), I realize that it should be secured as
much/tightly as possible. However, I also realize that if I screw
something up, I could have an instance that has issues. I'm not a sys
admin, and not trying to be one.
So, here's my question. If I'm going to be spinning up/down an
instance, could I simply disable selinux? For my scenario, I'll be
creating a base instance, with the required apps/processes, and then
using that base instance for any testing droplets I need to create, to
test my apps.
So, if I create an instance, spin it up, fire off my tests on the
instance, run everything for a few hours, and then shut it off, would
that be "reasonably safe/secure"?
My testing apps are a mix of python/php/perl/shell scripts, there's no
web stuff as of yet. Although, there will be dns/nfs/mysql
functionality.
Thanks for thoughts..

Postfix settings issues
by arnaud gaboury
I am running Fedora 23 server. Among other services, I want to deploy
a mail server with postfix.
1- I registered on my DNS provider a A and MX records:
------------------------------------------------
mail.thetradinghall.com. 86400 IN A 212.147.52.214
thetradinghall.com. 86400 IN MX 10 mail.thetradinghall.com.

2- tested with dig
-----------------------------------------------------
$ dig mail.thetradinghall.com @ns1.he.net
;; ANSWER SECTION:
mail.thetradinghall.com. 86400 IN A 212.147.52.214
$ dig thetradinghall.com mx @ns1.he.net

Nothing set in a first step as for TLS./etc/postfix/master.cf is the

No entry in iptables, as until now, I let it permissive :
# iptables -L
----------------------------------------------------------
Chain INPUT (policy ACCEPT)
target prot opt source destination
f2b-pam-generic tcp -- anywhere anywhere
Chain FORWARD (policy DROP)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain f2b-pam-generic (1 references)
target prot opt source destination
RETURN all -- anywhere anywhere
-------------------------------------------------------
Now when testing with telent, I don't have the answer expected :
220 mail.thetradinghall.com ESMTP Postfix
$ telnet mail.thetradinghall.com 25
Trying 212.147.52.214...
Connected to mail.thetradinghall.com.
Escape character is '^]'.
-------------------------------------------------
I must have misconfigured something, but I have no idea what. After
lots of reading, it seems to me the setup is correct.
Thank you for any hint.
