dnsmasq won't start

For some reason I'm getting this: $ systemctl status dnsmasq ● dnsmasq.service - DNS caching server.

Cross compilers, but not libraries?
by Tom Horsley 28 Jan '16

28 Jan '16

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 28 Jan '16

28 Jan '16

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 28 Jan '16

28 Jan '16

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 28 Jan '16

28 Jan '16

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? /Martin S -- This address is for technical mail lists only.For all other matters, please use my main addressat the .org domain.

GNOME Extensions for time/date and autologin
by Alex 27 Jan '16

27 Jan '16

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 27 Jan '16

27 Jan '16

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..
