F29 Wail at the Firewall (long; sorry!)
by Beartooth 12 Dec '18

12 Dec '18

In the words of the starlet, I try to be cynical [read paranoid] about security, but I just can't keep up. I do some of my email and all of my Gmane activity (including this list) at the address above, from my local access provider, Comcast; but I do most of my email (and my wife does all of hers) at my own domain, to which we connect by ssh. Recently we've been moving machines about physically, from floor to floor and connection to connection. We've also been getting lots of timeouts. When I asked my domain host about it, he told me it was my own firewall cutting us off. It blocks connections out from our IP address if they fail more than it likes. I read -- no, I study, hard -- whatever security news comes across lists and sites I follow; I usually think I understand, more or less, what the hazard is. I think so this time. It seems the current default firewall is harder-nosed about failures to connect than it was; afaict, *we* are doing little if anything different. But in all my years running Linux (since RedHat 7), I have not become savvy about writing nor editing code, any more than I've become a motor mechanic by driving (since about 1955 or so). I understand that it is necessary to throttle any malware that might try to call home; so I shouldn't just comment out whatever does the blocking, even if I knew where it was. So, I THINK, I ought to enlarge a/o lubricate the opening in the firewall that lets US out, but not make it any easier than I can help for supposed malware to get out. Does that make sense? If so, where do I go (i.e., what file do I open), and what changes do I make, to accomplish that? -- Beartooth Codger, Not Quite Clueless Remember I know little (precious little!) of which way is up.

Strange uptime behavior under qemu-kvm
by Sebastian Himmler 12 Dec '18

12 Dec '18

Hi all, I've experienced some strange behavior on Fedora 28 client systems. I have some of them virtualized on a qemu-kvm hypervisor. All these systems take the hypervisor uptime as their own. This is really annoying, since I can not determine how long a host is up. If I take a look in the boot log I can see this: ...snip... [ 0.000000] Hypervisor detected: KVM [ 0.000000] kvm-clock: Using msrs 4b564d01 and 4b564d00 [137891542.045328] kvm-clock: cpu 0, msr c6c01001, primary cpu clock [137891542.045329] clocksource: kvm-clock: mask: 0xffffffffffffffff max_cycles: 0x1cd42e4dffb, max_idle_ns: 881590591483 ns ...snap... Is there any possibility to turn this off, so that the VM takes its own uptime? Really much thanks for any solution / suggestion! Sebastian

Anyone else have occasional nvidia crashes?
by Tom Horsley 12 Dec '18

12 Dec '18

I have a GeForce GTX 750 Ti in my system at work, using the rpmfusion nvidia drivers (because nouveau can't go more than a few hours without crashing). Every so often, when the X server starts or is restarted by logging out, the screen will go blank and the system will be frozen, needing a power cycle to get it back. This only happens at work, a very similar system at home with a newer model nvidia card never has this problem (though it certainly had the same crashes under nouveau). Just curious if anyone else with the 750 Ti has seen similar symptoms.

[F29] Command dvipdfmx (texlive) does not work
by Marco Guazzone 11 Dec '18

11 Dec '18

Hi, On my Fedora 29, the command dvipdfmx does not work: $ rpm -q texlive-dvipdfmx texlive-dvipdfmx-20180414-28.fc29.x86_64 $ dvipdfmx bash: dvipdfmx: command not found Indeed, the executable file '/usr/bin/dvipdfmx' is a broken link that points to a nonexistent file: $ ls -al /usr/bin/dvipdfmx lrwxrwxrwx. 1 root root 9 Nov 26 19:22 /usr/bin/dvipdfmx -> xdvipdfmx $ ls -al /usr/bin/xdvipdfmx ls: cannot access '/usr/bin/xdvipdfmx': No such file or directory I tried to reinstall the texlive-dvipdfmx package with no success. I already filed a bug: https://bugzilla.redhat.com/show_bug.cgi?id=1657755 I would like to know if some of you has this problem too, and if (s)he already found a workaround. Thank you in advance for your help. Best, Marco

Can't boot kernel-4.19.6-200.fc28.x86_64

11 Dec '18

Folks, this morning I rebooted one of my systems. The system ended up dropping into emergency mode. I ran journalctl -xb to see why it failed to boot and I saw the following errors: Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol gfn_to_memslot (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol vfio_pin_pages (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol vfio_info_cap_shift (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol vfio_set_irqs_validate_and_prepare (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol vfio_device_put (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol gfn_to_pfn (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol mdev_from_dev (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol kvm_put_kvm (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol kvm_write_guest (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol kvm_slot_page_track_remove_page (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol kvm_page_track_register_notifier (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol mdev_parent_dev (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol vfio_unpin_pages (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol kvm_is_visible_gfn (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol kvm_page_track_unregister_notifier (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol vfio_device_get_from_dev (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol kvm_slot_page_track_add_page (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol vfio_register_notifier (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol vfio_info_add_capability (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol mdev_get_drvdata (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol mdev_register_device (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol mdev_dev (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol mdev_unregister_device (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol vfio_unregister_notifier (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol kvm_read_guest (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol mdev_set_drvdata (err -2) Dec 11 08:02:46 terrapin kernel: kvmgt: Unknown symbol kvm_get_kvm (err -2) I'm sure I booted up on 4.19.6 on this system before without errors. In fact my other system is running 4.19.6 so what might have changed to cause this failure? The system booted fine on 4.19.5. Any help is appreciated. Thanks, Paolo

Mysqld refuses to start after upgrade to Fedora 29
by Danny Horne 11 Dec '18

11 Dec '18

Hi all, Hope I can find an answer here because I don't know where else to ask. I've just upgraded from Fedora 28 to Fedora 29 and mysqld (version 8.0.13) won't start. There's nothing useful in the logs so I've no idea where to look for a solution. Was working fine in Fedora 28. Thanks for looking

Install on Zotac Zbox CI327?
by wwp 11 Dec '18

11 Dec '18

Hello there, (after a looong time not using Fedora, just back to it!) I've tried installing Fedora on a Zotac Zbox CI327 (Intel Celeron N3450 inside) but this happens to fail. I've tried F25 but it has not the right kernel to make it (I've read about 4.10 minimum), then tried F26-Alpha-1.7 Live and Rawhide-20170518 Live but none could reach the graphical login. They both boot, some steps take a lot of time and I end up in a state I don't understand but which is not friendly ;-). Here's a link to a rdsosreport.txt file generated using Rawhide, I must admit that I don't know what to do now.. https://paste.fedoraproject.org/paste/iRx8d~7Luk2TC3bsaDuuT15M1UNdIGYhyRLiv… BTW, I could install and run a Ubuntu 17.10 daily (artful-desktop-amd64-20170519.iso) - wow it starts up pretty quickly - and that gave me hope! Any hint or experience w/ such hardware? Regards, -- wwp

How do I : one static DNS , one from DHCP ?
by sean darcy 11 Dec '18

11 Dec '18

FC28. I'm running a DNS server (unbound) on a VOIP server. It's crucial that I can always resolve addresses, even if it's slower. Now DNS1 is set to 127.0.0.1, peerdns no. Giving: cat /etc/resolv.conf # Generated by dnssec-trigger-script nameserver 127.0.0.1 What I want is: nameserver 127.0.0.1 nameserver <whatever dhcp gives> Any help appreciated. sean

by François Patte 11 Dec '18

11 Dec '18

Bonjour, The last kernel 4.19.6-300.fc29.x86_64 on my f29 does not boot: after a long stop at "reached target basic system", the boot stops with this message (repeated many times): dracut-initqueue timeout starting timeout scripts then an emergency shell is opened then what can I do? Thank you. -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)6 7892 5822 http://www.math-info.univ-paris5.fr/~patte

Selinux problem -
by Bob Goodwin 10 Dec '18

10 Dec '18

. I just upgraded this Fedora 27 to 29 and it refused to run xfce until I "setenforce 0" I never seem to have selinux problems and don't know how to deal with them. Doing "ausearch -m avc" produces a slew of: ---- time->Mon Dec 10 17:10:06 2018 type=AVC msg=audit(1544479806.790:376): avc: denied { dac_override } for pid=5795 comm="gmain" capability=1 scontext=unconfined_u:unconfined_r:thumb_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:thumb_t:s0-s0:c0.c1023 tclass=capability permissive=0 ---- I think they are all the same?
