No wayland on Intel HD graphics?
by Tom Horsley 26 Sep '17

26 Sep '17

I was installing fedora 26 workstation on a little Intel NUC system last night (specifically model NUC5CPYH). It uses "Intel HD Graphics" and anaconda worked fine, but once I booted f26 from hard disk, the screen just went gray and stayed there. When I installed xdm and switched the login from gdm to xdm, I was able to get a login prompt and run gnome (I'm pretty sure in X since I'm guessing xdm probably doesn't know how to start wayland). Is this a known bug? Should I report it against some component (which one?)

DNF undo
by ogio spam 26 Sep '17

26 Sep '17

Hi all, I have a lot of problems with my fedora 26 installed on a Dell laptop model Inspiron 15 7000 gaming. I use KDE so I installed the KDE version for fedora. I stopped upgrade kernel because it won't work with the new 4.12 So I start with 4.11.11 It was ok until today. I run dnf update, checked that nothing related to the kernel 4.12 was updated, and confirmed all. Now it boot in init 5 but no graphics displayed after the fedora logo. I was able to switch to the second console and issued an init 3 After that I logged with my user, and startx was ok. I had some other problems related to Network Manager (my card is not seen), and so on. So I would like to undo the upgrade. There is a possibility to do it? Regards Ambrogio

I'm trying to configure fail2ban and it appears as if it is correctly identifying addresses to ban however it doesn't appear to be successful in banning hosts: 2017-09-24 16:01:46,073 fail2ban.actions [3591]: NOTICE [sshd] Ban 91.210.178.96 2017-09-24 16:01:46,494 fail2ban.action [3591]: ERROR ipset add fail2ban-sshd 91.210.178.96 timeout 31536000 -exist -- stdout: b'' 2017-09-24 16:01:46,494 fail2ban.action [3591]: ERROR ipset add fail2ban-sshd 91.210.178.96 timeout 31536000 -exist -- stderr: b'ipset v6.29: The set with the given name does not exist\n' 2017-09-24 16:01:46,495 fail2ban.action [3591]: ERROR ipset add fail2ban-sshd 91.210.178.96 timeout 31536000 -exist -- returned 1 2017-09-24 16:01:46,495 fail2ban.actions [3591]: ERROR Failed to execute ban jail 'sshd' action 'firewallcmd-ipset' info 'CallingMap({'ip': '91.210.178.96', 'failures': 25, 'time': 1506283306.0737438, 'matches': '2017-09-24T12:50:33.918187xyzzy.bubble.org sshd[31335]: Invalid user admin from 91.210.178.96 port 51448\n2017-09-24T12:50:35.229995xyzzy.bubble.org sshd[31337]: Invalid user admin from 91.210.178.96 port 51456\n2017-09-24T12:50:36.520259xyzzy.bubble.org sshd[31339]: Invalid user admin from 91.210.178.96 port 51461\n2017-09-24T12:50:37.869954xyzzy.bubble.org sshd[31343]: {removed part of the very long line showing all the matches in fail2 ban} 91.210.178.96 port 51705', 'ipmatches': <function Actions.__checkBan.<locals>.<lambda> at 0x7f3ed78c7950>, 'ipjailmatches': <function Actions.__checkBan.<locals>.<lambda> at 0x7f3ed78c7c80>, 'ipfailures': <function Actions.__checkBan.<locals>.<lambda> at 0x7f3ed78c7d90>, 'ipjailfailures': <function Actions.__checkBan.<locals>.<lambda> at 0x7f3ed78c7d08>})': Error banning 91.210.178.96 2017-09-24 16:01:46,909 fail2ban.actions [3591]: NOTICE [sshd] 91.210.178.96 already banned 2017-09-24 16:01:47,911 fail2ban.actions [3591]: NOTICE [sshd] 91.210.178.96 already banned This is Fedora 26 /etc/fail2ban/fail2ban.conf is set to distribution default /etc/fail2ban/jail.conf is set to distribution default I've added in to fail2ban.d/local.conf [fail2ban] enabled = true filter = fail2ban action = iptables-allports[name=fail2ban] logpath = /var/log/fail2ban.log # findtime: 1 day findtime = 86400 # bantime: 1 year bantime = 31536000 maxretry = 5 to jail.d/00-firewalld.conf [DEFAULT] banaction = firewallcmd-ipset sender = fail2ban(a)example.com destemail = root action = %(action_mwl)s to jaild/10-sshd.conf [sshd] enabled=true # findtime: 1 day findtime = 86400 # bantime: 1 year bantime = 31536000 and yes the system is currently setup to accept only public/private key authentication for SSH, I'm assuming that once I get ssh figured out I can get the other services figured out.

Tomcat - different users for different instances?
by Peter Boy 25 Sep '17

25 Sep '17

When Fedora used systemV init you could define a specific user for a specific tomcat instance in /etc/systconfig/tomcat-[myinstance] by adding a line TOMCAT_USER=„mytomcat“. In Fedora 26 with systemd you can define different Tomcat instances but the above mechanism doesn’t work anymore. I checked the starter script and couldn’t identify a way to define an instance specific user. Well, does anybody know how I can achieve this? My issue is: If my instances are all executing as the same user I get sometimes an „Too many open files“ error message and the instance stops executing. In RHEL it helps to define separate users per instance. The other instances were not affected by the broken one. Thanks Peter

Installing pandoc-crossref on Fedora 26 using Cabal
by Ankur Sinha 25 Sep '17

25 Sep '17

Hello, I've been trying to install `pandoc-crossref` on my Fedora 26 system using Cabal, but can't seem to do so. I've tried three different machines and get the same error on all. Would someone with some Haskell experience be able to help please? Here's the error. I've also filed the upstream but they haven't been able to help either.

Networkmanager openvpn and IPv6 address
by Ed Greshko 25 Sep '17

25 Sep '17

Has anyone tried making an openvpn connection with the gateway specified as an IPv6 address? It makes no difference if I give the IPv6 address as it, enclose it with the standard [ ] characters, or with quotes, the connection will fail immediately. If I give it a DNS entry which contains only an AAAA record it will work. Also, if I call openvpn directly with an IPv6 address in the config file it will also work. I think it is a bug in NetworkManager or I'm missing the magic incantation to specify the address in a way NM would be happy. -- Fedora Users List - The place to go to speculate endlessly

Build a network bridge with Fedora
by Cristian Sava 25 Sep '17

25 Sep '17

Hi all, Some of us choose to build Fedora servers (instead of using Centos, for vary reasons) with many virtuals, each with different IP. Everytime I have to follow these guidelines https://fedoramagazine.org/build-network-bridge-fedora/ So the question: Is there a tool to simply setup a bridge interface? Thanks Cristian Sava

Openvpn start fails on reboot
by Stephen Davies 24 Sep '17

24 Sep '17

If I reboot my F24 system, openvpn server fails to properly start but a subsequent manual systemctl start openvpn@server does succeed. The reboot log shows: Mar 5 11:52:51 mustang audit: SERVICE_START pid=1 uid=0 auid=4294967295 ses=4294967295 msg='unit=openvpn@server comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success' Mar 5 11:52:51 mustang systemd: Started OpenVPN Robust And Highly Flexible Tunneling Application On server. Mar 5 11:52:51 mustang audit: SERVICE_START pid=1 uid=0 auid=4294967295 ses=4294967295 msg='unit=openvpn@server comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success' Mar 5 11:52:53 mustang systemd: openvpn(a)server.service: Main process exited, code=exited, status=1/FAILURE Mar 5 11:52:53 mustang systemd: openvpn(a)server.service: Unit entered failed state.

It looks as if the automatic start may be happening too early in the boot process.

Fwd: [openFATE 322297] Yast2 working in wayland
by ChunYu Wang 21 Sep '17

21 Sep '17

Seems SuSE will start to support wayland with YaST :-) Really a good news. - ChunYu ---------- Forwarded message ---------- From: <fate_noreply(a)suse.de> Date: Thu, Sep 21, 2017 at 1:09 AM Subject: [openFATE 322297] Yast2 working in wayland To: opensuse-features(a)opensuse.org Feature changed by: Keith Hizal (kah0922) Feature #322297, revision 25 Title: Yast2 working in wayland openSUSE Distribution: New Priority Requester: Important Requested by: Andreas Winter (netzheimer) Requested by: Frederic Crozat (fcrozat) Requested by: Kai Dupke (kdupke) Partner organization: openSUSE.org Description: Wayland is coming with big steps. First distributions (eg fedora) already use it as default. Gnome should be already stable with it, Plasmas support is getting better and better. Some other DE already support it out of the box. Wayland is a lot more secure than Xserver and it is the future. I think it is time to bring Yast2's support for this. At the moment a user who wants to run wayland has just 2 solutions: - Running yast in textmode (which is not a solution for non-geek users) - Switch to another distribution, which offers better support There were already some bugs opened by opensuse users. So you see the feature is already needed. https://bugzilla.opensuse.org/show_bug.cgi?id=955101 Discussion: #1: Dominique Leuenberger (dimstar_suse) (2017-02-18 01:04:12) Just repeating here the workaround from the bug (so you have a VERY good workaround between your two options provided): xhost +LOCAL: This entire issue is not limited to YaST - but in fact ANY GUI application running as a different user (most likely root) #2: Frederic Crozat (fcrozat) (2017-02-20 16:50:39Z) (reply to #1) However, there is an interesting question here: why isn't YaST able to start in Wayland mode directly, since it is using Qt5. It should be able to run natively in Wayland and not requires X11.. #3: Frederic Crozat (fcrozat) (2017-02-21 13:55:20Z) (reply to #1) A "slightly" more secure way: xhost +SI:localuser:root This is equivalent to the current security model used currently on SLE12 / Leap. #4: Frederic Crozat (fcrozat) (2017-02-21 14:11:37Z) yast2 control center (Qt) or yast2 modules can be started in Wayland after installing libqt5-wayland and setting "QT_QPA_PLATFORM=wayland". But you need to be a regular user + #10: Keith Hizal (kah0922) (2017-09-20 17:09:30) + In the end xhost +SI:localuser:root is just a workaround and not a long + term solution. With Wayland not budging on running GUI apps as root, it + probably will be necessary run yast as a normal user and ask for the + root password once changes are made (possibly using polkit). -- openSUSE Feature: https://features.opensuse.org/322297
