[opensuse] sshd.service (openssh) fails on boot when primary listener is a bridge (br0) instead of real interface (eth0). What dependency is needed?

Hi, opensuse 13.2's openssh /usr/lib/systemctl/systemd/sshd.service has a After=network.target dependency. When a real ethernet interface, eth0, is the primary 'net listener, cat /etc/sysconfig/network/ifcfg-eth0 STARTMODE='auto' BOOTPROTO='static' IPADDR='192.168.1.1/24' sshd, listening on 192.168.1.1, has no problems on boot. But, if I switch to using a bridge interface, br0, with eth0 as the real interface assigned to it, cat /etc/sysconfig/network/ifcfg-eth0 STARTMODE='auto' BOOTPROTO='none' cat /etc/sysconfig/network/ifcfg-br0 STARTMODE='auto' BOOTPROTO='static' BRIDGE='yes' BRIDGE_PORTS='eth0' IPADDR0='192.168.1.1/24' sshd fails on boot journalctl -b | grep -i sshd ... Apr 10 15:30:49 xen01 sshd[1345]: error: Bind to port 22 on 192.168.1.1 failed: Cannot assign requested address. ... Apparently, network.target 'waits' for *real* interfaces only. Once at the shell, br0 is fully up. sshd can be started, and it functions normally. What specific dependency can I add to the sshd unit to get it to wait for br0 being fully up?

[opensuse] Trying out wordpress - can't install a theme?
by Greg Freemyer 10 Apr '15

10 Apr '15

All, Is there write-up for how to get wordpress to run and allow themes to be installed in opensuse? == my status == Wordpress is in the server:php:applications repo so I installed it. I've hit 2 errors so far, and still can't install a theme: - Issue one: mod_php5 not enabled Solution: a2enmod mod_php5 (or can be done via yast) That allows basic wordpress to run and new posts to be made. The first thing I tried after that was installing a theme. - Error when trying to install a theme: "There are no HTTP transports available which can complete the requested request." Solution I used: zypper in php5_curl - Exposes a second error when trying to install a theme: === Downloading install package from https://downloads.wordpress.org/theme/guardian.2.0.zip… Unpacking the package… Abort class-pclzip.php : Missing zlib extensions === I haven't found the fix for that yet, but I'm surprised to hit these issues trying to get a popular package to work.

[opensuse] After fixing bridge interface activation on boot, wicked slows down boot time significantly?
by lyndat3＠your-mail.com 10 Apr '15

10 Apr '15

I'm running opensuse 13.2. For running Xen, I need a bridge interface. To get the network bridge to be activated on boot, you have to enable wicked-nanny /etc/wicked/common.xml - <use-nanny>false</use-nanny> + <use-nanny>true</use-nanny> It's a known bug that say's "fixed" by a new wicked release. I'm not seeing it https://bugzilla.novell.com/show_bug.cgi?id=911562#c21 After enabling nanny, boot takes noticeably longer. It's due mostly to wicked systemd-analyze blame 44.082s wicked.service 3.745s lvm2-activation-early.service 1.101s lvm2-activation.service ... journalctl -b | grep -i wicked Apr 10 11:27:46 xen01 wickedd-dhcp6[1261]: Using netlink event receive buffer of 1048576 bytes Apr 10 11:27:46 xen01 wickedd-dhcp4[1262]: Using netlink event receive buffer of 1048576 bytes Apr 10 11:27:46 xen01 wickedd-auto4[1263]: Using netlink event receive buffer of 1048576 bytes Apr 10 11:27:46 xen01 wickedd[1283]: Using netlink event receive buffer of 1048576 bytes Apr 10 11:27:46 xen01 wicked[1305]: eno1: configuration applied to nanny Apr 10 11:28:23 xen01 wicked[1305]: br0: configuration applied to nanny Apr 10 11:28:23 xen01 wickedd[1283]: br0: successfully verified address '192.168.1.1' Apr 10 11:28:24 xen01 wickedd[1283]: br0: successfully notified about address '192.168.1.1' Apr 10 11:28:29 xen01 wickedd[1283]: br0: No duplicates for IP address 192.168.1.1 detected Apr 10 11:28:29 xen01 wickedd[1283]: br0: Notified neighbours about IP address 192.168.1.1 Apr 10 11:28:30 xen01 wicked[1305]: lo: configuration applied to nanny Apr 10 11:28:30 xen01 wicked[1305]: Interface wait time reached Apr 10 11:28:30 xen01 wickedd[1283]: ni_process_reap: process 1583 has not exited yet; now doing a blocking waitpid() Apr 10 11:28:30 xen01 wickedd[1283]: lo: address 127.0.0.1 covered by a static lease Apr 10 11:28:31 xen01 wickedd[1283]: lo: address ::1 covered by a static lease Apr 10 11:28:33 xen01 wicked[1305]: lo device-unconfigured Apr 10 11:28:33 xen01 wicked[1305]: eno1 enslaved Apr 10 11:28:33 xen01 wicked[1305]: br0 up I'd like to have both (1) br0 up on boot (2) an improved boot time, reducing wicked's 'wait' What config changes need to be made to get both?

Despite anything that basic may say, having a /boot partition, especially as a primary rather than on LVM is an excellent idea and adds greatly to the resilience and manageability of your system It should be part of the default installation. > What's wrong with C?

[opensuse] Manually checking ext4 file system for any errors
by Basil Chupin 08 Apr '15

08 Apr '15

In a galaxy long ago one could boot into openSUSE by putting level 1 in the boot command and login as root after which you could manually check for any errors in the ext3 or ext4 file system by issuing the following commands: mount -o remount, ro /dev/<hdX>/<sdX> followed by e2fsck /dev/<hdX>/<sdX> and, if errors were found, follow the prompt(s) to have any errors repaired. A few minutes ago I tried this on the laptop which has Tumbleweed installed on ext4 file system (I didn't want to this experiment on my main system on the desktop). Booting into level 1 seems to be OK and logging in as root was OK but then when I issued the command- mount -o remount, ro /dev/sda5 [#] I got the response (error msg) that- mount: / is busy The above sequence of commands worked for years in SuSE and then openSUSE so why has it now stopped working? Or put another way, how does one go about manually checking the file system for errors by running "e2fsck"? Why run "e2fsck" manually you may ask? Because I have found that the checking which is done automatically after X number of boots by the built-in system does not always pickup the errors in the ext3/4 file system. (Don't try to convince me otherwise because I have proven that to myself several times over the years. In any case, this is not the point. The point is why I now cannot check the file system using the method above which was spelt out in detail in the Administrative Manual which came with the version of S.u.S.E.?) Can anyone please give details on how now to manually check the ext3/4 file system for errors? [#] sda5 is where / of TW is installed.

[opensuse] default routeS post-13.1
by Felix Miata 08 Apr '15

08 Apr '15

[13.2 and Tumbleweed, with Wicked; no wireless; 1 interface per host] Googling 'site:opensuse.org sdb: network" produces nothing containing string "wicked". 'site:opensuse.org sdb: network wicked' produces nothing containing string "sdb:". https://en.opensuse.org/Portal:Wicked contains nothing obviously about configuration in its few listed topics. Now that the old ways have been replaced with Wicked, search results are even harder to sift through, assuming one can get onto the web in the first place... Can more than one default route per interface be configured? If so, where? /etc/sysconfig/network/ifroute-<interface> ??? /etc/sysconfig/network/routes ??? elsewhere ??? If not, which file or files must be changed to contain the relevant GW IP? I configure my own installations with fixed IP. I want to be able to take any of them elsewhere, discover the IP of the relevant gateway/router, and using mcedit, change, or add, whatever is necessary, without starting any GUI, YaST, or any kind of "manager". Is this asking too much? I tried this several hours ago. Getting/using an IP was no problem. Working DNS was no problem. Never could get a default route into a routing table. 'route add default gw <IP>' didn't do anything regardless of what I tried changing in /etc/sysconfig/network/. What else I tried I cannot remember. :-( Same machine I specially preconfigured before leaving here with an additional 13.1 with DHCP. So when I left here, I had 1 DHCP and 3 fixed IP openSUSE installations that worked. Routing worked there in 13.1 with DHCP initially (e.g. success to ping www.google.com), but never again after lost Dlink DIR-655 router password required doing a hard reset, which reset its IP to its default 192.168.0.1. Afterward, no matter what I booted, if ifconfig -a showed a properly configured interface, I could reach the router and login with Firefox, and I could ping the router, but I could not ping www.google.com ('no route to host', among other observed failures, such as no reaction at all, depending on which OS booted). I gave YaST2 a try in either 13.2 or TW, but it didn't give me a working GW either. :~( -- "The wise are known for their understanding, and pleasant words are persuasive."

[opensuse] How to add a package-specific, post-update-or-install script hook to a zypper action?
by lyndat3＠your-mail.com 08 Apr '15

08 Apr '15

I'd like to add a hook to zypper install/update. Whenever any or all of a specific set of packages blah blah-tools blah* is updated, I want to run a script after the installs are complete and successful sh ~/scripts/somescript.sh I took a look at Extending ZYpp: Plugins and Hooks https://doc.opensuse.org/projects/libzypp/HEAD/zypp-plugins.html but don't see, or maybe understand, how that applies to my case. Is there a straightforward way in opensuse/zypper to trigger a script whenever a specific package is installed or updated?

[opensuse] BTRFS barfed up my filesystem
by John M Andersen 07 Apr '15

07 Apr '15

Couple weeks ago I went on vacation. In preparation, I backed up laptop, and shut it down, (powered off). Today, I get back, fire it up, and the root file system (btrfs) will only mount in read-only mode. So I boot up with an install CD in recovery mode, run a btrfs check, and get a screen scroll of over 2500 files with reference counters of zero. The system will boot, but locks up shortly there after, and often with a watch dog timer indicating that one or the other of the CPUs locked up. (sometimes 0, sometimes 1). I can't seem to find any Google foo to repair that file system, so tomorrow I will nuke the thing, reinstall (I'm done with BTRFS, I never saw any benefit from it) and restoring from backups which I took just before vacation. This is the third time BTRFS crapped all over my machine and it seems very fragile to me while providing very little benefit, and a whole lot of ambiguity as far as disk usage, free space and the recover options seem pathetically immature. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] systemd-journal: Forwarding to syslog missed 1 messages. ?
by Per Jessen 07 Apr '15

07 Apr '15

This is a brand new 13.2+updates system - a desktop that isn't even being used. I have syslog-ng 3.6.2. According to 'man journald.conf', the default is to have 'ForwardToSyslog=yes', but with barely messages flowing (it's mostly "Forwarding to syslog missed x messages."), why are they missed? Besides, I guess this forwarding isn't needed when syslog-ng and systemd communicate using /run/systemd/journal/syslog ? -- Per Jessen, Zürich (4.1°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] basic apache2 / php config question
