Running local SSH as background process - possible??
by bruce 04 Oct '17

04 Oct '17

Ok guys, I know this isn't strictly "Fed" related, but the group might have suggestions. My use case, the process has a number of remote servers. I'd like to be able to run a bunch of commands on the remote servers as fast as posible. The initial thought was to loop through the different IPAddresses, and SSH into each server, to run the commands. However, this process was still "sequential" in that each SSH session needs to complete, prior to running the next server/ssh command. So, my question/need -- is to figure out how to run a ssh as a background on the local server. This approach would/should allow the process to quickly fire off commands to the remote ipaddresses/servers in a much faster/parallel manner. sortof: foreach iplist as ipaddress ssh user1@ipaddress command & (assuming that the '&' runs the local ssh in the background -- it doesn't!) Running "stuff" on the remote can occur in a "Screen" session, which would allow the ssh process to fire off the remote cmd, but it still doesn't run the local ssh as a "background" process.. Rick has mentioned/discussed the "Screen" function in past threads. Thoughts/comments....

ldbsearch and missing LDB_MODULES_PATH, how to set it correctly?
by Lin Pro 04 Oct '17

04 Oct '17

Fedora 27 libldb-1.2.2-1.fc27.x86_64 ldb-tools-1.2.2-1.fc27.x86_64 samba-dc-4.7.0-12.fc27.x86_64 Hello, I need to set LDB_MODULES_PATH=/usr/lib64/samba/ldb, so it can survive a machine reboot. Which package is responsible for that PATH anyway and how to find out? Right now here is what it is: ldbsearch -H /var/lib/samba/private/sam.ldb WARNING: Module [samba_dsdb] not found - do you need to set LDB_MODULES_PATH? Unable to load modules for /var/lib/samba/private/sam.ldb: (null) Failed to connect to /var/lib/samba/private/sam.ldb - (null) After the PATH is set things work OK. One could set a PATH in one of the .bashrc* files but I am afraid that the PATH is required by a process, not just a user. Thank for any hints. Lin

[F26] Cannot log in with sddm (Plasma), sddm-helper[6948]: segfault
by Frédéric Bron 03 Oct '17

Hi, Fresh install of F26. First user created in the installation process, no issue. 2nd user created with kuser from 1st user session. This second user cannot log in from sddm but he can log in from a terminal and run startx which works fine. Apparently, everytime he tries to login from sddm, we get this in dmesg: [ 8867.558759] sddm-helper[6948]: segfault at 0 ip 00007f141e369b1e sp 00007ffca5cf19f0 error 4 in libc-2.25.so[7f141e2f7000+1c7000] Frédéric

I give up using Fedora ...
by Walter H. 01 Oct '17

F25 was running fine; after upgrade to F26 my VMware was broken, now I have a VMware running with F26, which brings this: "This host does not support "Intel EPT" hardware assisted MMU virtualization. This host does not support virtualizing real mode. The Intel "VMX Unrestricted Guest" feature is necessary to run this virtual machine on an Intel processor. Module 'CPUIDEarly' power on failed. Failed to start the virtual machine." and the same machine runs the latest Win10 without problems(!) this machine is an old HP wkst xw4600 with a Core2 Quad Q9300 CPU and 4 GByte RAM Greetings, Walter

Radeon(Kaveri) missing firmware and lost HW video acceleration?
by lejeczek 01 Oct '17

01 Oct '17

hi fellas I think I've lost HW video decoding acceleration on A10 PRO-7800B R7 with recent kernel/mesa. My kodi was nicely using vdpau until recently, I cannot say when exactly it happened. Now only SW decoding and high CPU usage. I think I have all needed packages installed but vaapi also seems to be gone, when I do: [entertainer@swir ~]$ vainfo libva info: VA-API version 0.40.0 libva info: va_getDriverName() returns 0 libva info: Trying to open /usr/lib64/dri/r600_drv_video.so libva info: Found init function __vaDriverInit_0_40 libva info: va_openDriver() returns 0 vainfo: VA-API version: 0.40 (libva ) vainfo: Driver version: mesa gallium vaapi vainfo: Supported profile and entrypoints VAProfileNone : VAEntrypointVideoProc # end of output and there should be more, right? In dmesg I see: .... [ 2.125588] [drm] initializing kernel modesetting (KAVERI 0x1002:0x130F 0x1849:0x130F 0x00).

Could you tell your AMD APU(s) is still ok and working in respect to UVD(video acceleration) in recentkernels/mesas ? many thanks, L. .
