Transparent Squid and FirewallD : fine-tuning question
by Nicolas Kovacs 19 May '20

19 May '20

Hi, I just setup a very basic HTTP proxy with Squid on a router running CentOS 7. Up until early 2020 I've been using a bone-headed shell script with iptables to configure my firewall. But I decided to follow advice from a few gurus on this list, and I've since moved my configurations to FirewallD, which works nicely. There's one configuration left to tackle, that's port redirection for the Squid proxy server. Which also works fine, though I'd like to figure out a little detail. Here goes. My router has two network interfaces, which I've aptly named WAN and LAN in the NetworkManager configuration: $ nmcli con show NAME UUID TYPE DEVICE WAN 9574b606-8f6d-3edc-95ad-8165df0f3fce ethernet enp2s0 LAN c726b168-1fcd-4dc5-a01d-8ad8a1ba38ee ethernet enp3s1 Squid is acting as a transparent proxy server: $ sudo grep http_port /etc/squid/squid.conf http_port 3128 transparent In my firewall configuration, all requests to port 80 (HTTP) are redirected to port 3128: $ sudo firewall-cmd --permanent --add-forward-port=port=80:proto=tcp:toport=3128:toaddr=192.168.3.1 $ sudo firewall-cmd --reload $ sudo firewall-cmd --list-all internal (active) target: default icmp-block-inversion: no interfaces: enp3s1 sources: services: dhcp dns http squid ssh ports: protocols: masquerade: no forward-ports: port=80:proto=tcp:toport=3128:toaddr=192.168.3.1 source-ports: icmp-blocks: rich rules: In the current state, this configuration works as expected. When a client desktop in the 192.168.3.0/24 network browses HTTP sites on the web, it appears in the Squid log on the server in /var/log/squid/access.log. And here comes the question. How can I redirect all HTTP requests to port 3128 EXCEPT THOSE THAT ARE DIRECTLY AIMED AT THE PROXY SERVER? Here's the thing. The proxy server (amandine.sandbox.lan) is also running httpd to display a static information page for the local network. Now client desktops can access http://amandine.sandbox.lan in a web browser just fine. But this still goes through the proxy, and I'd like these requests to rather be handled directly. In iptables syntax this would vaguely look like this: $ iptables -A PREROUTING -t nat -i 192.168.3.1 -p tcp \ ! -d 192.168.3.1 --dport 80 -j REDIRECT --to-port 3128 How can I translate the "! -d 192.168.3.1" part into some FirewallD-specific syntax ?

Centos8.1 Plymouthd crash 913: ply_event_loop_watch_for_timeout: Assertion `seconds > 0.0' failed.
by LAHAYE Olivier 18 May '20

18 May '20

Hi, I’m running a special initrd generated for SystemImager with a special dracut module that relies on plyouth scripted theme. It works perfectly on CentOS-6, CentOS-7, OpenSUSE-42.3, Fedora-29 (not tested later) and used to work on CentOS-8.0 Since CentOS-8.1 was released, IT chrashes with the following error: Plymouthd crash 913: ply_event_loop_watch_for_timeout: Assertion `seconds > 0.0' failed. I’m running quemu 5.0.0 with tianocore UEFI bios on MacOS (using accel=none or accel=hvf) (Bug also occurs with standard 256k bios) When I strace, I see multiple reasons but I can’t tell wich one is fatal. 1/ plymouthd reads /etc/Plymouth/plymouthd.conf (ok), then tries to read them from /var/run/plymouth/themes/<themename> instead of /usr/share/plymouth/themes/<themename>/ . As it fails it tries to read /var/run/plymouth/plymouthd.defaults (fails) then /usr/share/plymouth//plymouthd.defaults (ok) then it tries to read the theme /var/run/plymouth/themes/<themename>/<themename>.plymouth (fails) but never tries to read in from /usr/share/plymouth/themes/<themename>/<themename.plymouth> ??? It still continues 2/ After a few things, it tries to read /sys/devices/virtual/drm/ttm/uevent (ok) and the it tries to read /run/dev/data/+drm:ttm (fail). Is it expectable or does this means a problem like a missing udev rule or a boch driver bug or something else? 3/ Same as step 2 4/ Crash with @lymouthd: ply-event-loop.c:913: ply_event_loop_watch_for_timeout: Assertion `seconds > 0.0' failed. I’ve reported this in Centos-8.1 with no return and then RedHat-8.1 today. RedHat 8.1 bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1836828 CentOS-8.1 bug report: https://bugs.centos.org/view.php?id=17140 Any idea where I could look for? More likely a plymouth bug or an udev missing rule or something else? (full dmesg and strace log in bug reports) Thanks a lot for any tips. PS: looking at google results, the only things I can find are very old bugs without resolution (not fixed and obsoleted due to new OS release) -- Olivier LAHAYE

CentOS 7 - xfs shrink & expand
by Frank M. Ramaekers Jr. 16 May '20

16 May '20

I'm having some difficulty finding a method to shrink my /home to expand my /. They both correspond to LVMs. It is my understanding that one cannot shrink a xfs filesystem. One must back it up (xfsdump), remove (lvremove) redefine it and then restore it back (xfsrestore). Okay, I'm running into a problem where /home needs to be "unused". If tried going in to "maintance mode", but I ran into a problem with the mount command (after issuing a 'chroot /sysroot'). I then tried using SystemRescueCD to boot to, but it wouldn't mount my 32TB RAID USB drive (something about too big). Any thoughts or suggestions? -Frank

Create Virtualbox image from running system?
by Frank Cox 16 May '20

16 May '20

I see that Microsoft has a utility that (apparently) can read a running system and create an image that can then be imported and run on Virtualbox. https://docs.microsoft.com/en-us/sysinternals/downloads/disk2vhd "You can even have Disk2vhd create the VHDs on local volumes, even ones being converted (though performance is better when the VHD is on a disk different than ones being converted)." Is there anything that does the same thing for Linux, and can image a system like that while it's actually running? -- Can we uninstall 2020 and install it again? This one has a virus.

Ailing MATE desktop
by Robert G (Doc) Savage 16 May '20

16 May '20

I need some C8 troubleshooting help with MATE. I'm building a ZFS storage server with a SuperMicro H11SSL motherboard, EPYC 7232 CPU, and 32 GB ECC SDRAM. I installed CentOS 8.1.1911 from the iso as soon as it was released. I'm using the on-board ASPEED VGA video. I installed MATE v1.22 from https://copr.fedorainfracloud.org/coprs/stenstorp/MATE/. The following packages are installed: libmateweather-data-1.24.0-2.el8.noarch libmatemixer-1.24.0-1.el8.x86_64 mate-desktop-libs-1.24.0-3.el8.x86_64 mate-terminal-1.24.0-2.el8.x86_64 mate-themes-3.22.21-1.el8.noarch mate-panel-libs-1.22.2-1.el8.x86_64 mate-desktop-1.24.0-3.el8.x86_64 mate-settings-daemon-1.22.1-2.el8.x86_64 mate-polkit-1.24.0-2.el8.x86_64 mate-notification-daemon-1.22.1-1.el8.x86_64 mate-media-1.24.0-2.el8.x86_64 mate-power-manager-1.22.2-1.el8.x86_64 mate-system-log-1.22.2-2.el8.x86_64 libmateweather-1.24.0-2.el8.x86_64 libmatekbd-1.24.0-1.el8.x86_64 mate-utils-common-1.22.2-2.el8.noarch mate-disk-usage-analyzer-1.22.2-2.el8.x86_64 mate-user-guide-1.24.0-1.el8.noarch mate-menus-preferences-category-menu-1.24.0-2.el8.x86_64 mate-dictionary-1.22.2-2.el8.x86_64 mate-menus-1.24.0-2.el8.x86_64 mate-session-manager-1.24.0-1.el8.x86_64 mate-backgrounds-1.24.0-1.el8.noarch mate-search-tool-1.22.2-2.el8.x86_64 mate-panel-1.22.2-1.el8.x86_64 mate-system-monitor-1.24.0-1.el8.x86_64 mate-applets-1.24.0-2.el8.x86_64 mate-control-center-1.22.2-2.el8.x86_64 mate-icon-theme-1.24.0-1.el8.noarch mate-control-center-filesystem-1.22.2-2.el8.x86_64 mate-menus-libs-1.24.0-2.el8.x86_64 mate-user-admin-1.5.1-3.el8.x86_64 mate-calc-1.24.0-2.el8.x86_64 mate-screenshot-1.22.2-2.el8.x86_64 mate-screensaver-1.24.0-2.el8.x86_64 About two weeks ago following a reset, after a normal login an incomplete MATE desktop appeared. The background is black. There is no visible mouse, although there is some ghostly pixel movement in the top toolbar when what should be the mouse cursor floats over each of those toolbar icons. I can hit Enter and start whatever app the ghost cursor is over, and the mouse works only within that app's window. I'm a long-time user of MATE ever since GNOME3 was released, but until now I've never had any problems with it. I have no idea where to start troubleshooting. I've looked in journalctl, systemctl, and dmesg, but found nothing obvious. There's nothing in the MATE wiki to help. I'm open to any suggestions where to start looking. --Doc Savage Fairview Heights, IL

Can't move to Centos 8
by david 15 May '20

15 May '20

Folks I've been trying to convert my systems to Centos 8, seeing the EOL on the horizon a few years away. One of my systems is a Mac-Mini, and support for that has been discontinued. I'm wondering what the community suggests among these alternatives: 1) Stay with Centos 7 even after EOL hoping market pressures will add Mac-Mini support 2) Spend a few hundred dollars on a small, **quiet** replacement (ugh) 3) Convert to the Debian/Ubuntu distro. 4) Hope someone figures out a solution. By the way, the same issue exists, I believe, also for other Mac products, such as the newer laptops and servers. David

CentOS 8 Client to Windows file share SSO Active Directory
by DHilsbos＠performair.com 15 May '20

15 May '20

All; My Google foo is failing me, and searching through the last 10 months on this mailing list hasn't helped either. We have an existing Active Directory domain set up, and I'd like to add a CentOS 8 Workstation to it. I have experience using both realmd and manual configuration to allow local login with AD accounts to various Linux distribution, and have this working on my test system. I used realmd this time, and it configured sssd. I have one problem that I've never been able to solve; when I attempt to connect to a remote file server, while logged on to the CentOS 8 system using a domain account, it asks for credentials. Theoretically, this should work as it's just Kerberos. Can anyone point me at resources on what is needed for SSO to domain resources to work properly? This may be related to another issue that I'm seeing; I don't see the CentOS 8 user logon event (event ID 4624) on the Domain Controller. I see lots of logon events for the computer account, but none for the user account. Thank you, Dominic L. Hilsbos, MBA Director - Information Technology Perform Air International Inc.

Default ACL inheritance question
by James Pearson 14 May '20

14 May '20

A bit of a minor off-topic issue, but on the off-chance that someone understands how ACLs work ... I've been trying to see if using default ACLs would help with the following issue: I have a third party application that is running as a non-root user ('user-a') and creating log files with mode 0600 (read/write only to the owner) in a log directory I have another application that runs as another non-root user ('user-b') that needs to read the log files created by 'user-a' I can't change the mode of the log files generated by 'user-a', but I thought I could add a default ACL to the log file's parent directory that gave read access to 'user-b' - i.e. something like: % sudo setfacl -d -m u:user-b:r logdir % getfacl logdir # file: logdir # owner: user-a # group: user-a user::rwx group::r-x other::r-x default:user::rwx default:user:user-b:r-- default:group::rwx default:mask::rwx default:other::r-x Now when new log files are created in logdir, the default ACL is inherited, but 'user-b' still can't read the files - i.e. % getfacl logdir/logfile # file: logdir/logfile # owner: user-a # group: user-a user::rw- user:user-b:r-- #effective:--- group::rwx #effective:--- mask::--- other::--- i.e. the effective access for 'user-b' is '---' - which is no access to read for 'user-b' I'm not sure where 'effective' comes from? If I now explicitly add a read ACL for user-b to logdir/logfile: % sudo setfacl -m u:user-b:r logdir/logfile % getfacl logdir/logfile # file: logdir/logfile # owner: user-a # group: user-a user::rw- user:user-b:r-- group::rwx mask::rwx other::--- and 'user-b' can read logdir/logfile I guess I'm missing something on how default ACLs are meant to work - can anyone explain what is happening here or point me in the right direction ? I've actually 'solved' the issue with a suitable sudoers rule that allows 'user-b' to run the required command as 'user-a', but I would like to find out why this default ACL method doesn't work Thanks James Pearson

CentOS 8 updates
by Bill Maidment 13 May '20

13 May '20

Hi Is it my imagination/impatience, but I don't seem to have received any updates to CentOS 8 recently. I'm thinking particularly of firefox which was updated in CentOS 7 for a critical security update. Is there a backlog of CentOS 8 updates behind the 8.2 release? I noticed on a few occasions that my local mirroring had picked up and later deleted a lot of "tmp" files for CentOS 8, is that an indication that something is on the way? I understand that everyone is struggling with Covid19 restrictions, so just tell me to get back into my isolation if I'm just a bit too impatient. -- Cheers Bill

Jitsi Meet on CentOS 7 ?

Hi, Anyone here managed to run Jitsi Meet on a CentOS 7 server ? As far as I can tell, it's one of the nicer open source videoconferencing solutions out there. I gave it a spin on https://suricate.tv and now I'd like to install it on one of my servers. Unfortunately the Jitsi developers only provide documentation for Debian/Ubuntu. Well, there is some sort of guide for CentOS around. As far as I can tell, the purpose of this guide is to encourage CentOS users to switch to Debian/Ubuntu. :o) Anyway, if you have a pointer to some comprehensible docs, I'd be grateful.

Monitoring network traffic to a host
by Ian Pilcher 13 May '20

13 May '20

Background - I am having an issue with occassional pauses when streaming high-bitrate media across my home network to my smart TV. I *suspect* that the root cause is the (incredibly lame) 100 Mbps Ethernet interface in the TV. In order to confirm that the peak bitrate really does max out the 100 Mbps connection, I'd like to monitor the communication between my NAS and the TV. The two devices are on separate VLANs, with routing performed by a CentOS 7 system, so it should theoretically be relatively simple to use an appropriate utility on the "router" to monitor and, if possible, graph the network traffic going to the TV. Ideally, I could run said utility for the entire time that the media file is playing and then look at its pretty graph to check if/when the bitrate hit 100 Mbps. Being able to watch the pretty graph in real time through a web interface would be nice as well, but is not required. Is any such program included in CentOS 7 or EPEL 7? The closest thing that I've found thus far is iftop (despite its lack of pretty). Unfortunately, it won't allow me to see the peak bitrate over the whole period in which the media is playing. Thanks for any suggestions! -- ======================================================================== In Soviet Russia, Google searches you! ========================================================================

xvidtune powertools CentOS 8
by Jerry Geis 13 May '20

13 May '20

Hi All - I was looking all over for xvidtune on Centos 8. could not find it. tried yum provides "*/xvidtune" tried yum search xvidtune Google pointed me to: https://centos.pkgs.org/8/centos-powertools-x86_64/xorg-x11-apps-7.7-21.el8… So I installed the apps and of course xvidtune is part of that. However just curious why the provides or search did not point me there ? Should it have? Thanks, Jerry

no images from www.imdb.com
by Michael Hennebry 13 May '20

13 May '20

For some reason, I no longer seem to get images from www.imdb.com , i.e. Internet Movie DataBase. The effect is really weird. I get from Firefox, Konqueror and Chromium. I'm running Centos 7. It's been happening for a few months now, so I really cannot tell what changed that mioght have caused it. How do I debug and fix this? Chromium still asks me for passwords a lot. I expect that is a separate issue. -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

CentOS 8 installer bug
by isdtor 11 May '20

11 May '20

CentOS 8.1.1911 has a bug in the installer. It is not possible to use more than one NFS repo via kickstart repo directive as the installer tries to mount all of them on /run/install/.nfs. You get this DBG payload: /run/install/.nfs already has something mounted on it message for all but the first one. The problem was reported for Fedora 29/30. https://bugzilla.redhat.com/show_bug.cgi?id=1669711 Do we know if this is fixed in RHEL 8.2?

DND Issues in Gnome (GTK3 regression)

Does someone uses EL8 as a workstation (GUI) here? This bug is super annoying https://bugzilla.redhat.com/show_bug.cgi?id=1808900 and it seems not to get addressed in the current branch. How could a developer work with a forced delay in the UI (since a year now). Solution maybe in 8.3 ETA end of the year? Seems that all RH employees uses OSX as workstation (my impression of the summit) :-) This bug is located in gtk3 and should also hit non-GNOME users. Am I the only one here? Is CentOS Stream the workplace to address this bug? -- Leon

Zoom....
by mark 11 May '20

11 May '20

Hi, folks, Updated CentOS 7 the other day. Updated zoom last night. Ancient (15 yr old) USB camera, Logitech QuickCam Express. If I run LD_PRELOAD=/usr/lib64/libv4l/v4l2convert.so cheese, I get video. Zoom, with or without the LD_PRELOAD - no video. I've tried stracing zoom, and created a file /etc/ld.so.preload, with the contents of /usr/lib64/libv4l/v4l2convert.so, and in strace, I see it loading it, but still no video. Anyone got any clues?

discord: things to do to run it.

Hi, folks, Installed discord last night, everything, including video worked, but not voice. As usual, I logged out last night before bed, and voice seems to work. Used the tgz, of course. HOWEVER, note that you *do* need to install libatomic for it to work properly, otherwise when it comes up, it says "the installation is corrupt", and the only button there, for help, is *ONLY* for Windows. I found through searching that it did need this. Install that, and no error message. mark

CentOS 8 and xvidtune and Nouveau

I have an old laptop W530 I put CentOS 8 on. I was trying to install xvidtune - seems to not be available ? Thought that was part of X. Also trying to get Nouveau to be a higher resolution than 1024x768. I found the wiki, but adding video= to the kernel command line and regen grub did not do anything. Other documentation there seemed OLD. Anyone know how to correctly get Nouveau in 1920x1080? Thanks, Jerry

CentOS 8 installation
by isdtor 08 May '20

08 May '20

Are there still a lot of rough edges in this area? There are some things I simply can't get to work. This is about kickstart installations. Finding the right stuff for the %packages sections is lucky dip at best. The RHEL manual points to the comps file, really? This file isn't meant to be parsed by humans. Specifying an environment - the example "Infrastructure Server" doesn't exist. Is this one of the areas where CentOS deviates from RHEL? I did find server-product-environment, custom-environment, minimal-environment. I followed the link in the documentation to the kickstart file generator. The generated file isn't usable as is, specifically the %packages section - anaconda says there is no group dns-server, for instance. Which dnf later confirms. The group list in dnf also seems to be a lot shorter than it used to be under 7? Specifying %packages --multilib, this is where it breaks down completely. For the chosen group/package mix, which works perfectly without multilib, anaconda complains about conflicts for files provided by both the i686 and the x86_64 version of, in this case, gdb-headless and sssd-common. Attempting to fix this with -gdb-headless.i686 -sssd-common.i686 fails, these lines are being ignored. Excluding gdb-headless altogether fails also because the main gdb package pulls it in. Honestly, I'm not sure where to go from here.

libQt5Core.so ver 5.12

Hello, For the last few days, 'dnf upgrade' on my Centos 8 installation has been showing problems saying that it cannot install the best update candidates for packages (kf5-*) because nothing provides libQtCore.so.5(Qt_5.12). My system shows that it presently has libQtCore.so.5(Qt_5.11). I've been keeping the system up to date using the --nobest option in dnf. I could download 'libqt5-core-5.12.8-alt3.x86_64.rpm ' from here and install it but I haven't dared to try. Is there an expectation for when version Qt_5.12 will be in the official repos?

Odd permissions
by mark 07 May '20

I've posted a couple times in the last month, that for some reason, since I rebuilt to CentOS 7 from 6 (same home directory, another partition, of course), when I log out, it restarts with me logged in, and only the second time I log out does it actually log me out. Still debugging that. I have logged in as root, and don't have the problem, so I'm assuming that it's something incompatible, or somehow mis-set in ~/.<whatever>. Looking in ~/.cache, I found something weird: ~/.cache/gnome-control-center, which had permissions of d-w-rwxr-T Say *what*? Anyone got a clue as to why? And while I'm looking for clues, does anyone have any thoughts as to where my issue might lie? mark

rpm command option
by Chris Olson 06 May '20

06 May '20

We located an application recommended by one of customers for sharing certain data. It was available for installation using a few different methods. Using yum was also recommended for the installation. The install instructions began with what appeared to be a fairly typical command as indicated below (with the URL slightly altered). sudo rpm --import https://rpm.xxxxx.com/rpmrepo.key To our junior employee assigned to perform the install on a test system, it seemed like a good idea to do some checking on the rpm option --import indicated in those instructions. They did not find the --import in any of the 14 pages of the CentOS 7 man page for rpm. Some Google searches indicated that the --import option does exist. The repo setup and application installation all went well and took only about three minutes. The app is also working as intended. Is there some good reason for --import being left out of the manual page?

Understanding VDO vs ZFS
by david 04 May '20

04 May '20

Folks I'm looking for a solution for backups because ZFS has failed on me too many times. In my environment, I have a large amount of data (around 2tb) that I periodically back up. I keep the last 5 "snapshots". I use rsync so that when I overwrite the oldest backup, most of the data is already there and the backup completes quickly, because only a small number of files have actually changed. Because of this low change rate, I have used ZFS with its deduplication feature to store the data. I started using a Centos-6 installation, and upgraded years ago to Centos7. Centos 8 is on my agenda. However, I've had several data-loss events with ZFS where because of a combination of errors and/or mistakes, the entire store was lost. I've also noticed that ZFS is maintained separately from Centos. At this moment, the Centos 8 update causes ZFS to fail. Looking for an alternate, I'm trying VDO. In the VDO installation, I created a logical volume containing two hard-drives, and defined VDO on top of that logical volume. It appears to be running, yet I find the deduplication numbers don't pass the smell test. I would expect that if the logical volume contains three copies of essentially identical data, I should see deduplication numbers close to 3.00, but instead I'm seeing numbers like 1.15. I compute the compression number as follows: Use df and extract the value for "1k blocks used" from the third column use vdostats --verbose and extract the number titled "1K-blocks used" Divide the first by the second. Can you provide any advice on my use of ZFS or VDO without telling me that I should be doing backups differently? Thanks David

Hi, I am running CentOS Linux release 7.8.2003 (Core) with php72u-fpm-7.2.30-1.el7.ius.x86_64 version. I am facing the below permission denied issue. I also did the below steps #cd /run #chown -Rc nginx.nginx php-fpm changed ownership of ‘php-fpm/php-fpm.pid’ from root:root to nginx:nginx changed ownership of ‘php-fpm’ from root:root to nginx:nginx #systemctl restart php-fpm again changes it from nginx.nginx to root.root user. nginx error logs > 2020/04/30 03:09:28 [crit] 17175#0: *154570 connect() to > unix:/run/php-fpm/www.sock failed (13: *Permission denied*) while > connecting to upstream, client: 49.207.54.161, server: _, request: "GET / > HTTP/1.1", upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: > "35.128.212.112" > 2020/04/30 03:09:28 [error] 17175#0: *154570 open() > "/var/www/drupal/web/50x.html" failed (2: No such file or directory), > client: 49.207.54.161, server: _, request: "GET / HTTP/1.1", upstream: > "fastcgi://unix:/run/php-fpm/www.sock", host: "35.128.212.112" > 2020/04/30 03:09:35 [crit] 17176#0: *154573 connect() to > unix:/run/php-fpm/www.sock failed (13: Permission denied) while connecting > to upstream, client: 49.207.54.161, server: _, request: "GET / HTTP/1.1", > upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: "35.128.212.112" > 2020/04/30 03:09:35 [error] 17176#0: *154573 open() > "/var/www/drupal/web/50x.html" failed (2: No such file or directory), > client: 49.207.54.161, server: _, request: "GET / HTTP/1.1", upstream: > "fastcgi://unix:/run/php-fpm/www.sock", host: "35.128.212.112" > 2020/04/30 03:09:49 [crit] 17175#0: *154575 connect() to > unix:/run/php-fpm/www.sock failed (13: Permission denied) while connecting > to upstream, client: 14.98.153.6, server: _, request: "GET / HTTP/1.1", > upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: "35.128.212.112" > 2020/04/30 03:09:49 [error] 17175#0: *154575 open() > "/var/www/drupal/web/50x.html" failed (2: No such file or directory), > client: 14.98.153.6, server: _, request: "GET / HTTP/1.1", upstream: > "fastcgi://unix:/run/php-fpm/www.sock", host: "35.128.212.112" > 2020/04/30 03:09:50 [crit] 17175#0: *154575 connect() to > unix:/run/php-fpm/www.sock failed (13: Permission denied) while connecting > to upstream, client: 14.98.153.6, server: _, request: "GET / HTTP/1.1", > upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: "35.128.212.112" > 2020/04/30 03:09:50 [error] 17175#0: *154575 open() > "/var/www/drupal/web/50x.html" failed (2: No such file or directory), > client: 14.98.153.6, server: _, request: "GET / HTTP/1.1", upstream: > "fastcgi://unix:/run/php-fpm/www.sock", host: "35.128.212.112" > 2020/04/30 03:10:46 [crit] 17176#0: *154578 connect() to > unix:/run/php-fpm/www.sock failed (13: Permission denied) while connecting > to upstream, client: 184.22.107.148, server: _, request: "GET / HTTP/1.1", > upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: "35.128.212.112" > 2020/04/30 03:10:46 [error] 17176#0: *154578 open() > "/var/www/drupal/web/50x.html" failed (2: No such file or directory), > client: 184.22.107.148, server: _, request: "GET / HTTP/1.1", upstream: > "fastcgi://unix:/run/php-fpm/www.sock", host: "35.128.212.112" Please let me know if you need any additional information.

fcitx and switching between keyboards
by H 02 May '20

02 May '20

This is an old issue for me running CentOS 7, latest update. I am using fcitx to switch between keyboards, two western ones and Chinese pinyin keyboard. Ever since I installed CentOS 7 over two years ago, I have been unable to resolve issues where I can maintain keyboard setting within one application, notably chromium, and/or between applications. fcitx has a setting for allowing the keyboard choice to remain across applications but it does not work - so far. Further, in chromium, even when within an IME, every time I hit ENTER, the keyboard resets back to the default (EN_US). Needless to say, this makes for some very tedious typing using an alternative keyboard. I do not have this problem remaining within a single IME in Thunderbird, nor in Firefox, nor in LibreOffice. I can switch back and forth between one of these apps and the keyboard switches back to what I last used in that app when switching back to the app - /provided I have used Chinese/. It does not work when I use different western keyboards in the various apps. Is anyone using fcitx switching between different keyboards and can confirm the above - or refute it?

dhcpd: Not searching LDAP
by Frank Cox 02 May '20

02 May '20

Whenever my dhcp server is restarted it always puts this entry into /var/log/messages: dhcpd: Not searching LDAP since ldap-server, ldap-port and ldap-base-dn were not specified in the config file This isn't earth-shattering news since I don't have a ldap server and there's no mention of ldap in /etc/dhcp/dhcpd.conf either. So is this an error message? If it's just an informational message then that's one thing, but if it's an error message then what's the problem that it's telling me about and how do I solve it? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com
