Re: [CentOS] CentOS 7.3

Hello, I wonder if you could help. I have a requirement to load CentOS 7.3 on to a server. I have the distribution on a bootable USB key. CentOS boots to the first menu but when I select the option to install almost immediately I get the error below: NMI watchdog: BUG: soft lockup - CPU#82 stuck for 23s! [system-udevd:1221] The above error is output every 23s This is a repeatable error condition. When I load CentOS 7.4 on to the server I get no problems. When I load the above CentOS 7.3 distribution on to an older server I get no problems. Has anyone every seen the NMI watchdog error and found a resolution.

Supergrub will boot some .iso files. In the past, I have directly booted a partition I made from a fedora .iso file. Another option *might* be making another .iso file. Mount the file. Copy its filesystem to a directory. Remove some stuff you can live without. Make another .iso file using directions for making a bootable disk. Burn the .iso file to disk. -- 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

Samba config question
by Robert G. (Doc) Savage 16 Mar '21

16 Mar '21

After setting up /etc/samba/smb.conf and running "testparm" in CentOS 7.9.2011, I have noticed that the list of parameters echoed back for the [global] section do not match those in the smb.conf file. Is this normal? [global] in /etc/samba/smb.conf: unix charset = UTF-8 dos charset = CP932 vfs objs = acl_xattr map acl inherit = yes store dos attributes = yes printing = cups printcap = cups load printers = yes # Network related options workgroup = WORKGROUP server string = Samba Server Version %v netbios name = SERVER01 interfaces = lo eth0 192.168.1.0/24 hosts allow = 127. 192.168.1. # Logging options log file = /var/log/samba/log.%m max log size = 50 # Standalone Server Options security = user passdb backend = tdbsam map to guest = Bad User # Name Resolution wins support = yes dns proxy = yes # Printing options load printers = yes cups options = raw # Filesystem options map archive = no map hidden = no map read only = no map system = no store dos attributes = yes When I subsequently run "testparm", I get a shorter and in some cases different list: [global] in "testparm" output: dos charset = CP932 interfaces = lo eth0 192.168.1.0/24 log file = /var/log/samba/log.%m map to guest = Bad User max log size = 50 printcap name = cups security = USER server string = Samba Server Version %v wins support = Yes idmap config * : backend = tdb cups options = raw hosts allow = 127. 192.168.1 map acl inherit = Yes map archive = No vfs objects = acl_xattr Is this normal behavior for Samba?

Re: [CentOS] Bare metal vs. virtualization: Proxmox + Ceph + CentOS?
by Blaž Bogataj 15 Mar '21

15 Mar '21

Hello I'm using ProxMox as virtualization, from verson 2.x. For around 20 servers (most of them are Centos machines) for different services (Zimbra, Apache, MariaDB, PostgreSQL, EDB, ..) and also for MS servers (AD, Exchange, fileserver, MSSql Express, .). They all are running on 5-6 HW servers, different brands and all of them are pretty old. As backup use Synology NAS and nfs with 10gb fc to FC switch. So speed for backup really is not a problem. I slowly moving sata disks to ssd, in same hardware and this is really big advantage in speed. In time of changing disks move virtual machines to other hypervisors. HW Raid5 is really nice with ssd. In 3 years of changing to ssd disks only one fail, but system running and change of disk without downtime ... If I want to test, move, . backup and restore is not an issue. For this year plan is to put one NAS to other location for disaster . ProxMox and software defined storage on 4-5 machines I think for us is the best solution. In point of maintaining there is no problem with upgrading from one release to other - now is version 6.x. Only issue is probably my knowledge how to put this together. All the best Blaz

Restore mails using Thunderbird
by Nicolas Kovacs 15 Mar '21

15 Mar '21

Hi, One of my clients is running CentOS 7 on his workstation. He's using Mozilla Thunderbird with an IMAP account at Infomaniak to manage his mails. Two days ago he shot himself in the foot by playing around with Thunderbird's auto-cleaning features. He enabled "delete all mails older than 60 days" and managed to wipe most of his 13 GB of archived mails. Fortunately his local network has a local backup server (running CentOS 7 and Rsnapshot), which keeps daily snapshots of his workstation. Thunderbird keeps all configuration and mail in ~/.thunderbird, so I simply renamed this to ~/.thunderbird.bak, searched for the latest correct version of ~/.thunderbird three days ago and restored that. Now here's what happens. 1. When starting Thunderbird all the old mail folders and messages appear correctly. So it looks good. 2. After a few minutes most of the messages disappear. Not good. I don't know exactly what's going on here, but it looks like the server is trying to keep the upper hand here by restoring the last (wrong) state of things. Any suggestions ?

remote disk decryption on centos?
by ept8ept8＠secmail.pro 15 Mar '21

15 Mar '21

Hi I was reading about how unlock encrypted root partition from remote (unattended). I'd like asking what is compatible way for this in centos and commonly used by administrators? I think most simple is install dropbear in initramfs for allow remote SSH and manual enter passphrase. I find many HOWTO for that on debian/ubuntu, but nothing for centos. Is there any help, recommend or HOWTO available for centos? Example reference: https://security.stackexchange.com/questions/161974/unattended-disk-encrypt…

Bare metal vs. virtualization: Proxmox + Ceph + CentOS ?
by Nicolas Kovacs 14 Mar '21

14 Mar '21

Hi, Last week I had a disaster which took me a few unnerving days to repair. My main Internet-facing server is a bare-metal installation with CentOS 7. It hosts four dozen web sites (or web applications) based on WordPress, Dolibarr, OwnCloud, GEPI, and quite a number of mail accounts for ten different domains. On sunday afternoon this machine had a hardware failure and proved to be unrecoverable. The good news is, I always have backups of everything. In that case, I have a dedicated backup server (in a different datacenter in a different country). I’m using Rsnapshot for incremental backups, so I had all data: websites, mail accounts, database dumps, configurations, etc. Now here’s the problem: it took me three and a half days of intense work to restore everything and get everything running again. Three and a half days of downtime is quite a stretch. As far as I understand, my mistake was to use a bare-metal installation and not a virtualized solution where I could simply restore a snapshot of a VM. Correct me if I’m wrong. Now I’m doing a lot of thinking and searching. Proxmox and Ceph look quite promising. From what I can tell, the idea is not to use a big server but a cluster of many small servers, and aggregate them like you would do with hard disks in a RAID 10 array for example, only you would do this for the whole system. And then install one or several CentOS 7 VMs on top of this setup. Any advice from the pros before I dive head first into the documentation?

That may not be *generally* possible. You can load-balance your network streams (connections), so that you'll utilize the bandwidth of two physical links in sum, but each individual network stream is going to traverse just one physical link, and will never be faster than whichever link is selected for that stream when it is initiated.

Disk read io very high, but no process perform io read
by yf chu 12 Mar '21

12 Mar '21

We have experienced a very weird problem. The load of the server machine is very high. We use "pidstat" and find that the disk read io is very high. But the processes running on this server do not perform any disk read operation. We also noticed that when we execute "top" command, for most of processes, the values in "SHR" column are zero. Compared with other normal servers, we found that by executing "free -m", the result shows that the buff/cache value in this server is lower than the value of other normal servers. We also found that there were lots of major page faults by executing "ps -o majflt,minflt". Swap is not enabled on this server. What could be the reason for this issue?

R730xd & SD card identfication
by Gregory P. Ennis 10 Mar '21

10 Mar '21

Everyone, We have migrated a platform to a Centos 8 host using kvm guest machines Recently I tried to copy one of the guests to the external SD card on the back of the Dell R730xd, but I have not been able to get the Centos 8 host to recognize the SD card. I can use DRAC interface of the R730xd to see that the SD card is being recognized and the status of the external SD slot is turned from inactive to active when the card is inserted. I have used lsblk, fdisk -l, and 'dmesg | tail' none of which demonstrate that the Centos 8 host is recognizing the SD card. You help would be appreciated. Thanks !! -- Greg Ennis

SHR in top command is zero and major page fault is frequent
by yf chu 08 Mar '21

08 Mar '21

Recently, I found that many processes in our server experienced high frequency of major page faults. The disk IO on this server is also very high. I also noticed that when I execute "top" command, for some processes, the value in SHR column became zero. when I restart these processes, the values of SHR became non-zero again. What could be the reason for frequent major page fault? Is there any connection between zero SHR and major page fault?

I am trying to compile DeltaChat in a CentOS 7 docker container and at one stage have to run: npm install --global electron but the above fails, seemingly because CentOS 7 does not have 'mkdtemp', nor have I found it in a repository. I had previously used: npm install electron --save-dev which installs fine but does not seem to use mkdtemp. yum provides mkdtemp ends up not finding anything but perhaps someone knows this better?

tracking samba changes
by Christopher Wensink 06 Mar '21

06 Mar '21

Good morning everyone. This morning when I came in my boss said that he doesn't have access to the R: drive, which is a samba share to a folder called RP. I looked in /etc/group and his username was not in there. He's had access to this group for years, since before I was at the company. Yesterday I added a new employee to two other groups, saved the change and exited, and I took out an old username out of a few groups but I did not touch my boss's username at all. Is there any kind of trace log that shows changes to a group or to /etc/group that tracks / logs all individual changes that I can trace back to what might have happened that's turned on in the system, to show changes to /etc/group, or does that only get captured through an outside backup?

Tar of files

When I "tar" up an archive the files have an owner bob, when I extract that to another machine bob is there also but user number is different. So when I extract bob is no longer the owner of the files but someone else. Is there a good way to account for this ? User ID on one box being different to the next box ? I was expecting to untar and bob still be the owner . Thanks, Jerry

Thanks to folks on IRC for mentioning that this never made it to the proper announcement channels. Hi folks, CentOS Stream container images are now readily available! podman pull quay.io/centos/centos:stream OR podman pull quay.io/centos/centos:stream8 ## Tags? We expect the 'stream' tag to automatically move forward to new Streams as they come on board. This means when CentOS Stream 9 becomes the Live Stream, quay.io/centos/centos:stream will have 9 based content. The 'stream8' tag can be used while Stream 8 is Live, and during the overlap period between Stream 8 and Stream 9. A 'stream9' tag will be created at the appropriate time to serve the same purpose. You can browse through all of the tags for the CentOS repository here: https://quay.io/repository/centos/centos?tab=tags ## Next Steps - We are still in discussions on how to push these properly to Dockerhub. Since CentOS is an Official Image, there are some extra requirements here that we're working through. If you have questions you can find us on the centos-devel mailing list (centos-devel(a)centos.org) or in #centos-stream on Freenode Cheers! -- Brian Stinson On behalf of the CentOS Stream Team

Tex-Package missing - Best option to proceed.
by Felix Kölzow 03 Mar '21

03 Mar '21

Dear Experts, We are using RHEL8-based distros and CentOS 8 Stream. For specific applications, some Tex-package are absolutely required. It turned out that these packages are not shipped with the available tex-packages in RHEL8 and CentOS8 Stream, e.g. texlive-pgfplots We know that there are some workarounds at this point. Concerning all these options, is there an option that should be considered to be more or less reliable compared to the others? Which procedure would you prefer? Thank you very much for your help. Regards, Felix

Recommendations for webmail client on EL8
by Simon Matter 02 Mar '21

02 Mar '21

Hi all, I'm still trying to find solutions to replace some aging EL6 and EL7 systems. This time I'm looking at email. Postfix and Cyrus-IMAPd are not a problem and also additional things like DKIM are fine. However, I'm wondering what to use to replace good old squirrelmail with. We had a heavily patched squirrelmail with lots of nice things like avelsieve plugin. Since squirrelmail is dead and unable to run on newer PHP, I'd like to use some other tool instead. I was looking at Roundcube but it seems difficult on EL8 because a lot of PHP stuff is missing and not available as RPMs. I guess the same is true for the python things needed for Mailpile. In the end my list only contains Cypht, Rainloop and Afterlogic Webmail lite. Is there anybody running webmail on EL8? Can you make a recommendation on a certain tool? Thanks, Simon

bash: return status of an assignment
by Kenneth Porter 28 Feb '21

28 Feb '21

In the sqm-scripts package for managing network traffic shaping is this line for finding a program suitable for loading the kernel shaping modules: [ -z "$INSMOD" ] && INSMOD=$(which modprobe) || INSMOD=$(which insmod) It seems to set INSMOD to /usr/sbin/insmod, even though /usr/sbin/modprobe is available. (Both are symlinks to ../bin/kmod.) According to this article, the return value of the first assignment should be success and it shouldn't take the fallback statement: <https://unix.stackexchange.com/questions/270828/how-is-the-return-status-of…> Also working the issue here: <https://github.com/tohojo/sqm-scripts/issues/133>

How to install XFCE on CentOS 8?

Hi, Is anyone here running XFCE desktop on CentOS 8? If so, how did you install it? I just tried to install it from EPEL and this is what I got: # dnf group install Xfce Last metadata expiration check: 0:14:01 ago on Thu 11 Feb 2021 10:05:47 CET. No match for group package "NetworkManager-gnome" No match for group package "thunar-archive-plugin" I'm unable to find packages for NetworkManager-gnome or thunar-archive-plugin anywhere in CentOS 8 or EPEL 8. Did I miss something? Thanks, Simon

menu apps like make menu config
by Christopher Wensink 26 Feb '21

26 Feb '21

Good morning everyone, While vi, cat more or less can work (see what I did there..) for looking at every day Linux Administration, sometimes I think it's just easier to work with a menu based interface, where you can select and navigate messages and options, with a little bit of color, possibly function key interaction, and a working interface, similar to using make menuconfig for compiling the kernel and similar to performing a legacy text based install on a new system. Is there a master list of those kinds of apps that have a menu for looking at various things? Can anyone who thinks of more of these apps rattle off some other options such as: abc - for reading logs xyz for text based chat def - for a menu based browser ghi - for a text mail client, etc -- Christopher Wensink IS Administrator Five Star Plastics, Inc 1339 Continental Drive Eau Claire, WI 54701 Office: 715-831-1682 Mobile: 715-563-3112 Fax: 715-831-6075 cwensink(a)five-star-plastics.com www.five-star-plastics.com

OpenStack Training Recommendations
by Paul Heinlein 24 Feb '21

24 Feb '21

Our team at work is looking for OpenStack training options. The training should cover * overview of widely used OpenStack services * network architecture * installation and configuration * ongoing administration, maintenance, and troubleshooting * upgrading We'd prefer workflows based around Puppet or Ansible, since we know those tools, but operational continuity is more important than the tools used. We'd likewise prefer solutions oriented toward CentOS or RHEL, but, again, it's just a preference. We've investigated kolla-ansible for deployment, but we're not adverse to changing toolsets if the upside is right. I'd characterize our team as journeymen to expert system administrators. We specialize in supporting research groups. The training would be to provide skills and knowledge for our team to support OpenStack as a long-term in-house virtualization option. I'd love to hear your first-hand experiences with any specific training offerings. Thanks! (Note: we have other virtualization solutions in place. OpenStack is specifically required by researchers whose wider scientific communities have built workflows for that environment. Suggestions to ditch OpenStack for OtherGreatSolution will be ignored.) -- Paul Heinlein heinlein(a)madboa.com 45°38' N, 122°6' W

18 Feb '21

SO from the man page on date I can do current=`TZ=":America/Indianapolis" date` echo $current current=`TZ=":America/Los_Angeles" date ` echo $current And I get correct data. LA is 3 hours earlier. But doing this: current=`TZ=":America/Indianapolis" date +%s` echo $current current=`TZ=":America/Los_Angeles" date +%s` echo $current I get the same data - its not 3 hours different. What am I not doing correct ? Thanks, Jerry

by H 14 Feb '21

14 Feb '21

I have updated php on a Centos 7 system to use php 7.2 from sclo. Apache running on the system is also using php 7.2 as shown by phpinfo(), however, apache continues to use the default version of php, ie 5.4.16, when that user launches a process from the command line. All other users default to php 7.2 when running from the command line which is correct. For some reason I have missed configuring apache php-cli correctly. I have googled and found many examples on how to change the configuration settings so that apache uses php 7.2 when serving web pages but in this case it is php-cli that needs to be corrected to use a later version. What should I check? What have I missed? By the way, I am not planning to remove php 5.4 from the system since it might be needed for something at a later time. Thanks.

CentOS 7, selinux and pop_port_t
by H 12 Feb '21

12 Feb '21

I am muddling my way through learning selinux when installing a webapp with httpd as the webserver running CentOS 7. The app allows the user to send/receive mail etc but it seems that I have yet to allow access to imap port 993. So far it seems this is configured through pop_port_t but setsebool httpd_can_network_connect 1 does not include pop_port_t. In the audit log I have: type=AVC msg=audit(1613093671.415:155086): avc: denied { name_connect } for pid=22431 comm="httpd" dest=993 scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:object_r:pop_port_t:s0 tclass=tcp_socket permissive=0 Yet, running the below sesearch -A -s httpd_t -c tcp_socket -p name_connect -d -C tells me ET allow httpd_t pop_port_t : tcp_socket name_connect ; [ httpd_can_sendmail ] I am obviously missing something. Does anyone know how to enable access to pop_port_t?

Update - Resizing a QEMU guest display

Strahil Nikolov and I took this conversation off-line for a few days. The thread of our discussion is below. Net result: No solution is yet found.

smba shares are unreachable once or twice per month
by Prengel, Ralf 10 Feb '21

10 Feb '21

Hallo, I ve a problem with my samba-server. We are using a centos 7.7 with an samba exporting samba-shares. Logins are managed by our Windows-AD. The samba server has only the function to exports hares. Windows clients are Win10 patched every month. Our problem: Once or twice a month shares aren't akctive any longer and reachable for the Window-Clients. Network can nor be a reason because the same directory exported via NFS is reachable for all Linux-NFS-Client. Normally we disconect and connect the Samba server in the AD and after a reboot the shares are working again but that cant be the solution ;-) Can anyone give me hints hwo to anaylse and solving the problem. Thanks Ralf

SCLO php70 imap missing
by H 10 Feb '21

10 Feb '21

I am installing php70 on a machine running CentOS 7 for a particular reason and needed sclo-php70-php-imap which I believe is the imap module for php70 from SCL. It, however, does not seem to be available even though https://cbs.centos.org/koji/buildinfo?buildID=24734 suggests it should be. Am I missing something?

Resizing a QEMU guest display
by Bill Gee 09 Feb '21

09 Feb '21

Hello everyone - I think I know the answer, but just in case ... I want to run it by the experts. I have a machines running CentOS 7. "uname -a" returns this: Linux practice7.billgee.local 3.10.0-1160.15.2.el7.x86_64 #1 SMP Wed Feb 3 15:06:38 UTC 2021 x86_64 x86 _64 x86_64 GNU/Linux This machine has an nVidia GS8400 and uses the nouveau driver. Its main job is to be a host for QEMU/KVM virtual machines. The QEMU packages on the host are: [bgee@practice7 ~]$ rpm -qa | grep qemu qemu-kvm-1.5.3-175.el7_9.3.x86_64 qemu-guest-agent-2.12.0-3.el7.x86_64 qemu-kvm-common-1.5.3-175.el7_9.3.x86_64 qemu-img-1.5.3-175.el7_9.3.x86_64 libvirt-daemon-driver-qemu-4.5.0-36.el7_9.3.x86_64 ipxe-roms-qemu-20180825-3.git133f4c.el7.noarch One of the guest VMs is Fedora 33. The guest comes up with a display resolution of 1024x768. I have not found a way to change it to something higher. If I go to the Settings - Display item in Fedora, there is a long list of resolutions. No matter what I choose, the system will switch to that resolution for about 1/2 second and then go back to 1024x768. This happens when using VNC to connect remotely and also when running on the host computer. Resizing the guest display window does nothing except make big black borders around the guest display. The guest video configuration in the virtual machine manager is set for "QXL". In my searching I found several suggestions to use "virtio" instead. When I make that change and start the guest, it immediately throws an error: "This QEMU does not support 'virtio' video device" I also tried "vmvga" and "cirrus". The cirrus setting does not resize and also loses coordination of the mouse pointer. The vmvga setting gives the same message about not being supported in this QEMU. I verified that the spice-vdagent package is installed on the guest VM. The virtual machine manager has "Resize guest with window" set to ON. Just to make life really interesting... Another guest VM on the same host is running CentOS7. That machine happily resizes! It is set for QXL in the virtual machine manager. I think I am just out of luck. I found some references which say that CentOS 7 does not have support for virtio displays. Is that right? Is there some way to resize the Fedora guest? I don't care about dynamic sizing by dragging a window border. If I can choose something and have it stick, I would be happy. Thanks! -- Bill Gee
