Security bulletins for CentOS 8 and CentOS Stream
by Salman Baset 14 Jan '21

14 Jan '21

Hello, I was wondering if security bulletins for CentOS 8 (till its EOL date at the end of 2021) and CentOS Stream will be available any time soon. I have not seen any security bulletins for these two operating systems on this page, but we have seen Red Hat security bulletins for Red Hat 8. https://lists.centos.org/pipermail/centos-announce/ Thanks Salman

LTS
by Thomas Stephen Lee 12 Jan '21

Hi, CentOS Linux can continue as Fedora LTS or something similar with a five-year life cycle. After five years, users can opt for paid upgrades. We can also work with System manufacturers to pre-install the free LTS on their products, which will increase our user base. --- Lee, Community User.

Reboot/shutdown without login
by Kenneth Porter 11 Jan '21

11 Jan '21

I installed CentOS 8 on a Dell server and it's been running fine as a headless system, admin'd remotely by ssh. Now I'd like to allow someone to shut it down at the console without logging in. Is there a way to do that? Or do I need to get the GUI working? I tried switching it into graphical mode ("systemctl isolate graphical") and the console freezes with nothing but a non-blinking text cursor at top left. The usual virtual console switching hotkeys (ctrl-alt F1-F7) don't do anything when it's hung like this. The system is still responsive in my ssh session. It doesn't recover if I switch back to multi-user target so I have to reboot it to make the console useful again. I'm guessing I'm lacking a good video driver. (It's an R720xd I inherited and the latest drivers on Dell's site are for RHEL 7.)

rare but repeating system crash in C7
by Fred 07 Jan '21

07 Jan '21

Hi all, I'm hoping someone can help me figure this out. every now and then (less than monthly, maybe every 2-4 months, or so, I'll walk up to my C7 box (my home PC) in the morning, wiggle the mouse to wake up the screen, and after a second or so, instead of a live screen, the keyboard shift-lock and scroll-lock keys light up. if I wait a few (tens of) second(s) I find it is rebooting, as the BIOS splash screen appears. it boots normally and comes up with everything apparently working fine. Note that I tend to leave myself logged in 24/7/365 since there's nobody here except my wife and myself, and she has her own Linux box. as it happened again this morning, I grabbed some lines from /var/log/messages that show the last few minutes before it rebooted and the first 3 or four statements as it began to reboot: Jan 2 08:50:12 fcshome kernel: xhci_hcd 0000:03:00.0: Looking for event-dma 00000000a9f2cb10 trb-start 00000000a9f2cb20 trb-end 00000000a9f2cb20 seg-start 00000000a9f2c000 seg-end 00000000a9f2cff0 Jan 2 08:50:13 fcshome kernel: xhci_hcd 0000:03:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 8 comp_code 13 Jan 2 08:50:13 fcshome kernel: xhci_hcd 0000:03:00.0: Looking for event-dma 00000000164858d0 trb-start 00000000164858e0 trb-end 00000000164858e0 seg-start 0000000016485000 seg-end 0000000016485ff0 Jan 2 08:51:12 fcshome dbus[1192]: [system] Activating service name='org.fedoraproject.Setroubleshootd' (using servicehelper) Jan 2 08:51:13 fcshome dbus[1192]: [system] Successfully activated service 'org.fedoraproject.Setroubleshootd' Jan 2 08:51:14 fcshome setroubleshoot: SELinux is preventing /usr/sbin/smbd from read access on the sock_file cups.sock.

I note that there was a selinux event early in this list of events, but I see those frequently and they normally don't cause a crash. if I scroll upward from this list, I find more of the same above what is shown here. The selinux event seems to be related to a SMB mount. since I have a Synology box on the LAN, and it stays mounted nearly all the time, I suspect the selinux event has something to do with that, but I have no idea why it would cause a crash once every few months. Is that selinux event something I need to fix? I'm further guessing that "xhci_hcd" has something to do with USB, am I right? If so I don't know what it would be... Clues would be greatly appreciated! Thanks in advance! Fred

Running script before reboot or shutdown
by Carlos Lopez 06 Jan '21

06 Jan '21

Hi all, I am trying to configure a script as a systemd service to run first when a shutdown or reboot is called. This script execute some scp commands to copy some files to other machines. My actual defined systemd’s file is: [Unit] Description=Remote copy some files before reboot/shutdown Before=poweroff.target halt.target shutdown.target reboot.target DefaultDependencies=no [Service] Type=simple ExecStart=/bin/true ExecStop=/usr/local/bin/remote_copy RemainAfterExit=yes [Install] WantedBy=multi-user.target But it doesn’t work. “remote_copy” is working when it is executed from root shell. I am using CentOS-8 fully patched release. Any idea what am I doing wrong? Regards, C. L. Martinez

fail2ban problems - not banning
by Gary Stainburn 06 Jan '21

06 Jan '21

Hi everyone, I've got fail2ban and firewalld set up on a C7 box, in theory protecting dovecot, exim and ssh but I'm not convinced it's doing anything. in /var/log/fail2ban.log I'm getting loads of entries such as: 2020-12-22 19:08:08,100 fail2ban.actions [1836]: WARNING [dovecot] 78.128.113.67 already banned I think this is because the actual ban is not working. I have entries such as: 2020-12-22 19:38:27,619 fail2ban.utils [1836]: ERROR 7f119e95f7f0 -- exec: ports="0:65535"; for p in $(echo $ports | tr ", " " "); do firewall-cmd --add-rich-rule="rule family='ipv4' source address='113.110.47.81' port port='$p' protocol='tcp' reject type='icmp-port-unreachable'"; done 2020-12-22 19:38:27,619 fail2ban.utils [1836]: ERROR 7f119e95f7f0 -- stderr: 'Error: INVALID_PORT: 0:65535' 2020-12-22 19:38:27,619 fail2ban.utils [1836]: ERROR 7f119e95f7f0 -- returned 102 2020-12-22 19:38:27,620 fail2ban.actions [1836]: ERROR Failed to execute ban jail 'dovecot' action 'firewallcmd-rich-rules' info 'ActionInfo({'ip': '113.110.47.81', 'fid': <function <lambda> at 0x7f119f084050>, 'family': 'inet4', 'raw-ticket': <function <lambda> at 0x7f119f0845f0>})': Error banning 113.110.47.81 I've done some Googling and received lots of responses about fail2ban failures but I can't find anything relating to this. Anyone got any ideas?

dovecot option PROFILE=SYSTEM
by david 06 Jan '21

06 Jan '21

Folks In examining the file /etc/dovecot/conf.d/10-ssl.conf I see the text line: ssl_cipher_list = PROFILE=SYSTEM Yet, I cannot find any documentation that explains what that causes, where the values are stored. I ask because I don't see that text line in other installations of Dovecot 2.3 on other distros. Can anyone point me to an explanation? David
