Re: [CentOS] Security Updates not properly flagged
Hi, freely does not imply free to redistribute. Of course these informations are available from various sources which allow redistribution, but it takes time to aggregate them - time that someone need to spend doing the necessary research. best regards, Markus On Mon, 2021-06-21 at 13:53 +0200, Gionatan Danti wrote: > Il 2021-06-21 13:34 Pete Biggs ha scritto: > > CentOS does not provide the metadata to allow the --security flag > > to > > work. > > Right. > > > It doesn't provide it because that information from Redhat is > > proprietary and not open source. > > This is not my understanding.

Re: [CentOS] https://blog.centos.org/2020/12/future-is-centos-stream/
Hi, this is really bad news. Back in 2014 [1], sadly no one at RH seems to remember... "Some of the things that are not changing: - - The CentOS Linux platform isn't changing. The process and methods built up around the platform however are going to become more open, more inclusive and transparent. - - The sponsor driven content network that has been central to the success of the CentOS efforts over the years stays intact. - - The bugs, issues, and incident handling process stays as it has been with more opportunities for community members to get involved at various stages of the process. - - The Red Hat Enterprise Linux to CentOS firewall will also remain. Members and contributors to the CentOS efforts are still isolated from the RHEL Groups inside Red Hat, with the only interface being srpm / source path tracking, no sooner than is considered released. In summary: we retain an upstream. Feel free to reach out if you have specific concerns about how this change impacts your CentOS story. URLs mentioned at the bottom of this email should be a good starting point." Crossing fingers that alternatives emerge soon.

Re: [CentOS] systemd syslog.target
Hi, if I get it correctly [1] it is not recommended to use After=syslog but it's not forbidden. But as the syslog.service should not be enabled it is not running anyway. As the man page states: "If a unit foo.service contains a setting Before=bar.service and both units are being started, bar.service's start-up is delayed until foo.service is started up. Note that this setting is independent of and orthogonal to the requirement dependencies as configured by Requires=" [2] it should have no effect including this after even if it's not necessary. I Would recommend not including the After as it's somehow deprecated since systemd v38 (January 2012!). The only effect you may observe is that if syslog.service is started through socket activation your service might be delayed starting up resulting in an non-optimal startup time. However, this might take some ms barely anyone would notice that. best regards Markus [1] https://www.freedesktop.org/wiki/Software/systemd/syslog/ [2] https://www.freedesktop.org/software/systemd/man/systemd.unit.html On Tue, 2020-08-11 at 09:15 +0100, ctcard wrote: > > Thanks Simon,I think my question got a bit lost amongst all the grub > issues - does anyone else have information about whether any > references to syslog.target in systemd unit files can be > removed?ChrisSent from Samsung Mobile on O2 > > Original message > From: Simon Matter via CentOS > Date: 31/07/2020 10:02 (GMT+00:00) > To: CentOS mailing list > Subject: Re: [CentOS] systemd syslog.target > > Hi,>> I've noticed that there are several systemd unit files in > CentOS 7 and 8> with the optionAfter=syslog.targetin the [Unit] > section, but since systemd> version 198 syslog.target has not > existed.I deduce from this that> "After=syslog.target" is ignored by > systemd and can therefore be removed.> Is this correct?

Re: [CentOS] About license at redistribution
Hi, at first I'm not part of the CentOS Project nor I'm a lawyer. But may I can answer your questions. According to the CentOS About page "CentOS Linux is no-cost and free to redistribute." [1]. So as you are planning to redistribute it should be fine to do. While redistributing you also need to consider the legal section [2]. However as you are planning a business you should involve a lawyer to make it clear to you in your special legal situation! To your second question: Yes you definitely should do that, as you make profit from the great work the maintainers do and can't make profit if they discontinue doing this great work. But no one can force you to, it's up to you to take what the community provides without giving anything back.

Re: [CentOS] XRDP idle disconnect
Hi, there is an option in sesman.ini called KillDisconnected. This could be what you are looking for [1]. There is also an option called DisconnectTimeLimit to set your custom timeout [2]. But I haven't tested this method. A more graceful method should be letting your desktop environment terminate idle sessions. Once the desktop session is terminated sesman will notice and clean up what ever it still keeps. For GNOME you may take a look at [3]. But! be aware of data loss due to unsaved data in any programms in the sessions and all the other ugly things that probably happen on an ungraceful session/application termination and the amount of support requests you might get. best regards, Markus [1] ;; KillDisconnected - kill disconnected sessions ; Type: boolean ; Default: false ; if 1, true, or yes, kill session after 60 seconds KillDisconnected=false [2] ;; DisconnectedTimeLimit - when to kill idle sessions ; Type: integer ; Default: 0 ; if not zero, the seconds before a disconnected session is killed ; min 60 seconds DisconnectedTimeLimit=0 [3] https://people.gnome.org/~pmkovar/system-admin-guide/automatic-logout.html On Fri, 2019-09-27 at 16:47 +0300, Todor Petkov wrote: > Hello, > > I have a machine with Centos7, Plasma desktop and XRDP.

Re: [CentOS] looking for a tool to convert my running system into a installation dvd
Hi, probably you are looking for Anacondas kickstart feature. A kickstart installation can be used to install all your packages and provide basic system configuration. It is possible, but not meant to be used as, to even configure the system as you have it currently running using post-install scripts. [1] seems to be a quite good resource to get started with kickstart installations. This is meant to be used if you plan a roll-out on multiple (many) machines where an manual installation is not applicable (in this case some kind of configuration management should be used to keep track of the configurations deployed). If you just want a single (or just some few) system(s) as hole clone of your system (including full configuration), backup and restore seems better. best regards Markus Lange [1] https://people.centos.org/jperrin/Kickstart2.html On Mon, 2019-02-04 at 17:44 +0100, Ralf Prengel wrote: > Hallo, > I m looking for a tool to convert my running system into a > installation dvd. > Thanks for hint. > I found some tools working more or less for debian. > > Thank for hints > Ralf > > Von meinem iPad gesendet > ___ > CentOS mailing list > CentOS@centos.org > https://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Hi Patrick, you can install your lab printers using the lp* / cups* commands in your ks file or using scripts, see centos / redhat / arch / cups docu for more informations on that (arch wiki got some examples).

Re: [CentOS] [Marketing Mail] Re: Cups freeze when remote server is unavailable
Hi, John tries to tell you: Revert your configuration changes to the config file and use the local web interface / lp* / GUI Print Server Configuration tool to setup all printers at work and / or at home using these tools. This method needs a local cups instance that works if your OS is running (if a printer is not reachable for printing cups can still keep the job in it's queue until the printer is reachable). You can find an linux.com article on Printer Setups in [1] (mainly selected for its screenshots of cups web interface and not for its actuality) which should give you all information's to get it work. At least for desktop setups cups should be running by default, see "systemctl status cups" to check if it's running. For a more in-depth view on cups I can recommend reading the archwiki [2]. best regards Markus [1] https://www.linux.com/learn/linux-101-printing [2] https://wiki.archlinux.org/index.php/CUPS On Mon, 2018-10-29 at 15:35 +0100, Patrick Bégou wrote: > Hi John > > thanks for your quick reply.

However, while the versions does not differ that much (an official upgrade path exists, or no layout change was made between the versions) the files work just as if you updated the database using yum (check out spec file from source pkg to find out what happens on package upgrades, you may need to do upgrade steps manually). This should only be a problem when you try to restore to a new major version of postgres. But in that case I would recommend an additional pg_dump backup to have a save fallback. best regards ps: I do not use postgres, please understand my testimony as not tested practically. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] [Marketing Mail] Re: [External] Re: [Marketing Mail] Create CentOS 6 system as "clone" of another - with LVM and different disk sizes
Hi,
I could be wrong, but afaik clonezilla makes bit-accurate copies of the file
system like dd does. Therefore, no configurations should be adapted. Usually
Linux doesn't care where it runs, as long as the underlying 'hardware' (or
virtual hardware) architecture matches.
However, there are a number of configuration files that need to be modified for
such clones, including network settings (local or on your dhcp server),
{crypt,fs}tab (if no bit-accurate copy of the filesystem was used),
/etc/host{s,name} depending on your network setup.
best regards,

Re: [CentOS] [Marketing Mail] Create CentOS 6 system as "clone" of another - with LVM and different disk sizes
Hi,
You can simply boot a live system to create your partition layout and copy it
over the existing system with rsync. Once your system is copied, you will need
to customize all hardware-dependent configuration files such as {crypt,fs}tab,
network configurations, bootloader and so on depending on your setup.
Don't forget to install the bootloader afterwards!
You can also install a minimal system and use a live system to copy the files
from the existing server to the new one (e.g. with rsync -a). This way you do
not have to create the partition layout and bootloader manually.
Using clonezilla would only replace the part of copying the files and installing
the bootloader, all other settings still have to be made. Rsync should be much
faster for data transfer.
Best regards,
- Markus
