概览

Centbot 是一个连接到 freenode IRC 网络的 supybot-limnoria 实例,有助支持 CentOS 的 IRC 社群。

Centbot 能辨认某些「关键字」,触发它回答频道上一些较常出现的提问。

Centbot 运作的方法是监视各个频道并寻找这些关键字,然后在找到时显示相关数据。譬如说你想查看 CentOS-6 的支持结束日期,你可以在频道内发送

@c6eol

然后 centbot 会以结束支持的日期作为答复,及显示距离该日子还有多久。

由于关键字不断增加,关键字的清单一直在改变。你可以私底下查询它来取得现有的清单:

/msg centbot @list alias

你将会在清单的底倍看见 more messages 这些字间;这意味著该 bot 有更多信息要告欣你,并在听候你的吩咐。你可以这样做:

/msg centbot @more

你可以重复地做直至完成显示所有信息。

要是你想查看个别关键字所显示的信息,你可以私底下发送:

/msg centbot @c6eol

新增或更改现有关键字的推荐可发送至以下指令所列出的用户:

/msg centbot @botstaff

为方便用户,以下列表包含了现时所有已知的关键字。此列表是每日自动创建的。

altarch For more information on the AltArch efforts please see https://wiki.centos.org/SpecialInterestGroup/AltArch
amazonlinux #centos is unable to assist with Amazon Linux as it is a completely different distribution. For Amazon Linux support please contact Amazon support. ##aws may be able to assist with some issues as well.
announcements For update notifications you are advised to join the centos-announce mailing list. You can configure which releases and architectures you want updates for via the mailing list config web page. Please see https://wiki.centos.org/GettingHelp/ListInfo for more information on this and other mailing lists.
appstream For information on the Life Cycles and Support policies for AppStream content please see https://access.redhat.com/support/policy/updates/rhel8-app-streams-life-cycle. Note that CentOS follows the upstream support model with the exception we do not provide extended support for EOL releases.
arm The #centos-arm channel exists for people interested in the CentOS ARM platform.
arp ifconfig $*
ask Instead of asking to ask, please just state your problem clearly and concisely. If someone is available to assist you they will.
atomic We strongly advise against the use of the Atomic Rocket Turtle repo, aka atomic or art; it replaces core packages and can, does and will cause stability issues with CentOS systems.
atrpms The atrpms repository is effectively abandoned and should _not_ be used. Use alternative package sources such as epel, nux-dextop, etc. Please see https://wiki.centos.org/AdditionalResources/Repositories for a list of community vetted repositories.
atsign The use of '@' in addressing people on IRC breaks many clients with the result that such clients will not properly highlight their nick when they are being addressed. If you want to ensure you get someones attention you should not use '@'.
audit2allow You can find info about how to create your own policy from the event log in permissive mode on https://wiki.centos.org/HowTos/SELinux#Creating_Custom_SELinux_Policy_Modules_with_audit2allow
away We would greatly appreciate it if you would disable your client's automatic /away functionality while in this namespace. This also includes away nick changes or nick changes indicating status. The nature of IRC makes such status changes irrelevant and just adds to channel noise. Thank you for your understanding.
aws For a list of Amazon AMI ids for CentOS images please see https://www.centos.org/download/aws-images/

backports Please see https://access.redhat.com/security/updates/backporting/ for information on backporting of security fixes and features in CentOS and RHEL. Additionally https://access.redhat.com/solutions/2074 may also be of use.
badadvice Bad advice is bad. It is a disservice to the user and it is an additional support burden for someone to have to clean up after you. Please think about the advice you give and ensure that it is correct before you set someone on the wrong path.
banned If you find yourself banned on any of the #centos channels please see https://wiki.centos.org/irc/banned
beta As a general rule the CentOS Project does not issue beta or RC releases for upcoming releases.
board For a list of the current members of the CentOS Board please see https://www.centos.org/about/governance/#current-sitting-board

centoswebpanel The product known as 'CentOS Web Panel' is not associated with the CentOS Project, nor is it recommended for use by this channel or the CentOS Project. Additionally there is a concern of possible Rights Infringement by the non-authorized use of the CentOS Marks. Users are strongly cautioned against the use of the product.
cherrypicking updates $*
cityfan The 'cityfan' repo is known to be problematic and you are _strongly_ discouraged from using it. See https://wiki.centos.org/AdditionalResources/Repositories for more information.
clearos ClearOS is _not_ CentOS and thus can not be supported in this venue. Please seek assistance from their support venues.
cloud We are aware of the delay in the timely release of the various CentOS cloud images. Unfortunately at this time we do not have an accurate ETA on these images being made available.
cloudlinux If you have installed CloudLinux on your CentOS system then it is no longer CentOS and you need to ask the Cloudlinux folks for future support.
clustering For assistance with linux-based clustering you may find you get better results if you ask in either #linuxcluster or #clusterlabs
contribute More information for those wishing to contribute to the CentOS Project can be found at https://wiki.centos.org/Contribute
cpan Using CPAN on CentOS is a wonderful way to wreck your system. CPAN does not play nicely with the packaging system. Please use EPEL or other trusted repos to install packaged PERL modules. Please see https://wiki.centos.org/AdditionalResources/Repositories for more information on 3rd-party repos.
cpanel We are not able to support either cpanel or the boxes that it is installed upon here due to the many changes that this application makes to the base OS.

digitalocean You can convert a droplet to permit self-managed kernels by following https://www.digitalocean.com/community/tutorials/how-to-update-a-digitalocean-server-s-kernel
directadmin DirectAdmin, like all such products, is not supported in this venue due to the gross changes it makes to the base platform.
disablenm You may remove NetworkManager with yum remove NetworkManager or simply disable it with chkconfig NetworkManager off; chkconfig network on; service NetworkManager stop; service network start. In either case you will need to edit your interface configuration files in /etc/sysconfig/network-scripts/ifcfg-*
docs Except for subscription-manager, Red Hat documentation (https://docs.redhat.com) is applicable for all versions of CentOS. See also errata and installation documentation at https://docs.centos.org . Additional information is also on the CentOS wiki at https://wiki.centos.org

entitlement We are, unfortunately, living in an era of entitlement. Alas, this attitude does not generally go over well in this venue; you are not entitled to support. Support is a privilege, provided by community volunteers on their own time. Expecting support from such volunteers is exceptionally rude and we would greatly appreciate it if you wouldn't do that.
epel EPEL (Extra Packages for Enterprise Linux) is a third party yum repository. You can install EPEL by running 'yum --enablerepo=extras install epel-release' and gain access to several thousand more packages for CentOS/RHEL. Please note that issues with the EPEL repository, packages or mirrors should be reported to #epel. Please note that CentOS has no influence over EPEL.
errata The various announcement types listed on the CentOS-Announce mailing list are as follows: CESA - Security Announcements; CEBA - Bugfix Announcements; CEEA - Enhancement Announcements
esr smartquestions $*
eta The CentOS Project is unable to provide ETAs on pending releases. This is not meant as a means to hinder you in your planning but rather to provide the Project with ample time to produce a quality product. If scheduled releases are important perhaps looking into RHEL would be of benefit to you and your organization.
expectations Please note that this channel is unable to assist you with your expectations as they are not under our control and we have no influence over them. Managing expectations is something that one needs to work at.

greetings As a general rule we tend to frown on 'channel greetings' as it causes IRC clients to show channel activity and makes people stop what they are doing and look in.
grsec If your 'uname -a' output has the strings 'grs' or 'grsec' in the kernel version you are running a grsec-enabled kernel. This is not an official CentOS kernel and thus can not be supported in this channel. You are encouraged to seek assistance from your provider.
grub If you are having problems with grub such as new kernels not being detected you should check the symlink exists between /etc/grub.conf -> ../boot/grub/grub.conf
grub2 If you are having problems with grub2 on CentOS 7, such as new kernels not being detected, you should check the symlink exists between /etc/grub2.cfg -> ../boot/grub2/grub.cfg (legacy BIOS) or /etc/grub2-efi.cfg -> ../boot/efi/EFI/centos/grub.cfg (UEFI systems)

i686 The 32-bit x86 build of CentOS 7 has now been released and you can see the announcement at https://lists.centos.org/pipermail/centos-announce/2015-October/021430.html
ibm The IBM acquisition of Red Hat was finalized July 9th, 2019. More information including supplementary links can be found at https://blog.centos.org/2019/07/ibm-red-hat-and-centos - we ask that discussion regarding this topic, including speculation on the future, be conducted in #centos-social.
ifcfg You can find a list of the parameters used by ifcfg-$interface files in /usr/share/doc/initscripts-*/sysconfig.txt
ifconfig The 'ifconfig', 'netstat', 'arp' and 'route' commands have been deprecated for over a decade now and have been removed from the default CentOS 7 and CentOS 8 installs. You are strongly encouraged to learn to use the 'ip' and 'ss' commands instead. If you really need the old tools they are available via 'yum install net-tools'.
illegal Discussion of activities which violate criminal or civil law, either in the US or internationally, are not welcome in this channel and such discussions must immediately move elsewhere.
iptables If you need assistance with iptables rules we ask that you place the output of 'iptables-save -c' on https://paste.centos.org and then post the resulting url to the channel to best aid you in troubleshooting your problem.
irc Please see https://wiki.centos.org/irc for information about this and other CentOS channels on freenode. Also, please read the topic by typing /topic in your client.
isorebuild Rebuilding the CentOS supplied isos is too complicated a subject for an IRC channel and is thus off topic. You can use the upstream doc on https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/anaconda_customization_guide/sect-iso-images as a starting point but there is no support for that process here.
itsdead CentOS-6 is now End-Of-Life and all support has now ended. There will be no more updates and the repos will soon be moved from the mirrors to vault.centos.org. If your business requirements call for continued use of EL6 you will need to contact Redhat about their ELS offerings for RHEL6.

nosupport For support with CentOS Linux you want to /join #centos and ask there; this is our community social channel and we don't provide support here.
novz This channel is unable to support openvz as either a host or a guest. The kernel is limited in functionality which places undue hardship on users. Please seek assistance from your hosting provider. Alternatively find alternative hosting that uses kvm or similar virtualization technology.
ntfs For help with NTFS on CentOS, please see https://wiki.centos.org/TipsAndTricks/NTFS
ntp Information on setting up NTP can be found at: https://kbase.redhat.com/faq/docs/DOC-2148

otherspins You are not running CentOS! Please read https://wiki.centos.org/AdditionalResources/OtherSpins for more information and ask your provider to give you real CentOS.
othervenues There are other venues available for you to continue this conversation. You can /msg alis list *topic* to find channels with similar interests; move to private messages via /query otherparty; or even create your own channel via /join ##newchannel but at this time we ask you to pick one of those as your conversation is no longer topical to this venue. Thank you.
ovh Support issues with OVH provisioned boxes, using their images, need to be addressed by OVH themselves.
packageupdates The CentOS project endeavors to make package updates available as soon as possible. But there is not, nor can be, any estimations of when any individual update will be released. _Typically_ it is within a few hours of upstream release but this may be delayed for any number of reasons. We ask that you remain patient.
packaging In CentOS the packaging format is known as 'rpm' and the package management system is known as 'yum'; alternate package management systems, while available, are not supported in this venue and are not recommended.
packagingguide For a good writeup on RPM packaging please see https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/rpm_packaging_guide/ and https://rpm-packaging-guide.github.io/
panels Due to the gross changes that panels make to the underlying OS we are unable to support such boxes in this channel as they are effectively no longer running CentOS but rather a mixture of CentOS and the parts that they have replaced. You are encouraged to contact your hosting provider or panel vendor for further assistance.
partnership relationship $*
paste Please do not paste more than 3 lines in the CentOS IRC channels. We ask that you use https://paste.centos.org for anything over three lines. You may 'yum --enablerepo=extras install cpaste' for a command line client. Please note that other pastebins may be ignored by channel users.
pastebin paste $*
pb paste $*
pci You will see many false positive results from PCI scans of CentOS machines as they base their recommendations on banner version numbers and these do not accurately reflect the status of vulnerabilties due to Red Hat's backporting policies. If you're having problems with PCI compliance please refer to @backports, @cve and rpm -q --changelog packagename.
perforce Please note that Perforce (aka Open Logic aka Rogue Wave) are not affiliated with the CentOS Project in any manner and the support they offer has not been vetted by the CentOS Project.
performance There is a known issue with tuned performance profiles under CentOS; tuned defaults to a low-performance profile. For more information and simple directions on how to increase performace please see http://jperrin.org/centos/boosting-centos-server-performance/
pkgsrc The packages that are available from pkgsrc.joyent.com are not supported in this venue. Please seek assistance from joyent.com
plesk Neither Plesk nor the machines it is installed on are supported here due to the large number of changes they make. Please ask for support in ##plesk
pm Many people on freenode dislike being sent private messages without the sender first asking if it is ok to do so. This is a matter of politeness and not meant to offend. freenode even offers user modes to prevent such private messages. Please be respectful and ask before sending.
politics As a means to keep this channel a bit more sane and to help reduce channel temperature we now have a #centos-politics channel for the discussion of current political events.
poll polls $*
polls Polls of the channel are generally pointless. If you have a specific question to ask you are better off just asking it rather than asking the channel 'Does anyone use foo?'
postfix For information on setting up postfix on CentOS, please see https://wiki.centos.org/HowTos/postfix
powertools On CentOS-8 the development libraries, compilers and other development-related tooling is contained in the powertools repo which is disabled by default (dnf config-manager --enable powertools). This is the CentOS equivalent of Red Hat's CodeReadyBuilder repo

shiny No. CentOS isn't shiny. It's not engineered to be all shiny. We don't _want_ it to be all shiny. CentOS is based on Red Hat Enterprise Linux which is all about _stability_ over cutting edge and shiny. If you want shiny you might want to investigate other distros. If you want stable, you're in the right place.
