概覽

Centbot 是一個連接到 freenode IRC 網絡的 supybot-limnoria 實例,有助支援 CentOS 的 IRC 社群。

Centbot 能辨認某些「關鍵字」,觸發它回答頻道上一些較常出現的提問。

Centbot 運作的方法是監視各個頻道並搜尋這些關鍵字,然後在找到時顯示相關資料。譬如說你想查看 CentOS-6 的支援結束日期,你可以在頻道內發送

@c6eol 

然後 centbot 會以結束支援的日期作為答覆,及顯示距離該日子還有多久。

由於關鍵字不斷增加,關鍵字的清單一直在改變。你可以私底下查詢它來取得現有的清單:

/msg centbot @list alias 

你將會在清單的底倍看見 more messages 這些字間;這意味著該 bot 有更多資訊要告訢你,並在聽候你的吩咐。你可以這樣做:

/msg centbot @more 

你可以重覆地做直至完成顯示所有資訊。

要是你想查看個別關鍵字所顯示的資訊,你可以私底下發送:

/msg centbot @c6eol 

新增或更改現有關鍵字的建議可發送至以下指令所列出的用戶:

/msg centbot @botstaff 

為方便用戶,以下列表包含了現時所有已知的關鍵字。

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.

cloudlinux

f 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

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 http://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. Please ask in the semi-official #cpanel channel here on Freenode (/join #cpanel) or you may alternatively open a free ticket up via http://tickets.cpanel.net/submit

cr

For information on the Continuous Release repository please see http://wiki.centos.org/AdditionalResources/Repositories/CR

crossposting

We would appreciate it if you would not cross-post questions to multiple channels. Many of us are on the other channels you're posting to and it's annoying and you will find many will be less than helpful as a result.

The ELRepo Project is recommended for additional hardware support beyond that provided by the distribution. Please see http://elrepo.org/tiki/tiki-index.php for more information. They also have the #elrepo IRC channel here on freenode.

enter

Please do not use your Enter key as punctuation. This is a full-text medium where full sentences expressing the whole of your thoughts will help people assist you faster.

enterkey

$1: Hi. Your Enter key appears to be broken as it looks to be randomly pressing itself. A good way to fix this is to type complete sentences and not treat IRC as twitter. It greatly helps to get your point across without annoying people.

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.

multichannel

Asking questions in multiple places is bad because people in the other channel(s) won't see what you've been told here and vice versa. It wastes their time and ours. You're essentially communicating that you think your time is more valuable than the time of those trying to help you.

multimedia

For multimedia desktop support on CentOS-6 and CentOS-7 it is recommended that you look at the nux-dextop repo. It is maintained by a known community member and is trusted. Please see http://wiki.centos.org/AdditionalResources/Repositories for links to that repo.

openssh

Fixes for CVE-2016-3115 and CVE-2015-5600 for openssh are available via yum update on CentOS 6 and 7. The fix for CentOS 5 is to disable X11Forwarding

openssl

OpenSSL-1.0.2 is tentatively planned for EL7.4. It's not yet available. It won't be available until CentOS-7.4 is released at the earliest. Please do not ask as we don't know more than this. See https://bugzilla.redhat.com/show_bug.cgi?id=1276310 for more information.

openvz

OpenVZ kernels (any kernel that returns 'stab' as part of the kernel version via uname -a) do not have access to hardware resources, including loadable modules needed for some firewall options, selinux, TUN/tAP support, ability to modify server time among other functions. You need to contact your provider for more assistance.

ops

There is no automated 'ops' trigger in the CentOS channels. For assistance with IRC administrative issues please check the channel acl and contact an op as necessary.

otherspins

You are not running CentOS! Please read http://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.

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.

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 Redhat's backporting policies. If you're having problems with PCI compliance please refer to @backports, @cve and rpm -q --changelog packagename.

php53

PHP 5.3 is available in the CentOS 5 tree as the php53 package. If you wish to upgrade from the php 5.1.6 packages, you will need to remove them first as they conflict with the newer php53 packages. This is by design.

php7

The IUS project has php70u packages available. See https://ius.io or #iuscommunity for more information.

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.

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?'

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.

sigill

Illegal instruction errors on CentOS 6.8 are a known issue and seem to be with xen guests. There were packages released 2016/07/12 that should fix this problem - use NSS_DISABLE_HW_AES=1 yum update nss-softokn\\* to get a version >= 3.14.3-23.3.el6_8 for the fix

The #centos-social channel is available for general chit-chat and topics that are not directly related to CentOS or which are off-topic in #centos. We appreciate your assistance in keeping the main #centos channel as topical as possible.

sourcebuilds

This venue is unable to provide assistance with building from source or with such software that has been installed from source. You are strongly encouraged to learn how to create proper packages that can be installed via rpm/yum.

sources

You can find the source rpms for CentOS at http://vault.centos.org. Additionally you may read http://wiki.centos.org/Sources to learn about the git repository setup at http://git.centos.org and how to best make use of it.

spdy

There is a known issue with the current mod_spdy module for httpd. It is linked against a vulnerable openssl-1.0.1c and if you have it in use on your server you are still vulnerable to CVE-2014-0160. Please disable the module and restart httpd until they can release an update of their own.

spoonfeeding

Please take a look at http://wiki.centos.org/SpoonFeed for our views on spoonfeeding.

squid

https://bugzilla.redhat.com/show_bug.cgi?id=1202858 is NOT applicable to CentOS. If you'll notice the Version is marked as 6.7 - there is no CentOS-6.7, nor is there a public release of RHEL-6.7. It's BETA.

stackclash

New kernels for CentOS 6 (2.6.32-696.3.2.el6) and CentOS 7 (3.10.0-514.21.2.el7) have been built and published. You'll want to update glibc too so just yum update

stopit

There is, in the general case, no reason to disable integral security layers such as selinux or the host-based firewall. Both services are installed and enabled by default for good reason. Spending the time necessary in learning how to properly manage these security layers is in your best interests.

sudo

In order to ensure sanity of the configuration you are _strongly_ advised to only edit /etc/sudoers by using the visudo" utility. man visudo for more information.

su

There are several ways to become root on a Linux system. See http://wiki.centos.org/TipsAndTricks/BecomingRoot for more information

support

If you require an SLA or a service contract you are strongly encouraged to make use of the commercial offerings from Red Hat. There is no official support for CentOS, only that which the community chooses to provide on a strictly volunteer basis.

systemd2

There is also https://fedoramagazine.org/what-is-an-init-system/ as a general systemd overview.

systemd

For systemd documentation please see http://0pointer.de/blog/projects/systemd-for-admins-1.html . A SysVInit to systemd crib sheet is at http://fedoraproject.org/wiki/SysVinit_to_Systemd_Cheatsheet and other info on http://linoxide.com/linux-command/linux-systemd-commands/ Additionally https://access.redhat.com/articles/systemd-cheat-sheet may be of use as well.

toast

After much deliberation it is our expert opinion that your server is now a heap of useless metal and silicon and should be re-installed.

tutorial

An excellent guide for users that are new to Linux can be found at http://rute.gerdesas.com - while this is not official project documentation it is a well-regarded general introduction to Linux and may be of help. For an introduction to the bash shell take a look at http://linuxcommand.org/lc3_learning_the_shell.php

uname

Please paste the single line of output from the 'uname -a' command run on the machine in question to the channel. We request this information to better assist you. If you are worried about your privacy or security we ask that you _only_ obfuscate the hostname and leave all other information intact.

updates

Please be aware that when updating you must install _all_ updates. Cherry picking updates can lead to corner-case and difficult to diagnose issues and is not supported.

upgrade

There is no method to upgrade from CentOS-6 to CentOS-7 as the tool is currently broken and will almost certainly kill your system. There is no ETA on a fixed version being made available. Please see http://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool for more information. Please understand that this tool is currently BROKEN.

usbinstall

Information on USB key based installs can be found at http://wiki.centos.org/HowTos/InstallFromUSBkey

uselesscat

uselesspipe $\*

uselesspipe

You have been charged one community demerit point for the extraneous and useless use of 'cat' in a pipeline. You have made DMR cry.

vampire

A support vampire is one that considers himself or herself entitled to support, often at the expense of others. A support vampire is a selfish person that does not care to understand that support is granted on a purely volunteer basis and no one is _entitled_ to such.

vault

If you REALLY need an old version of CentOS that is no longer available on the mirrors, then they are available at http://vault.centos.org

versions

To determine what versions of packages are available please browse a nearby mirror. For a list of mirrors please see http://www.centos.org/download/mirrors/

volunteers

vps

You are not running CentOS. Please read http://wiki.centos.org/AdditionalResources/OtherSpins and please ask your provider for further assistance.

vzhostnode

Any and all support issues with boxes that are running, or have been running, the openvz kernels (also known as the VZ host node) are unsupportable in this venue. Please contact your hosting provider for more assistance or contact OpenVZ support directly.

webgateway

The freenode web gateway is banned in #centos due to rampant abuse. Either install a real client or use irccloud if, for whatever reason, you can't install a real client. In either case you will need a registered nick to join the channel as well.

webmin

The webmin, usermin and virtualmin web management interfaces are not supported in this venue. Please seek assistance from their channels (#webmin / #virtualmin) or other support venues.

wget

A workaround for the wget symlink issue referenced in CVE-2014-4877 for CentOS-5 hosts is to add 'retr-symlinks=on' to /etc/wgetrc; for CentOS-6 and CentOS-7 you should run 'yum update'

whatisit

For a more in-depth description of both CentOS the product and CentOS the project please see http://www.centos.org/about/ and http://wiki.centos.org/FAQ/General

whatweship

This venue is only able to support what the CentOS project ships. If you install a package from a source other than the CentOS project you will need to seek assistance with that package from whence you received it.

whining

Repeatedly complaining about something that you got for free will very likely end up with you being unable to speak in the channel

wiki

The CentOS wiki is located at http://wiki.centos.org

wine7

As an interim solution until EPEL makes their wine packages available you may get wine for CentOS-7 from http://arrfab.net/attic/RPMS/7/x86_64/ = please do note that these packages are not signed, however they are being made available by a CentOS project member.

yumerror

Please put the _entire_ output from the yum command that is being problematic on http://pastebin.centos.org/ - include the command prompt where you enter the command right through to where it returns

yumsecurity

The official position of the CentOS project on the yum-plugin-security is that the project does not test for CVE closure on updates so does not publish the necessary metadata for the security plugin to function. If you require such validation you are encouraged to use RHEL.
