Section:
Installing Citadel
If you need to reconfigure any of these options later, you can use the following command:

1 dpkg-reconfigure citadel-server

This does not give the option to edit ports already set the first time you go through the config, need to add here:
/etc/default/webcit
to change http and https ports

Section:
Running Citadel
to start webcit you need to do:
/etc/init.d/webcit start
and not
webcit -d

Ok sorry Ive never submitted an issue so not sure if this format is ok,
Thanks

In the Linode shell guide, fingerprints are only given in MD5. For example, the RSA fingerprint for London's Lish gateway is 71:27:30:cd:dc:69:7a:fe:58:4a:04:e6:6b:5f:b4:e2

OpenSSH clients of version 6.8 or later request fingerprints provided in SHA256 format by default, instead of MD5. This applies to the latest Ubuntu. For example:

$ ssh -t <user>@lish-london.linode.com linode<number>
The authenticity of host 'lish-london.linode.com (178.79.153.61)' can't be established.
RSA key fingerprint is SHA256:L7sQgnpnoBwRoyIYXAFBs8SdSnwtyYmhXs1p/mQDKQM.
Are you sure you want to continue connecting (yes/no)? 

It's not obvious what the user should do in this situation. I recommend listing the SHA256 fingerprint as well.

As a workaround, you can force your SSH client to use the MD5 fingerprint like this:

ssh -o FingerprintHash=md5  # …etc

I do not have any experience setting up discourse, but I do have a great interest and a lot of experience setting up and working on linux servers.

A lot of time time, I enjoy writing documentation as I perform setup.

I noticed that linode was willing to pay folks to write documentation here.

Would linode like me to write documentation on how to set up a node for discourse?

Not sure if I'm posting this in an appropriate place, but... it would be nice to have this updated for the above, new upgrade level, and with more detail -- perhaps in an ancillary doc -- to cover the various std. LAMP config file upgrade options. I tried this procedure for the above version upgrade, and was foiled (I think) by some of the optional choices regarding whether to update various std. LAMP config files, etc.

I've tried a manual install from the Docker directions and also followed the directions here:

https://github.com/linode/docs/blob/master/docs/applications/containers/how-to-install-docker-and-deploy-a-lamp-stack.md

Either way the install locks at:

Setting up docker-engine (1.11.1-0~xenial) ...

Any idea if there are problems with 16.04? The same procedure works fine with 14.04.

In the two guides below it is mentioned that if you have chained certificates, you can add them all. This does not explain what that means nor the order in which you need to add them. Took me a little bit to figure it out. This is something that can be explained better.

in fail2ban we do not recommend to just 'cp jail.conf jail.local' and do modifications. .local files should provide only customizations, overriding settings in jail.conf. Please adjust the page accordingly.

The suggested file permissions to allow WordPress to automatically update it's plugins and themes are fine. They aren't working however to allow WordPress to update itself.

@cwlinode Interested in a Pydio file explorer installation guide for Ubuntu 14.04?

I have created a tutorial located in my fork. This tutorial walks you through installing the latest version of Nginx from the Nginx repositories on a Debian Wheezy system. Once the latest version of Nginx is installed an RSA private key is created and a certificate signing request is submitted to StartSSL. Once the certificate is issued, the example SSL Nginx virtual host is modified to begin serving HTTPS requests and support strong ciphers. Once the configuration is complete and Nginx is restarted the server will receive an "A" on the SSL Labs SSL Test.

Building upon this guide is another guide I am writing to add SPDY support, HSTS, OCSP, and a few other security best practices.

If you try to install docker on Debian 8, you get a warning and no clear way how to fix this:

     package.  We have no AUFS support.  Consider installing the packages

    + sleep 10

The solution is to use pv-grub and non-linode, but it took me a while to google that in random places. It would be nice if official tutorial mentioned this somewhere.

The one I'm looking is https://www.linode.com/docs/applications/containers/linode-lamp-container-docker and that command is step 1 and it says it should work with Debian.

Most people don't realize mod_php is not threadsafe, so I would mention it explicitly.

Similiar to https://www.linode.com/docs/security/securing-your-server the number of bits for the ssh key generation should be updated to 4096 bit using puttygen. (in https://github.com/linode/docs/blob/master/docs/security/use-public-key-authentication-with-ssh.md)

There are 308 links on 227 pages that have an id with the prefix sph_. Ive tried a couple of them at random and none of them seem to point to the correct section.

I can go through and replace them, but I want to make sure Im not removing something that is there for a reason.

Hi, I'm following the https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mysql doc, and the all was configured correctly. My concern is in the 'Test Email' section, says the following:

You should use Port 993 for secure IMAP, Port 995 for secure POP3, and Port 25 with SSL for SMTP

Is correct use port 25 to send an email ? Is possible use the port 25 with SSL ? I'am testing with swaks tool, but the server never request an user authentication.

In https://linode.com/docs/github-guide#commenting-and-editing-your-pr at the end it says

If you need to edit your PR, you can make changes to your locally saved branch, then upload the changes by following steps 5-9 of the Creating Your Branch section of this guide.

But there are only 8 steps in the said section.

Please look at docs/docs/security/firewalls/introduction-to-firewalld-on-centos.md.
In section "Firewall Zones", there is a misspelled word "seperate". It should be "separate".

A user on the forums had trouble with the troubleshooting section of the Longview Apache guide. He misinterpreted that he needed to have the less-than & greater-than brackets in his config. I agree with the confusion source.

We either can remove them or better explain it.

Re: https://forum.linode.com/viewtopic.php?f=10&t=12223&e=1&

Hi,

First of all, I want to say thanks to the author of the Email with Postfix, Dovecot, and MySQL guide. It was easy to follow and got me started on the road from Dovecot + local system users setup to one where I can easily manage users through a database. I've since been able to customize and tweak the setup to fit all of my needs.

That said, there is an issue with the guide that didn't bite me until I upgraded to Dovecot 2.2.x about a week ago. I've since learned that it is a bad idea to have the mail_location set to the same location as the virtual user's home directory:

Quoting the official Home Directories for Virtual Users Dovecot wiki page:

Home vs. mail directory

Home directory shouldn't be the same as mail directory. It's possible to do that, but you might run into trouble with it sooner or later.

So with the guide directing the reader to configure their setup like so:

userdb {
   driver = static
   args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n
}

mail_location = maildir:/var/mail/vhosts/%d/%n

The user will have their Maildir content dumped right into the root of their Dovecot home directory.

Some additional back & forth on the Dovecot mailing list (in case it's useful):

• http://dovecot.org/pipermail/dovecot/2014-October/098379.html
• http://dovecot.org/pipermail/dovecot/2014-October/098400.html

In my case when I used doveadm expunge from a cron job prior to the upgrade I didn't have any problems. It was only after the upgrade from v2.0.19 (default in Ubuntu 12.04 LTS) to v2.2.x that doveadm threw errors about finding .dovecot.lda-dupes files in the home directory for some of our virtual user's.

It didn't turn out to be anything serious from what I can tell, but it was enough to highlight that worse could happen at some point due to the configuration I was using. I propose that the guide be modified to recommend this configuration instead:

userdb {
   driver = static
   args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n
}

mail_location = maildir:~/Maildir

The userdb setting would stay the same, but the setting for mail_location would be changed from a static value to one that inherits the virtual user's home directory and places mail into a subdirectory. This would match the recommended values in the Dovecot configuration and should prove a safer set of default values for readers to adopt.

Looking over these guides it appears they use this same setup:

• https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mysql-on-debian-6-squeeze
• https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mysql-on-centos-5

and while they're not linked from the main Linode site (at least I didn't see them), the older guides that I found in the repo appear to also have the correct values:

• Debian 5
• Debian 6
• Ubuntu 9.10
• Ubuntu 10.04
• Ubuntu 10.10

These appear to have incorrect values:

• https://www.linode.com/docs/email/email-with-postfix-dovecot-and-mysql
  • This is the guide I followed
• https://www.linode.com/docs/email/postfix/troubleshooting-problems-with-postfix-dovecot-and-mysql

I'm not very familiar with Git or GitHub, but I was going to modify the source for the guide I used and the troubleshooting guide to show mail_location using the value that I mentioned above. Assuming that it would be accepted, how should I go about making a Pull request? Is there a preference on having one request per guide or should both be included in one request?

Thanks.

After Linode library was overhauled the following article shows a 404:

Running Apache with PHP-FPM on Debian and Ubuntu

Previously it was available at - https://library.linode.com/web-servers/apache/php-fpm/apache-php-fpm-debian-ubuntu

The wayback machine also has this one archived.

Hello there,

This is possibly not the best place to ask this, but is there a way to set a domains default email address? As in the email address unresolvable mail goes to? Perhaps that could be included in the guide?

Cheers

The Securing Your Server guide should probably use ufw instead of iptables in the Creating a Firewall section. The ufw syntax is much easier to understand for new users, e.g.:

sudo ufw allow ssh

... instead of:

-A INPUT -p tcp -m state --state NEW --dport 22 -j ACCEPT

Also, you don't need to manually create a script to start it on boot either.

I'd be willing to write this myself, just need to find the time. :)

Hey guys, these are just some notes of my most recent run through for this guide. Take what you like otherwise just close.

• Create the Virtual Machine: Step 4: This step doesn't need to be as long as it is. On first run, VirtualBox is smart enough to know that you don't have an install ISO mounted and will prompt you to choose one. I find going that route to be much faster than doing it manually as this step suggest. Also, doing it this way means VirtualBox will automatically remove the ISO after install as well.
• Disk image size: The latest release of the current LTS, Ubuntu 14.04.4 required more than 2GB for the disk size. Obviously this varies by distro but I predict the next LTS to be bigger than this one, so maybe the screenshot of a 2GB disk leads people on?
• upload command: I changed this out for something that will make the upload a bit fast (gzip and block size): dd if=/dev/sda1 bs=64K | gzip -c | pv | ssh [email protected] "gunzip -c | dd of=/dev/sda"
• There are no instructions here on how the user can have their distro use the Linode Repository Mirrors if they want to.
• I also took this opportunity to pre-load the distro with my SSH key so I can freeze the image and deploy from it whenever I want w/ access already.

I hope something here is useful.

The "Common Linux Commands" guide contains only an introduction and no actual content. It should be removed until it is complete, otherwise it is confusing:

https://www.linode.com/docs/tools-reference/tools/common-linux-commands

In the file docs/tools-reference/custom-kernels-distros/run-a-distribution-supplied-kernel-with-kvm.md, I think 2 things should be clarified:

1. There are two options for running a distribution supplied kernel.
   The "GRUB 2" boot option. Using this requires the root image to have a filesystem but no partitions. The grub2 setup seems to be hardwired to set root=(hd0) and prefix=(hd0)/boot/grub. This setup needs you to run update-grub to refresh the files in /boot/grub, but grub-install is not necessary.

   The "Direct boot" option. If your disk image has a partition table and filesystems on those partitions (e.g. a separate /boot) -- as is commonly done by many distro installers. In this case, grub-install must be run to install grub into the MBR of the virtual disk device.

2. When running such a BYO kernel configuration, Linode are limited in terms of the support they are able to offer.

Ubuntu 15.xx has some issues with the sample config

If you use 'table_cache=x* in MySQL 5.6 it wont start. You have to use table_open_cache instead.

Key_Buffer gives a warning , "[Warning] Using unique option prefix key_buffer instead of key_buffer_size is deprecated and will be removed in a future release. Please use the full name instead."

It should probably be noted that GMail only accept non-self-signed SSL certificates for secure POP3/IMAP connections. Self-signed won't work.

I didn't want to hack up the configuration files or my changes would be lost when I next distilled the config. Also, there is no official field to setting the SSL protocols. I then found the includes editor. This appeared to work correctly.

1. Go to Apache Configuration tool.
2. Select Include Editor.
3. Under Pre Main Include, select All Versions.
4. Enter this into the box: SSLProtocol All -SSLv2 -SSLv3.
5. Click Update.
6. Click Restart Apache.

Ok so I'm relatively knew to actually having a github account, so creating an issue may be the wrong way to do this.
However there's an additional troubleshooting step you need for the upgrade to debian 8 guide (docs/docs/security/upgrading/upgrade-to-debian-8-jessie.md) that I felt was worth passing on (especially for people who use something like virtualmin)

If you use quotas and come from wheezy at least, the quota package will still be installed but it'll throw all manner of fun errors about not being able to stat /dev/root/
After some digging, you have to create a symlink for it and recreate the quota file (someone may know how to back it up prior to the upgrade but it's too late for me sigh
ln -s /dev/sda /dev/root/

After that you can recreate the quota index & re-enable quotas:
quotacheck -cum /
quotaon /

Looking at the salt-states-apache-mysql-php-fail2ban.md file (this is the source file for the Salt States to Install Apache, MySQL, PHP (LAMP), and Fail2ban article?), the state definitions for the pkg.installed components could be written a lot more compactly. Typically, the lamp.sls would be written more like

lamp-stack:
  pkg.installed:
  - pkgs:
    - mysql-server
    - php5
    - php-pear
    - php5-mysql

and the extras.sls state would be written more like

fail2ban:
  pkg.installed

Or, if maintaining separate states for the LAMP and fail2ban installs wasn't a requirement, a single state of the form:

fail2ban-stack:
  pkg.installed:
  - pkgs:
    - mysql-server
    - php5
    - php-pear
    - php5-mysql
    - fail2ban

Could be used, instead.

The text in this guide for creating the info.php file is not escaped and does not display properly in Chrome or IE, causing the displayed information to be incorrect.

HTML: <p>sudo echo “<?php phpinfo(); ?>” &gt; /var/www/info.php</p>

Line of code that displays in the browser: sudo echo “” > /var/www/info.php

There is a disconnect in the naming conventions used for the CentOS/Fedora sections of the general static networking, and Native IPv6 guides:

While the "Linux Static IP Configuration" guide informs you to place your stanzas within /etc/sysconfig/network-scripts/ifcfg-static-eth0 [0], the "Native IPv6 Networking" guide asks for this file to be created in /etc/sysconfig/network-scripts/ifcfg-eth0 [1].

[0] https://www.linode.com/docs/networking/linux-static-ip-configuration#centos-7--fedora-20
[1] https://www.linode.com/docs/networking/native-ipv6-networking#centos--fedora

https://www.linode.com/docs/security/securing-your-server#basic-iptables-rulesets-for-ipv4-and-ipv6

The suggested firewall rules open port 22 (for SSH) on IPv4, but not IPv6 – is this deliberate or accidental?

In Copying a disk image to a different account (repo), 1746-migration3.1_small.png appears to be broken even though the file is available in the repo.

I was reading the tutorial "Email with Postfix, Dovecot, and MySQL" https://www.linode.com/docs/email/email-with-postfix-dovecot-and-mysql#creating-the-database and i think something in the step of creating the database tables can be done in a better way.

in "Creating the Database" https://www.linode.com/docs/email/email-with-postfix-dovecot-and-mysql#creating-the-database
The table "virtual_users" is created as such

CREATE TABLE `virtual_users` (
  `id` int(11) NOT NULL auto_increment,
  `domain_id` int(11) NOT NULL,
  `password` varchar(106) NOT NULL,
  `email` varchar(100) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `email` (`email`),
  FOREIGN KEY (domain_id) REFERENCES virtual_domains(id) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

I noticed that the field "email" is marked as unique, i think this is not the best thing to do, because this forces email "xyz" to be unique across all domains, which should not be the case.

So, i propose the unique key to be a combination of "email", and "domain_id" fields, this way the email uniqueness is enforced only over the domain, so an email of "xyz" can exist in more than one domain naturally.

So what do you think? and what are the steps should i take to apply this change? and should i apply it to all versions of this tutorial or only the main one?

In the following part of the guide:

timedatectl set-timezone `America/New_York`

The backticks cause an error. They are not needed and should be removed.

Hello,

In the dovecot/mysql tutorial (https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mysql), I may be wrong but I have an issue.

In the dovecot section, it is said at step 11, that permissions are to be root:mail

11. Verify that the permissions for */var/mail* are as follows:
drwxrwsr-x 2 root mail 4096 Mar  6 15:08 /var/mail

But on step 14, it changes to vmail:vmail

14. Change the owner of the */var/mail/* folder and its contents to belong to `vmail` by entering the  following command:
chown -R vmail:vmail /var/mail

So either step 11 is not required and should be only step 14 but if this is the case, shouldnt the value of mail_priviledged_group be "vmail" instead of "mail" at step 8 ?

mail_privileged_group = mail

So far, I only report it as is ; when going further and making my own tests, I will review it and if needed do some PR.

Thanks,
Nicolas

For earlier versions of dovecot, docs/security/security-patches/disabling-sslv3-for-poodle.md says one needs to patch the source code to disable SSLv3. I'm running dovecot 2.0.19 on Ubuntu 12.04 and disabled SSLv3 by uncommenting and adjusting my 10-ssl.conf file to be:

ssl_cipher_list = ALL:!LOW:!SSLv2:!SSLv3:!EXP:!aNULL

The ssl_cipher_list line that ships with the package is commented out and lacks the !SSLv3 element.

Regarding this guide.

I am very new to all this so I kind of blindly follow the instructions but after trying I found an article that contains a much more straightforward (and more up to date?) method.

Just in case it is relevant.

After following the great guideline I could get email out. After uncommenting smtpd_tls_wrappermode=yesI got it working on port 465

this is a where it happened: /etc/postfix/main.cf

 smtps     inet  n       -       -       -       -       smtpd

#  -o smtpd_sasl_auth_enable=yes
#  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING

I would like to write an article for hosting your own website on Linode using a static website generator called Pelican. They are much easier to handle than traditional CMS like Wordpress.

One of the similar frameworks already there in the docs is called Mango, which is also Python based but I think Pelican might be of its own interest as it is more popular in the community and very much configurable,

So, given these things, will such an article be right fit for the community?

Hello,

The section says that swapping process requires two linodes being shutdown. However, this blog entry states that swapping ip addreses is done on-the-fly. It needs to be updated (probably with new screenshots)
