Setting Up dgamelaunch and WebTiles

WORK IN PROGRESS – Last edited by floraline 2018-06-14 [Build on Ubuntu 14.04/Debian9]

This document describes how to set up an official Crawl server with support for webtiles and console, automatic updates, Sequell/scoring integration, and public ttyrecs. If you just want to run a webtiles server for friends and coworkers, the process is much simpler: see webserver/README in the Crawl source.

For debugging issues related to this setup or a running server, see maintaining dgamelaunch and webtiles.

0. Create the users

Create the users crawl and crawl-dev, with their associated user groups. The former will be used for running crawl, and the latter for administering it.

~$ sudo adduser crawl
~$ sudo adduser crawl-dev

Write down the uid and gid for these users, you will need it later

~$ id crawl
~$ id crawl-dev

These groups and permissions will save a lot of headaches:

~$ sudo usermod -G root -a crawl
~$ sudo usermod -G root -a crawl-dev
~$ sudo usermod -G www-data -a crawl
~$ sudo usermod -G www-data -a crawl-dev
~$ sudo usermod -G crawl -a root
~$ sudo usermod -G crawl -a www-data
~$ sudo usermod -G crawl-dev -a root
~$ sudo usermod -G crawl-dev -a www-data

1. Set up chroot

Set up a chroot in /home/crawl/DGL/. On Debian-like systems you can do:

~$ debootstrap stable /home/crawl/DGL/

Ubuntu users should change 'stable' to match their build env (e.g. 'precise' for 12.04; 'trusty' for 14.04)

note from espais

If you are using Ubuntu 18, the default repositories list within chroot does not contain the appropriate sources. This will cause liblua5.1 to not be found. An easy fix is to copy the /etc/apt/sources.list from the server to within the chroot. For instance:

~$ sudo mv /home/crawl/DGL/etc/apt/source.list /home/crawl/DGL/etc/apt/source.list.bak
~$ sudo cp /etc/apt/sources.list /home/crawl/DGL/etc/apt/.

note from araganzar I believe you need to change source.list above to sources.list

2. Install prerequisites

Install some prerequisites into the chroot. Besides the base system that debootstrap installed, you need the libraries for running crawl, bzip2 for compressing save backups, the sqlite3 binary for interfacing with the user and version databases, locales, terminal definitions, and a minimal install of python (because character codecs are loaded at runtime). For Debian* systems:

~$ sudo chroot /home/crawl/DGL/	

This enters the environment in which crawl will run. After running this then install packages as root of the chroot:

~# apt update && apt upgrade
~# apt install bzip2 python-minimal ncurses-term locales-all sqlite3 libpcre3 liblua5.1-0 locales autoconf build-essential lsof bison libncursesw5-dev libsqlite3-dev flex sudo libbot-basicbot-perl

Xenial note: If you can't find locales-all or libbot-basicbot-perl, you probably need to enable universe packages with add-apt-repository universe && apt update. If you don't have add-apt-repository, you'll need to install software-properties-common, or edit /etc/apt/sources.list manually to enable universe packages.

note from araganzar On Ubuntu 14.04 I was unable to find locales-all even after checking universe is in sources.list. Was also unable to install the add-apt-repository package even after adding software-properties-common. Upgrading to 16.04 resolved these issues. You will also want to install vim and git using apt-get install if you don't have them. For crawl install, you also need to install libxtst-dev and libpng++-dev

Once all required packages are installed, generate locales and users:

~# locale-gen en_US.UTF-8
~# dpkg-reconfigure locales
~# adduser crawl
~# adduser crawl-dev

note from geekosaur

On recent Debian and derivatives with flex 4.x, you want the flex-old package instead of flex. You will get errors about undefined yylex during configure otherwise.

Change uid and gid to match the previous uid and gid:

~# usermod -u NEW_UID <username>
~# groupmod -g <NEW_GID> <groupname>

Exit the chroot.

~# exit

* Ubuntu is similar: ~# chroot /home/crawl/DGL apt-get …


  • If you're interested in reducing bandwidth at the expense of a little bit of rebuild time, you can install advancecomp and pngcrush on the host system. The makefile will automatically detect those and use them to optimise/recompress the tilesheets.

3. Mount /proc and /dev/pts

Various programs running in the chroot will need /proc and /dev/pts, so mount those. It's probably best to add them to your system's fstab so they're mounted on boot:

~$ sudo vim /etc/fstab

You can either mount the filesystems directly:

# Option 1: direct mount
proc      /home/crawl/DGL/proc       proc    defaults        0       0
devpts    /home/crawl/DGL/dev/pts    devpts  defaults        0       0

or use a bind mount to duplicate the host directories into the chroot:

# Option 2: bind mount
/proc       /home/crawl/DGL/proc     none    bind            0       0
/dev/pts    /home/crawl/DGL/dev/pts  none    bind            0       0

Either way, these lines should come after the existing entries for your host system's /proc and /dev/pts. Now you should be able to mount them with just the name.

~# mount /home/crawl/DGL/proc
~# mount /home/crawl/DGL/dev/pts

NOTE: Root can trivially escape a chroot using /proc/1/cwd !

You'll also need to make sure your 'crawl' user can write to /dev/ptmx inside the chroot:

~# chmod 666 /home/crawl/DGL/dev/ptmx

4. Create crawl-dev dirs

Make the directories /home/crawl-dev/logs and /home/crawl-dev/run, owned by and writable by crawl-dev. Unless noted otherwise, subsequent commands should be run by user crawl-dev.

~# su crawl-dev
~# mkdir /home/crawl-dev/logs
~# mkdir /home/crawl-dev/run

5. Download dgamelaunch

Check out the cszo branch of dgamelaunch and dgamelaunch-config as crawl-dev user. You might also want a copy of Sizzell if you intent to announce milestones and games in IRC.

# TODO: publish dgamelaunch and sizzell branches

~$ cd
~$ git clone -b szorg git://
~$ git clone -b szorg git://
~$ git clone git://

6. Build dgamelaunch

Build dgamelaunch; copy the binary into /usr/local/sbin/ on your main system, and the ee and virus binaries into /bin on the chroot.

~$ cd dgamelaunch
~$ git checkout szorg
~$ ./ --enable-debugfile --enable-sqlite --enable-shmem

Edit the Makefile and add -pthread to LIBS=:

~$ vim Makefile

Build dgamelaunch:

~$ sudo make VIRUS=1

If you get fatal error: curses.h: No such file or directory, edit the makefile and add -I/usr/include/ncursesw to CFLAGS=.

Copy the binary into /usr/local/sbin/ on your main system, and the ee and virus binaries into /bin on the chroot:

~$ sudo make install
~$ sudo cp ee virus /home/crawl/DGL/bin

7. Configure sudo access

~$ sudo visudo

Give user crawl-dev permission to run dgl binary with sudo. We'll also need permissions for a few additional scripts, as well as webtiles.

crawl-dev ALL=(root) \
  /home/crawl-dev/dgamelaunch-config/bin/dgl, \
  /home/crawl/DGL/sbin/, \
  /home/crawl/DGL/sbin/, \
  /etc/init.d/webtiles, \

If you want to use certain automated scripts, you will need to change the first line to allow this without a password:

crawl-dev ALL=(root) NOPASSWD: \

Security Note:

  • If crawl-dev has sudo privileges on a script that they have permission to edit, then they can edit the script to run any command as root.

You may also add permissions for your apache user (www-data on Debian) to execute the build scripts without a password. This is necessary for the /rebuild/ cgi script.

www-data  ALL=(crawl-dev) NOPASSWD: \
  /home/crawl-dev/dgamelaunch-config/bin/dgl update-trunk, \
  /home/crawl-dev/dgamelaunch-config/bin/dgl update-stable *

8. Configure dgamelaunch-config

Check out branch “szorg” of dgamelaunch-config and look over the various configuration files. You may wish to change directory names etc.

~$ cd ../dgamelaunch-config
~$ view dgl-manage.conf crawl-git.conf dgamelaunch.conf

You might want to remove the entries for rfk, atc, and boggle. If you do, also edit the menus under chroot/data/menus/ You definitely need to change the uid= and gid= lines in (the webtiles config) to match the numeric IDs of the 'crawl' user. Likewise shed_uid and shed_gid in dgamelaunch.conf.

~$ vim
  • Edit ip addresses, ssl certs, server names, which game modes you want to support, and run on port 8080 for non-ssl, make sure uid and guid of crawl user too!
  • Setting up SSL, assuming you know cert files, bundles or appending them as a .pem, and private server key
  • create directory www/crawl_ssl in the chroot. Store files there and point to /var/www/crawl_ssl/file in ssl options.
  • Make sure ssl options is set to None if you are not using ssl, or webtiles will not start
~$ vim crawl-git.conf
  • Change the gitourious link to this link:
~$ vim dgamelaunch.conf
  • Server name, shed_guid and shed_uid to be aligned with crawl
~$ vim dgl-manage.conf
  • Edit DGL_SERVER and uid to match crawl

Exit crawl-dev:

~$ exit

9. Create directories

Make the needed directories. There are a bunch, and I've probably forgotten some, but at the very least you need the following under the chroot /home/crawl/DGL/.

~$ cd /home/crawl/DGL
~$ sudo mkdir crawl-master
~$ sudo mkdir crawl-master/webserver/
~$ sudo mkdir crawl-master/webserver/run/
~$ sudo mkdir crawl-master/webserver/sockets/
~$ sudo mkdir crawl-master/webserver/templates/
~$ sudo mkdir dgldir
~$ sudo mkdir dgldir/data/
~$ sudo mkdir dgldir/dumps/
~$ sudo mkdir dgldir/morgue/
~$ sudo mkdir dgldir/rcfiles/
~$ sudo mkdir dgldir/ttyrec/
~$ sudo mkdir dgldir/data/menus/
~$ sudo mkdir dgldir/inprogress/

You will also need the following set of directories for each crawl version you will support:

~$ sudo mkdir dgldir/inprogress/crawl-git-sprint/
~$ sudo mkdir dgldir/inprogress/crawl-git-tut/
~$ sudo mkdir dgldir/inprogress/crawl-git-zotdef/
~$ sudo mkdir dgldir/inprogress/crawl-git/
~$ sudo mkdir dgldir/rcfiles/crawl-git/
~$ sudo mkdir dgldir/data/crawl-git-settings/

For example:

~$ sudo mkdir dgldir/inprogress/crawl-17-sprint/
~$ sudo mkdir dgldir/inprogress/crawl-17-tut/
~$ sudo mkdir dgldir/inprogress/crawl-17-zotdef/
~$ sudo mkdir dgldir/inprogress/crawl-17/
~$ sudo mkdir dgldir/rcfiles/crawl-0.17/
~$ sudo mkdir dgldir/data/crawl-0.17-settings/

They should all be writable by user 'crawl', and the morgues, ttyrecs, and rcfiles should probably be readable by your web server.

DO NOT chown the whole chroot: various programs and directories inside the chroot need to be owned by root or other users.

~$ sudo chown -R crawl:crawl crawl-master
~$ sudo chown -R crawl:crawl dgldir

Also create the file dgamelaunch directly under the chroot; it will be used as a shared memory key. Contents don't matter.

~$ sudo touch /home/crawl/DGL/dgamelaunch

If you want debug messages, also create the file dgldebug.log and make it writable for crawl. Warning, the file has a reputation of not being incredibly useful:

~$ sudo touch /home/crawl/DGL/dgldebug.log
~$ sudo chown crawl:crawl /home/crawl/DGL/dgldebug.log

Finally, ensure that user crawl has write access to /var/mail so that console messages can be sent.

9.5 Create directories Pt.2

Create the crawl versions database and the save and data directories for trunk:

~$ sudo /home/crawl-dev/dgamelaunch-config/bin/dgl create-versions-db
~$ sudo /home/crawl-dev/dgamelaunch-config/bin/dgl create-crawl-gamedir

Copy the resulting crawl-git directory for each other version you will support:

~$ cd /home/crawl/DGL/crawl-master
~$ sudo cp -a ./crawl-git ./crawl-0.17

10. Publish dgamelaunch configs

Publish the configs into the chroot (and the dgamelaunch config into /etc).

~$ sudo /home/crawl-dev/dgamelaunch-config/bin/dgl publish --confirm

11. Install crawl

Try installing your crawl versions (run as user crawl-dev):

~$ /home/crawl-dev/dgamelaunch-config/bin/dgl update-stable 0.17
~$ /home/crawl-dev/dgamelaunch-config/bin/dgl update-trunk


  • At the very least you must run update-trunk, because that is responsible for installing the webtiles server.
  • You probably want to set up a cronjob to run this once a day. if so, you will need to ensure your host has locales set correctly for webtiles to run.

Webtiles require an UTF-8 locale:

~$ sudo update-locale LANG=en_US.UTF-8

I add this line to the beginning, so I have a log of all updates:

   exec >> /home/crawl-dev/logs/update.log 2>&1

11.2 HTML templates

Currently, you will need to copy and edit the html files from the git repo to the templates directory in the chroot

~$ sudo cp /home/crawl-dev/dgamelaunch-config/crawl-build/crawl-git-repository/crawl-ref/source/webserver/templates/*.html /home/crawl/DGL/crawl-master/webserver/templates/

Exit crawl user:

~$ exit

12. Create symlinks

Set up symlinks in /var/www/ for people to access morgues, ttyrecs, etc. As root (or someone with access to that directory):

Create a folder named crawl

~$ mkdir /var/www/crawl

In /var/www/crawl, create symlinks

~$ cd /var/www/crawl
~$ sudo ln -s /home/crawl/DGL/dgldir/morgue/
~$ sudo ln -s /home/crawl/DGL/dgldir/rcfiles/
~$ sudo ln -s /home/crawl/DGL/dgldir/ttyrec/

12.5 Apache configuration

Some stuff for your Apache config. Note that and are installed into /usr/lib/cgi-bin by the dgl publish command. You'll need to enable mod-rewrite if that is not already enabled.

On Debian:

~$ sudo a2enmod rewrite
~$ sudo service apache2 reload

note from araganzar - Apache 2.4 and later has different access rules - You no longer use “Order allow,deny” and “Allow from all”, these should be replaced with “Require all granted” - or “Require all denied” if the 2nd directive is “Deny from all”

Restart apache

~$ sudo service apache2 reload

12.6 Start webtiles

Start Webtiles as crawl-dev via:

~$ sudo /etc/init.d/webtiles start
Troubleshooting Notes:
-Tornado error:
File "/usr/local/lib/python2.7/dist-packages/tornado-3.0.1-py2.7.egg/tornado/", line 153, in __init__
TypeError: __init__() got an unexpected keyword argument 'connection_timeout'
  • Need to install edlothiol's patch for Tornado. As crawl-dev, from /home/crawl-dev:
~$ fetch git:// into /home/crawl-dev/tornado
~$ git checkout http-timeouts-2.4
~$ python build

NOTE from johnstein:

/etc/init.d/webtiles sets PYTHONPATH for this, so you shouldn't need to install this, but I wasn't able to make it work and needed to ~# python install

NOTE from ZiBuDo:

Troubleshoot with sudo tail -f /home/crawl/DGL/crawl-master/webserver/run/webtiles.log
If latin1 encoding error: edit the final file in the trace and change 'latin1' to 'UTF-8'
If ascii encoding error: edit the files in the trace to have “from encodings import ascii” at the top of the file
If can't bind the websocket: make sure its trying on port 8080 and that crawl has proper permissions in the folders you created

NOTE from espais:

I have had an issue with dgamelaunch/WebTiles on Ubuntu 16.04 where the mounting procedure and permissions get trounced upon rebooting. To resolve this I added the following to /etc/rc.local (before exit 0)
  # unmount and remount pts/proc
  umount /home/crawl/DGL/dev/pts
  umount /home/crawl/DGL/proc
  mount /home/crawl/DGL/dev/pts
  mount /home/crawl/DGL/proc
  # fix ptmx permissions 
  chmod 666 /home/crawl/DGL/dev/ptmx
  # restart webtiles -- webtiles restart doesn't seem to work very well
  /etc/init.d/webtiles stop   
  /etc/init.d/webtiles start
  exit 0 # normally already in /etc/rc.local

NOTE from floraline:

I had an issue where I had enabled the built-in SSL options in WebTiles, and would start to consume 100% CPU time for several hours at a time. This was caused by clients, usually botnets doing port scans and other things, disconnecting in the middle of the SSL handshake. Tornado 2.4.1 does not handle broken SSL handshakes and will enter into a state where it uses 100% CPU and won't stop on its own. I fixed this by making the following change in tornado/, routine _do_ssl_handshake:
except socket.error, err:
-   err.args[0] in (errno.ECONNABORTED, errno.ECONNRESET):
+   if err.args[0] in (errno.ECONNABORTED, errno.ECONNRESET) or err.args[0] == errno.EBADF:
        return self.close()

13. Other notes

I'm sure there's more… launching the inotify watcher, crontabs for compressing ttyrecs, cleaning out old trunks, making logfiles and milestones available over the web, setting up an ssh user, set up a dgl-status script in cgi-bin, forwarding port 80 requests to 8080 for webtiles, etc.

13.1 user database

To create the user database, either run webtiles, or do:

~$ sqlite3 /home/crawl/DGL/dgldir/dgamelaunch.db
sqlite3> CREATE TABLE dglusers (id integer primary key, username text, email text, env text, password text, flags integer);
sqlite3> .quit;

13.2 ttyrec compression

For ttyrec compression (these files are huge, even when compressed), make sure you have the program lsof on the host, and run from a cron job (via sudo as crawl-dev):

#! /bin/bash
exec >>/home/crawl-dev/logs/compress-ttyrecs.log 2>&1
/home/crawl-dev/dgamelaunch-config/bin/dgl compress-ttyrecs

13.3 clean old trunk versions

For cleaning out old Trunk versions, run the following script from a cron job (as crawl-dev)

#! /bin/bash
exec >>/home/crawl-dev/logs/clean-trunks.log 2>&1


# tail -n +6 to skip the header and, more importantly, the most recent
# trunk version.
readarray -t to_del < <(
  $DGL remove-trunks -v | tail -n +6 | awk '$6==0 { sub(".*g","",$4); print $4 }'

if (( ${#to_del[@]} )); then
  echo -n "Cleaning trunks at "
  $DGL remove-trunks "${to_del[@]}"
  echo done.

13.4 dgamelaunch ssh user

Note that your ssh user should have /usr/local/sbin/dgamelaunch as their shell, and should have forwarding (particularly TCP forwarding) disabled. You could use the following at the end of your /etc/ssh/sshd_config (note that “Match” affects all options until the next “Match” or the end of the file).

Match User terminal
 AllowAgentForwarding no
 AllowTcpForwarding no
 X11Forwarding no
 PasswordAuthentication yes  # only if you want to allow passwords

13.5 dgl-status

Set up this dgl-status script in your cgi-bin with 755 permissions and root ownership (for debian/ubuntu, this is located at /usr/lib/cgi-bin). This script creates an easy-to-parse list of all the players.

#! /bin/sh

echo Content-type: text/plain
umask 0022
exec /usr/local/sbin/dgamelaunch -s

Send the URL to Wensley (on IRC freenode, ##crawl-dev, !tell Wensley the-url/cgi-bin/dgl-status)

13.6 inotify

Launch the inotify watcher which is necessary to populate the “current location” field in DGL.

~$ sudo /home/crawl-dev/dgamelaunch-config/bin/dgl crawl-inotify-dglwhere


  • The watcher has a dependency on the Linux/ Perl module. This is available in Debian as package liblinux-inotify2-perl.
  • If you add new inprogress directories (for new game versions) you'll need to find and kill that daemon then restart it.

13.7 stats caching

If you want your milestones, logfiles, and scores to be cacheable for stats, you will need to publish those files. Create symlinks for each file and put them in the appropriate folders in /var/www. Suggested directory structure:


with symlinks to each milestone, logfile, and score file (you will need to individually link each score file for each sprint map).

  ~$ ls -lt /var/www/crawl/meta/git/    
  total 8
  lrwxrwxrwx 1 root root 52 Jan  3 18:31 logfile -> /home/crawl/DGL/crawl-master/crawl-git/saves/logfile
  lrwxrwxrwx 1 root root 59 Jan  3 18:31 logfile-sprint -> /home/crawl/DGL/crawl-master/crawl-git/saves/logfile-sprint
  lrwxrwxrwx 1 root root 59 Jan  3 18:31 logfile-zotdef -> /home/crawl/DGL/crawl-master/crawl-git/saves/logfile-zotdef
  lrwxrwxrwx 1 root root 55 Jan  3 18:31 milestones -> /home/crawl/DGL/crawl-master/crawl-git/saves/milestones
  lrwxrwxrwx 1 root root 62 Jan  3 18:31 milestones-sprint -> /home/crawl/DGL/crawl-master/crawl-git/saves/milestones-sprint
  lrwxrwxrwx 1 root root 62 Jan  3 18:31 milestones-zotdef -> /home/crawl/DGL/crawl-master/crawl-git/saves/milestones-zotdef
  lrwxrwxrwx 1 root root 51 Jan  3 18:31 scores -> /home/crawl/DGL/crawl-master/crawl-git/saves/scores
  lrwxrwxrwx 1 root root 58 Jan  3 18:31 scores-sprint -> /home/crawl/DGL/crawl-master/crawl-git/saves/scores-sprint
  lrwxrwxrwx 1 root root 58 Jan  3 18:31 scores-zotdef -> /home/crawl/DGL/crawl-master/crawl-git/saves/scores-zotdef

It's recommended to also publish your rcfiles, morgue files, and ttyrec files.

  ~$ ls -lt /var/www/crawl
  total 12
  drwxr-xr-x 2 root root 4096 Jan  5 00:55 keys
  -rw-r--r-- 1 root root  348 Jan  4 19:31 default.asp
  drwxr-xr-x 4 root root 4096 Jan  3 18:33 meta
  lrwxrwxrwx 1 root root   30 Jan  2 01:33 ttyrec -> /home/crawl/DGL/dgldir/ttyrec/
  lrwxrwxrwx 1 root root   31 Jan  2 01:33 rcfiles -> /home/crawl/DGL/dgldir/rcfiles/
  lrwxrwxrwx 1 root root   30 Jan  2 01:31 morgue -> /home/crawl/DGL/dgldir/morgue/

sudo mkdir /var/www/crawl/meta/git/
sudo mkdir /var/www/crawl/meta/0.17/
Do this in /var/www/crawl/meta/git
sudo ln -s /home/crawl/DGL/crawl-master/crawl-git/saves/logfile
sudo ln -s /home/crawl/DGL/crawl-master/crawl-git/saves/logfile-sprint
sudo ln -s /home/crawl/DGL/crawl-master/crawl-git/saves/logfile-zotdef
sudo ln -s /home/crawl/DGL/crawl-master/crawl-git/saves/milestones
sudo ln -s /home/crawl/DGL/crawl-master/crawl-git/saves/milestones-sprint
sudo ln -s /home/crawl/DGL/crawl-master/crawl-git/saves/milestones-zotdef
sudo ln -s /home/crawl/DGL/crawl-master/crawl-git/saves/scores
sudo ln -s /home/crawl/DGL/crawl-master/crawl-git/saves/scores-sprint
sudo ln -s /home/crawl/DGL/crawl-master/crawl-git/saves/scores-zotdef

13.8 redirect port 80

to automatically make apache redirect webtiles requests for port 80 to 8080 (where webtiles runs by default) do the following (for ubunutu): This was noted in the full apache config above Create the following config file:

  ~# sudo vi /etc/apache2/conf.d/mysite
  <VirtualHost *:80>
  DocumentRoot /var/www/
  RewriteEngine on
  RewriteRule ^/crawl - [L]
  RewriteRule ^/crawl/morgue - [L]
  RewriteRule ^/crawl/rcfiles - [L]
  RewriteRule ^/crawl/ttyrec - [L]
  RewriteRule ^/crawl/meta - [L]
  RewriteRule ^/(.*)$1

Edit DocumentRoot and the RewriteRules for the morgues, rcfiles, ttyrecs, and milestones/logs/scores as required

then restart apache

~$ sudo service apache2 reload

13.9 admins

To add admins to the server (allows access to backup saves and wizmode!):

~$ sudo /home/crawl-dev/dgamelaunch-config/bin/dgl admin add <name>

14. Security notes

Security note: As long as crawl-dev has write permissions to the dgl script and its subdirectories, they can easily use their sudo access to run arbitrary commands. If they can edit and publish the dgamelaunch or webtiles config , they can trick the server into running arbitrary commands as arbitrary users.

If you want to give users the ability to manage crawl without giving them complete root access, move the whole /home/crawl-dev/dgamelaunch-bin directory to a system-wide location like /usr/local/lib, make it writable only by root, and update the sudoers entry and the various cron jobs and init scripts. The crawl-dev user then won't be able to change the server configuration, but will at least be able to use the various management commands (resetting user passwords, etc).
