Playing online

There are several servers that host DCSS online, allowing you to play either by ssh/telnet or through webtiles.

There are three main benefits to this, especially if you join the IRC Chatroom.

  • Other people can watch you play live, and page you with messages and advice (the often ignored "hit _" that shows up...
  • Even if you repeatedly play Fire Elementalists, you'll encounter a more fun and diverse bunch of player ghosts to run away from and beat up on.
  • You can request replays (on of any milestone or death you know how to look up. It's great for reviewing where you went wrong, or reliving hilarious moments.

Windows - To properly play online in Windows, you're going to have to download a program called PuTTY. There is already a great thorough guide to connect to CAO here.

If you find yourself lagging, don't forget to enable SSH compression! Don't forget to set NetHack mode to ensure your keyboard works properly (very important for disabling traps)! Note well that this effectively changes what the keypad types, meaning the numrow will produce a different password than the keypad (for logging in to play once connected to CAO). One thing that guide doesn't mention is that you can "Disable Application keypad mode" under Terminal->Features. This allows you to use +-=/ to cycle targets. There's currently no working fix for allowing the numpad 5 to long rest. The only current method to perform a long rest online is by pressing numROW five.

A lot of people like to change their character sets to produce more 'solid' walls, and portals/shops that no longer look like wands/staves. All you need to do this is add the following line to your options "char_set = IBM" and change putty's character set to CP437 under Window->Translation->Received data assumed to be in which character set.

On Gnome and KDE desktops, and other terminals supporting UTF-8, you can use "char_set = unicode" to enable it, resulting in nicer graphics.

You may also want to configure your terminal color palette to match the "official one" of the tiles version. The colors to set are:

    VColour(  0,   0,   0), // BLACK
    VColour(  0,  82, 255), // BLUE

Crawl.Akrasiac.Org (CAO for short) is a publicly accessible server running the latest stable Crawl version (Stone Soup-branch). It can be accessed Via SSH with the Username and password "joshua".

All games played on CAO are recorded, and all game logs are saved. Player ghosts are automatically pooled and hearsed to all accounts, so you frequently encounter the ghosts of other players.

The IRC bot Henzell reports milestones such as the killing of many uniques, entering new dungeon branches, and so forth on the irc channel ##crawl.


CDO is a crawl server located in Germany/Europe,, telnet port 345 or ssh port 22, ssh-username:crawl, (openssh) or (putty) Basic SSH connection to CDO directions for putty: grab the second key mentioned above and putty. On the basic session page, make sure ssh is selected, and put "" for the host name (no quotes, of course). The port should default to "22" automatically.

On Connection->data: enter "crawl" into auto-login username On Connection->ssh: check "enable compression" On Connection->ssh->Auth: browse for the private key file "cao_key.ppk" that you downloaded to your pc. Back on Session, type a name in the blank saved sessions field, and hit the save button.


CSZO is a new crawl server located in West Chester, Pennsylvania in the eastern United States. It hosts both Webtiles ( and console Crawl (ssh to with username crawl and either the CAO key (putty version) or the password crawlingtotheusa).

Ttyrecs and morgues are available for browsing at Note that the user database is separate from CDO and CAO, so you will have to register an account for CSZO.


CLAN,, is a server hosted by Aleksi and maintained by TZer0. It is located in Germany and serves both webtiles ( and console ( via SSH (port 22): username “terminal” – password “terminal” or SSH-key: PuTTY key Unix key) for trunk and stable versions. Accounts and save files for SSH & WebSocket are shared.

CBRO, [1], is a server located in Atlanta, Georgia, USA. It serves the latest released version and trunk, via SSH ( port 22, username: “crawler”, SSH-key: PuTTY key Unix key) or WebTiles ( Accounts and save files for SSH & WebSocket are shared.

Rc files, ttyrecs and morgues are available for browsing at
