Telnet into Dreamcast?
Jeos wrote to us with a fun Saturday afternoon project: "OK so today I was bored, and I did what anyone with a Dreamcast and a portscanner would do, I did a port scan on my Dreamcast. The results are interesting"-click below to read more.Update: 09/12 08:02 by H : Yes, this is a hoax - or sources from inside Sega say it is.

The OS fingerprinting didn't guess the OS, big surprise, but the interesting thing is all the ports that are open. The ones that interested me the most were 23 and 80, the normal telnet and web server ports. I tried to connect to my Dreamcast with a web browser, no luck there. Then I tired to telnet into it, jackpot! I was able to telnet in, and prompted to give a username/password. Of course I had no idea what the username or password would be, I wonder if it's some sort of backdoor for Sega?
Now i have to see if I can do anything interesting with the other ports.

I'd like to see some of the documentation that says a Yamaha CDR can burn a GDR on a standard CDR disc. Have any of you actually seen a GDR? The GD-ROM is actually written in two sessions. There is a single density session near the center of the disc that can be read by any CD-ROM drive. The majority of the disc however is a high density session that is on the outer part of the disc. This is achieved by using a proprietary compression format. The high density section is also read from the outer edge of the disc inward, instead of from the inner edge outward. Also, GD-ROMs currently CAN NOT be burned on regular CDR machines. Burning a GDR currently requires a special Sega produced machine. A standard game disc takes approximately 1.5 hours to burn.
Ok so from previous posts we know that they are filtering the 12345 etc ports. Thus stopping BO and other such harrasment. We also know he is connecting through his school. Now what ports are 'open,' well it's the 80 and 23. To follow up we all know what 80 and 23 are used for. The simple answer is that his school is blocking these ports so you can't run servers. In fact I'm suprised that 21 isn't showing the same thing. We see that nobody else is getting this, and with his web broswer open he was useing the other ports for the browsing, notice they are not filtered. Come on people we are smarter then this.
Is what seperates a Hacker from Users. Natural curiosity.
So if I'm the first person to crack into the dreamcast and change its files, do I get to keep it? (a la LinuxPPC :)
This little article really started to make me think about the possiblility of companies and their control over almost anything that they want to sell. I've seen the many articles on SlashDot about this topic, but this never really hit home until I saw some concrete evidence (at least in my opinion). Very interesting..
It's a shame that the docs of the hardware don't cover this or at least give some insight into why those particular ports are open, etc.. I think users that actually spend hard earned money (or not so hard earned) to buy the product deserve to know.

Here's the nmap -v against my Dreamcast on the net via ppp at the ISP Best.com: [root@pocket tm]# nmap -v 205.x.x.x Starting nmap V. 2.3BETA5 by Fyodor (fyodor@dhp.com, www.insecure.org/nmap/) No tcp,udp, or ICMP scantype specified, assuming vanilla tcp connect() scan. Use -sP if you really don't want to portscan (and just want to see what hosts are up). Host (205.x.x.x) appears to be up ... good. Initiating TCP connect() scan against (205.x.x.x) Adding TCP port 113 (state Open). The TCP connect scan took 40 seconds to scan 1487 ports. Interesting ports on (205.x.x.x): Port State Protocol Service 113 open tcp auth Nmap run completed -- 1 IP address (1 host up) scanned in 40 seconds. Note: the browser was on irc at the time, which is how I figured out the IP address, and probably why port 113 was open (for username authentication) Why the heck would a Dreamcast let you telnet in anyway? It's not like you can store files on a Dreamcast, or run apps remotely... Toshi
just call up sega and say you want the username and password. maybe they'll give it to you...
hopefully its not a defualt username and pwd for every machine...

If the DC was behind NAT/MASQ the IP would show
up to be the router that does the NAT:ing.
The open ports are consistant with this (telnet, BGP4, http), all are services that are running
on pretty much every cisco router.
Accually I think the sega rep does, he just wasn't expecting such a question and probably didn't realize there was a telnet port open on the dreamcast.
a: no. i tried scanning for open ports on my dreamcast, i saw telnet was open, and i tried using telnet to access it. i did this from my dsl-connected computer. i got the login and password prompt in the telnet window. the dreamcast works fine, even when i'm using telnet.
r: whoa, man. i dunno.
a: alright..
r: i couldn't give you any dns or anything
a: yeah?
r: that'd be ILLEGAL!
It seemed that he was starting to catch on towards the end there.
Did you try diconnecting your dreamcast and trying the port again? If it still works... it ain't your dreamcast. If it doesn't.. it MAY have been
Well, you might end up spending more mone for Visual C++ then you're dream cast (pluss running somthing like a webserver would be slow of a CD-rom). *but* you can code stuff for CE if you want, check out:
http://msdn.microsoft.com/cetools/ for more info. but I don't know if you would need to burn CE on the CD as well or not.
writing a CE application would probably be easyer then writing somthing that would actualy run on a DreamCast.
also, was the 'dream cast portscan' done while a game that used CE was running? I would think that nmap would detect CE. Or was it just the sega ROM that was scanned?

what would slashdot be without this post?
Actualy, I belive that work was done to get NetBSD to run on the thing, so you may not need to port linux.
I don't know how usefull the system is for *general purpose* computing (IE they spent all there money on sweet graphics chips). With built in networking it might be posible to build a beowulf cluster, but I don't know how easy it would be to get a program to run on dreamcast (Sega may have 'locked it down' to prevent game piracy, and unlicensd games)

i just wrote a quick cgi script on my linux box to print out the ip address of the client visiting it. I then went to the cgi script on the dreamcast, and telneted into it. didn't work. i don't have nmap installed, so I'm not going to telnet random ports, but i can tell you that i couldn't get anything out of port 23 and 80. And the cgi script worked right- the client address was different than my linux box's and was on the subnet my isp uses- so it seems to be pretty valid. gr, i hate bogus posts, especially when it gets all the slashdot readers all excited like that. ah well. -ethan
DHCP is a protocol used on ethernet LANs to do dynamic host configuration. ISPs use "dynamic IP" setups where RADIUS or TACACS spits out a random unused IP from a network for the user to use. DHCP is NOT used in dialup connections.
The Dreamcast comes with a 56k modem for internet game play and web browsing and the like (it actually includes an irc chat client which I thought was awesome).
The OS issue is not as clear cut. The dreamcast supports two OS's, and games are allowed to pick and choose which one they want to run on top of. A heavily modified version of WinCE is one choice, which should allow for easy ports of PC games (or rather, would make for easy ports to Win32 from the Dreamcast I would be willing to bet). The other choice is Sega's own proprietry OS, that is rumored to be based on the Saturn's OS. It would be interesting to know if the person who did this TCP/IP scan was running the web browser CD when he did this, or one of the games that supports internet play, such as Sonic Adventure.
Doesn't the Dreamcast run WinCE?
How many times do we have to explain it! This has been rehashed countless times over Slashdot, and al it really amounts to is FUD. Anyway, to explain it read this.
I have no idea what the name and pass is for the machines. We have never even heard about this...
I theorise no consperacies here. Although I acknowledge that games for console systems aren't developed on the consoles, bugs may arise at a later date.
I am willing to bet that the telnet entrance gives the user read-only access to registers, and maybe even snapshots of memory. Such tools could be useful to have memory snapshots show up in a web browser on the same PC as the development going on.
Unfortunately, I haven't followed the specs of the system, but I'll assume also, that Sega may exploit open ports with later addon products.
I don't personally have access to a Dreamcast of my own to experiment on, but let's have a little more information, please! A have a few questions about this article...
1) Through what means was the portscan performed? Was the modem attached to some sort of ISP or what?
2) What about the other protocols running:
23 open tcp telnet
80 filtered tcp http
113 open tcp auth
179 open tcp bgp
12345 filtered tcp NetBus
12346 filtered tcp NetBus
Did anyone try to access the web server and see what was open (if not exactly what happened)? What about the two "NetBus" ports? Is there a version of NetBus for WinCE (or whatever Dreamcast runs) that I don't know about? If people are concerned about telnet insecurities, wouldn't NetBus be a larger risk?
3) Has anyone attempted to brute-force their way through telnet, or any known exploits for the other protocols to check against a faulty implementation?
I find this information very interesting, but honestly I'm not sure whether or not I believe it without further details!
Your Brain + EEG + LEGO Robots = Brainstorms
I would suspect Sega enabled this feature as a way to debug the Dreamcast - I would also suspect most other console manufacturers do the same, only with proprietary hardware interfaces.
But what really interests me in how well the Dreamcast pulls off this 'convergence' thing that big companies like Microsoft, Sun, and others have been harping about. I mean, last year, these two companies were saying "We're gonna make it easy for everyone to access and use the Internet! Just watch!"
Here we are a year later and out of nowhere comes Sega with this console that not only plays some really great games, but also connects to the Internet and enables you to browse the web. But what's so special about that - I can hook up my computer's G400 to a TV display, too. The really cool thing is the power of the Dreamcast is hidden from the user.
Many of us here complaints that computers are too hard to use - there's no simple way to operate a computer like a television (push a button, and you're there). (We all know we hate these comments, but almost have to admit it.) The good thing about Dreamcast is that any John Q. Gamer (even their parents) can use this thing - they don't have to be computer literate! On the other hand, there's enough power in the device that real computer hackers like us can go to the length of making interfaces to the device (provided there are external ports and such) to harness that power - and the fact of the matter is, we will if given the chance.

You should never take life too seriously - You'll never get out of it alive.
What ISP are you dialing up through that you saw port 80 open? I've noticed that disturbingly Netcom/Mindspring has started diverting all traffic aimed at port 80 through a proxy server of theirs. I suppose nominally this is to improve caching and make my web browsing faster or something, but you can bet they're tracking everywhere I browse.
A side effect of this is that nmap will *always* show an open port 80, because when nmap sends packets aimed at port 80, they wind up going to Netcom's proxy server and not the intended host. Also means that if nmap is doing its fingerprint testing against that port 80, it will get the fingerprint of the proxy, not of the actual host.
If the machine you're portscanning from is going through a Netcom dialup, you're probably just seeing the port 80 on their proxy, and not on the dreamcast. The fact that 12345 and 12346 are also both showing up is also indicative that a router somewhere between your scanner and the dreamcast is doing some filtering/proxying/monitoring. Unless it's just coincidence, I can't imagine why Sega would open those ports.
Dreamcast USA version has a 56k modem inside and supposedly you will be able to purchase a 10 mbs ethernet card later before X-mas to play with all you friends ( it'd be neat if you could play Q2 at a LAN party with it ). To accomplish this it has to have an IP protocol stack. The parameters and source code for the current stack are actually free ( or sorta free ) if you download the Development Suite for WinCE from Microsoft's web site. Hey at least its cheaper to develop for the dreamcast than any Sony playstation machine.
The dreamcast itself does not run CE. CE was ported to the dreamcast so that developers which choose to use it (none do that I know of, but I may be wrong) can.
Since he was booting with the the web browser disc (I'd assume) it most likely is running CE however...
Very interesting. I do have (and use) the WinCe SDK, reading through the CE Builder SDK info the DreamCast is referenced a few times. The hardware OS is boot from GDRom only, all directX D3D, internet, etc.. is all disc specific. While possible it could be a back door, from a developer viewpoint its probably unlikly to be anything interesting.. as well as vendor and developer specific.
ATX1 duh we know that. We're talking about the dreamcast though, how do you even go about sending AT commands to it in the first place, noone yet knows (outside of Sega of course). And for some reason I doupt Sega has SLIP installed.
Jeos, as others have indicated you may have actually been probing your providers set up. There's not enough information to determine whether that is so or not. In that case be very careful about brute forcing it, if it is actually your provider that you're looking at they may become somewhat miffed.
If you're running a linux box it should be possible to set it up as a mini provider. You'd probably have to set up a DHCP server, PPP and telephony obviously. Your provider would then be taken out of the loop and the IP address of the dreamcast box would be easily detectable. If nmap or whatever still detected open ports you could be pretty sure that it was the real deal.
I think this is pretty interesting, I may run out and buy one just to check.
I can see where telnet would be useful for a game.
Debugging.
A programmer could telnet into the machine and look at or change variables, do step execution, etc.
Anyone who has done any embedded development can see the logic in this. Game consoles are, in fact, embedded applications. I used to work with ZWorld controllers that allowed me to monitor the execution of the software through the serial port. It was a godsend. IIRC, Sony's AIBO was debugged by telnetting into it.
Been way to long sense I've seen it done, but I believe you can simply hook up your dreamcast to your computers modem, dial out on the dreamcast and send an ATA to the modem on the computer. Then just run a ppp server. ok accually its not that simple as you have to force the dreamcast to ignore the fact there is no dialtone.. but if you can pull that off.
I checked the http server log for my site (dricasworld.com - complete coverage of the Dreamcast's online capabilities) and got a hostname of a Dreamcast user. Scanned it for open ports and none of those mentioned in the article were open. The guy either blundered and scanned the wrong IP or is full of it.
Hmm. It's running windows.... Try user: admin, no password ;-P
I called Sega a few muinets ago and asked for the U/P. Once I explained the Telnet thing, the customer service rep became *very* aggrivated, and said that Sega has left a lot of ports open, and the reason "will be announced at a later date". Right.
I thought this would make a good joke but then I realised it wasn't the least bit funny.

Fuck the system? Nah, you might catch something.
First of all if the telnet thing is real, its probably an easter egg not back door. I'd try "Joshua" as the username and see if it brings up War-Games. If Sega/the developer of the game wanted info about you it would send proprietary "game statics" through the net to some address. Secondly, people are asking about converting a DC into a "PC", the Saturn could take a normal PC keyboard with an adapter, I would think there would be a simlar thing for the DC. Since the GD-ROM use red laser tech to burn their disc, it should be posible for most CD-R drives to burn a GD, though it may take low-level control of the burning laser.
If the IRC server is run by sega, it is very simple to have the IP address masked (only for clients that connect to that server). I remember seeing an "anonymizer" type patch for an IRC server which gave the options to do just that... either have the form of
"UNIQUEID.anon.ircnetwork.com" or
"UNIQUEID.realnetworkname.com" where the hostname (first item till the first dot) was replaced by a uniqueid/sessionid... The IRC Ops can see the real information, and the log does contain the mapping info...
so to repeat... if they connect to a fixed irc server, then it is trivial to make the server hide the hostname info, or even "totally fake it"....

Here you go... most everything you'd want to know about copying a GD-ROM. GD-ROMS are physically no different than a CD-ROM, just the low-level formatting of the disc. So all you should need is the right software.

Dont know if they are or not.... But it would be a VERY cool move if they did.. think of it...
1-Dorm rooms with Ethernet
There are many of those cropping up every day
2-Cable modems (ethernet interface)
It would be worth it to pay the extra $5 to get a second ip for a dream cast since I already have a cable modem
3-ADSL modems (ethernet interface)
This would probably be a better bet than an integrated ADSL modem..
4-Home network
friends brings their dreamcasts to play multiplayer in a home lan.
5-LAN parties
If there is a Quake2 for the dreamcast, i have a feeling that it will quickly become the lan party tool of choice for many
an ethernet port opens up MANY more multiplayer possibilities... thus more sales... (of hardware and software).. [the question becomes; can the IP address be configured manually, or does it have to use DHCP; or will it use that autonegotiation stuff in 98 and macos; falling back to dhcp]

Let me get this straight; you have a new Dreamcast AND you were bored? That doesn't make the Dreamcast sound too enticing :)
The Yamaha 4416S will write "GD-ROMs" no problem... All you need is the software! :-) I know the 4416S, 6416S and above will do it, I'm not sure about the IDE drives though. Non-Yamaha drives will not write GD-ROM. I'm expecting GD-ROM support in software like CDRWIN this fall... Viv.
First off, AOL doesn't work with the DC. I forgot why, but it doesn't. Also, no, it doesn't use IE. It uses Planetweb's browser, more info here.
Don't underestimate AOL, we all hate them, but they're the biggest "ISP". There's already 300,000 Dreamcasts operating in the US and Canada, and that's one large and easy market for them to go after.

Their ads jokingly say that it knows everything about you, but maybe it's logged into some vast database Sega has assembled with everything about you.
Hmm... trading info back and forth between the machine and the server while you play. Major conspiricy theory stuff here ;-)

That still doesn't mean anything. Dynamic IP's get re-assigned, so it could well have been someone else's system you portscanned.
I think that was NetBSD, not FreeBSD. Free's the one that goes for servers on x86 (and somewhat on a Alpha/Sparc). NetBSD is the extremely portable BSD varient.

Ignorance is no excuse
Perhaps the ports are open for upgrade reasons. Consider the following scenario: Sega realizes there has been a small bug. They decide to release an upgrade for the operating system. They send registered users a letter telling them to go to a web site or whatever. The user goes, and from there, an applet connects to their dreamcast (from the server side), gets the system information from a telnet session by "logging in" and then the dreamcast spits back OS version info, firmware revision, etc, and then the applet uploads the correct operating system revision to the dreamcast. Is this possible?
Question 1 : The dreamcast comes with a web browser, and a 56kbs modem. It lets you set up a connection to whatever service you like, or you can use worldnet, which is Sega's "preferred provider". I'd assume that when you've got the browser up and running, you've also got these ports open so Sega can nefariously check your system out. Muah ha ha!
Question 2 : The Dreamcast CAN run Wince. It doesn't have to. Games load everything from the GD, so a developer could roll his own, go with sega's or go with Wince.
So far, the only wince game I've seen (Hydrothunder) looks Really Bad.
and there you are
According to this portscan, the dreamcast supports BGP! For those of you who aren't familar with BGP, it's a policy-based routing protocol used (for instance) at the NAPs.
So does this mean that Sega is going to start selling routing cards for the dreamcast? It's good to see that someone's finally working on an internet device that isn't just a client, but an affordable router! It's high-time I got rid of that crappy Cisco we have over here and replaced it with a fine piece of networking machinery, like a Sega. I'm so happy to see a router that's not just cheap - but you can also play games on!!!
Seriously, though, it does indeed appear that your ISP is doing something silly redirecting ports. This is particularly probably since nobody else can recreate this test. Either that or Sega chose a really bad port number to bind on.
Ok, what do we have here ? We have a machine that allows data input (the CD drive and the telnet port), remote access and data output (outgoing ports).
So far, we do not know how the stuff inside works. For example, we do not have any Dreamcast emulator. But this may happen soon.
IF we manage to understand the inner protocols of the system (after all, it has been done for the playstation, it is probably feasible for a WinCE machine, isn't it ?), then we might produce slightly modified CDs to have the console do rather cool things
Remote Dreamcast playing on your computer. Setting some mechanism to redirect display directives through the outgoing port, and accept commands from incoming. Ever tried a 20-players Destruction Derby over the internet ?...
This might work the other way round : by telnetting into the console and interfering with its display output, we might modify the look of the games at will - imagine : themes for your Dreamcast !
X servers for Dreamcast. Yeah. Now this may have implications that I cannot even imagine - or it may just be plain bullshit as well. I don't know. I don't even want to know. The very concept in itself (come on, X on a console !) is enough to make me wonder.

My browser disc didn't work so I returned the whole thing for a new one... everything works now except I cancelled the internet registration half-way through and now it thinks I'm registered. I can't figure out how to get back to registration so I guess I'll have to sign up on the PC to get my login information that way and manually enter it. It's not exactly ready for prime-time.

Ok heres a little more info on the Dreamcast, I was the one who posted.
I was running the web browser CD on the Dreamcast and I was dialed to my ISP, my university. I ran the port scan from my computer. I obtained the IP of the Dreamcast from a website which gives you your IP. It's possible this is wrong, but this is the only way I can think of to get my IP. As far as I know there is no direct way to get the IP, the Dreamcast doesn't tell you your IP.
I would like to try and find a l/p for it, although it'll be kinda hard since I don't even have a username. If anyone knows of a good brute force program for telnet let me know. My email is aminidab@mailcity.com.

> 2. Doesn't the Dreamcast run WinCE?
For what probably won't be the last freakin time, NO, the Dreamcast does not run WinCE. It CAN run WinCE.
I've finally had it: until slashdot gets article moderation, I am not coming back.
i called sega's dreamcast number (1-888-345-SEGA), they asked for my name and phone, and i proceeded to fake it:
:P
rep:can i please have your name and phone number?
aaron:doody doody doo!

a: well.. i was using my dreamcast, and i tried to telnet into it. it asked me for a username and password.
r: huh?
a: i tried telnetting into my dreamcast from another computer.
r: is telnet ppp?
a: huh?
r: do you know what ppp is?
a: yes. both computers are connected via ppp. the dreamcast is connected over modem and my computer is connected via dsl.
r: uhhhh...
a: anyway, could you give me the username and password?
r: you shouldn't need one.
a: everything works fine - thats not the problem. i just want to see what it does.
r: do you use at & t worldnet?
a: no.
r: well just go to "other" when you reboot, and that will tell you how to sign up. did i answer all your questions today?
a: well, no. that's not the problem, everythign works fine. there's no other number i could call?
r: you mean your isp?
a: no. for dreamcast.

r: okay...is your isp worldnet?
a: no. i tried scanning for open ports on my dreamcast, i saw telnet was open, and i tried using telnet to access it. i did this from my dsl-connected computer. i got the login and password prompt in the telnet window. the dreamcast works fine, even when i'm using telnet.
