@Wolf: Nice! I’m glad to hear you have figured it out. I didn’t think to check whether or not a port is blocked. Good call!

Well after several days of agonizing torture with this problem and soon before i almost gave up entirely i am happy to report i have solved this issue!

So as it would seem that port 23 on my machine was getting a “stealth” option meaning that all packets recieved to this port would be droped and i could not find what was causing this to open that port, so as an alternative i nano /etc/services and changed telnet to port 7777 and now it will connect

so anyone who is having a similar problem i suggest giving this solution a try as it may not be anythign but a simple firewall or some sort of internet security in your router (ie SPI) stopping you from getting those connections.

happy hacking!

well as a follow up i seem to be getting a lot closer and it seems all of my problems are rooting from dgamelaunch, it just wasnt copying files over even the “dgamelaunch” wasnt even in sbin
I have gotten a connection via local host now but as soon as i press play same error all over again, and i still cant get connection outside localhost even with tweaking the hosts.allow file to allow all telnet connection and even all connections ill keep working at this and if i actualy find a solution ill post but im slowly starting to lean towards looking for an alternative to dgamelaunch

yes i can start nethack from the command line and i did see however that cp was ommiting the directories and not copying them so i did a cp -r to fix this however now even with the terminfo the way it should be i am still getting the same error though telnet even as a localhost connect i get this.

Hmm… It sounds like it is crapping out at the moment when it should toss you over to the actual nethack console. Is nethack running properly on that machine? Ie. can you start it from the command line?

Also, did you make sure you copied all the files from /lib/terminfo?

well that was my fault lol, it was connection refused because it was ssh not telnet in putty

However….
nethack@ubuntu:~/dgamelaunch-1.4.7$ telnet nethack.game-server.cc
Trying 64.151.45.133…
Connected to nethack.game-server.cc.
Escape character is ‘^]’.
Connection closed by foreign host.
this is my actual problem as i was getting origonaly did this get figured out

Are you running that from the command line or pasting it into /etc/inetd.conf. Cause I think you need to paste it. Check the README file that came with dgamelaunch - maybe I have a typo in this line.

well i decided to rehash my vmware with ubuntulite and follow your tut word for word instead and i am pleased to say dgamelaunch works great and runs perfect

i did see those later as my missing libs in debian but had way to much difficulty installing them so thus i went with ubuntulite, which btw i love.

Now my big issue is telent when i use you commands i get an error saying -h isnt an option so i remove -h then i get another error saying -q isnt an option and so on till im left with -L but it still keeps telling me im using it incorrectly.

i decided to change it to telnetd instead of telnet in hopes that would be a small typo or something and it seemed to go through but however when i try to connect to the machine all i get is connection refused through putty.

if you have any further assistance on this it is appreciated but im sure ill get it eventualy…. im a very persistant person

thanks again for this wonderful article and my latest bookmark!

@Wolf: You just need to install the correct packages. Were you able to install the following?

- libncurses5-dev
- bison
- flex
- telnetd
- gcc
- make
- nethack-console

These files should be included there. Some of these packages may not exist in debian. Try apt-get search-ing for them.

If you did, see if you can do:

locate libdl.so.2
locate libdl.so.6

To see where these files are. If they are on your system they will show up there.

I am running kanotix on a VMware Workstation and attempting to run my own nethack server, i followed everything to the letter but a few things happened, first in

sudo /lib/libdl.so.6 /var/lib/dgamelaunch/lib/ sudo /lib/libdl.so.2 /var/lib/dgamelaunch/lib/ sudo /lib/libncurses.so.5 /var/lib/dgamelaunch/lib/

my terminal says these files dont exsist, but i pushed on anyways and i get to the end where i test it but all i get after doing a ./dgamelaunch is

Error opening terminal: xterm

should i try and use ubuntu like you did for my vmware install or can i get around this some how also tried this in a minimal debian install and got the same results. but with errors using “telnet” aswell.

could some one post me to a debian install for this or am i just doing somethinng wrong being that i am new to linux
