There are many folks that wouuld like to use the internet cluster system
during the contest and would like to integrate it with CT, NA, or TRLog.
This message will attempt to educate you on how this can be accomplished.
First requirement is what is called a "SHELL". This is simply a UNIX
type login to your ISP. Typically you connect to your ISP and negotiate
a PPP session. The ISP is "giving" you an IP address but you are not
logging in to any of the their computer systems. Most ISP's (us
included) do not like to give shells to customers. This invites hackers
to mess up your system. However, you may be able to get an ISP to change
their mind if you tell them what you are trying to accomplish. You need
to assure them that you are not going to issue any commands on their
computer. The only command you need is 'telnet'. You also need to tell
them that a "telnet program" will not help you since you are using a DOS
program with no cabability to talk through TCP/IP on the internet.
The second requirement is a modem. Hook your modem up to your computer
and tell your software that the "TNC" is hooked to the port the modem is
using. Bring up your packet window and type 'AT?'. You should get a
response like "OK". Now you are ready.
To connect to the internet cluster, bring up the packet window. Type in
ATDT###-#### (the number of your ISP). Once connected you should get a
LOGIN prompt. Type your user name and password when prompted. If you
have a shell account you should get a prompt like: /home/bill$ Once you
have the UNIX shell prompt you can telnet to the internet cluster of your
choice.
Now type in 'telnet cluster.akorn.net'. You will get a login prompt and
password. If the cluster is open, you will not need a password. Once
connected, you should see either 'DXC' or 'DX' as a menu choice. Type
whichever you see.
You are now connected! For the rest of the contest CT, NA, and TRLog
will think you are connected through a TNC and not a modem.
A few warnings...
1) NA's packet talk window only supports CAPS. This drives UNIX crazy.
I'm talking with Dave now about fixing this problem.
2) Hooking up two clusters on the same network may cause problems. I
know for sure it doesn't work with NA. I'm not sure about CT or TRLog.
3) If you do connect to two clusters, be careful you aren't sending
spots out on two nodes. Loops can occur which slow down the systems.
This is a quick message on how to do this... Most of this stuff is 2nd
nature to me so if I have confused anyone, please advise and I will
clarify.
