Hello everyone!
I started playing with mods when a friend introduced me to the FeedTheBeast modpacks, and among the mods in the pack I play I found computercraft, and really enjoyed it, and I've been trying to learn more of how LUA works, while also putting the computers to good use.
A few weeks ago I decided I wanted a login system, so that anyone accessing the computers in my base would have to log in, but it would be best if it were controlled from a central server, so that it would be easier to update with new passwords and username.
So I created a test server in order to experiment with how to get this done. This led me to the following wikipage:
http://computercraft...oaming_Profiles
So i tried those codes, unfortunately it doesn't work. The initial [1] & [2] (Login or Shutdown) works fine, but once I've written the username and password, the computer sleeps waiting for the confirmation from the server, but doesn't recieve it, and declare invalid username or password due to timeout. I searched around trying to find other with similar problems, when I realized that all posts related to roaming profiles were several months or years old, and probably an older CC version.
I then started looking more into the wireless modems on the wiki (Yes, I were using wireless the whole time), and wondered if the standard rednet codes didn't work in favor of the new wireless codes, so I tried redesigning the program from the wiki to use the wireless codes (peripheral.wrap, modem.open etc. instead of the rednet codes (rednet.open, rednet.recieve etc.), only to realize I were a little over my head here, and got no idea what I were doing. So now I'm stuck with two different versions of the program that doesn't work.
So my question #1: Are the wiki codes outdated, or are they supposed to still work? If they're supposed to still work, then what is wrong with my programing?
Question #2: If version one is outdated, then what do I need to do to fix it? Are my own version #2 complete rubbish, or am I close to a logical solution?
Thanks in advance!
Regards
Joe
