Hey! I will give you some pointers on how to set up your Litecoin client for solo mining.

I'm writing this with the assumption that you are using Windows 7/8.

• Download Litecoin as normal, probably not necessary if you have it installed already. Might as well leave it closed for right now.
• Click start, type %appdata% and hit enter.
• Open the Litecoin folder.
• Create a new file called litecoin.conf. If you want to make your life easier, download this file (right click->save as..) which is exactly that. Or you can open up notepad and paste this:

rpcuser=username
rpcpassword=password
rpcallowip=127.0.0.1
rpcport=9332
daemon=1
server=1
gen=0block_nTime=1317972665
block_nNonce=2084524493

and save the file, be sure to change notepad's save output to 'all file types' and have litecoin.conf entered there. litecoin.conf.txt will not work! Also, I would recommend using notepad++ anyway.

Take note of the rpcallowip= line, that is the IP which can connect to the Litecoin wallet. If you are going to connect from external machines in your network, you need to specify their IP's. You are allowed multiple of these lines, so something like:
rpcallowip=127.0.0.1
rpcallowip=192.168.0.2
rpcallowip=192.168.1.*

Will work. I have tried using the asterik in there as a wildcard, and it worked. The username and password in the conf is self-explanatory, but if you want to connect your miners to something creative, now is the chance.

• Now you need to launch Litecoin. I think we can do this multiple ways. The surefire way is to open up a command window (click start, type cmd, hit enter) and navigate to your Litecoin folder. A really quick way to do this is to start navigating to the directory in windows explorer, and once you get inside the Program Files (x86) folder and you see the Litecoin folder, hold shift and right click on that folder and select "open a command window here", this will save you the hassle of navigating there. If you just open the command window right from the desktop, you have to go type:
  cd /
  cd p (hit tab until Program Files (x86) shows up, then hit enter) (if you are using a 32-bit OS, you will just go to the regular Program Files folder)
  cd Litecoin
  litecoin-qt.exe -server
  and then Litecoin will launch with the server flag on. You're all done!

  But I'm pretty sure we can achieve launching Litecoin a more efficient way.
