generate ssh keys

% ssh-keygen -t rsa
Generating public/private dsa key pair.
Enter file in which to save the key (~/.ssh/id_dsa): (just type return)
Enter passphrase (empty for no passphrase): (just type return or enter a phrase)
Enter same passphrase again: (just type return or enter a phrase)
Your identification has been saved in ~/.ssh/id_rsa
Your public key has been saved in ~/.ssh/id_rsa.pub
The key fingerprint is:
Some really long string
% 


once you have generated it, 
run "cat ~/.ssh/id_rsa.pub". That will output the public key

wrong version of dbd ?? easy ./configure --with-incompatible-bdb

recently building a newer dogecoin daemon

a whole new process than :
make -f makefile.unix

instead being :
./autogen.sh
./configure
make

had a problem because it required an earlier version of berkeley db

i believe it was looking for berkeley db 5.1 and i have 5.3.
doesnt matter :)

it seems there are all sorts of switches huzzah

./configure --with-incompatible-bdb

wins the prize

compile zero coins linux daemons

             
              

need to make new folders.               

cd XCOIN/src

mkdir obj

mkdir obj/zerocoin

             
              

need to change permissions.               

cd src/leveldb

chmod +x build_detect_platform

make ... 

              

              

troubles.. should you attempt earlier unsuccesful compile, it can break later compile.

make clean -f makefile.unix
