Two accounts need to be made: astrometry.net, and Trac.

(admin:) is something that has to be done by an existing team member. (new:) is something the new person must do.

• (admin:) create an account on astrometry.net. Add the user to the group astrometry.
• (new:) run htpasswd -nb <username> <password> to create the Trac username/password pair and send it to your astrometry.net contact.
• (admin:) add that line to astrometry@astrometry.net:trac/.htusers
• (new:) set up ssh.
  • log in to astrometry.net using your new username and temporary password: ssh username@astrometry.net
  • change your password with passwd
  • create an ssh key:

    mkdir -p ~/.ssh
    cd ~/.ssh
    ssh-keygen -f id_an
    cat id_an.pub >> authorized_keys
    

  • log out of astrometry.net
  • copy the new ssh private key back to your usual unix account:

    mkdir -p ~/.ssh
    cd ~/.ssh
    scp username@astrometry.net:.ssh/id_an .
    

  • edit the file config, adding this stanza:

    Host astrometry*
    Hostname astrometry.net
    User <username>
    IdentityFile ~/.ssh/id_an
    

  • now you should be able to log in to astrometry.net without having to enter your password.
• check that you can see the astrometry.net subversion repository:

  svn list svn+ssh://astrometry.net/svn/trunk
  

• if that works, check out a copy of the code. Depending on what part of the codebase you're working on, you may want to grab a subdirectory of the whole thing.

  svn co svn+ssh://astrometry.net/svn/trunk/src an
