      New program: pcapper · 7c154d1d
      Robert Ricci authored
      Runs on a node and uses libpcap to count packets going by. Opens a
      socket, so that remote programs can connect and, say, graph its
      output. The client gets to specify the interval at which it wants
      counts reported. Supports multiple interfaces, and multiple clients
      (with different intervals.) It can also write packet counts to a file,
      for analysis later.

      First pass at operational mode support for node states. · 4db415f5
      Robert Ricci authored
      Operational mode (op_mode in the database) affects the state diagram
      and timeouts for a node. Modes planned so far are:
      NORMAL    - Normal operation
      DELAYING  - Acting as a delay node
      UNKNOWNOS - Running an OS that does not report its state (OSKit kernels, etc.)
      RELOADING - Disk reloading
      
      stated now responds to to TBNODEOPMODE events, and sets database state
      accordingly. The set of state timeouts and valid state transitions are
      affected by a node's operational mode.
      
      The nodes table now stores information about operational modes, and
      the state_transitions and state_timeouts tables include the operational
      mode in addition to states.
      
      Next step will be to get the appropriate programs to send TBNODEOPMODE
      events.

      A fair amount of cleanup, both of the ssl stuff and of tmcd in general. · 40d072cf
      Leigh B. Stoller authored
      Deal with ssl/nossl clients; at Chad's suggestion add a small handshake
      tag to ssl enabled tmcc/tmcd which tells tmcd that it needs to enter
      full SSL mode. This allows old tmcc to connect to an ssl enabled tmcd,
      and still work okay.
      
      I've also ironed out the verification stuff. At the client, we make sure
      that the CommonName field of the peer cert maps to the same address that
      we connected to (bossnode).
      
      At the server, we check the OU field of the cert (we create the client
      certs with the OU field set to the node type; a convention I made up!).
      It must match the type of the node, as we get it from the nodes table.
      Also check the CommonName to make sure it matches our hostname. This is
      by no means bulletproof, but perfection is costly, and we don't have the
      money!
      
      Also cleaned up the REDIRECT testmode stuff. Instead of ifdef'ed under
      TESTMODE, leave it compiled in all the time, but only allow it from the
      local node (where tmcd is running). Mere users will not be able to
      access it, but testbed people can use it since they have accounts on the
      boss node.

      Leigh B. Stoller authored
      interaction with the user. The main point to note is that for the
      clients, there is a localnode.cnf and a ronnode.cnf. The difference is
      that I encode the type (pcron) in one of the extra fields so that tmcd
      can do a check on it. This is in lieu of per client certs, which would
      be a big pain in the butt right now. As we add other remote groups, we
      will create new config files. I bet this will change over time, as
      we learn more.
      
      Chad, it would be nice the tiptunnel cert could be generated from this
      setup.

      Add generation of per-project email lists, as per Dave's request. The · 8cac9c47
      Leigh B. Stoller authored
      lists are stored on users:/etc/mail/lists. For example, you can send
      email to ron-users@users.emulab.net. An alias entry is added (and
      newaliases run) if there is no alias in /etc/mail/aliases (by the proxy
      of course). There are two new options to genelists (on boss):
      
      	"Use the -a option to generate lists for all projects.\n".
      	"Use the -n option to generate lists for a new user.\n";
      
      With no options, generate the all users and active users lists
      (renamed to emulab-users and emulab-active-users). With the -n option
      (used by mkacct) regen the lists for all the projects the user is a
      member of.
      
      It would be nice to archive the email, but that requires a publically
      readable directory and a u+S archive file; the mailer daemon runs as
      user daemon, and the project tree is 770, so it cannot write the
      archive file. At some point we will have to go to majordomo or spam
      filtering, when the first list is spamm'ed. Sigh.

      Added SSL to capture (enabled with -DWITHSSL) · 2e536ba3
      Chad Barb authored
      To tip (or tiptunnel on a normal acl,) capture behaves the same.
      However, if a client connects and presents "USESSL" as the first six characters of their
      connection key, both sides initiate SSL negotiation.
      The server then attempts to get the key again. The second one is used for the check.
      
      SSL initialization is done on the first attempt by a client to connect via SSL.
      Capture assumes $(prefix)/etc/capture/cert.pem contains its certificate unless
      the '-c <certfile>' option is used.. if the certificate is not found or invalid, that
      connection fails, but normal connections will still succeed (and it will try to find the file
      again, next time an SSL connection is attempted.)
      
      On the client side, tiptunnel only uses ssl if there is a "ssl-server-cert:"
      property in the acl file. This is the SHA hash of the certificate that the capture server is
      expected to have (in hex.) If the certificate presented by the server does not hash to the
      same value, the connection is dropped.
