gnupg: Debugging Hints

 
 13.2 Various hints on debugging
 ===============================
 
    * How to find the IP address of a keyserver
 
      If a round robin URL of is used for a keyserver (e.g.
      subkeys.gnupg.org); it is not easy to see what server is actually
      used.  Using the keyserver debug option as in
 
            gpg --keyserver-options debug=1 -v --refresh-key 1E42B367
 
      is thus often helpful.  Note that the actual output depends on the
      backend and may change from release to release.
 
    * Logging on WindowsCE
 
      For development, the best logging method on WindowsCE is the use of
      remote debugging using a log file name of 'tcp://<ip-addr>:<port>'.
      The command 'watchgnupg' may be used on the remote host to listen
      on the given port (⇒option watchgnupg --tcp).  For in the
      field tests it is better to make use of the logging facility
      provided by the 'gpgcedev' driver (part of libassuan); this is
      enabled by using a log file name of 'GPG2:' (⇒option
      --log-file).
