   client itself is the router, or there is an IPv6 router advertising
128
   a network other than the one which the Mandos server is on.)
129
** Use a better value than 1024 for the default number of DH bits.
130
   This better value is either provided by a DH parameters file (see
131
   below) or an appropriate number of DH bits is determined based on
132
   the PGP key.
133
** Bug fix: mandos-keygen now generates correct output for the
134
   "Checker" variable even if the SSH server on the Mandos client has
135
   multiple SSH key types.
136
** Can now use pre-generated Diffie-Hellman parameters from a file.

158
* Client
159
** If client host has an SSH server, "mandos-keygen --password" now
160

161
   secure than the default "fping" checker.

** Network hooks.  The Mandos client can now run custom scripts to take
266
   up a network interface before the client is run.  Three example
267
   scripts are provided: "wireless", "openvpn", and "bridge".
268

297
   also affects the D-Bus bus and interface names (old names still
