blitz — Securely transfer files between two workstations through NAT/Firewall.

       Efforts  have  been made to have blitz "do the right thing" in all its various modes. If you believe that
       it is doing the wrong thing under whatever circumstances, please notify me (skyper@thc.org) and  tell  me
       how you think it should behave.

Debian                                          October 12, 2020                                        BLITZ(1)

       The  blitz  utility  is  a  wrapper  script for gs-netcat and rsync. It allows one to send files from one
       workstation to another workstation via the Global Socket Relay Network (GSRN).

       A typical use-case is where both workstations are separated  by  a  Firewall  or  NAT  and  not  able  to
       establish a direct connection between each other.

       See gs-netcat(1) for a list of supported environment variables.

       Listen for clients with password 'MySecret':
             $mkdir/tmp/foo&&cd/tmp/foo$blitz-sMySecret-l

       Copy 'file.dat' to /tmp/foo/file.dat on the server:
             $blitz-sMySecretfile.dat

       Copy '/etc/ssh/ssh*config' to /tmp/foo/etc/ssh/ on the server:
             $blitz-sMySecret/etc/ssh/ssh*config

       It is also possible to limit the amount of path information that is sent as implied directories for  each
       path you specify. You can insert a dot and a slash into the source path, like this:

             $blitz-sMySecret/etc/./ssh/ssh*config
       The received files will be stored to /tmp/foo/ssh/ instead of /tmp/foo/etc/ssh.

       Copy recursively and limit bandwidth to 10kB/sec:
             $blitz-sMySecret-o'RSOPT=--bwlimit=10'/usr/./share

       Copy the entire root file-system:
             $blitz-sMySecret-o'RSOPT=-x'/

       Copy specific files read from standard input:
             $find.-name'*.conf' | blitz-sMySecret-f-

       Run a permanent server (daemon) through TOR:
             $blitz-sMySecret-l-D-T

-l      Server mode. The default mode is client.

       -ssecret
               A password chosen by the user. Both users need to use the same password to connect.

       -kFILE
               A file containing the password.

       -fFILE
               Read list of file names from FILE. If FILE is -, the list will be read from standard input.

       -oRSOPT=
               Options passed to rsync. See rsync(1) for available options.

       -T      Use  TOR.  The blitz tool will connect via TOR to the GSRN. This requires TOR to be installed and
               running. The IP and PORT of the TOR server can be set using environment variables.

       See gs-netcat(1) for more options.
