NAME

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

SYNOPSIS

     blitz [-lT] [-s secret] [-k keyfile] [-f list] [-o RSOPT=] [files ...]

DESCRIPTION

     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.

OPTIONS

     -l      Server mode. The default mode is client.

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

     -k FILE
             A file containing the password.

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

     -o RSOPT=
             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.

EXAMPLES

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

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

     Copy '/etc/ssh/ssh*config' to /tmp/foo/etc/ssh/ on the server:
           $ blitz -s MySecret /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 -s MySecret /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 -s MySecret -o 'RSOPT=--bwlimit=10' /usr/./share

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

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

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

ENVIRONMENT

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

BUGS

     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.
