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.
- -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.
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
See

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
