There are more things than we know that can be revealed by your JPEG EXIF metadata such as the type of camera you use, aperture settings, the type of focus, lens type and even the location of the picture taken that might compromise the privacy of the persons or locations depicted in the photograph.

Exiftool
Install libimage-exiftool-perl
sudo apt-get install libimage-exiftool-perl
and by running the command
exiftool -all= *.jpg

Although it is a security risks, it is possible to make OpenSSH listens on multiple port.
To do that, you need to edit /etc/ssh/sshd_config file. and enable the “GatewayPorts” option.
AllowTcpForwarding no GatewayPorts yes X11Forwarding no #X11DisplayOffset 10
Look for the line that contain “Port 22”, and uncomment it if necessary, and add additional Port line to enable OpenSSH to listen to other ports. Like this:
Port 22 Port 80 Port 1025
The example will enable OpenSSH to listen to port 22,80,1025 simultaneously. Don’t forget to restart SSH service to enable the change by running :
sudo /etc/inet.d/sshd restart
Warning: Running SSH on multiple port may cause security risk, you have been warned!
