I want to mount iphone filesystem on my desktop but when am ready to use the ssh commands to get access i get the following

mainstxtrem@ubuntu:~$ ssh 192.168.10.7

mainstxtrem@192.168.10.7's password:

* i have Ssh Client Open and runing on my iphone terminal

Both Iphone and PC connected on the same mainrouter (should i change and assign a public device on iphone from the routers main Html page? ) or that is risk from outgoing atacks ..
