As with most things in Linux there are a couple of ways to do this.

for example, the user fred wants to gain access to a folder on 192.168.0.1 ......
sftp://fred@192.168.0.1/home/fred or
smb://192.168.0.1/shared/samba/folder
or more generically,
smb:/// or even
sftp://192.168.0.1/
Of course, if you want to use ssh, you could type:
slogin in the terminal.
