SSH from iPhone to iPhone - Trying to transfer sms.db file

I'm trying to put together the terminal command so I can ssh to a friends iPhone and copy his 开发者_StackOverflow中文版sms.db file to my device. I'm using mobile terminal.

This is what I've put together so far.

scp root@IPHONE_IP_ADDRESS:directory_of_file directory_where_file_is_copied_on_my_device

scp root@192.168.1.102:/private/var/mobile/Library/SMS/sms.db /var

I'm then asked for password, I enter it and I get this.

 /var/sms.db: Permission Denied

Can someone tell me whats needed or what my mistake is? Thank you!

you need to setup the permissions properly (chmod) OR use a different folder with the appropriate permissions/rights.
