I want box can auto ssh to another linux server when the box boot.

so I add script in init.d.
ssh -i /etc/dropbear/dropbear_rsa_host_key root@172.20.40.1

but it not working.
erro log:
Dec 29 23:40:12 OpenWrt user.info sysinit: Host '172.20.40.1' is not in the trusted hosts file.
Dec 29 23:40:12 OpenWrt user.info sysinit: (fingerprint md5 6e:d1:c6:e7:1c:12:72:e2:af:f6:af:46:21:e8:c3:9a)
Dec 29 23:40:12 OpenWrt user.info sysinit: Do you want to continue connecting? (y/n) ssh: connection to root@172.20.40.1:22 exited: Didn't validate host key

when I run above command at root. it can work fine.

resoved.
use "ssh -y" to Always accept remote host key if unknown.

I'm trying to SCP my way into another machine, and it seems like there is no option equivalent to that with SCP - any ideas?

I have put the pub key of the other machine in my ~/.ssh/know_hosts, but no luck. any other ideas?

thx

Thanks for this. and LR, to answer your question simply install...

opkg install openssh-sftp-server

and you will be able to use winscp or your choice of program to access files and transfer.

checking the source code of dropbear, to allow scp in /etc/rc.local or crontab,

you need add "export HOME=/root", so the /root/.ssh/known_host can be found.
