start ssh forwarding at bootup

The following command works fine in interactive mode :
#ssh -fNg -L 3306:localhost:3306 sciadm@mysqlserver

I have want to put in in daemon mode such that it can run everything when server boot up.

I have tried both method but does work. Any idea ?

1. put the following command in /etc/rc.d/rc.local - it will ask for password everything but in fact it connect through ssh key in real time.
       ssh -fNg -L 3306:localhost:3306 sciadm@mysqlserver
2. put the following command in /etc/rc.d/rc.local - it can start as background but it can't do the forward. In fact the command doesn't work in interactive mode as well
       ./autossh -M 3306 -fNg -L 3306:localhost:3306 sciadm@mysqlserver

Any advise that I can test further is appreciate.  Tks

The bootup scrip runs as root, in realtime you might use another user account to run that ssh command.

as the passwordless logins are per user you need to set it up for root aswell.

ansreas is correct, you will need to setup ssh keys for the root user to allow password-less logins.  It is against best security practices to allow remote root logins, I would be careful.

What example are you trying to do?  If you need to forward port 3306 to another server you are probably better off using iptables or something else that is designed for that function.

Can I setup the script to run as a specifc user, rather than the root .... due to security issue ..

You can run a command as a different user like so:

runuser -l  UserName -c 'command'
