Create a public ssh key, if you haven’t one already. Look at ~/.ssh. If you see a file named id_dsa.pub then you obviously already have a public key. If not, simply create one.
ssh-keygen -t dsa ItemMake sure your .ssh dir is 700:
chmod 700 ~/.ssh Get your public ssh key on the server you want to login automatically.
scp ~/.ssh/id_dsa.pub remoteuser@remoteserver.com: Append the contents of your public key to the ~/.
If you ever work on a remote servers network settings then this script may safe you from having to call support, and waiting on them.
When started/executed it
Sleeps first for 1 hour Then it renames the ”/etc/network/interfaces” file by adding the current time stamp to the end of the file It renames a file called ”/etc/network/interfaces.org” to ”/etc/network/interfaces” And finally it restarts the server. It also warns you a couple minutes before it does all that so you can terminate the program.
Why have more then one mail server? Or why even have a mail server at all, if you can use gmail? Well there are many reasons to have at leased one mail server, but having one on each server doesn’t make sense at all. I tried both ssmtp and msmtp, and decided on msmtp.
msmtp is an SMTP client. In the default mode, it transmits a mail to an SMTP server, which takes care of further delivery.
