For the old version of this homepage I have used CVS to update the websites. I have done this via SSH, which is pretty secure but has the annoying disadvantage of asking for a password for each operation. If you can trust the security of your client computer, there is a way to get rid of the password altogehter, without loosing security:
- Suppose the domain name of your server is server, and your login name loginname.
On the client, generate a public and private key.
ssh-keygen -C [email protected] -t dsa
When asked for a password, simply press return. The private key is stored in
~/.ssh/id_dsa, and the public key in
~/.ssh/id_dsa.pub. Never give the private key away!
Copy the public file to the server with
scp ~/.ssh/id_dsa.pub [email protected]:~/
Login on the server with
append the copied file to
cat ~/id_dsa.pub >>~/.ssh/authorized_keys
- If you want to enable this features on other servers, just repeat step 3 on each of the servers.
That’s it! If you have done everything correctly, the next time you login via SSH or use CVS over SSH, you will not need to enter a password yet you have a secure connenction.
