'id_rsa_bblc'的权限0644太开放了

Question

I am running a job in jenkins. But when I create a build I get below error.

Permissions 0644 for 'id_rsa_bblc' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
bad permissions: ignore key: id_rsa_bblc
Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,password).

While googling for a solution I found that I will have to change file permission to 400 or 600. So I tried to build job again after changing permission (using both 400 and 600) but still there is no use, the error still remains.

Please help me resolve this issue.

Answer 1

0644 in not supposed to be too open for a public key, but is too open for your private key.

Your private key should have permission 0600 while your public key have permission 0644.

By the way, you should also take care of the permission on .ssh folder. It should has the permission 0700, so that only you, the owner, has control over the folder.

As to your home directory, write permission is not supposed to be granted to group and others.

Run chmod go-w /home/username should fix that.

By the way, you should run this on the machine directly not via Jenkins.
