I have one server that I ssh into from my local box. From there, I control my other 40 servers by ssh'ing into them. Just took over for an admin who was worlds better than me and am having trouble now. I know the passphrase for the dsa key, and it uses it a lot of the time. But on a few connections, it uses the rsa key. Is there a way to choose which one is used by default? I found that I was able to accomplish this be renaming the rsa keys to something useless, but that feels cheap to me.

how do I choose between rsa and dsa for outgoing ssh sessions

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
