For configuring authorized keys for public key authentication, see authorizedkeys. The OpenSSH server reads a configuration file when it is started. Usually this file is etcsshsshdconfig, but the location can be changed using the -f command line option when starting sshd. Some organizations run multiple SSH servers at different port numbers, specifying a different configuration file for each server using this option. The default values for certain configuration options in OpenSSH are quite restrictive and often need to be changed. Usually this is done by editing the default configuration file to change just a few options. Contents Relationship of configuration files Common configuration options for individual use Common configuration changes for the enterprise Cryptographic policy Verbose logging AuthorizedKeysFile location Root login Login banner Port forwarding Certificate-based authentication Detailed sshdconfig file format Relationship of configuration files The SSH server actually reads several configuration files. The sshdconfig file specifies the locations of one or more host key files (mandatory) and the location of authorizedkeys files for users. Common configuration options for individual use Many individual developers and power users wish to maximize their convenience rather than go for maximum security. For such use, we recommend the following settings for homes, development servers, and universities. PermitRootLogin yes Common configuration changes for the enterprise Larger enterprises, or others wanting to run a tight security policy for certain servers, may want to configure the following configuration options. Cryptographic policy Symmetric algorithms for encrypting the bulk of transferred data are configured using the Ciphers option. Host key algorithms are selected by the HostKeyAlgorithms option. Key exchange algorithms are selected by the KexAlgorithms option. In particular, we do not recommend allowing diffie-hellman-group1-sha1, unless needed for compatibility. Using it could expose connections to man-in-the-middle attacks when faced with such adversaries.
