Where can I find more information? 1. Where is the known_hosts file? This file is currently placed in ~/.known_hosts_ibm. It is not placed in ~/.ssh because it is implementation-specific, and no standard defines a common place for SSH files (some use ~/.ssh and some use ~/.ssh2). Back to top 2. Why is a file such as ~/.ssh/known_hosts not used? This file is not used because it is specific to OpenSSH (see below) and no common file format exists. Back to top 3. Which cipher suites are supported? The most common cipher suites, including AES, ARCFOUR, TDES, and Blowfish, are supported. Back to top 4. Is compression supported? No; standard Java currently does not provide the necessary requirements for this. Back to top 5. Which authentication mechanisms are supported? Currently, the only authentication mechanisms supported are passwords. Back to top 6. Does IBM Secure Shell Library for Java contain a server API also? No, the server side is not supported; see below. Back to top 7. Where can I find an SSH-2 server? A complimentary SSH-2 server and a commercial version are available. Back to top 8. Where can I find more information? Further information is available at the Secure Shell site. Back to top
