ssh_config manual page lists incorrect default value of KexAlgorithms
Last modified: 2014-02-18 18:57:01 EST
Description of problem:
Manual page of ssh_config contains:
Specifies the available KEX (Key Exchange) algorithms. Multiple algorithms must be comma-separated. The default
is “ecdh-sha2-nistp256”, “ecdh-sha2-nistp384”, “ecdh-sha2-nistp521”, “diffie-hellman-group-exchange-sha256”,
“diffie-hellman-group-exchange-sha1”, “diffie-hellman-group14-sha1”, “diffie-hellman-group1-sha1”.
This is wrong as “ecdh-sha2-nistp256”, “ecdh-sha2-nistp384” and “ecdh-sha2-nistp521” are not implemented by RH's openssh.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. man ssh_config | grep ecdh-sha2-nistp256 || echo OK
“ecdh-sha2-nistp256”, “ecdh-sha2-nistp384”, “ecdh-sha2-nistp521”,
