Description Lukas "krteknet" Novy 2013-10-17 15:50:33 UTC
Description of problem:
Manual page of ssh_config contains:
     KexAlgorithms
             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):
openssh-client-5.3p1-93.el6

How reproducible:
Always

Steps to Reproduce:
1. man ssh_config | grep ecdh-sha2-nistp256 || echo OK

Actual results:
             “ecdh-sha2-nistp256”, “ecdh-sha2-nistp384”, “ecdh-sha2-nistp521”,


Expected results:
OK
