ssh перестал пускать

Система: CentOS 4.4 (Red Hat linux)

Собственно, проблема:

ssh (SSH-1.99-OpenSSH_3.9p1) перестал пускать под всеми пользователеми.

логины, пароли точно верные.

Сервер под управлением DirectAdmin

Доступ к DirectAdmin есть, на фтп заходит нормально.

Сегодня пытались поставить Яндекс.Сервер. Для его работы требовался 32

битный libstdc++.so.5 - поставили. После поставили Яндекс.Сервер.

Через некоторое время ssh перестал пускать.

Подозрения на то, что libstdc++.so.5 чего-то там с ключами мог

намудрить.
