OAА Строчка в /etc/cron.d/myscripts :
OAА */5 * * * * root /opt/rrd/stat/update.sh 21 /dev/null
OAА Вроде как рутом должен запускаться. У меня было смутное подозрение
OAА насчет ключей ssh, но как в этом достоверно убедиться и главное
OAА исправить :?
Как убедиться: ssh -v и не засовывать stderr в /dev/null. Тогда он руту
в почту все расскажет. Может быть, даже без -v расскажет достаточно.
Ну а исправить - в зависимости от того, какая ошибка была допущена...
Вот что падает в почту от крона:

И кажется я понял в чем проблема. Сервер, с котрого выполняется скрипт,
переустанавливался и на целевой машине видимо остался старый пабликкей
RSA. Надо попробовать скопировать пабликкей RSA заново.
