проблема со шпатлевкой, вывода нет

У меня проблема с последней версией инструментов для замазки, собранной из исходников. У меня они работают нормально на некоторых серверах Red Hat, но не работают на других; Я не получаю результатов по всем инструментам. Пример:

Работает;

[root@server1 dir]# /usr/local/bin/puttygen -t rsa -b 2048 -C "tmp" -o /tmp/test

Re-enter passphrase to verify:
[root@server1 dir]#
[root@server1 dir]# /usr/local/bin/puttygen
Usage: puttygen ( keyfile | -t type [ -b bits ] )
                [ -C comment ] [ -P ] [ -q ]
                [ -o output-keyfile ] [ -O type | -l | -L | -p ]
Use "puttygen --help" for more detail.
[root@server1 dir]#

Не работает:

[root@server2 dir]# /usr/local/bin/puttygen -t rsa -b 2048 -C "tmp" -o /tmp/test

^C
[root@server2 dir]#
[root@server2 dir]# /usr/local/bin/puttygen
Usage: puttygen ( keyfile | -t type [ -b bits ] )
                [ -C comment ] [ -P ] [ -q ]
                [ -o output-keyfile ] [ -O type | -l | -L | -p ]
Use "puttygen --help" for more detail.
[root@server2 dir]#

Команда просто сидит там, пока я не выйду, она делает это для puttygen, plink и т. Д.

Чтобы добавить к этому еще немного, я установил hasgen для увеличения энтропии, но plink не возвращает данные. Пример запуска команды hostname через plink:
