Добрый день!

Поставили на днях впервые FreeBSD 6.1-RELEASE
И сталкнулись с такой проблемкой:

ОС из под рута не пускает в некоторые директории,
например:

# cd /usr/home/username/tmp_
Warning: Cannot change to /usr/home/username/tmp_/

При этом в соседнюю папку (/usr/home/username/php) пускает.
Права стоят (одинаковые) правильные....

drwxr-xr-x   3 username  username   512 Jul  5 18:32 php
drwxr-xr-x  10 username  username  1024 Jul  9 12:20 tmp_

В чем может быть дело?

Самое интересно, только что узнал, что если зайти через шелл этим же юзером (username), не рутом.... то все равно в папку не пускает, та же ошибка:

Warning: Cannot change to /usr/home/username/tmp_/

А вот по FTP пускает.

Глюк проявляется только в bash'е

Спасибо.
Ага, в обновленной версии mc, этот патч уже идет. Т.е. глюк все-таки был не в bash, а в subshell'e mc.

Проблема решена.
