My shell doesn't get inputs!

It could happen that, after system upgrade or "hacking", your terminal emulator like gnome-terminal maybe presents a message like this:

readline: warning turning off output flushing

The solution may be the following: it is necessary to check the rights on pseudo terminal pseudo-device:

marco@IbmSolaris:~$ ls -lL /dev/ptmx

If the output you get is not the same like this

crw-rw-rw- 1 root sys 11, 8 2010-01-26 15:31 /dev/ptmx

you should be able to use xterm to change them. See man pty for more.
