passwd characters

[Pradep]

Hi Friends,

Is there any limitation on HPUX, Linux or SOlaris on the type of characters which can be used in password ?
eg:- hpux telnet dont support @ and # in passwords.

thanks.
Sorry to ask about solaris !! :)

Right, @ and # cause problems because they are mapped to line kill and erase.

[Elmar P. Kolkman]

CTRL-H might also cause problems. As does a , CTRL-Q/CTRL-S, etc. And the CTRL-] (default escape character of telnet).

Also any character behind the 8th character might be ignored...

WARNINGS
Avoid password characters which have special meaning to the tty driver, such as # (erase) and @ (kill). You may not be able to login with these characters.

[Laurent Menase · Accepted solution]

you can use @ and # but you must put a \ to escape it.

else @ erase all the line
# erase the last character
so if password is a1#b2#
the result will be ab except if you type a1\#b2\#
