@ character kills me.

[Raul del Castillo_1]

Hello,
I have a terrible problem with the "@" character. Each time a log in a server, each time I type @ character, it deletes the line. This is in csh. If I change to ksh , the behaviuor is it prints the @ and return to the next line. Of course, in any other workstations I can type it with no problems.

What is happening?

Hi,
do a stty -a
and look for the delete line.
Then change with stty.
man stty should help explain.

As Peter mentioned stty is what you need
you can see by the command stty -a
and of course you may change according to your usage

Good Luck,

Hi Raul,

The proper solution is to not use @ in a login name nor PW. The system will interrogate the term type at login & the termcap definition will be used. Same goes for the # and & and * symbols as well. Just don't use them.

HTH,
Jeff

The user and password is given to the system before the system have had a chance to determine any terminal settings aso.

See man pages for getty to see which characters you must avoid in username/password.

The man page also explain a bit on the login process.

If you also see man passwd, you will see an advice to use 7-bit characters in password.

There is still some special characters to choose between, as well as the fact that unix differ between upper/lower case.
In total this should give sufficient variations for choosing a cryptic password...

This will also help avoiding problems due to changes to keyboard settings aso.
The 7-bit characters are normally easily available on any keyboard.
In my company we have several keyboard layouts and it would be a mess trying to guess for the appropriate key for a password which is not displayed...

-----------
a silly remark: a username with @
like f.ex. me@user
what should the mail address be... me@user@host.domain

HP-UX terminal settings default to using @ for a line kill (cancel the current input) and # for erase 1 character (like a backspace). This is the setting before you login. After login, assuming normal /etc/profile, /etc/csh.login and .profile files, after login your stty settings will be changed to normal. There is a special device file: /dev/ttyconf which can be used to set the pre-login defaults.

So for the one workstation, you may not be logging in 'normally', that is the login window is not a login window. The easiest way to fix this is to create a .Xdefaults file in all user $HOME directories, something like this:

echo "*loginShell: true" > $HOME/.Xdefaults

then start a new window with this user and you should see the change in the stty -a settings.

The solution was 'stty kill CtrlU'
