Problem with shell

[R.O.]

Hi all,

I need to avoid that when an user logs out from an application come into the operating system, and when the users log into the sistem, execute directly an application. I did it by put in /etc/passwd, instead of the shell a program which executes a shell with the command that launches the application:

In /etc/passwd: user1:..:..:..:..:/home/user1/launcher

Content of launcher:
/usr/bin/sh -c application

This works fine, but into the application there is an ftp, and it does not work when I execute the application of this manner. I don´t know how is this application. Does somebody have any idea of where could be the problem?

Best regards,

R.

Create a new login ID that is ftp only. Set the shell to /usr/bin/false and add the old login ID to /etc/ftpd/ftpusers.

Attached are documents outlining creating a restricted ftp user. We used the attached to create a number of ftp only accounts.

Best of luck.

Try to add /home/user1/launcher to /etc/shells, then you can ftp to this machine.

Or just use a standard account but make it captive, so it launches straight into your app.

eg, in .profile, put something like:

trap "" 1 2 3
exec /path/to/application

The trap statment stops them ^C ing out, and the exec launches their app such that it replaces the shell, so that when they quit the app, they log right out.

Hi,

Thank you very much, Graham. My boss suggest me the same solution as the yours and it is exactly what I wanted. So, 10 point for everyone.
Thanks too to the other people.
