Hi Pavel, Thank you. I would really appreciate it if you can send me your programs... if you don't mind that is :) Pavel M. Penev [EMAIL PROTECTED] wrote: cut This here is absolutely wrong.

Netscape is responsible for handling the event, and it has no reason to kill its parent if run by a system()-like function, or run by exec*() function it will have its own signal-handling table. I have written two small programmes (one for GTK, and one to call it and trap signals). I can send them if you wish.

anyone knowledgeable enough pls help!
I'm going out of my mind when a user logs in a terminal this is what will happen: -automatically starts x-window, all keybindings and or hotkeys will be disabled, run netscape and it can't be closed without asking for the user's password. Can a script be used for this? and anyone kind enough to show me? Also, Maybe this can be done by adding/modifying xmodmap in the user's .xinitrc? if so, how? any help with be greatly appreciated. btw, what's the difference between keycodes and keysyms? Thanks in advance :)

Dont' stick to the Leave on password thing; make different accounts for the Kiosk- and normal users. The people who told you about the loop already gave you the solution for Kiosk mode users. The warnings about MIME (Java/ JavaScript/ Stylesheets) in Netscape are serious! If you want a more complicated and, as the whole thing runs as root, different approach, see the Kiosk (or was it Kiosk-Mode?)-HOWTO with detailled instructions. You will get the idea there. Another way: - run the loop as user - set the kiosk user's shell not to a real shell - don't use a window manager for the kiosk user - Hotkeys and so on are usually disabled in XF86Config's server flag section. Don't enable DontZap, you will never be happy without because Netscape is _far_ from stable. - use xdm and write the account name and password into its greeting msg so that any anonymous user can restart Netscape on his/her own - Write useful key combinations (CTRL ALT BS, ALT F7) onto the monitor... - Secure the user Netscape's preferences and bookmarks (root.kiosk 640, YMMV) - Don't forget to set up a part of the loop that removes all files that don't belong to Netscape, and Netscape's lock file (see the Kiosk HOWTO). - if you want them to be able to save pages to floppies, use autofs The whole thing will _definitely_ compromize security. btw, what's the difference between keycodes and keysyms? Can't help you in this respect. HTH Andre -- Andre Berger [EMAIL PROTECTED] from Bonn, Germany

For the starting of x-windows, I guess you could but startx in .login in the users home-dir. The netscape part it quite a bit more difficult ( I guess you can start it using .Xsession or something, but you'll have to check the docs of that for more info), the closing part, here the idea I got on that ( I can't provide it to you because I'm not good at c): Create a c-program that starts netscape and include signal.h that intercepts the SIGTERM, when the SIGTERM arrives the user is prompted for a password (netscape will be closed at that moment), if the password is correct, the program is terminated and netscape isn't running anymore, if the password is incorrect, netscape is restarted.

Thanks in advance :) I gues you already have enough good suggestions on the first two issues. Now for the password. I think you could create a firewall that would deny any X11 packets for closing netscape. Then you could add some tool that would request a password, and if it finds it acceptable it would change the firewall rules to permit netscape delete_event. You have a severe problem. You would need to read tons of documentation (esp. if you follow my suggestion). I would be curious to know if you succeed to solve it (and mostly HOW?). Sorry, I can't offer anything better, Pavel M. Penev

The function doesn't change if someone changes their key mapping with something like xmodmap. Keysyms, on the other hand, map between keys (in the user's mind) and numbers. For example, on a non-remapped keyboard, the Control keycode is 0x00E3 and Caps lock is 0x00E5. Their keysyms are 0xFFE3 and 0xFFE5 respectively. I like to switch my Control and Caps lock keys using xmodmap. The keycode of the key to the left of the 'A' key is still 0x00E5, but its keysym becomes 0xFFE3. Similarly, the keycode of the key 2 keys down is still 0x00E3 but its keysym is now 0xFFE5. Confused yet?
