Firewall Administration System (FAS)
Saving the Configuration
Save your configuration by clicking ‘Configuration’ ➝ ‘Save’ or ‘Save All’. If
you try to leave the configuration but have made modifications, you will be
asked if you want to save them.
The configuration is saved on the hard disk under
/var/lib/fas/<username>/configs/<configurationname>/floppy/
No normal user on the Adminhost can read this configuration. Only root
has the permissions to do this.
To create a floppy, insert one into the floppy drive, select the configuration to
save, then select ‘Configuration’ ➝ ‘Write Floppy’. Now the floppy is writ-

configured, which is shown by a green check mark in the left-hand side of
the dialog.

who created the configuration with ‘FAS’ ➝ ‘Login’ and enter the corre-
sponding password. FAS then lists all configurations created by this user.
Choose the configuration to edit from the list. Double-click the configuration
name in the list in the left window to edit one of the services in the corre-
sponding module.
Editing Configuration Files
Open the file editor with ‘Configuration’ ‘Edit Files’. You can modify config-
uration files directly with this editor. Only do this if you really know what
you are doing the effects your manual modifications will have. The FAS does
not check these modifications for correctness.
On the left, the overview window shows the main directories etc, root, and
sbin. The large window next to this displays the contents of the selected
main directory are displayed. Click a configuration file in this window to
open the contents of the file in the editor where you can modify them by
hand. Click a directory to list the files in it.
Via the ‘File Editor’ menu, create a new file or directory. Files can be im-
ported and entries be saved or deleted. With ‘Help’, access context-sensitive
