Those SHOULD be unique, but sadly, they aren't (and sometimes, they are missing entirely). Therefore, a USB serial number can't be used for authentication, but it could be used for "weak" identification - so it could be used to set a default user name or a default session, or to download a particular sessions file. Authentification and "hard" identification could be implemented using OpenPGP cards, ''scdaemon'' and a script based on ''/usr/share/doc/scdaemon/examples/scd-event''. For Status ''NOCARD'', suspend the session (kill x2goclient or send a signal that means "suspend", if available, or maybe sighup nxproxy), for status ''USABLE'', run ''gpg --card-status 2>&1 | awk '$1=="Serial" && $2=="number" {print $4}''' to determine the card's serial number, then act based on that (pull new sessions file or set default user, for example, and restart x2goclient). - FIXME Automount script currently expects a LUKS password in ''/etc/keys/keystick.key'' when it believes it has found an encrypted partition on USB media. This is a problem in general, as it should be trivial to sniff out this password using a rogue client. If we want to support this feature, though, we should add code to the build script that lets the user place a password file in the image, and sets proper restrictive permissions (this would have to happen right before the ''lb build'' call). Adding a boot parameter instead of hardcoding it would allow for dynamic password files (by specifying an URI that points to a CGI script, for example - you could output a different password depending on the source IP range, thus locking media to a particular department, if your departments have different IP ranges), but on the other hand, would make it even easier to sniff out the password. It would only really make sense for Netboot installations, and also not for a MiniDesktop in any way, because you have to block the user from accessing the TCE's local environment/files. And you also have to make sure that people cannot boot rogue clients. This means a DHCP setup that is locked to known MAC addresses, and physically blocking access to the ThinClient and its network wiring - because the MAC is displayed during boot, and thus trivial to clone. + FIXME Automount script currently expects a LUKS password in ''/etc/keys/keystick.key'' when it believes it has found an encrypted partition on USB media.

FIXME ''x2gocdmanager'' is currently not part of the image, but should become part of it. While optical media are on their way out, they still exist and thus we should support them. However, the script is hardcoded for X2Go-TCE-NFS and needs to be adapted to work with both TCEs. FIXME ''pinentry-x2go'' and ''x2gosmartcardrules'' probably need further investigation to make smartcard authentication work. -- This mail was generated by DokuWiki at https://wiki.x2go.org/

This file would then have to be sourced by the scripts, after they have extracted everything from /proc/cmdline. This will make adding the feature easier, by simply deciding that parameters from this file take precendence over boot parameters. One might argue that boot parameters should take precedence over the config file, but this sounds way more complicated to implement. ===== List of closed ToDos/FIXMEs for this page ===== * ''audioout='', ''blank='', ''*blankdpmsfix'', ''nodpms'', ''xinerama='', are currently unsupported in MiniDesktop-Mode, but this is being worked on, by outsourcing them into scripts under ''/etc/X11/Xsession.d/'' (currently, they reside in ''/lib/live/config/2900-x2go-thinclientconfig'' - which doesn't exist in the MiniDesktop branches - and from there, they get written to ''~/.xsession'' - fixed in github repo, soon in x2go repo - * It would be nice to have a boot parameter ''xroot=[0xaabbcc|URI1[|URI2|...]]'' for the desktop background image/color, and a boot parameter ''xrootmode=center|fill|scale|tile'' to determine how the image(s) should be positioned (if the parameter has been set, but something is wrong, it should default to the "grey mesh" background) - fixed in github repo, soon in x2go repo - * It would also be nice to have boot parameters ''xsaverimages=[URI1[|URI2|...]]'', ''xsaveridletime=n'', ''xsaverimgtime=n'', for a local, non-locking slideshow screensaver (if no images are specified/downloaded by the time it activates, it should just blank the screen). That way, one could display a slideshow without having to push the images across the network every time - fixed in github repo, soon in x2go repo - * Boot parameters ''blankdpmsfix'' and ''earlyblankdpmsfix'' still leave the screen blank for too long, when used in netboot mode (especially over slow links). Two ways to solve this are to either use local storage, or to use the initrd with the squashfs merged into it. A third, new option would be a boot parameter ''initrdblankdpmsfix'', where the un-blanking code of ''earlyblankdpmsfix'' is applied in the initrd already - fixed in github repo, soon in x2go repo - - * There might be a race condition between the scripts handling the sshd keyfile and the ssh private key file copy task (/config ...), causing one to umount the fixed disk before the other is done reading/copying. What's weird is that there already is code that is supposed to keep this from happening, but it doesn't. - fixed in github repo, soon in x2go repo * Setting the time via NTP will fail if the TC can't establish a connection to an NTP server via the internet. It would make sense to allow specifying an internal NTP server via a boot parameter. - fixed in github repo, soon in x2go repo * ''copysecring'' currently does not work in MiniDesktop-Mode, as it copies the keys to the wrong user's homedir. - fixed in github repo, soon in x2go repo * copying ssh private keys seems to fail in MiniDesktop-Mode - possibly because of the priming/pruning/cleanup action performed on the homedirectory by the minidesktop init scripts? - should already be fixed in github repo, soon in x2go repo -- This mail was generated by DokuWiki at https://wiki.x2go.org/
