If you're dedicating a serial port for use with -atariserver, you can add the following line to /etc/rc.d/rc.modules or -rc.local (as you prefer): - -/sbin/modprobe atarisio port=/dev/ttyS0 - -(Replace ttyS0 if you're using a different serial port, of course) - -If you need to use your serial port for other purposes, it's a little -less cut-and-dried. You will have to either manually modprobe and rmmod -the module as needed, or write yourself a script to do the job (possibly -also starting up agetty when the module is unloaded, or SLIP mode if -you're using FujiChat on your Atari, etc etc). - -#### READ THIS! #### - -By default, atariserver and atarixfer are installed setuid root, -group owner "users". This is done for two reasons: (a) so the programs -can access the /dev/atarisio* devices, and (b) so they can set POSIX -realtime scheduling mode, which prevents timing issues that can cause -SIO frames to be retransmitted or (on a loaded system) dropped. - -If run setuid root, atariserver and atarixfer will drop their root -privileges after setting realtime mode and opening the device. -There are no currently known exploits against atarisio, but the code -hasn't exactly been audited by the NSA either. - -You have several options here: - -1. The default. Simply run the script. On a single-user system, this is -reasonable, though it's the least secure. atariserver and atarixfer will -be setuid root, and runnable by anyone in the users group. - -2. Run atariserver and atarixfer setuid root, but restrict access to -some group other than "users". To do this, run the script as: - -# SETUID=yes GROUP=wheel ./atarisio.SlackBuild - -(replace "wheel" with any other group, as you prefer). -This option is more secure than option 1 and outperforms option 3. - -3. Run atariserver and atarixfer as a normal user. This can cause -performance problems, but on most setups it works OK (on some systems, -it may not work at all). To do this, run the script as: - -# SETUID=no ./atarisio.SlackBuild - -This should be more secure than 1 or 2. - -4. Same as 3, but extra paranoid: use a group other than "users" (I like -"wheel", but you could create your own "atarisio" group if you really -want), and be very picky about who you add to the group. - -# SETUID=no GROUP=wheel ./atarisio.SlackBuild - -Like option 3, this may cause performance problems or prevent the app -from working at all. |
