Ciao,
questo bollettino e' di interesse per chi utilizza le nuove
distribuzioni linux configurate con ax25. Da qualche tempo
a questa parte sono scomparsi i classici pty/tty.
Ecco come far riapparire i device.
Buona lettura e scusate se il bol e' in inglese.
Marco

They switched off the legacy pty/tty devices in the latest
linux distributions as it seems. Mandriva 2009.1, Ubuntu 9.04 Jaunty, etc.
(kernel 2.6-28 and 2.6-29)
I received an interesting note from Bernard, F6BVP this morning..
>Hi Bob,
>Actually I received a response from a Mandriva kernel guy only 14 minutes
after I posted the "bug" report !
>The explanation is very interesting for I did not know the trick.

>Other Changes
>LEGACY_PTY_COUNT is now 0
>Legacy pty (/dev/ttyxx) are still enabled in our kernel but we now create none
by default, to save several seconds of boot time. If you need some >for an
obsolete application, you can add the boot parameter pty.legacy_count=32 (or
another number depending on your needs).
This works also for Ubuntu 9.04 with kernel 2.6-28, etc as I tried this out
after receiving his mail.
Just open /boot/grub/menu.lst with an editor and add pty.legacy_count = 32 to
the boot line, like below and reboot
title Ubuntu 9.04, kernel 2.6.28-11-server
root (hd0,0)
kernel /vmlinuz-2.6.28-11-server root=/dev/mapper/linux-root ro quiet
splash pty.legacy_count= 32
initrd /initrd.img-2.6.28-11-server
quiet
So no need to recompile the kernel :=)
