Happy New Year everyone,
I'm still looking for help with the correct configuration of my
pty's. My main questions are :
1) The kernel config has a line like :
pseudo-device pty 16 #Pseudo ttys - can go as high as 64
what if I want to use 256? I decided to experiment and I made
160 pty devices (using /dev/MAKEDEV pty{0,1,2,3,4}) and added the
appropriate entries to /etc/ttys. I restarted init and tried to
use the new ptys (I have an expect script that kicks off a bunch
of outgoing telnet sessions) - it failed after 14.
So I made a new kernel with 'pseudo-device pty 160', and 'config'
made a pty.h file that contained :
#define NPTY 1606
I went ahead and made the new kernel, and installed it - it runs and
I am now able to use all of my pty entries. So far, so good.
But I am concerned about the weird pty.h file and I'm wondering about
the comment in the kernel config file - what is the 64 limit?
BTW, this same comment is made in the FreeBSD Handbook section on
the pseudo-device 'pty'.
What am I doing wrong here?
2) The MAKEDEV script has the following comment :
# This still leaves [tuTU].
Do I just have to add the t,u,T,U pieces to the script to use these
ptys or is the support for these 'extra' pty devices in the code ?
I hope these questions aren't too stupid, but can anyone help me
see the light?
Thanks,
Craig
