Re: cannot access /dev/pts/?

Could you elaborate? I'm having the same problem. My rootfs is NFS mounted
(to a Linux host). My /proc/mounts are the same. All /dev nodes are chown
root:root, and I have an additional "master" node /dev/ptmx (? not logged
into linux now). What is the magic missing node?

OK. I know the basics. /dev/pts needs to be mounted to access pseudo-
terminals in modern UNIX98 kernels.

I have enabled the CONFIG_UNIX98_PTYS=y option in my kernel and mounted
/dev/pts. See below.

-bash-3.1# more /proc/mounts
rootfs / rootfs rw 0 0
/dev/root / nfs
rw,vers=2,rsize=4096,wsize=4096,hard,nolock,proto=udp,timeo=11,retrans=2,addr=10.0.0.128
0 0 proc /proc proc rw 0 0
tmpfs /dev/shm tmpfs rw 0 0
tmpfs /tmp tmpfs rw 0 0
sysfs /sys sysfs rw 0 0
devpts /dev/pts devpts rw 0 0


I keep getting the "all terminals in use" when I try to telnet to my
board using several different builds of busybox. What other kernel
options or config files would be related to the error message above?"

I must use a 2.6.17 kernel because it is the only one that supports all
of my 3rd party drivers.



problem solved...When using embedded systems I don't like to use udev and
prefer to create static device nodes. Apparently I was missing a/some
required nodes in /dev.
