Each telnet-rlogin-ssh session requires a pseudo-tty master+slave, and a 2.4.x kernel for desktop use will generally be configured with 64 pttys. Try rebuilding your kernel with 128 or 256 pttys, depending on your ability to support the resulting user activity. There's more than one ptty implementation and the more modern ones can allocate arbitrarily many (subject to memory limits), so you may only have to ensure that you have more than 64 /dev/pty?? - /dev/tty?? inodes pre-created. Unless you're using the /dev/pts directory (filesystem type "devpts"), in which inodes will be created and deleted as needed. The whole can of worms is a little complicated. James F.
