[Gumstix-users] Re: Server refused to allocate PTY (2.6.15 putty connection over BT)

[Terry M. <te...@av...>]

I also had this problem with ssh.  It seems to be a problem
with /dev/pts being mounted by fstab, then being overwritten by udev.  I
found a few other references to this problem, mostly with new migrations
to udev.  My sloppy solution is to create a script in /etc/init.d/ named
S10pts and which contains:

#!/bin/sh
# remount /dev/pts
mount -t devpts none /dev/pts

make sure to chmod it executable (755). Now /dev/pts will get remounted
and your pty's will get created. I'm not sure what the real solution is,
probably something in udev.....
