Server refused to allocate pty

I know there is a thread on the subject but is not related to solaris so I am posting this question for help

I have a solaris 8 machine. I can log in through the console but when trying to log in through putty/telnet after accepting username and password it gives the follwing error

"Server refused to allocate pty"

Can any one pls suggest something on this.

You may need to increase the number of pseudo-terminals. See Solaris Tunable Parameters Reference Manual

Try the following commands,

# /sbin/MAKEDEV pty
# /sbin/MAKEDEV tty

I got the same issue with my Linux box when the udev update. HTH;)
