unable to get ptty

[Rob Wallner]

While trying to do a xterm (Exceed) in to our head server.

I Tried: Insf -e


Permisions

-r-sr-xr-x 1 root bin 294912 Nov 14 2000 /usr/bin/X11/xterm
-r-sr-sr-x 1 root sys 299008 Nov 14 2000 /usr/bin/X11/hpterm

unable to get pty

together with your error message being a little obscure, you may be running out of pty allocations per your kernel parameter settings.

could you please execute this command from an already connected terminal or from server console, as root:

kmtune | grep pty

and post the output here ?

While trying to do a xterm (Exceed) in to our head server. i get a pop up that says

unable to get pty
Here is the output you requested.

npty 200 - 200
nstrpty 200 - 200

one more question then; actually three I suppose, technically. What is the output of these commands say

cd /dev ; ll -d pty*|wc -l

cd /dev/pty; ll -d pty*|wc -l

cd /dev/ptym; ll -d pty*|wc -l

HI,

It appears that dtexec is trying to execute a dtterm and the command is failing with a "Not a typewriter" error for grantpt.

grantpt relies on the system command, /usr/lbin/chgpt; therefore, you need to check the permission and ownership of this chgpt file.

NOTE: The permission and ownership should be:

-r-sr-sr-x 1 root bin 110592 Jun 10 1996 /usr/lbin/chgpt

Setting the correct ownership and permission on this file should allow your eXceed session to properly start a Dtterm window on your PC

Well, After a reboot of the servers, everyone can log in now.

Thanks for your help.
