I increased the тАЬnptyтАЭ & тАЬnstrptyтАЭ parameters from 60 to 120 and sam reports that the usage of npty is 0 and usage of nstrpty is 62 but still we get the тАЬUnable to allocate pty on remote hostтАЭ
The system is 11.31.
Any ideas?
Thanks!
Tal

Re: rlogind: Unable to allocate pty on remote host.
Thanks for the prompt response, and yes, the system is after restart.
this is the output i get:
# kctune -v nstrpty
Tunable nstrpty
Description Maximum number of Streams-based pseudo-terminals
Module ptm
Current Value 120
Value at Next Boot 120
Value at Last Boot 120
Default Value 60
Can Change At Next Boot Only
# insf -v -d pts
insf: Installing special files for pseudo driver pts
Thanks!

Re: rlogind: Unable to allocate pty on remote host.
ls /dev/pts/[1-9a-zA-Z]* | wc
rlogind is using streams pty.
The other possibility is that you still have process owning the pts after the session end.
and ptm is closed.

Re: rlogind: Unable to allocate pty on remote host.
you still have application opening them
or ptm side.
so probably lsof may give you the answer.

Re: rlogind: Unable to allocate pty on remote host.
npty;
nstrpty; and
nstrtel - the number of telnet devices files the kernel can support for incoming telnet sesssions.
Just thinking out loud,
Rita

Re: rlogind: Unable to allocate pty on remote host.
npty -ptys driver -> bsd pty -> /dev/pty/tty*
nstrpty -streams pty -> /dev/pts/[:number:]
nstrtel -telnet pty ->/dev/pts/t*
They are all separate
