How to monitor pty

Hi all,
today I could not telnet in AIX 5.2 cause I received the error
"telnetd: All network ports in use".

To allow users to telnet again I increased the number of ptys from default 256 to the new number 512.

To avoid the same problem in the future and for a better understanding, I need (and would like) to monitor and detect all the ptys in the system. I also need to know from which processes they are arised.

Someone can help me in this?

Thanks very much,
Luciano

Race condition with PTY

I've been experimenting with pseudo-terminals and found something I don't quite understand. Writing an EOF character to the master end doesn't work quite as I expect.

NAME
telnetrc, .telnetrc - Specifies setup commands for a telnet session SYNOPSIS
$HOME/.telnetrc DESCRIPTION
The .telnetrc file contains the setup information for a telnet session. It is a hidden file in your home directory and must be readable by the user logging in. The file can consist of multiple entries for each remote host to which a user can connect. A remote host entry consists of multiple lines. The first line is the name of a remote host. The subsequent lines must begin with blank spaces, and contain telnet subcommands. These sub- commands are processed as though they were typed in manually. Lines beginning with a number sign (#) are comment lines. See telnet(1) for a complete list of telnet subcommands. To specify subcommands that apply to all systems, create an entry, using the word "DEFAULT" as the system name, and specify the telnet sub- commands in the subsequent lines. EXAMPLES
The following shows a sample .telnetrc file: # Beginning of telnetrc file # Default subcommands that apply to all systems DEFAULT environ undefine USER # First system entry system1 set echo toggle crlf # Second system entry system2 set echo mode line toggle crlf FILES
User-customized telnet startup values. RELATED INFORMATION
