There are some points on that..
- Telnet is unencrypted and out of date - ssh is the protocol to go for sure.
- Trying to get a stable network should be the main task in this problem.
- You might want to check with the process list ps how a dead session is different to a working one. Maybe there is missing an attached process and PPID is different that to working sessions. By that you could set up a small script via cron, that kills dead sessions for clean up.
- There could be the one or other network option (see man no) that might be related to that, but I don't know if and which. Again, first 2 points of this list are the things to solve. Rest is just ugly workaround.

Hi folks. I have a quick question on using "telnetd" vs. "telnetd -a".
OS: AIX 5.x (5.1 through 5.3 ML3)
Some engineers at work want to stop using "telnetd -a" and use "telnetd".
(and of course, if I could get a cogent answer from them, I wouldn't be posting this question...) :mad:

telnetrc
telnetrc(4) File Formats telnetrc(4)
NAME
telnetrc - file for telnet default options
DESCRIPTION
The .telnetrc file contains commands that are executed when a connection is established on a per-host basis. Each line in the file con-
tains a host name, one or more spaces or tabs, and a telnet(1) command. The host name, DEFAULT, matches all hosts. Lines beginning with the
pound sign (#) are interpreted as comments and therefore ignored. telnet(1) commands are case-insensitive to the contents of the .telnetrc
file.
The .telnetrc file is retrieved from each user's HOME directory.
EXAMPLES
Example 1: A sample file.
In the following example, a .telnetrc file executes the telnet(1) command, toggle:
weirdhost toggle crmod
# Always export $PRINTER
DEFAULT environ export PRINTER
The lines in this file indicate that the toggle argument crmod, whose default value is "off" (or FALSE), should be enabled when connecting
to the system weirdhost. In addition, the value of the environment variable PRINTER should be exported to all systems. In this case, the
DEFAULT keyword is used in place of the host name.
FILES
$HOME/.telnetrc
