That was the issue.

The utelnetd and my putty/telnet seem to be sending double enter per input.

it might be your client, what telnet client are you using?

windoze telnet? http://www.computerhope.com/telnethl.htm

anyway, extra local_echo should not affect the partitions that you create or delete,
it just looks irritating, that's all

I'm using both putty and telnet (from win XP)

and try to set/unset the LOCAL_ECHO

That don't seem to help.

Still it is 2 x ## when I do anything and press enter.

i am not sure why you are getting double echo...

there is a ssh server in D-Link firmware, you can give it a try
/usr/sbin/sshd
if it works you can ssh to your DNS-343 instead of telnet and hopefully solve your double echo issue

try starting it from the telnet session and see if it works, then change your fun_plug script

How do you start the SSHD on DNS-343?

Mine ended like this.

Code: [Select]
# /usr/sbin/sshd start
/usr/local/etc/sshd_config: No such file or directory

If I try to run ssh-keygen

# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/mnt/HD_a2/Anonymous_ftp/.ssh/id_rsa):

Could not create directory '/mnt/HD_a2/Anonymous_ftp/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
open /mnt/HD_a2/Anonymous_ftp/.ssh/id_rsa failed: No such file or directory.
Saving the key failed: /mnt/HD_a2/Anonymous_ftp/.ssh/id_rsa.

did your telnet (double echo) caused you any problem when you try to fdisk?
i would think double echo is just a visual thing and should not affect...

it changes the terminal emulation, try both (1 by 1) and see if they get rid of your double echo
