weird linux cursor problem. I'm having this problem with an ssh terminal where the cursor won't advance past the last character in a line, so I can't change or delete the last character.

This is thoroughly annoying, but Google searches are not helping me. In otherwords, say i want to alter a previous command. I hit the up arrow and it brings up that command, but then I can't change the last character as the cursor just stops there.
Is this a local setting or something? I am using SSH Tectia client and Debian Linux.
I can't figure out what is causing this or what changed.

you may be using vi history. try [esc] - a - foo.

Yeah, I have that problem too. I just copy and paste.

What is your $SHELL on the remote host?
What is $TERM set to? What terminal type is Tectia set to?
What is the output from an "stty -a"?

echo $SHELL = /bin/bash
echo $TERM = vt100

are you escaping to get into the buffer?

also, if you are doing an insert you wont be able to get past that character - try an append instead

Try swapping between "set -o vi" and "set -o emacs". Do either of those give you the functionality you were used to?

set -o emacs works.

in case anyone else has this problem, I fixed it permemently on this machine by editing $HOME/.bash_profile and putting in that line "set -o emacs". Man was that driving me crazy.

There is a sequence of keys that can put you in vi mode at the bash prompt. While I don't remember it off the top of my head, beware of it - even with that setting in your .bash_profile, you can still accidently end up in vi mode.

Wait a second! I want to know how to get into vi mode.
