Here is what I know so far....

First, the PuTTY connection did things correctly. There you are logged in as as a real user. You have pty assigned so you can run tty type programs like vi. The login process also gave you a shell of -ksh. The leading minus sign tells the shell to run your login scripts. And somewhere in your login scripts (probably either .profile or .env) is an alias changing df to df -k.

Your wodSSH connection is a mess. No login scripts were run (explaining the difference you see with df). You're right that you can just
type:
alias df="df -k"
to fix that. And you can tidy up any other aliases or envirornment problems as well. But there is no reasonable way for you to allocate a pty for yourself. That is terrible... you can't run any full screen editors or other full screen programs. You're going to want to fix that.

Redhat reports df in k as a default...no need for your login scripts to succeed. But you may not have a pty when you connect to redhat via wodSSH.

wodSSH could have one of several possible problems. Neither of us knows your system well enough to tell which it is.

It would be sweet if you have the same problem with Redhat since I do know that well enough to track this down (well, maybe). So try to connect to Redhat from wodSSH and type "tty" If you get the message, "not a tty", then your connection to redhat is screwed up too. If so type:
ps -fp $PPID
and post the results of that. What we need to find out is the name of the parent of your shell. It might be sshd or it might be something else. Or if anyone you know can help you find out the name of the parent of your shell on OpenBSD that would work too.

I can only think of two ways for this happen, and the name of the parent will tell me which it is.

chsh

CHSH(1)                                                            User Commands                                                           CHSH(1)

NAME

       chsh - change login shell

SYNOPSIS

       chsh [options] [LOGIN]

DESCRIPTION

       The chsh command changes the user login shell. This determines the name of the user's initial login command. A normal user may only change
       the login shell for her own account; the superuser may change the login shell for any account.

OPTIONS

       The options which apply to the chsh command are:

       -h, --help
           Display help message and exit.

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory.

       -s, --shell SHELL
           The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.

       If the -s option is not selected, chsh operates in an interactive fashion, prompting the user with the current login shell. Enter the new
       value to change the shell, or leave the line blank to use the current one. The current shell is displayed between a pair of [ ] marks.

NOTE

       The only restriction placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the superuser,
       and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh
       in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell
       back to its original value.

FILES

       /etc/passwd
           User account information.

       /etc/shells
           List of valid login shells.

       /etc/login.defs
           Shadow password suite configuration.
