Duplicate pings? and sash?

Hi Everybody,
I am trying to set up RH9 on a PC that will be on a private wireless network, running the Asterisk PBX software.
Initial install was on my home network that has internet access (to download Asterisk), IP Everything went smooth and easy, I can also log in from other PC's with SSH (using putty) as root with no problems.
BUT, when I change to IP of eth0 to (with netconfig), I find that when I try to log in remotly with SSH, I get a sash command shell and not the initial command line interface (bash, I think). I have searched with Google to try and find what is going on to no avail. Can someone here help me?
Another problem is that when I try to ping machines on the wireless network, I am getting duplicate replies. This seems to cause the pinged machines problems. I access the wireless network with an Access Point in client mode. Any ideas on this? I hope these questions aren't too stupid.

Stupid. No. Wierd Yes.

Just by changing your ip you shouldn't get a different shell. You can cat /etc/passwd to see if sash is defined as a shell for any of your users.

Do you have 2 nics on this machine and are they both configured on the same network on a hub? You really need to look at your network and see why this is happening. You can run ethereal or tcpdump on all machines to see where this is coming from.

I thought I had better follow up on my original post and let people know what I found...
The sash shell was from another user who put up a Linux node on the IP address that I wanted. I should have known about it. Oh well....
And the weird duplicate pings were caused by my D-Link DWL-900AP+ client mode access point. If I tried to connect faster than 2 Mbs to the community access point, all hell broke loose. I just didn't see it with Windows. I used Ethereal on a laptop and confirmed that the duplicate packets were there with all my machines and not just the new linux one.
So a quick config change on the AP fixed that problem.
Many thanks to all here for your patience.
