Hello...

I have live servers and testing/training servers on my LAN. I'd
like to ensure I don't inadvertently connect to a live server
when I think I'm connected to a tester/training server and thus
do irreparable damage.

I'd like to prevent connections to specific private ips. Subnets
don't do it since the IPs I'm after are scattered in a range of
IPs.

Any suggestions?

Thx,
D.

Are you using a router? If so, you can deny specific IP addresses access
to the Internet from the configuration interface.

The servers are on the LAN so preventing internet access won't
do it. I'm thinking more along the lines of a hosts file, but
for ip address. Redirect all traffic to a specidifed address to
a null host.

Any other suggestions?

Thx,
D.

I don't have any Windows server operating systems installed right now so
I can't check. On my machine I can set a Hosts Deny which will do
exactly what you want, but that won't help you because this is Linux.
I'm sure Windows servers must have the equivalent. Try posting your
question in one of the servers groups such as:

microsoft.public.windows.server.general

Sorry I wasn't able to help you with this.

I've had a think, and all I can come up with is to use a
software firewall on your PC, and spcifically block that IP address.

The servers are not on the same local subnet as you, by any chance, are
they?

No. Unfortunately they're on a WAN...different subnets.
