During installation I have choosen the medium firewall setting, set my NIS
domain and clicked on Use Broadcast to find NIS server. When the installed
system starts up it can't find a NIS server due to the default blocking
rules in the firewall setting
Steps to Reproduce:
1. Medium Firewall setting
2. Use broadcast to find NIS server
Yes. It's really not feasible to let RPC-based services through the firewall.
I agree with your statement but when the firewall is setup this way you should
not be able to select NIS or you should get a short message telling you the
We've hit this bug internally a couple times with AS 2.1 ia64.
In fact, if you combine the two together, you run in to a bug I filed under
97710 where a user can't log in even as root in multi-user if NIS is set to
broadcast binding and the default firewall is set up.
I respectfully ask that someone take another look and re-consider. I suggest
making it so "broadcast" isn't an available option when medium or high
firewall is selected and apply this to the next Enterprise Linux and Linux
I'm not sure what the protocol here is so I won't re-open this moment in case
that's considered rude. Thanks.
