Re: Setup for the IDS-4210 Sensor

It sounds like the default permissions/ownership of the IDS files has been altered. If you have another Sensor that is operating correctly, you might examine the ownership/permissions on the working Sensor (everything in the /usr/nr directory) and make the appropriate modifications on the Sensor that you are having problems with. This will be rather tedious and error prone. A more sure fire way of resolving the problem would be to re-image the Sensor.

Re: Setup for the IDS-4210 Sensor

However, we have not got the recoverary CD.

So, only we can do is try to overcome this problem.

In our campus only have this sensor, moreover, all the tutors are don't know how to set up the IDS.

I want to ask is that related to the TFTP server?

The sensor always said:

Communications Infrastructure

Making sure the IDS daemons are stopped before creating the configuration


Creating configuration files...

cp: cannot create /usr/nr/etc/eventd.conf: Read-only file system

ERROR: Could not create /usr/nr/etc/eventd.conf


It seems related to the file system, isn't it?
