i'm system administrator for a small company and i'm experiencing a strange behaviour on 1 of my 4 IDS 4235 sensor running 4.1.(5)S252 .Two of them are on the external (toward internet) and 2 of them are on the internal network. They are all managed by IDSMC 2.1 and CiscoWorks 2.1. At the moment the one on the inside cannot be reached with IEV with the following errors:
and in fact i did this opearation and it brings to the same behaviour. Thank you all guys for the support.
I'll probably need to upgrade my sensor to the new IPS version, but this is dependant to my old VMS version 2.2 and OS machine with windows 2000. So as far as i know i should upgrade windows 2000 to 2003 and then update VMS to the lastest version and then upgrade sensors to be imported with 5.x version to the new VMS version(2.3?)Is that correct?
