Hi All, I am currently configuring power distribution units(PDU) in our organisation, authentication from freeradius-1.0.1-3.RHEL4.3 1. I have configured the dictionary file accordingly. client 131.xxx.xx.xxx { secret =abcdeffghijk shortname =PDU1 } client 131.xxx.xx.xxx { secret =lmnoopqrstuve shortname =PDU2 } 2. I have also defined the ATTRIBUTE and VALUE the dictionary file as per APC vendor's instructions VENDOR APC 318 BEGIN-VENDOR APC ATTRIBUTE APC-Service-Type 1 integer APC VALUE APC-Service-Type Admin 1 VALUE APC-Service-Type Device 2 VALUE APC-Service-Type ReadOnly 3 3. I have modified the users file , created groups and outlet access for each group. In the below example,I have given group3 access to outlet3. DEFAULT Group == "group3", Auth-Type = System APC-Service-Type = Outlet, APC-Outlets = "3", Fall-Through = No 4. Now, I have 20 PDUs setup (in pair) and I also would like to restrict the subnets that it can authenticate from. I would like to set up a rule in user file as following: If pdu1 or pdu2 {if group1 and authenticated from the approved subnets Then APC-Service-Type = Outlet, APC-Outlets = "1", } ....And so on for the rest of PDU pairs. Has anyone done a similar setup before? If so, could you please shed light? Thanks in advance Uma u.palvannan@qut.edu.au
