Hi experts, I got a problem when using freeradius for authentication network staff to login the network device. we have two type of devices, 3com and cisco, they are have difference VSA,at the same time, the network staff are divided into two group: admin and monitor, the admin have the read/write privilige, the monitor should only have read privilige.So I use such users file: /etc/freeradius/users DEFAULT Auth-Type := System, Group == "admin", Huntgroup-Name == "cisco" Service-Type = NAS-Prompt-User, Cisco-AVPair = "shell:priv-lvl=15", Login-Service = Telnet DEFAULT Auth-Type := System, Group == "monitor", Huntgroup-Name == "cisco" Service-Type = NAS-Prompt-User, Cisco-AVPair = "shell:priv-lvl=1", Login-Service = Telnet DEFAULT Auth-Type := System, Group == "admin", Huntgroup-Name == "3com" Login-Service = Telnet, 3Com-User-Access-Level = 3 DEFAULT Auth-Type := System, Group == "monitor", huntgroup-Name == "3com" Login-Service = Telnet, 3Com-User-Access-Level = 1 and create 4 accounts within debian linux, for example, aaa, bbb, ccc, ddd. aaa and bbb are member of admin group, ccc and ddd are member of monitor group, debian sarge linux group info /etc/group(debian linux) admin:x:1001:aaa,bbb monitor:x:1010:ccc,ddd the /etc/huntgroup: cisco NAS-IP-Address == 192.168.1.1 cisco NAS-IP-Address == 192.168.1.2 cisco NAS-IP-Address == 192.168.1.3 3com NAS-IP-Address == 192.168.1.4 3com NAS-IP-Address == 192.168.1.5 3com NAS-IP-Address == 192.168.1.6 this kind of configuration work just fine. and now, I would like to use mysql for user db backend. So I got two problem. 1. could mysql utilize the huntgroup file? 2. how to transfer this user info , group check and group reply info into mysql? -- He is nothing -- He is nothing
