Is the client sending accounting packets?
Yes, the client send the account packets.
What's "radcheck" ?
Sorry, the correct command is checkrad.
Can the user log in once?
Yes, all users can log in 3 times, as we configured in the WLC Cisco, but we want to restrict one group in 2 connections.
After the user logs in, does the client send an accounting "start" packet?
We suppose. The log detail shows: Mon Jun 8 15:12:29 2015 User-Name = "test" NAS-Port = 29 NAS-IP-Address = 158.251.4.193 Framed-IP-Address = 158.251.211.7 NAS-Identifier = "wlc.ucv.cl" Airespace-Wlan-Id = 4 Acct-Session-Id = "5575db47/00:17:9a:b0:26:ae/1269" Acct-Authentic = RADIUS Tunnel-Type:0 = VLAN Tunnel-Medium-Type:0 = IEEE-802 Tunnel-Private-Group-Id:0 = "226" Acct-Status-Type = Start Calling-Station-Id = "158.251.211.7" Called-Station-Id = "158.251.4.193" Acct-Unique-Session-Id = "7a2d24188796cc40" Timestamp = 1433787149 Mon Jun 8 15:12:41 2015 User-Name = "test" NAS-Port = 29 NAS-IP-Address = 158.251.4.193 Framed-IP-Address = 158.251.211.7 NAS-Identifier = "wlc.ucv.cl" Airespace-Wlan-Id = 4 Acct-Session-Id = "5575db47/00:17:9a:b0:26:ae/1269" Acct-Authentic = RADIUS Tunnel-Type:0 = VLAN Tunnel-Medium-Type:0 = IEEE-802 Tunnel-Private-Group-Id:0 = "226" Acct-Status-Type = Stop Acct-Input-Octets = 76060022 Acct-Output-Octets = 1508183842 Acct-Input-Packets = 773252 Acct-Output-Packets = 1227539 Acct-Terminate-Cause = User-Request Acct-Session-Time = 12 Acct-Delay-Time = 0 Calling-Station-Id = "158.251.211.7" Called-Station-Id = "158.251.4.193" Acct-Unique-Session-Id = "7a2d24188796cc40" Timestamp = 1433787161
Is that packet stored in a DB (radutmp, sql, etc.)
Yes, the packet is stored in radutmp, but only the last connection. Thats mean that appears only one input.
When the user logs in a second time, do they get Simultaneous-Use set for them?
No, doesn't work. User can connected multiple times. In debug mode doesn't appear any related with Simultaneous-Use or something like that.
Does the server discover that the user is already logged in?
We think no, because doesn't work.
What happens then?
We don't know for what reason does not work.
The debug output, as suggested in the FAQ, "man" page, web pages, and daily on this list?
The debug doesn't show any error or warning. Thank in advance for your help. We really appreciate it. Kind regards Felipe López P.
