Hi, I have noticed a strange behaviour, I have line log configured to do logging at various steps. In one of the steps i print the username in logs. Now when the username is non english font(any other language viz hindi, arabic, russian, chinese tested with these) it crashes the freeradius application. Debug log is as follows 124456) Received Access-Request Id 164 from 10.198.64.10:54713 to 10.40.125.30:1812 length 319 (124456) User-Name = " रहलहवकह" (124456) Chargeable-User-Identity = 0x0a (124456) Location-Capable = Civix-Location (124456) Calling-Station-Id = "xxxxx" (124456) Called-Station-Id = "xxxx" (124456) NAS-Port = 8 (124456) Cisco-AVPair = "audit-session-id=0a40c60a000653d3eee5ec57" (124456) Acct-Session-Id = "57ece5ee/xxxxx/329431" (124456) NAS-IP-Address = xxxxx (124456) NAS-IPv6-Address = 2001::2001 (124456) NAS-Identifier = "xxxxxx" (124456) Airespace-Wlan-Id = 34 (124456) Service-Type = Framed-User (124456) Framed-MTU = 1300 (124456) NAS-Port-Type = Wireless-802.11 (124456) Tunnel-Type:0 = VLAN (124456) Tunnel-Medium-Type:0 = IEEE-802 (124456) Tunnel-Private-Group-Id:0 = "807" (124456) EAP-Message = 0x0201001b0120e0a4b0e0a4b9e0a4b2e0a4b9e0a4b5e0a495e0a4b9 (124456) Message-Authenticator = 0xf478d56d8c1d498752fbd782302cf884 (124456) # Executing section authorize from file /usr/local/etc/raddb/sites-enabled/default (124456) authorize { (124456) if (!&session-state:unique-session-id) { (124456) if (!&session-state:unique-session-id) -> TRUE (124456) if (!&session-state:unique-session-id) { (124456) update { (124456) Executing: /usr/bin/shuf -n 1 -i 0-99999: (124456) Program returned code (0) and output '42345' (124456) EXPAND %{exec: /usr/bin/shuf -n 1 -i 0-99999} (124456) --> 42345 (124456) &session-state:unique-session-id = 42345 (124456) } # update = noop (124456) } # if (!&session-state:unique-session-id) = noop (124456) policy filter_username { (124456) update control { (124456) linelogvar := "request_attrs" (124456) } # update control = noop (124456) linelog: EXPAND messages.%{%{control:linelogvar}:-default} (124456) linelog: --> messages.request_attrs linelog module config reference = "messages.%{%{control:linelogvar}:-default}" messages { request_attrs = "%{User-Name},%{Calling-Station-Id},%{Called-Station-Id},%{NAS-Port},%{Acct-Session-Id},%{NAS-IP-Address},%{NAS-Identifier},%{Airespace-Wlan-Id},%{Service-Type},%{Framed-MTU},%{NAS-Port-Type},%{Tunnel-Type:0},%{Tunnel-Medium-Type:0},%{Tunnel-Private-Group-Id:0},%T,%{md5:%{Acct-Session-Id},%{session-state:unique-session-id}},Request:,%{EAP-Type}" } policy filter_username update control { linelogvar := "request_attrs" } linelog Although I have made a workaround of rejecting as well as substituting non english font usernames. This is to make the community aware if it is not already. Also I dont think some of us would like to reject non english username do we?
