hi, noted the changelog: Date: Tue Nov 29 12:15:52 2011 +0100 Clean up regex code Convert it to use pairmake_xlat, which is better. Better ifdef's for regex support. boot-time check for invalid regular expressions and yes, when i went to run our local GIT version I get this.. /etc/raddb/attrs[128]: Parse error (reply) for entry company.co.uk: No regular expression found in Tunnel-Private-Group-Id Errors reading /etc/raddb/attrs /etc/raddb/modules/attr_filter[12]: Instantiation failed for module "attr_filter.post-proxy" ERROR: Cannot find a configuration entry for module "attr_filter". /etc/raddb/sites-enabled/default[692]: Failed to find "attr_filter.post-proxy" in the "modules" section. /etc/raddb/sites-enabled/default[681]: Errors parsing post-proxy section. the /etc/raddb/attr entry has the following: company.co.uk Service-Type == Framed-User, Service-Type == Login-User, Login-Service == Telnet, Login-Service == Rlogin, Login-Service == TCP-Clear, Login-TCP-Port <= 65536, Framed-IP-Address == 255.255.255.254, Framed-IP-Netmask == 255.255.255.255, Framed-Protocol == PPP, Framed-Protocol == SLIP, Framed-Compression == Van-Jacobson-TCP-IP, Framed-MTU >= 576, Framed-Filter-ID =* ANY, Reply-Message =* ANY, Proxy-State =* ANY, EAP-Message =* ANY, MS-MPPE-Recv-Key =* ANY, MS-MPPE-Send-Key =* ANY, MS-CHAP-MPPE-Keys =* ANY, State =* ANY, Session-Timeout <= 28800, Idle-Timeout <= 600, Tunnel-Medium-Type == IEEE-802, Tunnel-Type == VLAN, Tunnel-Private-Group-Id =~ liss-, Message-Authenticator =* ANY, Calling-Station-Id =* ANY, Called-Station-Id =* ANY, Port-Limit <= 2 I'm guessing the "Tunnel-Private-Group-Id =~ liss-," isnt right in some way - its always worked before though... alan
