Hi, I'm trying to do an account-logon to a cisco ISG (aka NAS). I've created a file to carry the attributes. The file looks like this.. User-Name += "jane" Service-Type = Outbound-User cisco-command-code=01 cisco-avpair = "ssg-account-info=S10.174.168.2:294", Here's the command I sent. Radclient x f /home/admin/coa_file 10.172.168.6:3799 coa testing123 The debug from radclient doesn't show any errors. It shows Cisco-Command-Code = "01" Here's the debug from the cisco router.

How do I specify the command code to be hex? (I've tried 0x01 but again it converts the ascii to hex) Also, is there documentation that explains the syntax to be used in the attribute file? Thanks, Steve
