[SOLVED] Problem for users under Tacacs+ server on redhat

tonmoy · 04-18-2013, 12:54 AM

For research/study purpose I have deployed Tacacs+ server on redhat 6 and connected CISCO 7200 Routers with it using GNS3 emulator. Primary everything is working fine. I can add user in Tacacs+ config file, can define user priv-lvl, can restrict users on different commands specified on the config file. The problem I am facing is that (1) I can't assign user based enable password/secret on Tacacas+ Server and (2) the user authentication works for both telnet and console sessions but the authorization only works for telnet sessions where I need console users also to be authorized on commands. Besides, (3) I am looking for any web based Tacacs+ accounting system by which I can see the Tacacs+ real time logs in an interactive web interface. I have used a script and can view the logs in html file but this can't fulfill my requirements. Please help me to figure out my situation. Thanks in advance for trying for me.

### I can't use [line: 18] "enable = cleartext hello123" on Tacacs+ config file. Although many web tutorials show me to do that. Anyway, the error I get with "tac_plus -P -C /etc/tacacs/tac_plus.cfg" command is:
