| |
| @command{vtysh} is integrated shell of Zebra software. |
| |
| To use vtysh please specify ---enable-vtysh to configure script. To use |
| PAM for authentication use ---with-libpam option to configure script. |
| |
| vtysh only searches @value{INSTALL_PREFIX_ETC} path for vtysh.conf which |
| is the vtysh configuration file. Vtysh does not search current |
| directory for configuration file because the file includes user |
| authentication settings. |
| |
| Currently, vtysh.conf has only one command. |
| |
| @example |
| ! |
| username foo nopassword |
| ! |
| @end example |
| |
| With this set, user foo does not need password authentication for user vtysh. |
| With PAM vtysh uses PAM authentication mechanism. |
| |
| If vtysh is compiled without PAM authentication, every user can use vtysh |
| without authentication. |
