项目描述: Env_audit is a program that ferrets out everything it can about the environment. It looks for

pppd has several opportunities for shelling out.

From command line:
1) pppd can call a script to initialize a device. To audit this aspect type
this:

pppd /dev/modem init full_path/env_audit

2) pppd can also run a script to perform the connection in place of chat. 
To audit this aspect, type the following:

pppd /dev/modem connect full_path/env_audit

From ifup-ppp script:
3) pppd can also call a script to perform the disconnection if a session is 
established. ( ifdown ppp0 ). To perform this audit, you will need to edit the
/etc/sysconfig/network-scripts/ifup-ppp file. At the very end of the script,
you will find: exec pppd ...  Just add: 

disconnect full_path/env_audit

to the pppd execution command. To trigger the audit, do a 'ifup ppp0' and then
a 'ifdown ppp0'.

4) pppd can also run a welcome script after ifup ppp0 has been exec'd. To 
audit this, go to the very end of the ifup-ppp script, and add this:

welcome full_path/env_audit

To trigger the audit, just do a 'ifup ppp0'.

5) And finally, pppd can use an external program rather than a specific 
terminal device to communicate. To audit this, you will need to go to the end
of the ifup-ppp script and add:

pty full_path/env_audit

To trigger the audit, just do a 'ifup ppp0'.

The results of all these audits will be placed into /tmp/env_audit.log. You
will also want to do these audits one at a time to avoid over-writing results.
