[Samba] preexec, logging, and my problem

[Jack Mendez]

okay so after trying a bit to understand how all of this works i think i 
need a bit more support.
>thanks to joel, my problem where users can log on multiple times looks 
>like it has a solution.
>to prevent this, he outlined a process by which one can monitor the 
>process IDs of samba users, then user smbstatus grep for that user, find 
>the process id, and then do whatever i want with them.
>in this case prevent the second user from logging in.
>now a script was provided which grabs the variables for each samba user i 
>have almost no experience with scripting this complex so i don't really 
>understand it.
>particularly the bits about storing values of some kind.
>there were some concerns about security and how it was set.
>the security setting in my samba config is set to user.
>so, could someone explain this again?
>how does the script which stores variables work, how would one use it to 
>get the appropriate information for my problem?
>how does the information from the dump which the script provides relate to 
>the smbstatus command, and finally i know grep can be used the retreve the 
>appropriate information from the files, once i have it killing the process 
>would just terminate the login? not sure.

>thanks joel for all your help but i am kinda new to this so its a bit 
>overwelming.
