What I do is run virtual interfaces on one box, and run multiple instances of atftpd inside xinetd, each one bound to a different IP and a different root directory. Thus, my file structure looks like this - <br><br>/home/phones/<br>
/home/phones/cisco/<br>/home/phones/cisco/7960 (root directory for one of the atftpd instances)<br>/home/phones/cisco/7961 (root directory for another atftpd instance)<br><br>Then, with a little dhcpd.conf magic, you can easily point different sets of phones to different tftp servers, using pools that match on key Product ID (I think) strings.<br>

How about adding an option to atftpd to enable "check the execute bit" on<br>
the requested file. If the file has the execute bit, set the MAC, IP<br>
Address, etc. as environment variables, exec the file, and return the<br>
output to the requester?<br>
<br>
Then, you could write (for example) spa841.cfg as a shell script which<br>
have access to the MAC, etc. and could run sed/replace/preprocessor/m4 and<br>
create the "file" on the fly.<br>
