You got this message because you are probably running udev on your system. If you are not, or you feel that you have reached this message in error you can send me an email (look to bottom of file for address). If you're running udev on your system, you were probably directed to read this file during build. For udevd (the daemon responsible for creation/deletion of device nodes), you will need to add the following lines to your udev rules (ie, /etc/udev/rules.d/50-udev.rules):. # Section for zaptel device KERNEL="zapctl", NAME="zap/ctl" KERNEL="zaptimer", NAME="zap/timer" KERNEL="zapchannel", NAME="zap/channel" KERNEL="zappseudo", NAME="zap/pseudo" KERNEL="zap[0-9]*", NAME="zap/%n" This will take care of making all the automagic occur that needs to be done so that udevd will make the right files for zaptel. And, You may wish to add these permissions to your permissions file (ie /etc/udev/permissions.d/50-udev.permissions), as some have found that the ctl device is inaccessible without the following: # zaptel devices -- for running asterisk as root zap/*:root:root:05700 # zaptel devices -- if you want to run asterisk as a different user # (asterisk in this case) zap/*:asterisk:asterisk:660 Matthew Fredrickson creslin@NOSPAMdigium.com
