Seems to supply most of what you want. Furthermore, it implements most of its code in shell code, and allows you to add hooks in the end. Also have a look at the part where it pings the dhcp server if it doesn't get a reply. This seems like an obvious point to tweak the dhcp script. Try to see if you camn use 'dhclient' instead of 'dhcpcd' (they are not the same, right?) -- Tzafrir Cohen /"\ mailto:[EMAIL PROTECTED] \ / ASCII Ribbon Campaign Taub 229, 972-4-829-3942, X Against HTML Mail http://www.technion.ac.il/~tzafrir / \ ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
