Dhcpd Bizarre!!!!!!!!!!!!!!!!
Hi all, I am using dhcpd on openBSD. I wanted to make a log file of my own from which enteries will never vanish. Though I can use dhcpd.leases and parse it to get the values but i wanted to it from the sourse itself. What i have done so far -> I have made changes in db.c 1. in function db_startup() 2.write_lease(struct lease *lease) I am attaching db.c file with changes with it. wherever u find "FILE *abc or int pqr".i have added those lines it is compiling allright but is not writing into the file. Plz Help some one.. Rahul [demime 1.01d removed an attachment of type text/x-csrc which had a name of db.c]
