Hi , I am using ulogd to store iptables logs to /tmp/logfile.txt. There is an application ( say X ) running on userspace ( using nfqueue in FORWARD chain in filter table ) to do some kind of blocking packets based on time ( some thing like a minimal parental control feature ). I would also want to generate some logs and put into the same /tmp/logfile.txt file. Since ulogd and X are using same file , we need some file locking mechanism. Is there any other way to forward these message to netlink socket and ulogd can itself handle, so that i dont have to do any kind of synchronization. May be i can put the question in this way: Kernel is sending some message and ulogd listens and receives the message on netlink socket. Could any other application in userspace , send some message to this socket and ulogd can read and write to the log file f ?
