I'm just starting to play around with the kernel. I want to know how most people do things like print out info and/or write to a file. I'm interested in playing with network code and wanted to print some parts of the skb's. for instance my first thing I tried to do is to print the destination address of all icmp ECHO_REPLY packets but haven't been able to get this to work. Any tutorials on this? thanks! -kirk -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
