Helli List, I am working on a kernel module and netfilters. from this kernel module i want to send icmp port unreachable packet a host. i have the skbuff of the original SYN packet. i am unable to figure out how to move ahead in this direction. i tried icmp_send() but this dint worked. Secondly, i want to log some data. but not to /var/log/messages but to a different file. can i do it with some API from Kernel. currently i am using user_modehelper(). with a userspace program coded for thios perticular logging as argument. but the kernel hangs whn it reaches this call so no logging is taking place any ideas any help would be invauable thx a lot in advance. __________________________________ Do you Yahoo!?
