Dear Sir/Madam,
Hello， I‘am a Chinese student， now I studying Linux audit and having some
problems. I want to collect some information from network，such as the
accessor’s IP and port. I defined a audit rule in machine A as follow， then
I used “ping” and “vsftpd” programs to test audit. For example, I run "ping
A" in another machine, I can't collect any information in A's audit log. In
addition, I run "ssh A" , then I get some incomprehensible records that
display in the picture below(eg saddr=inet6 host:::1 serv:45983 and
saddr=inet6 host:::ffff:127.0.0.1 serv:41573).
-a always,exit -F arch=b64 -S connect -S getsockname -S getpeername
I am not sure of your intent (inbound vs outbound info). If you want to
collect inbound information, you need to monitor syscalls for inbound events
such as accept, accept4, recv, recvfrom. Ping uses ICMP packets and is not
likely to show up in normal syscalls. You might find them by placing audit
rules in the iptables rules.
