Hi there,
I’ve created an script for Solaris and Opensolaris to monitor all outgoing TCP
and UDP connections by process, user and port.
It has some filtering capabilities allowing to filter traffic by port, process
or user.
It's slightly similar to Brendan's DTT/Net/connections but I've included the
monitoring of all outgoing connections and filtering capabilities.
Here are some examples:
Usage:
# ./conntrack -h
USAGE: ./conntrack [-h] [-p port] [-c command] [-u user]
-p port # filter by port (incompatible with user and command)
-c command # filter by command (incompatible with port and user)
-u user # filter by user (incompatible with port and command)
eg,
./conntrack -p 22 # snoop connections to port 22
- What process is listening on port 23?:
# ./conntrack -p 23
