How to show the active connection to a specific host

andy_currigan — Thu, 14 Mar 2019 16:26:45 GMT

I need to list the active connection to a specific hosts.

I try to take a look on sk65133 but it's a little bit confusing.

someone can post the cli sintax to list all the connection to or from a specific ip address on a gaia gateway?

fw monitor -e "host(x.y.z.w) and host(a.b.c.d), accept;"

🙂

or

fwaccel conns | grep 192.168.1.1

or ...

tcpdump -nni any host a.b.c.d

with fwaccel conns I get the following output

192.168.41.30 55359 172.16.168.14 443 6 ...A...S...... 1/5 5/1 0 0

How can I get the session time out?

grep this with netstat -ni | grep 192.168.41.30 - and see TTL status (ESTAB/WAITING etc.). make a ping to that host then and try again, you'll see a difference 🙂

hi jerry,

I ping 8.8.8.8 from 192.168.1.166 and I run the command but I get the interface table not the sessions
