see traffic from a specific IP

systat -ifstat gives me input, output, total, and averages which is good. What I want to know is the following.

I connected to my FreeBSD server from a friends house using WinSCP to download a tar (rather large file 6.5 GB) and I want to check the transmission status.

When I'm ssh'd into my server is there a command that will show traffic to specific IPs?
 
Hi,

There is many ways to achive similar results.

pftop
Please consider to install it firstly before you start using it from sysutils/pftop, and accordingly you have to enable PF in /etc/rc.conf

Another way would be to see a whole traffic, so sniffing is a good idea
[CMD="tcpdump"] -e -nnn -i <INTERFACE> src <SRC IP>[/CMD]
or you can use it to see traffic for specific destination ip on your server
[CMD="tcpdump"] -e -nnn -i <INTERFACE> dst <SRC IP>[/CMD]

You can check also below ports, maybe something match to your needs
net/ntop
net-mgmt/iftop


Does that match to what are you expecting ?
 
kr651129's question is straight forward, and I was having the same question a few days ago, but all programs I've tried did not do the job:

Is there a utility that shows in/Kbps, out/Kbps for a specific ip? Not the number of states when using pf(4), nor something identical.
