<SOLVED>Conky: show inbound and outbound connections

[Fred Barclay]

I'm just getting started with conky, so a lot of this is based on guesswork...
I grabbed a .conkyrc file from a post here and I've been modifying it to my liking. One of the things I want is for it to show my inbound and outbound connections. The original creator already had designed it to show inbound, so I guessed a bit and rewrote a portion to show outbound as well:

Code: Select all

${color #0077ff}Port(s)${alignr}#Connections
${color #0077ff}Inbound: ${color lightgrey}${tcp_portmon 1 32767 count}  ${color #0077ff}Outbound: ${color lightgrey}${tcp_portmon 32768 61000 count}${alignr}${color #0077ff} Total: ${color lightgrey}${tcp_portmon 1 65535 count}

${color #0077ff}Inbound Connection ${alignr} Local Service/Port${color lightgrey}
 ${tcp_portmon 1 32767 rhost 0} ${alignr} ${tcp_portmon 1 32767 lservice 0}
 ${tcp_portmon 1 32767 rhost 1} ${alignr} ${tcp_portmon 1 32767 lservice 1}
 ${tcp_portmon 1 32767 rhost 2} ${alignr} ${tcp_portmon 1 32767 lservice 2}
 ${tcp_portmon 1 32767 rhost 3} ${alignr} ${tcp_portmon 1 32767 lservice 3}
 ${tcp_portmon 1 32767 rhost 4} ${alignr} ${tcp_portmon 1 32767 lservice 4}
 ${tcp_portmon 1 32767 rhost 5} ${alignr} ${tcp_portmon 1 32767 lservice 5}
 ${tcp_portmon 1 32767 rhost 6} ${alignr} ${tcp_portmon 1 32767 lservice 6}
#Outbound?
${color #0077ff}Outbound Connection ${alignr} Local Service/Port${color lightgrey}
 ${tcp_portmon 32768 61000 rhost 0} ${alignr} ${tcp_portmon 1 32767 lservice 0}
 ${tcp_portmon 32768 61000 rhost 1} ${alignr} ${tcp_portmon 1 32767 lservice 1}
 ${tcp_portmon 32768 61000 rhost 2} ${alignr} ${tcp_portmon 1 32767 lservice 2}
 ${tcp_portmon 32768 61000 rhost 3} ${alignr} ${tcp_portmon 1 32767 lservice 3}
 ${tcp_portmon 32768 61000 rhost 4} ${alignr} ${tcp_portmon 1 32767 lservice 4}
 ${tcp_portmon 32768 61000 rhost 5} ${alignr} ${tcp_portmon 1 32767 lservice 5}
 ${tcp_portmon 32768 61000 rhost 6} ${alignr} ${tcp_portmon 1 32767 lservice 6}

My question is: is this correct? Will the code show the outbound connections? It certainly shows something now, but I'm not positive what it is.

(And while we're at it, it keeps on showing an outbound connection to amazonaws. Anyone know what this is? I'm probably going to start a new thread about it once I make sure that it really is an outbound connection rather than a bug in my conky.)

Are you talking about your network inbound and outbound? This may not help but this is how mine works.

Code: Select all

#  network inbound and outbound
${color}Network  Inbound ${color green}${downspeed eth0}
${color}${color green}${downspeedgraph eth0 30,0}
${color}Network Outbound ${color green}${upspeed eth0}
${color}${color green}${upspeedgraph eth0 30,0}

On my system eth0 is for the USB connection on the modem and eth1 is for the Ethernet connection on the modem. (My motherboard lost it's Ethernet connection last month... another story.)

I am not familiar with the code you posted but I am curious about it...

Cheers!

Jim

Thanks Jim. Actually, no, that's not what I'm referring to--although I do already have some code that looks pretty similar. I'm actually trying to monitor how many ports are open/connected, both inbound and outbound, and who they're connected to.

Inbound should be

Code: Select all

 ${tcp_portmon 1 32767 rhost 1} ${alignr} ${tcp_portmon 1 32767 lservice 1}

Outbound is

Code: Select all

 ${tcp_portmon 32768 61000 rhost 1} ${alignr} ${tcp_portmon 32768 61000 rservice 1}

[Fred Barclay]

Thanks, WarfRat. A few questions:
I see that outbound should use rservice instead of lservice. What's the difference?
Also, I noticed that your rhost, reservice, and lservice start with 1 instead of 0. Why is using a 0 wrong?

Thanks! Sorry--I feel like an absolute newbie all over again!

[WharfRat]

The rservice and lservice refer to remote/local service names. Both reference /etc/services so I'm not sure of the difference.

When I start with port 0 the first two lines displayed are duplicates. So I'm not really sure if it should start with 0 or 1

I had to google around some to see how conky aficionados used that variable. It's been years since I've looked at it

This site provides explanations of conky's variables, but sometimes they are lacking. http://conky.sourceforge.net/variables.html

Good luck

[Fred Barclay]

Thanks WarfRat. That link looks promising!

Your code shows outbound perfectly too. Although I still haven't figured out the 0 vs. 1...
