Hi to All.I'm opening this thread so any of you which happens to run into useful Shell commands, can add it in here.My goal is to create a document with many Astaro useful shell commands.You are welcome to add, remark or reject any of the commands in here.
In reply to SIKN:
This is my first post, sorry if it is obvious or common sense. But I searched for an answer to my question and I am yet to find a decent answer.
I am trying to find a shell command to list all active IPs on the network. I tried the "/usr/local/bin/count_active_ip.plx --showcount" and it continues to list the IP of my phone even after turning off my phone's WiFi.
I also tried "arp -a" but it also returned the same IP regardless of the face that the phone is no longer on the network.
My question is, Is there a way to list only currently connected devices using a shell command ?

Hi Nlaym and welcome to the UTM Community!
You can get the list of active connections for a 10.1.1.0/24 subnet with:
conntrack -L conntrack|grep 'src=10\.1\.1\.'|grep -oP 'src=.*? dst'|sort -n|uniq -c|sort -n
In reply to BAlfson:
Thank you for the quick and informative reply. Totally appreciated!
I tried the command and I still saw my phone's IP even after leaving the network for almost an hour. I admit that by that time I didn't continue to look for it.
My guess is that --please correct me if I am wrong-- that new connections and traffic has to happen for my phone's IP to disappear from that active connections list, right ?
I must apologize for all the trouble, I am looking for a way to tell when an IP disconnects from the network using shell commands.
If you do cc get packetfilter timeouts you will see that the problem is ip_conntrack_tcp_timeout_established which is probably set to 86400 or one day. The minimum value for this is 7440, 2 hours and 4 minutes. To make that setting, do:
cc set packetfilter timeouts ip_conntrack_tcp_timeout_established 7440
Short of pinging a specific IP, I don't think there's an easy way to get an answer for something that disconnected less than 2 hours before.

Much thanks to BAlfson you saved my day! <3
