  • Hello

    Anyone know the shell command for creating a new user in a specified group via shell?
    I would like to create VPN-users with scripts.

    Thank you

    Ok, i found another solution, ignore my posting [:)]

    Hello, 

     

    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 ? 

    Thank you,

    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

    Cheers -Bob

    Hey Bob, 

    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. 

     

    Thanks,

    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.

    Cheers - Bob
