Astaro useful shell commands.

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

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.

Hi, 

Can some one tell me the shell command to view SMTP Quarantine.

Hi Irun,

ls -R /var/chroot-smtp/spool/quarantine/0

What do you want to do with that information?  Mail Manager is very quick and easy after you spend a little time with it.

Hi,

I am looking for a solution not to only live monitor the traffic of a special client with iftop like

iftop -i eth3 -f "src host 192.168.1.182"

but to write this output into a file for later analysis.

Unfortunately the iftop version on UTM 9.6 is 0.17 and therefore rather outdated and does not support "-t"-option. 
Since iftop-1.0pre3 (2014-01-01), a text output mode was added. This will be very useful to anyone trying to parse the output of iftop.

Is there any way to implement a newer version of "iftop" on UTM 9.6?
