2.9.14 packet sniffer

RouterOS General
1

Anyone else having major issues with Packet Sniffer in 2.9.14? It seems as thought its not capturing all packets and other oddities. 20-30 entries show up and then disappear. After moving the pcap to ethereal I see that it only captured about 10% of the traffic. Just curious if anyone else noticed this.

I also notice when filtering on specifics you still get ICMP and non-IP from everywhere included in the pcap.

i’m having a similar issue here. It’s starting, and then dying. I created a script, below, that restarts it every 5 minutes in case it’s not running, since I’m running snort on my server that it is supposed to be streaming to. Anyways, every 5 it runs, it logs that the sniffer is not running. It used to stay up all the time in 2.9.13 before I upgraded…

Anyone else seeing similar ???

restart script:

:if ( ! [tool sniffer get running] ) do={:log  info "Sniffer IS NOT RUNNING at Start of script"
/tool sniffer stop
:delay 2s
/tool sniffer start} else={:log  info "Sniffer is running at Start of script"}

:if ( [tool sniffer get running] ) do={:log  info "Sniffer is running at End of script"} else={:log  info "Sniffer IS NOT RUNNING at End of script"}

and a snippet of my syslog:

Mar 18 19:36:00 sentry script,info Sniffer IS NOT RUNNING at Start of script
Mar 18 19:36:02 sentry script,info Sniffer is running at End of script
Mar 18 19:41:00 sentry script,info Sniffer IS NOT RUNNING at Start of script
Mar 18 19:41:02 sentry script,info Sniffer is running at End of script
Mar 18 19:46:00 sentry script,info Sniffer IS NOT RUNNING at Start of script
Mar 18 19:46:02 sentry script,info Sniffer is running at End of script
Mar 18 19:51:00 sentry script,info Sniffer IS NOT RUNNING at Start of script
Mar 18 19:51:02 sentry script,info Sniffer is running at End of script
Mar 18 19:56:00 sentry script,info Sniffer IS NOT RUNNING at Start of script
Mar 18 19:56:02 sentry script,info Sniffer is running at End of script

You should upgrade to the latest version to fix this issue.

i’m already on 2.9.17, and it’s doing it there. 2.9.13 was fine…

5

I meant 2.9.18 when it becomes available :wink:

6

… just need to make sure MikroTik knows it’s a problem, since it was something that was broken along the way, they need to know it’s now broken so that it can be fixed…

I meant 2.9.18 when it becomes available

Which will be soon I suppose (given that it already is on the demo systems)?

ok, so now that i’ve upgraded to 2.9.18, the Sniffer starts as it should, and stays started. Yeay !

ok, now I have a problem that the CPU load shoots up to 55 and stays there. This didn’t happen in previous versions.

Here’s my sniffer config:

> /tool sniffer print
          interface: int_if
       only-headers: no
       memory-limit: 0
          file-name: ""
         file-limit: 0
  streaming-enabled: yes
   streaming-server: 192.168.200.3
      filter-stream: yes
    filter-protocol: ip-only
    filter-address1: 0.0.0.0/0:0-65535
    filter-address2: 0.0.0.0/0:0-65535
            running: yes
