tcpdump: pcap_loop: Error: Interface packet capture bus

Hi,

 

I'm not able to run tcpdump, when I type in:

 

tcpdump -s0 -ni 1.2 host x.x.x.x

 

it stops automatically:

 

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on 1.2, link-type EN10MB (Ethernet), capture size 65535 bytes tcpdump: pcap_loop: Error: Interface packet capture busy 0 packets captured 0 packets received by filter 0 packets dropped by kernel

 

And the error: tcpdump: pcap_loop: Error: Interface packet capture busy is shown.

 

Any idea how to solve this ?

 

Thanks !

 

Kind regards, Frederik
