tcpdump pcap_loop eroor

Question

Hi When i use tcpdump along with Gulp I get an error

tcpdump: pcap_loop: error reading dump file: Interrupted system call

The code I used is

 ./gulp  -i eth1 -r 1024  -p 10 | taskset -c 2 tcpdump -r- -C 2 -W 5 -Z root -w /share/capture/job.pcap

Could you please help me with this??

Answer 1

I don't think that taskset will pass STDIN to tcpdump. Please try your command without taskset.

./gulp -i eth1 -r 1024 -p 10 | tcpdump -r- -C 2 -W 5 -Z root -w /share/capture/job.pcap
