unable to send packet using tcpreplay

0

Hi, We are finding difficult to replay a pcapng trace using tcp replay. Here is the error message we are seeing.

Unable to send packet: Error with PF_PACKET send() : Message too long (errno =90) Warning in send_packets.c:send_packets() line 180:

Would like to know whether this is wireshark issue or tcp replay issue.

Thanks for any help,

Would like to know whether this is wireshark issue or tcp replay issue.

could be one of the following

  • libpacp on your system does not support pcpap-ng (please check libpcap version)
  • your pcap-ng file is somehow damaged (please check by opening the file with Wireshark)
  • If your OS is MAC OS X < 1.5.0, you could have hit a known bug (see the tcprelay FAQ)

So, please add some details about your system:

  • OS and OS version
  • Wireshark version on that system
  • tcprelay version
  • libpcap version

Regards
Kurt

Easiest advice: convert your pcapng file to pcap and try again...

hi, i had the same issue, after setting the MTU of interface, i fix it. you could try it for using command ifconfig to set the MTU. "Unable to send packet: Error with PF_PACKET send() : Message too long (errno =90) Warning in send_packets.c:send_packets() line 180"

I have the same issue, recording on a windows 10 machine on an interface with 1500 MTU, JumboFrame disabled, trying to play on debian with 1500 mtu - and got this error: Message too long (errno = 90)

hi, you can make mtu larger to fix this issue. for example, set mtu 3000.

Opened a Tcpreplay issue to track. Will investigate as part of 4.0.5 release.
