in thread Net::RawIP - invalid checksum ?

Negitive. I now get.. (Defaults to TCP, src/dst ports are now 0) 

14:46:44.553547 IP (tos 0x0, ttl 60, id 35744, offset 0, flags [DF], p
+roto TCP (6), length 40)
    192.168.10.10.0 > 192.168.10.20.0: Flags [DF], cksum 0xcd50 (incor
+rect -> 0xd550), seq 0, win 65535, length 0

If i use your example and just change... 

my $packet = new Net::RawIP({udp => {check => 0}});

[download]

Or even..

my $packet = new Net::RawIP({udp => {}});

I still get a bad checkdum... 

4:47:22.542872 IP (tos 0x0, ttl 60, id 35885, offset 0, flags [DF], pr
+oto UDP (17), length 35)
    192.168.10.10.6544 > 192.168.10.20.514: [bad udp cksum 0xb59d -> 0

    Well. Like I said, I couldn't test it. I was just trying to help with a possible alternative.

    I notice after reading both the docs, and source. There's precious little, regarding the check option.

    OTOH I notice
    Net::RawIP::opt
    and
    Net::RawIP::udphdr
    Perhaps experimenting with them, might yield some positive results?

    Just a thought. Not being able to test it myself. I'm afraid that's all I got.

    Best wishes

    Hey. I'm not completely useless. I can be used as a bad example.
